3i - S10 Ultra

money NO object, its not close. 3i S10 Ultra.

Because of how many robots I have to test, I don't hold onto any, usually. There are three installed at any time, they get rotated in and out of zones and then get given away pretty quickly. Small house, no room. If I was going to keep one, right now it would be the 3i S10. I didn't expect anything from it, but was blown away on performance. The tower weighs a TON, but you never have to change the water, and it is, to date, the only vacuum to completely pick up all the mulch my dog tracks in or the dog toy floof she produces.

It saddens me more than you can know that I didn't love the S10. I had SUCH high hopes, I love the brand, and the idea of the S10 (which I talked about in another thread) is magnificent. But in practice, the S10 was only ok. It struggled to navigate, it really struggled with basic thresholds, and everything that makes the K10+ fantastic, the S10 seemed to lose. I did not enjoy the E28. Enough said. I'd highly recommend a Roborock. If you can afford a Saros, the 10 and 10R are both great. If not, the Curv is fantastic, and I'd even grab an S8 MaxV Ultra, which was previously my favorite.

It's the best vacuum mop combo for a variety of reasons. You can read my review for more context. When you talk about mopping, there's some context. You've got rollers and then you have twin spinning mops or one vibrating pad. Very unpopular take but I maintain that the vibrating pad gets the best clean, And that it is the most likely to get grime off the floor. I know it doesn't make sense. You'd think it was the spinning mop pads.... There's something about the vibration that makes the singular pad better, to me. But no one has a singular mop pad on an extending arm. So if getting underneath things and around the base of things that are on your floor and up against the wall is important to you, you need those extending twin mops... I like the 3i because it's a good mop, maybe not the best but arguably a very good mop and you never have to change the water and it's sanitizes everything for you. It's very hands off.

I just tested and reviewed this one and gave it 3 out of 5 Stars. I was very unimpressed. Although I'm not done with my testing of the z70, it is not ready for prime time. The x50 was good, And I think that would be a fine purchase. I also highly recommend the saros 10r and 10. But... I was alone out of the water with the 3i S10 and no one talks about it.

For a list of every single prime day deal, [go here](https://www.reddit.com/r/RobotVacuums/comments/1ljl8wd/prime_day_deals/). These are not the cheapest robots in each band, these are my recommendations based on the final Prime Day prices. Some prices do not fall off embargo until 7/8 (Prime Day) so you may not see them until then. I will be incredibly busy during Prime Week, so may not be able to answer comments. I haven't tested every vacuum on the market, but I've tested a lot of them. Not offended if you have a differing opinion and voice that, my opinions are based on real world testing in my home, which I write about on Lifehacker. The links below will be affiliate links, you don't have to use them, but it is appreciated. # Best vacuum under $100 Controversial opinion, but I don't believe there is a best under $100. Infact, robots worth the investment under $700 are rare, as I explain in [this post.](https://www.whatrobotvacuumshouldiget.com/2025/06/20/are-budget-robot-vacuums-worth-buying/) So these robots should be viewed as tech toys you're playing around with, rather than cleaning tools that will make your life easier. Buy whatever strikes your fancy, it's unlikely to be useful as a robovac, but might be a worthy cat toy. # Best vacuum under $300 People just don't talk about the Switchbots enough in here, and I wish I knew why. Aside from having a kick ass brand identity (chonky robots that bridge a technology gap for people), they are affordable and work better than most tech products out there. I'm a huge fan of their smart home sensors and the SwitchBot button. When I got the [K10+](https://lifehacker.com/tech/switchbot-k10-plus-robot-vacuum-review) to test about 18 months ago, I was just tickled. First, it's tiny. It's like an M&M roaming your floor. At 8 inches, it cuts a tight radius around your chair legs, and can get into tiny spaces. There's no advanced tech on here, it just does a bangup job vacuuming, and then returning to its humbly small self emptying dock. Sure, there is a "mop", kinda sorta... but its just a swiffer situation, and it sucks. Ignore it (easy to do). This is a vacuum, and can more confidently manage carpet (under your bed, too!) better than most I've tried. Sure, you'll have to unclog it occasionally, but that's what you get at this price. The pro took the suction from 2500Pa to 3000Pa, which doesn't seem like much, but I can go on for hours on a nerdy rant about how much suction doesn't really matter. Whichever you get, this is the bot to beat at this price.

The only interesting nugget about the 3i when I agreed to test it was that it promised to never need a water refill. i'd just finished testing the narwal Freo Z, which has to be topped up a few times a day and an autonomous robot sounded fantastic. You shouldn't like the 3i. It looks like an exhibit in a kids science museum. It weighs like 50lbs, and there is nothing notable about the robot itself. it looks like a generic robovac. I was so blown away by the performance, I haven't shut up about it since. In the history of my testing, i have kept 3 robovacs, and this is one of them. I just place new robots I'm testing in front of it, because I'm not moving that Gdamn tower for anything, it lives there now. Theres the design: these 2 forward sweeps rotate inward, and have constant downward pressure on the floor. They're huge, and very effective. The roller doesn't get clogged. Let me repeat. I let it vacuum up dog toy floof. Mulch. Receipts. NOTHING deterred this robot. And the mop was very effective, too. Was it the best mop I've tested? No. But it ranks up there. And the water cleaning actually works, I know because for a week, we had it mop up anything we could think of. Vinegar. Black dye water. Maple syrup. Tomato juice. And not only was the resulting clean water tank crystal clear, I used PH strips to test it, and it remained stable. It just metabolized anything we ran it over. It's been a few months and I've never had to refill the water, not once. It's finally an autonomous robot, and for that, it'd be worth it at $1899. But for $1139, I don't need to think about whether its better to spend less on a high end Roborock, the 3i is cheaper. |3i S10 Ultra|$1899.99|$1139.99 w code: S10USAVE5|40%|[https://amzn.to/3GsRZlm](https://amzn.to/3GsRZlm)| |:-|:-|:-|:-|:-| # Best vacuum if you have no budget Embargo'd til 7/7 # Best vacuum if you have thresholds The good news, since many of you are trying to decide between the Saros 10/10r and the Dreame X50 Ultra, is that I can make it easy. Get the Dreame X50. You won't like the reason I recommend it, though. It's simple: the Roborock Saros 10 is not, for reasons I don't get, on Prime Day special, only the 10R is. While the 10 and 10r are [supposed](https://lifehacker.com/tech/roborock-saros-10-vs-saros-10r-robot-vacuum-comparison) to have very similar builds with a lifting chassis, they don't act like it. The 10 is a better robot than the X50, so if you can afford it, buy it. If not, the X50 is a fine robot. Genuinely. And I never got tired of watching it yeet itself over thresholds and steps. The AI onboard helped the robot get better over time at navigation, and if anything, my only complaint is that it had to return to dock all the time to top up or recharge, so cleaning a whole house took a long time to get done. Worth mentioning: I recently tested the Mova P50 Ultra, and while I thought the robot wasn't worth the price (by a lot), it did delight me in how it sailed over thresholds but also turned sideways to actively clean the threshold itself (but don't buy it, the build sucks). |Roborock Saros 10|$1599.99|$1599.99|0|[https://amzn.to/40xGAHO](https://amzn.to/40xGAHO)| |:-|:-|:-|:-|:-| |Dreame X50 Ultra|$1699.99|1199.99|29%|[https://amzn.to/3GrCzhm](https://amzn.to/3GrCzhm)| |Roborock Saros 10R|$1,599.99|1,279.99|20%|[https://amzn.to/4lFxi4W](https://amzn.to/4lFxi4W)| # Best vacuum for pets Embargo'd til 7/7 # Best vacuum if you don't want a mop Embargo'd til 7/7 # Best vacuum if you don't want an auto-emptying tower This is absurd, you should want the tower, or there's almost no point in getting a robovac to begin with.

That's good information. You know in a lot of my reviews I break down the stuff that I wasn't thrilled with into what can be improved and what can't. For instance, hardware can't be improved but software like behavior definitely could be through future updates. Overall the build of the mova really concerned me. It wasn't just that everyone has the same exact problem with the broken wheel and mova pretends like it's a new problem every single time... Like they've just never had anybody else complain about the broken wheel before. It was also that the machine wasn't putting enough downward pressure on the mop or the roller. And I think that's cuz it's just a cheap build. I extended those arms. As far as the software allowed, there were two different places where you could set that up. And yet it just still didn't get in there as much as I wanted it to. But I'm thrilled you're having a better experience and I love that you have a 3-year warranty.

the 3i S10. It doesn't get clogged, no matter how big the debris is, has an extending roller mop, and makes/cleans its own water. its totally autonomous. [https://lifehacker.com/tech/3i-s10-ultra-robot-vacuum-mop-review](https://lifehacker.com/tech/3i-s10-ultra-robot-vacuum-mop-review)

I tested oil. It didn't seem to matter. Something about the distilling process ameliorated it. We didn't detect ANY oil in the ionized water after. My editor kept trying to come up with ways to test it, but ultimately, it just seems to work. I've had it 3 months, so I cant attest to anything longer. 3i is a relatively new company, but they've been very responsive. You could ask about the battery on the website. I don't think there are knock off replacement parts of a very big ecosystem of accessories due to the youngness of the company.

this is what I got, and it works fine, though I haven't tried others.

I mean, i know its not recommended, but i use the same damn solution for ALL my robots. It comes in a giant bottle w a pump. I will say (i only know because I tried yesterday) that the 3i bottle has a suction top on it making it hard to refill. You'd be dealing with a syringe situation BUT I AM GOING TO DO EXACTLY THAT.

In 3 months I haven't refilled it.

About 1/3 of my house is carpet, and it never once got clogged, it got up everything in its path. I think the sweeps are good at agitating the carpet. I don't use the kind of obstacle tests that VW does, but it managed to get up dry dirt (my dogs pawprints that were dried), which is as quantitative has I need. The threshold is struggled with was 1" tall.

My enthusiasm is based on three factors. The first is never having to change the water. The second and arguably more important one is that this is the only robot I've ever tested that never got clogged. If you live with animals or kids, you have to breathe larger than Cheerios on your floor. And no matter what anyone says, almost every robot in the world struggles with debris that size. But I could show you video of the 3i literally eating everything on the floor. It was insane to watch. Those two front. Sweepers are the most efficient that I've ever seen. Just fantastic. And then the third is that the mop which is a roller actually extends out as opposed to a number of robots that have gotten into rollers but they don't extend. I mean I know it sounds like I'm paid by the company but I assure you, I am not. It was just the best unit I've ever used and I've held on to it.

It's a toss-up under these conditions. The freo z is a good model but a water hog. You can read my review of it. You have to change the water so often that it's a deal-breaker for me. Now they have a kit so you can wire it to your water line and you don't have to change it anymore but that's 200 bucks. So now we're talking about the cost of the freo plus the water line kit versus the l40. I keep recommending the l40 not because I thought it was a really great premium robot. It was a just fine premium robot. But when you compare it to other $500 robots, it blows them out of the water. So tldr, l40 ultra.

First of all, there is no end of the world scenario. black friday will be here in a few months. You can wait. That said, I think he l40 will be long gone by then, and I think the reason there's this BIG a discount on 3i right now is that its new. There is nothing to say that another Dreame model won't be as good a deal at BF or that I'm wrong about 3i. So, you've got a HUGE FREAKING HOUSE. that's a factor. I also have a doberman (have had them my whole life, and that spay incontinence w them is always an issue... my current rescue doesn't have it and its the first of 6 not too...). Pointis, i absolutely get it. my life is ruled by wood mulch and mud. SO... get the 3i. don't overthink it. It's the only one that can deal with the big dog level stuff. I could show you a video. it is SO worth it, and sadly, if you get the 3i, you won't experience a lesser model to know how good it is, but that's ok too.

Oy. First, you're doing great... I suffer from the same problems which is why I got into robots. And they DO help. my mood is so much better just seeing the clean floor. I do think it'll help with that. It'll still need SOME intervention, so set expectations right. but... that's ok. its going to get much better. Generally, i would say that as crappy as it is, you get more when you pay more. but that doesn't mean you NEED more... some features are just nice to have, not essential. So don't feel you NEED the 3i S10 or the Saros 10. You can get away with less. So my main concerns are the pet accidents and the cooking messes. My vacuums struggle most in the kitchen, because I drop stuff while cooking, and while it can deal with small stuff (under the size of a cheerio) bigger stuff is an issue. Also, very few mops are good enough to get out kitchen stains on their own. But I have another solution for that! If you can clean up the bigger stuff, you'll be a lot happier w the robots performance. On the pet messes... almost every vacuum out there, certainly the ones you mention, have poop avoidance. So you're good. Urine is different.... but on some level, you want the robot to get those, anyways. I don't like the Eufy bots. Ive explained why over and over again, but that's also just me. Lots of people are super happy with them, but that won't make me recommend them. I love the S8 MaxV Ultra, and its universally liked in the industry, so that's not just me. I feel like the Saros 10 is an incremental improvement over the S8, so its worth a few extra hundred bucks, but not like, 700$. I LOVE the 3i... but people have rightful concerns.. its a new company. Its VERY heavy. its a tall robot. I'm very, very happy with it, and its gotten very good reviews from other outlets like vacuum wars and tom's... so I feel pretty good about it, but I like it for you for a different reason. Its autonomous. You don't ever have to change the water, and it vacuums up EVERYTHING. ALL THE THINGS. big, small, whatever.

Unfortunately there is no vacuum that can navigate The battlefield of kids toys on the floor. So you are going to have to do a pre-sweep of those and I think you've got a good battle plan on how to do that with some scheduling. It would make your life easier and cheaper if during that sweep you also picked up anything bigger than a cheerio. Almost anything is going to be better than that Roomba, But you will might have benefited from the roombas bump and go technology because of all those toys. Any robot you pick up now is going to use lidar, which means that they should see the toys on the ground as obstacles and go around them. But if there are many of them then there just isn't going to be a whole lot of cleaning happening, just navigating. The bump and go might have moved the toys around enough to get the floor clean in the meanwhile. So, recommendations. Given that you've agreed you're going to do a pre-sweep, now we're just down to a relatively easy floor to clean and pretty low expectations of it. In which case you can buy almost any vacuum, although I think some are better than others. At the top of the list, I currently think the 3i S10 ultra is just the best there is. Aside from being the best vacuum that I have ever tested, sucking up, literally anything in its path, I love that you never have to change the mop water. And I live in a place where I benefit a little bit from a dehumidifier (The S10 pulls water from the air by being a dehumidifier). It's one of the more expensive vacuums, but wait for Prime day to see if it goes down. If that's above your budget, I would look at the roborock line. I like the 10 and 10R, But I also think the S8 Maxv ultra is great, And the curv. When we dip below those budget thresholds, I would suggest the eureka j15 Pro ultra.

I have never had a vacuum installed in my house as long as the 3i. I was actually thinking about this issue the other day because I was dumping out the water from the Mova, And I was thinking to myself how amazing it is that you just really don't smell how bad that dirty water is in any of the towers. But the moment you crack open that lid to dump it out, it smells terrible. I have never experienced a smell from the 3i and my living room floor is always filthy from my dog and mud. The tower is in my living room about 10 ft away from where I'm sitting right now. I completely acknowledge other people's experiences, I just haven't experienced it. For what it's worth, I live in a very humid place so maybe the dehumidifier mitigates it some way?

3i S10. Just got mine and it kicks roborock out of the water. Not sure about the eufy. Claims better performance than eufy.

The station is great. Seems to work fantastic other than a little bit of noise and it being huge... but the robot does need work. Mostly app functions, splitting rooms, scanning rooms only does square walls, etc. Looking forward to what it can do long term. It's quiet and fast, but both of those may not be great for it's performance 🫢 hope you can review it soon!

That is very true I should just be waiting for the flow I'm actually trying out the 3i s10 right now and I am very impressed with the water renewal system but not so much it's performance as a vacuum I'm still going to try it today it does Miss spots and does leak a little water from dirty tank

Now I changed it to 3i s10 because of your love for it! I hope 🙏 i will be able to return it??!! If I get weird smells??

I still have I8+ roomba and still use it to vacuum as most robots these days are kinda slow because of having to think so hard lol.. most won't clean to the edges sufficiently dreame x40 did cuz of arm but didn't like spin brushes leaving a gap when mopping...narwal z had for 8 mos no real problems but again vacuuming seems better with 2 rollers like roomba's..but does decently enough when mopping and vacuuming..all of them get stuck sometimes 🤔 but freo z does have great obstacle avoidance but uses a bunch of water.. e25 liked but mop didn't extend and vacuum was meh.. have 3i s10 now but it does get stuck in a few places ..doesn't like some carpets but does have water recycling and drawing it from the humidity in air..super cool! also have checked water quality and it is great! for mopping..doesn't leave weird mottleing on my white tile.. but have been hearing people having to return them cuz things go wrong with them?. I also use this one in mop and vacuum mode after roomba goes 1st cuz that seems to help it go closer to cabinets.. I clearly have an issue cuz I want to keep them all! They need better battery life, and faster processing to finish jobs..seems more innovation more problems so depends on your particular house but don't give up the roomba just yet lol I've had mine since it came out!! And it keeps going even with same battery it came with but I take care of it / them maintenance wise..

Got one of the 3i S10’s that the PDX review lady recommended, and so far I’ve loved it.

There's actually a subreddit created just last week from a fellow early KS backer: r/3iS10Ultra, albeit not a lot going on in there lol. got mine last week and after using it for about 20 hours, i can say the air-to-water plus the dirty water purification is just magic, and the roller mop extend is actually cool when it works (still, definitely needs a bit fine-tuning). The obsticle identification and avoidance need a little work, the app really need couple of major updates, overall tho, the hardware is just SO SO SOLID, like Bosch kinda solid no joke. although it's reliablity is unknown at this point, i actually have very little concern, however, i AM concerned about it's software updates, get that fixed and this machine will be a frontrunner in the robot world IMO.

My house is about 3,500 sq ft with all hardwood floors, except for two bedrooms that have few rugs. There are five people, two cats, and a dog living here, so the house can get dirty rather quickly. The first robot vacuum I owned was the Dreame X30 Ultra. It was a decent enough model but broke down after two months, and I couldn’t get it fixed on multiple attempts. I replaced it with the Roborock S8 MaxV Ultra, but it didn’t measure up to the X30. Its mopping and obstacle avoidance capabilities were subpar compared to Dreame’s, and don't even get me started on the pet hair on the roller, I decided it isn't worth the trouble and returned it within a month then resorted to manually cleaning for about 6 months. Later i found the 3i S10 Ultra and backed it on KS, it had a few hiccups initially, but the company had like 3 firmware updates within 2 weeks and resolved them. Now, it's BY FAR the best robot vacuum I’ve owned, it cleans thoroughly, hasn't gotten stuck once, and even refills its own water tank by dehumidifying and distilling air moisture. It simply gets the job done. It has been two months now, and I can’t imagine not having it, i didn't know 3i company before backing the project and only after i saw some negative comments regarding the company on their previous OEM/ODM products. But i gotta tell you, the company for sure have up their game for this 3i brand, this thing is every bit as solid as the roborock, and better than the dream, it's now $1499 on amazon, honestly i would still get it.

The efficiency of the water collection depends on where you live. I’m in Seattle, where indoor humidity level is around 30% to 45%. I haven’t refilled it once since the initial topup when i set it up. The app states that it doesn’t start collecting water if humidity gets below 30%, so that’s something to keep in mind. bills over the past two months since getting the RV have increased about less than $15. But again i got a bunch of stuff around Christmas, so I’m not sure how much of the increase is due to the 3i RV tho.

I bought the s10 ultra on Kickstarter so it was a lot cheaper than current retail price. I've only had it a few weeks but I LOVE it! I think it's still learning as it got stuck a couple of times, but the suction seems pretty good and the mopping is very good. I haven't had to fill up the water tank as it recycles the dirty water to make it clean and also sucks moisture out of the air to make new water and fill up the tank.

The bad news is that all current robots with roller mops also vacuum, and all that I know of don't have a mop-only mode. The good news is that there are a number of models which fulfill all of the other items on your want list with varying levels of quality, with more on the way. Here's the list of robots I know of on the market today, with short bouts of summarization/opinion: * SwitchBot S10+. Really cool design, with separate docking stations for the vacuum and mop water filling/emptying. Can be hooked up to plumbing. Can also empty their dehumidifier/fill their humidifier. Can extend the roller to clean right up to walls. Mixed reviews; the mop is a huge positive. * Eureka J20. Independent reviews have not been kind, though the mop has been a standout. * 3i S10 Ultra. Includes a dehumidifier to fill the clean water tank from the air, and a still to distill dirty water into clean water and send the leftovers to the vacuum dustbin. Pretty good reviews, although there's some concern about the longevity of the water management system, there is no way to empty the dirty water tank apart from the still, and the mopping has had a surprising number of poor reviews. Also can extend the roller to get close to walls. * Eufy S1/S1 Pro. Current market leader, with overall positive reviews of the mopping system. Cannot extend the mop roller to walls. Very good obstacle avoidance. (Disclaimer: I own a S1 Pro.) * Ecovacs X8/Yeedi S14. Essentially the same robot; Yeedi is the budget brand for Ecovacs. Very recently released, and the current challenger to the S1. It's still a bit early for independent reviews, but the ones out there are all over the place. There's some concern about Ecovacs/Yeedi robots generally; perception is that their quality has gone down recently. And some that have been announced, but not released yet: * Narwal Flow. * Mova Z50 Ultra.

Hi owned the 3i S10 for a few months and I would highly recommend you stay away from it. The water circulation system and on board dehydrator was amazing and actually worked but the vacuum itself was awful. The suction power was really poor and could barely pickup anything on hard wood floors. The navigation was also not great. I just purchased the Dreame X40 Master and have been very happy with it so far.

I have the narwal freo z. I've only had it about a month I think but I've noticed a good difference for me. I would say that almost any robot you're still going to have to get the corners now and then, and whether that's once a week or once a month for sweeping or mopping probably depends on your house. I have a couple of cats, they don't usually make huge messes but they do get litter everywhere in the kitchen near where their litter box is. One of the huge pluses for me is that I have scheduled it to tidy that up just that one zone, and around the food dishes, once a night. And I have it hit the litter area again in the morning before I get up. I schedule a daily full house vacuum, and then a full house vacuum and mop on one day of the week. One of the other big bonuses I noticed besides the cat litter is that my floor is just not normally sticky in the kitchen. This is awesome because I have a kid and teenagers like to drip things absent-mindedly or maybe conscious-mindedly.... But the point is they don't often pick up their own spills. 😂 So it helps there. I'm REALLY intrigued by this one https://amzn.to/4fVD5jF but people have warned about the quality of the company. It just came out but it's incredibly expensive. It actually extends to the wall for the mopping and has a bunch of other really cool features I'm considering.... I just don't know if the object avoidance is good as the one I have. Overall, I like the vacuum I have but there are a lot of areas that they can improve on over the next few years.

Testing 3i S10 ultra. Navigation is a little better, but it tends to make one mistake in the navigation and "learn" it hence repeating it since then, similarly to X9. I guess it has to do with this pseudo AI algorithms... Mopping on the X9 is superior but not that much. Vacuuming is superior on the X9. Noise on the 3i is next to zero. 3i is far more wonderful. Both are not work 1k off my pocket, at least 3i is bringing innovation.

I just picked up the 3i s10 ultra. What i love about this thing is the water reclamation and distillation process. I've only filled it once in 2 weeks since I got it. It pulls water from the air as a dehumidifier and also reclaim the dirty water it uses and cleans it for reuse. It has a built in camera which it uses to take photos of obstacles that it encounters along its way. I have a 1400 soft apartment 2 cats and my girlfriends dog when she comes over. It's pretty thorough in it's mopping capability and uses a roller mop. For reference I'm coming from a roborock s8 pro ultra that broke down after just over a year. To be honest that vacuum was aces until it wasn't anymore. The app for the 3i is a bit like the roborock so but hard to set up. I suspect most ui are the same now a days. The unit is heavy due to the base having the humidifier and distillation mechanisms but I'm not moving this thing around every day. I suffer from sinus issues and allergies and need every bit of humidity to sleep comfortably. I placed the machine in my main bathroom so as to pull water from the air in that room and use separate humidistats to measure humidity throughout my place and have one just above where the robot is placed. The levels I see on my humidistat is the same i see in the app for reference and there's no significant drop making it uncomfortable for me. This is huge for me as I used to have to empty waste water and fill fresh water and soap weekly on my previous robot vacuum. So far it's doing a great job keeping up with my place even with the dog coming in and out from walks all day. It's not as loud vacuum wise as the roborock on max vacuum power mode and the roller mop slides out to one side when cleaning the perimeter of rooms to get up close to the molding. I've watched it do that and it's but that impressive but better than what I previously had which only got a close as the body of the machine would permit. I'm still putting it to the test keeping an eye on the mapping obstacle avoidance and completing full runs and coverage. Good luck hope this helps.

3i S10 best most technologically advanced robot. Using it for 2 weeks and far surpassed all other robots I returned.

The best cost no object vac-mop is the 3i S10 I had the Eufy S1 pro and the Flagship Eureka J 15 and the 3i is better at mopping and on strong or max suction is a great vacuum. You also don’t need to deal with a disgusting dirty water tank and also has a self filling clean water tank and incredible obstacle avoidance.

I have been using my 3i S10 robot for close to 2 months I have used and returned to Amazon the Eufy S1 pro Omni- which was great at mopping but terrible at vacuuming carpet- I also returned the Eufy X8 pro and Flagship Eureka J15. The 3i is the best robot so far it has incredible suction when you set it at either strong or Max. If you need serious mopping you can have it mop 2x I never filled the water tank since set up due to the dehumidifier and water distillation. Also no disgusting dirt water tank to smell and dump and the dirty water splatters everywhere. it also has excellent obstacle avoidance and a pretty decent battery

I returned my S1 pro Omni As I was not happy with the edge cleaning when mopping, poor carpet pick up and complicated waste water tank on the robot. I now use the 3i S10 and it is in another league as far as cleaning and vacuuming. Also it does not have a dirty water tank and you don’t even have to refill the clean water tank- I will be posting a video as I love this machine.

They have been making robots for a long time for Xiomi. They hired the best engineers to develop this robot. My house has never been this clean all the time.

You can talk all you want- I have returned 5 robot vacuum mop robots 4 from Eufy including the S1 pro and Eureka J15 flagship The 3i S 10 that I am using now is better in every way The biggest complaint being carpet cleaning is overcome by making sure the carpet suction mode is set to max suction- which now rivals the cleaning ability of my upright SEBO G1 It mops great and makes it own water Also the dirty water gets distilled by boiling it and gets reused It works really well And customer support is very helpful and responsive.

I returned the S1 Pro due to poor carpet vacuuming and a poorly designed waste water tank on the robot. I had a. $400 coupon on Amazon and bought the 3i S 10 It is so far way better than the S1. Only problem is max suction for carpet drains the battery faster but - it has enough juice to do my mostly carpeted upstairs.

I just noticed that when it came time to clean the wastewater tank, it was very difficult to take out the number 1,2&3 tabs . In fact, it was so difficult that when I was pulling up on the metal bar to take it out of the water tank it actually broke. This is a bad design and is much better on the 3i S-10

The 3i S10 set at max suction is great.
