The J15 Ultra, with the razor cutters on the roller, is still the right vacuum. Buy it off the Eureka site, where its $550, if you can comfortably stretch. Don't get the Mova. The Dreame L40 Ultra is very good and would be a GREAT buy-remember reviewers bought it at 3x the price and like me, were reviewing it as a premium robot against other premium robots. For under $500? No brainer, its fantastic. Does that make sense? I think you have 2 great options. the L40 ultra or the J15 Ultra (through the Eureka website).
r/RobotVacuums • Prime Day last chance- a few hours left to score PD deals. Are you on the fence? Let's cut through it. ->You can always add it later, but if you can comfortably afford it, I think it's a reasonable add-on
r/RobotVacuums • Prime Day last chance- a few hours left to score PD deals. Are you on the fence? Let's cut through it. ->If you can comfortably afford it and get it there, I'd get the 3i S10 But I don't know that you can. After that it's deprecating returns. So I would look at the saros 10, and then the s8 maxv ultra. Take a look at those and let me know what you think and if we need to go lower. But I'm going to be honest, the house that you're describing and the situation, need something that can handle larger debris...
r/RobotVacuums • Prime Day last chance- a few hours left to score PD deals. Are you on the fence? Let's cut through it. ->I only tested the Eureka in an attempt to make sure I was branching out from the usual suspects (Dreame, Roborock, Ecovacs, Eufy). I didn't expect much because honestly, legacy brands that try to transition to smart home always screw it up, IMO. So far, I've tested three of the J15 line. And they're not the best robovacs I've ever tested... usually higher end models inhabit that space. But I admit I was surprised by how well they performed. I found myself noticing the quiet, and this was the model that helped drill home how important that triad is under the robot. The sweep, the roller, the suction. No matter how high the Pa is, if those aren't in the right design, the suction doesn't pull enough debris. I guess my point is that it turned out to be a very reliable model, it was consistent. The razor did a very good job cutting hair so it didn't cause problems. I thought the app was very easy to use. I wasn't overwhelmed. My main complaint is that the robot is overly tall and the tower not very attractive. That's why I recommend them as much as I do. For under $500, they're an exceptional pick. (when on sale, obvs)
r/RobotVacuums • Has anyone tried the Eureka J15 Max Ultra? ->I literally just had this convo in a PM w someone from rtings. I do. I thought the L40 was a better robot than most Dreame models, and while I didn't find it worth the value at the original price, I do think its worth it on sale. The P10 doesn't have longevity, IMO, because I think they skimp on hardware to keep the costs down. That's my hot take, and I totally get that I'm an island (I also dislike Eufy, and people in this sub love them) but I use a different testing method than most other testers (I test in an actual home setting), and I stand by it. The thing is, in that band, the L40 is my last pick. I'd get either the J15 or 3i before I got the L40. In the end, the model you pick is likely going to be fine, regardless. you haven't tested 100 robovacs, so like a virgin on your wedding night, it's all probably gonna seem great. if you feel strongly about the P10, go for it.
r/RobotVacuums • My Budget is $500: Dreame L40 Ultra vs Dreame L40s Ultra CE ->3i is only new because they have been making robots for everybody else for many years. Eureka is not a new brand at all. The j15 is theirs. Eureka has been in vacuums forever. I mean I would go with the most expensive one that you can reasonably afford.
r/RobotVacuums • My Budget is $500: Dreame L40 Ultra vs Dreame L40s Ultra CE ->long hair, you need a robot with a razor cutter. under 400 isn't very realistic...but this model is within reach. [Eureka J15 Ultra](https://amzn.to/4o4MPMA) 489.99
r/RobotVacuums • Big Deal Day Recommendations by Price Band - These are the robots I'd buy ->Hey. I've listed every [single price](https://www.reddit.com/r/RobotVacuums/comments/1nvsulx/every_robovac_on_sale_for_amazon_big_deal_days/) for the Big Deal Days sale, and my recommendations [per price band](https://www.reddit.com/r/RobotVacuums/comments/1nzbtex/big_deal_day_recommendations_by_price_band_these/). However, I'm getting the same questions over and over, so here's some additional context. # Best Robot for Long Hair (human or pet) Hair is the foil of all robot vacuums. It doesn't just wrap around the rollers, it also gets wrapped around the sweeps and the wheels, and while it doesn't hurt the robot, it will make it less effective, and require you to clean it more often. This isn't a problem with short haired pets (they have a different problem). Yes, having high suction is important, but it doesn't always translate to getting more debris up. In the case of long hair, nothing beats a razor cutter on the robot, and the only line that has one that I recommend is the Eureka J15 line. I like this line a lot for other reasons, too, but if you've got a long hair problem, this is the answer. There are J15s at a number of price points. [Eureka J15 Ultra](https://amzn.to/4gUYACY) [Eureka J15 Evo Ultra](https://amzn.to/42tMbQF) [Eureka J15 Max Ultra](https://amzn.to/46UkK3x) # Best Robot for Short Haired Pets Now, you have a different problem, which is sticky hair. Short hair sticks to the floor, it climbs the walls, and you need a sweep that will effectively get it off the ground and move it toward the roller, where the vacuum can capture it. The sweep plays a critical role here, and the sweeps that are most effective are large, in constant contact w the ground, and move in opposite directions. Eufy e25/e28 have the right design for this, but I don't recommend them for other reasons. The models that I've found that do this best are the 3i G10, P10 and S10. I love these models for other reasons, but those sweeps seal the deal for me on short hair. It's just a bonus that they are also the only models that can suck up cat litter without clogging. [3i G10+](https://amzn.to/48znS7N) [3i P10 Ultra](https://amzn.to/4h1Sy3y) [3i S10 Ultra](https://amzn.to/4o7hKIe) # Best Robot for Carpet If you've got a whole house of carpet, I like the Dreame X50, Dreame L40, Eureka J15 Ultra, and Switchbot K11+. That's not to say other robots suck at vacuuming, they don't. But I like these models specifically on carpet, and if you've just got one room with carpet, consider getting the K11+ for that room alone. Its cheap and great at navigating under beds, etc. [Dreame X50 Ultra](https://amzn.to/4h77Wfa) [Dreame L40 Ultra](https://amzn.to/48Rswhk) [Eureka J15 Ultra](https://amzn.to/4gUYACY) [SwitchBot Robot Vacuum K11+](https://amzn.to/4mOxq1O) # Best Robot for LVP Lots of people have LVP and want something specialized for it. In truth, there's nothing special about it. A robot good at hard floors will work for LVP. There aren't really robots that leave a lot of water behind anymore. # Best Robot for Area Rugs This is not a model specific problem, its a rug problem. Rugs have to be well anchored to the ground (a grip pad isn't going to cut it forever), and the lower the profile, the better. Think Ruggables. If a rug starts to roll up on an end, the robot is going to have trouble. If a rug has fringe, its a bad match for a robot. Even bathroom rugs are rough for robots. All that said, a robot with a lifting chassis is going to have an easier time getting onto a rug. Think X50, Saros 10/10r, CurvX. [Dreame X50 Ultra](https://amzn.to/4h77Wfa) [Roborock Qrevo CurvX](https://amzn.to/48PvS4j) [Saros 10/10r](https://amzn.to/4nyiwy5) # Best Robot for Small Spaces Get a Switchbot K11+. That is all. It's a vacuum only, but costs next to nothing, and is shockingly full of premium features. It also is a effective vacuum, getting into places no other robot can because of its size. [SwitchBot Robot Vacuum K11+](https://amzn.to/4mOxq1O) # Best Robot for Corners This doesn't exist. No robot is great at corners. In fact, most robots aren't great at the "edges" of rooms, they're mostly good at the main open area of a room. You have to let this go. The best you can do is get a robot with extending sweeps/brushes. A lot of robots have these now, and they're one of the best features. # Best Robot if You're Hellbent on a Roller Mop Everyone in this Reddit forum is convinced rollers are the end all/be all of mops. I disagree. They're fine. But if you're just absolutely determined to get one, get the Flow. Eufy's e25/e28 models were riddled with errors, and Dreame's roller mop leaks and streaks. The Flow was easily the best of the bunch. [Narwal Flow](https://amzn.to/3IxMoLX) # Best Robot for People with ADHD Also, my favorite robot. The point of a robot, for me, is autonomy. I want it to do the damn job, with as little required of me as possible. Otherwise, I might as well do the job myself. While most robots do help, they also require upkeep and new, consistent input. Change the water, change the filter, unclog it, find it where it got stuck on a cord, etc. And then, I tried the 3i S10, which i had zero expectations of, because I'd never heard of the brand. This is the robot to get if you're overwhelmed and just want the job done. It vacuums EVERYTHING without clogging. Does it silently. It mops well, and both makes its own water and sanitizes the water it recycles so you never have to change the water. It's got downsides: its effing HUGE and heavy. It looks like an exhibit at a science museum. Its expensive, and some people say it smells musty (it makes water via a dehumidifier, so that makes sense). But readers, I would marry mine. [3i S10 Ultra](https://amzn.to/4o7hKIe) \------------------------------- For some context, I [write about robovacs](https://www.reddit.com/r/RobotVacuums/comments/1l48fms/i_write_about_robot_vacuums_for_a_living_ama/) both for an online pub and my own site. I shared similar information and advice for [Prime Day](https://www.reddit.com/r/RobotVacuums/comments/1ljl8wd/prime_day_deals/), and people were generally pretty [happy](https://www.reddit.com/r/RobotVacuums/comments/1m0sjou/amanda_amanda_amanda_the_dreame_l40_is_amazing/) w the recommendations from the feedback.

r/RobotVacuums • Big Deal Day Recommendations by House Needs ->Hi. I also have long hair, and I'm from AZ so I get the DUST. So, at this budget, you're not going to get it all.... large debris like cheerios you might get away with, but you're absolutely going to have to do a sweep for big baby/kid messes before running the robot. Depends HOW shaggy the carpet is, whether it'll be problematic. But, since you're dealing with long hair, get a [Eureka J15 Ultra](https://amzn.to/4gUYACY). it has a razor that cuts the hair so its not a problem. When you get it, stock up on extra filters. That AZ dust kills the filters on these vacuums, so change it out every 3 months, and clean it once a month.
r/RobotVacuums • Trying to grab a deal before the end of Prime Day? One on one advice. ->Skip both. Get a [Eureka J15 Ultra](https://amzn.to/4gUYACY) or a [3i P10 Ultra](https://amzn.to/4h1Sy3y). Short fur makes me lean towards the 3i, but since its half carpet, the J15 is also great. I like that both of these have giant sweeps that are in constant contact with the floor, and are smoking deals under $500.
r/RobotVacuums • Trying to grab a deal before the end of Prime Day? One on one advice. ->Get a [Eureka J15 Ultra](https://amzn.to/4gUYACY). Under budget, cuts long hair, and honestly, you don't need much. no pets, no kids, just dust? Almost anything is going to be great. But this is the one I'd get.
r/RobotVacuums • Trying to grab a deal before the end of Prime Day? One on one advice. ->ugh. i have some tough news, buddy. I also have a dog and puppy prints are a stain. think about your floor this way. When stains are wet, robots do a fine job, its just about viscosity of the stain. wet muddy pawprints requires more passes than clean wet pawprints. But DRY pawprints? the first pass is just to wet them. You need subsequent passes to get that moisture through the stain and then remove it. Muddy prints? takes longer. And no robot has the same downward pressure you do on a mop. Point being... don't set expectations too high on this metric. Robots will fail. But when i say the vibrating mop pad is better than spinning mops? I'm referring to this specific situation. That all said, yeah.... I like the [Eureka J15 Ultra](https://amzn.to/4gUYACY).
r/RobotVacuums • Trying to grab a deal before the end of Prime Day? One on one advice. ->oh Canada.... ugh. The truth us you don't have the robot I want you to get (the 3i S10 Ultra) and every other one is going not be up to the challenge of your household. So... here's what I think. Get a fleet. Get a fleet of cheaper robots, one per floor, so they each have a tiny domain, and are less likely to get clogged by kid mess and long hair. AND... if one goes out of commission, you've got 2 back ups. I'd recommend the [Eureka J15 Ultra](https://amzn.to/4gUYACY) because of the long hair and messes. But no matter what, you're going to have to sweep for kids toys and dropped food. No robot is going to handle those.
r/RobotVacuums • Trying to grab a deal before the end of Prime Day? One on one advice. ->Honestly, you don't need much. You've got a clean floor and you're just looking to keep it clean. Get a [Eureka J15 Ultra](https://amzn.to/4gUYACY) or a [3i P10 Ultra](https://amzn.to/4h1Sy3y), but honestly, you may be able to get away with a [3i G10+](https://amzn.to/48znS7N).
r/RobotVacuums • Trying to grab a deal before the end of Prime Day? One on one advice. ->Yup. You're screwed on the textured tile and as someone who lives w that as well, it blows. I've got some suggestions separately for that. For the dust bunnies.... I'm thinking you've got 2 options. The [Eureka J15 Ultra](https://amzn.to/4gUYACY) which will dispatch the long hair w a razor blade, and still be a great mop and vacuum, or the [3i P10 Ultra](https://amzn.to/4h1Sy3y), as you suggested. Skip the other options. It's a toss up because the 3i is better at capturing debris, but the j15 will handle the hair better.
r/RobotVacuums • Trying to grab a deal before the end of Prime Day? One on one advice. ->I mean, I don't know that's true. if you could stretch, man I'd love to see you w a 3i S10, but its $1100. I think it could handle it all including that maintenance in between. But yeah.... you're gonna need to do some manual work too. I mean, Roombas are not awesome. I'm sorry about the Roborock issue. For that much hair, I guess I'd say, go with a [Eureka J15 Ultra](https://amzn.to/4gUYACY), but really, all of this is a temporary band aid at best.
r/RobotVacuums • Trying to grab a deal before the end of Prime Day? One on one advice. ->nice small space, you just have a lot of hair. Get a [3i P10 Ultra](https://amzn.to/4h1Sy3y). Its a nice, middle of the road option.
r/RobotVacuums • Trying to grab a deal before the end of Prime Day? One on one advice. ->don't get a shark. get the [Eureka J15 Ultra](https://amzn.to/4gUYACY).
r/RobotVacuums • Trying to grab a deal before the end of Prime Day? One on one advice. ->Get a [Eureka J15 Ultra](https://amzn.to/4gUYACY). Under $500, equally good on carpet and hardwood, and its a great mop and vacuum, equally. You don't need much. No pets, no big challenges. You're going to be happy with most robots.
r/RobotVacuums • Looking for a Robot Vacuum with Mop under $500 ->yeah. for the hair, you need something with razors in the roller. I think the Eureka J15 line is really unparalleled in that way. And I like the machine generally, too. I think its a good value when on sale. The larger sweepers are effective at getting debris off the floor. I've tried the J15 ultra, the J15 pro and the J15 max pro and I've been happy w all three. You can see them all here: [https://amzn.to/4iiCA5F](https://amzn.to/4iiCA5F) (<- that's an affiliate link, btw)
r/RobotVacuums • Every Black Friday Deal on Robovacs ->Ok so I have bought 3 robovacs in the last month. a cheap roborock with no dock, a j15 ultra and a ecovacs omni. By far the best mapping was roborock. But the other two vacs are better as they mop and have docks. The eureka j15 pro ultra is the best but the ecovacs isn't much worse for half the price. I paid 250 for the roborock, 650 for the ecovacs and 1200 for the eureka j15. My favourite is the j15 pro ultra and its not much different to the j15 ultra going for 900 now. The battery lasts way longer than the ecovacs omni but both do about the same level of cleaning. I run both mine twice a day just to see how they go and my floors have never been cleaner, whatever way you go a robot vac is awesome. Just schedule in and it cleans, best m9ney I've spent in a while. And yes I do need a couple as I have a large house. This is australia pricing aswell and I bought on the Amazon sales so they were cheap.
r/RobotVacuums • Need Real Feedback Before I Drop $$$ – Roborock, Dreame, Ecovacs, Eufy… (or Others) - Help Me Decide ->How does the eureka do with thresholds?? I have .25inch for the kitchen and bathroom. 90% hardwood, 2 area rugs
r/RobotVacuums • Big Deal Day Recommendations by Price Band - These are the robots I'd buy ->I think you’ve sold me on this one, I had been using gpt to compare the d20 pro plus to the L10 ultra, I preferred the round mop instead of the single pad. Hadn’t thought about eureka but I also like that you mentioned the app was clean and setup was smooth. Thanks a lot!!
r/RobotVacuums • Big Deal Day Recommendations by Price Band - These are the robots I'd buy ->Sweet, thank you! I too am wishing it wasnt so tall so it would fit under my couch which is 4.25”, but you can’t have it all. Really appreciate your help with these write ups Edit:typos
r/RobotVacuums • Big Deal Day Recommendations by Price Band - These are the robots I'd buy ->My Eureka J15 has a hair cutter built into it to prevent it from getting tangled. I haven't had it for very long yet, so I can't really say if it's good or not yet. My old roomba was terrible with pet hair, it wouldn't vacuum it up at all, and would just leave logs of hair around the floor.
r/RobotVacuums • Best robot vacuum for pet owners? / For dog hair ->I have 3 poodles that don’t shed but do run in and out with dirty feet all day and a long hair cat plus a pitbull. In case you don’t know pit bulls are super shedders. That’s why they make pjs especially to contain it all. We also heat with wood which means all kinds of bits getting tracked in. I’ve used Roombas for years and still run 2. However I just got a Eureka J15 beginning of December and I am loving it so far. It’s much quieter. It is faster. And so far, unlike the Roombas, I have never had to manually clear the vacuum bin. I have run it 1-2 times a day every day since we have had it.
r/RobotVacuums • Which robot vacuum is a workhorse? ->The Eureka J15 already does these things and is great. Highly recommend it. Super clean floors and no chemicals needed.
r/RobotVacuums • CES just dropped a ton of new robot vacuums—where are we headed? ->It lifts its mops when transitioning floor types, and it does just fine on my floors. No it doesn’t mop carpet but I wouldn’t expect any robot to be good at deep cleaning a carpet, and adding moisture to carpet regularly is not going to be good. The J15 has done great for me, enough that I bought a second one.
r/RobotVacuums • CES just dropped a ton of new robot vacuums—where are we headed? ->Sounds like you need a new vacuum. Check out the Eureka J15. It's self-cleaning and shreds the hair when it docks. 16500 Pa of suction power also sucks every bit of hair and dust. It really made a huge difference for my place with two cats. It's like I have a wife now, but she only comes to clean twice a day.
r/RobotVacuums • Am I expecting too much of my vacuum? ->Only thing I'm going to tell you to do is do NOT buy the J15 eureka. IF it lasted at least 3 months, I would probably recommend it, but they are complete garbage. My brother has gone through the same Fiasco with them. They're absolute junk.
r/RobotVacuums • So... Can robovac actually deep clean? If so, which one? ->Just my two cents but I really wish you didn't take pricing into consideration whatsoever. I'm on my second go-around trying to determine what robot to purchase after making the huge mistake of buying the Eureka j15. I don't care about the price. I care about does it actually do the job and is it going to last because even $800-$1000 robot that doesn't last 3 months isn't worth $50 to me
r/RobotVacuums • Big Changes on the Vacuum Wars Top 20 List Today ->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.
