ECOVACS - DEEBOT X9 PRO Omni Robot Vacuum and Mop

My comment disappeared sadly. I will rewrite in short. VacuumWars just like smarthomeassistent have rated the X9 quite highly. It is a premium, top of the range model, with a lot of great features and good vacuuming / mopping capabilities. The robot may not be on first place anymore, but I would argue that telling the difference between the top 10 robots is quite hard. Both of these reviewers use a quantitative method, by judging the performance using a point system and tests which remove qualitative / objective opinions. As a comparison you can take Justadad, he does not review robots, he just rambles, looks at the floor and says “yeah it’s good”. He is the “reviewer” you should only watch if you want a “feel” for a robot. TLDR: He can’t fake these tests, they are quantitative tests which are weighted by what he feels is important.

Even smarthomeassistent rates it as a good robot. Maybe not number one, but all of these tests are within tolerance of each other. I would argue that the cleaning power comparison of the top 20 is unlikely to be “noticeable”. VacuumWars has a point system, this makes sure any review is as “unbiased” as possible. They cannot cheat it, because what the robot achieves in these tests is what the robot gets in points. They can design the tests such that a certain style of mop for example gets more points. The rollers get more points because the weighting of “water left behind” is so high. And the relevance of that is objective. And yes, they will be biased, for example their support for iRobot, but most reviewers do it. Yet the numbers don’t lie, they are not qualitative like “just a dad” but quantitative, so actual numbers.

I think x9 will do better on carpets, since they have upgraded the airflow system for stronger suction power. Hope you like your new robot and please share more when it arrives.

The roller mop is probably better in terms of cleaning results. If you get one with a station, it can wash and dry itself. I usually just wait for the deebot to finish, let the roller mop clean and dry itself, and then do a quick check to make sure there’s nothing left on it.

i had a roller mop ecovacs x9 and it does not get the edges, cannot run in a straight line. poor app. and the base station accumulates dirt and pet hair from mop cleaning i have 2 labs. good concept poor execution. sent it back. getting mova v50 on sale

Yea, if you want to see "next level" in this particular test, take a look at Ecovacs X9 Pro Omni - it has a continuous roller which means that it actually actively picks up liquid from the floor into a dirty water tank, and goes to empty it as soon as the tank is full. So it would have the floor dry in a single pass.

I’d get the T80 in your situation. The X9 has the ability to lift mop, vacuum and side brush independently. I don’t think that benefits you much if you do not have much of a rugged area. I have a X9 and E25, and I find the X9 to do a much better job mopping and require much less maintenance of the mop and dirty water tank. E25 was a louder vacuum and worked very fast. X9 while very slow in comparison it mopped with very little noise.

Eufy E25/28 gets recommended here alot. Lots of people already reviewed them of course, I owned one for a whole month and want to share a few things in my experience. Background, for comparison: I have/had Xiaomi gen 1 robot vacuum, a Roomba J7, a Dreame L10s Ultra gen 1 with tricut brush, and a Switchbot S10. I also have a Tineco upright floor mopper as well as a Sebo E3 canister vacuum. It's been a while since i bought a recent model robotic vacuum and I been really wanting to get either a Matic or Mova Z50 but it seems that they are never coming to Canada, so what the heck give Eufy E25 a try. We have a 18month baby who really likes to throw food and spill milk on the floor, so you get why i have to have a roller mop. We have about 1400 sqft of mixed carpet, hardwood, and tile surfaces on the floor that this vacuum is set up on. We have a room with dark blue carpet, and we have a white siberian husky, so any strand of hair not picked up is very visible. Now, pros: \- Very fast (it does the job quickly and goes back to chill), much quicker than the Dreame L10s OG that im used too (and obviously light years ahead of the Roomba J7) \- Seems reliable (i have not had any software or navigational glitch), the only time it got stuck was from ingesting a bottle cap that my toddler left on the carpet so you know what obstacle it might not try to avoid \- Has no issue going over the feet of this standing desk, my Dreame L10s OG used to really struggle with it and lose side brushes on it all the time. \- Picked up dog hair decently well, not every single strand of course but its more than good enough. On most people's carpet you wont notice anything, but because i have a white dog and dark blue carpet i can see some strands left behind - again i don't think even my Sebo E3 with motorized head can pick up every strand of hair on that carpet. \- The anti-tangle brush design is amazing, after a whole month, the station bag is full of dog hair, and not a single strand was stuck in the roller. I think this works better than the tricut style of roller which seems to become less effective over time. \- Noise level is acceptable. It's much quieter than the Dreame L10s OG and Roomba J7 that Im used too. You can definately use it while you are in the same room. The self emptying station is also quieter in comparison but emptying the vacuum can still be a nuisance. However, it is noticeable louder than Ecovacs X9 that i just got today (which does not have as much high pitch motor noise both when vacuuming and emptying) \- I think the app is simple and good enough, i see people complaining about it here, but I think that its simplicity is arguably a better user experience - you dont need to customize every aspect of cleaning of every room and such - it does more than enough Cons: \- I see people recommending it for mopping alot here, frankly I think it sucks. I think its roller mop implementation has some issues regarding the water scraper design, here is why: when you run the mop, it leaves alot of water behind, and does not appear to be scraping enough dirty water out of the roller to collect in dirty water tank. After mopping is finished, there is sooo little dirty water in the dirty water tank it is concerning - and thats after using water to clean the roller at the station. I suspect that most of the collected dirty water is from mop washing at the station and not from collection during mopping. This would explain why my floor is so wet from mopping, and after it dries it feels a little gritty, like stuff got left behind and then evaporated. Its not collecting dirty water at the same ratio that my old Tineco upright handheld mopper does. For comparison, I also just bought a Ecovacs X9 and used it for the first time earlier today, that thing almost collected as much water as it used. If the roller mop fails to collect dirty water back from the floor, it's not doing much better than just spinning/vibrating pads. I still think that it probably cleans a little better than the Switchbot S10 because that thing does not wet the floor enough even on wettest setting, but i have no way to tell which one is doing a better job collect dirty water because the K10s is plumbed in. \- the mop drying: I live in a relatively dry climate, and I set it to dry the mop using the standard 5 hour max time. I ran it in the evening and went to check it next morning, the roller mop is still a little damp, but only on the upper side of it. Which makes me wonder if this thing does not rotate the roller when it dries? In any case the drying is not sufficient and definitely not as thorough as the S10 \- the maintenance: the mopper mechanism, the scraper, and dirty water tank, gather more crap than you expect. I'd clean it after a week and there is quite a bit of wet grimes build up in the scraper mechanism. And because the roller doesn't dry very well, it started to smell. I eventually started taking it once a week and pour boiling hot water over it, that got rid of the smell. I also empty the dirty water tank basically almost daily, rinse it, and leave it open to dry - which stopped it from smelling too. Overall i still find it easier to use and maintain than a upright handheld mopper, because i can set it to run and go about my other business, and just remove the roller to dry and empty the dirty tank at the end, still saves a bunch of time in comparison. Overall, I think its a really good tool to have coming from a handheld upright roller mop, but the biggest complain is the roller scraper design, i dont think its doing a good job removing dirty water and has such a complicated design that is not very easy to clean. If Eufy can improve this aspect better to at least be collecting some actual dirty water, and provide the plumbing hook up like the S1 Pro, this would be perfect, I hope they can make it happen with the upcoming S2 Pro.

I’ve only used it once so far but there is no noticeable difference yet

The prime day sale is probably what pushed me to get X9 otherwise I would have gotten T80. X9 probably has a bit better obstacle avoidance at least on paper but who knows what difference it makes. I’m definitely keeping the X9 over the E25 now.

I think you may have a defective sensor somewhere on the robot (I’d just return it and buy another one). I have not notice me any deficiency from this bot without spinning lidar tower. For example this the clean from last night, the only down side I would say with x9 is that the battery life is a little short and it had to return to charge a few times: https://preview.redd.it/p1ge857wpvcf1.jpeg?width=1125&format=pjpg&auto=webp&s=56eb99c3eeaefad86cd11b8f4719c1d11c7a9f6d

I’d get the Ecovacs T80. I have an Ecovacs X9 which is similar for mopping and it’s better than the Eufy E25 that I had.

I also mostly agree with your findings and wrote about it separately just few days ago. I had an E25 and it does a number of things well, it cleaned fast and covered larger area without running out of battery, I didn’t have navigational issue with it either. What I find most annoying is that it did not collect dirty water from the roller mop effectively and most of it was left on the floor to evaporate. The E25 has two plastic scrapers that are part of the onboard dirty water tank structure, they are fixed in place scrapping against the roller. On the Ecovacs X9, the scraper is a stainless steel metal piece mounted on spring pushing it against the roller. This is pretty significant design difference, I don’t think the E25/28 will ever be as effective. On the revised tank they sent you, they are probably tuning the spacing between the scraper and roller, if it’s too tight it might make the motor stuck, if it’s too loose it won’t scrape the roller effectively. In my opinion the spring loaded scraper design on the Ecovacs X9/T80 is superior. The Ecovacs X9 also does a better job cleanings its roller, keeps it free of odour because of hot water washing, and it keeps the base station mop washing tray cleaner than the Eufy E25. There is a dirty water tray on the robot next to the mop which is also removable and easier to clean in my opinion.

Ecovacs X9 does hot water washing and drying, it’s the one mopping bot I’ve used that hasn’t developed any smell.

I like our Ecovacs X9. It’s working well so far and does a really good job maintaining itself.

I have the X9 Pro from Ecovacs. I set it on a daily schedule, it cleans when I take my dog out for a walk. I still vacuum inaccessible areas every few days, but it definitely cut down my overall cleaning load.

I got a ecovacs Deebot x9 pro omni for 647$. Im just wondering would it be worth getting a Roborock/Dreame 2-400$ more? x50/Saros etc.

I just gave that model a 3 out of 5 stars. So... not so much. [https://lifehacker.com/tech/ecovacs-deebot-x9-pro-omni-review](https://lifehacker.com/tech/ecovacs-deebot-x9-pro-omni-review)

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.

Hey. first of all, that just sucks. it was expensive, and you were excited, and that always blows. I hope you've got an easy return path. A few things I wanted to add. I think Vacuum Wars is great, it just needs context. They use an obstacle course, and I would view their testing as benchmarking. As you've pointed out, real world use is very different. Internal LiDAR isn't terrible, its quite good in the 10R, but if I'd only tested the X9, I'd feel the same way as you. It's interesting, because people go on about roller mops, for instance, but its more about the implementation than the tool. People have different experiences. I did not like the X9, but someone just this morning went on and on about how great it had been for them, and surely I must have had a bum test unit.

# [Under $300](https://amzn.to/48R0G4J) Generally speaking, I think its rare you find a great robot at this price, and I've discussed why there's some sense in [not spending the money on real discount robots](https://www.whatrobotvacuumshouldiget.com/2025/06/20/are-budget-robot-vacuums-worth-buying/). Still... there are a few gems worth looking at, as more expensive models drop under this threshold. *If I were buying at this price point, I'd get:* If you're more concerned about a mop, get the 3i. (its great at both, to be clear, but it has the best mop of the bunch). I really like the 3i brand, they're not new, they've been making robots for other companies for years. The G10 is stripped down from premium models, but it had the same sweeper>roller design that is so effective on the higher end models. *If you don't want to go with my top recommendation, I also recommend:* If you've got a smaller place, or a place with many floor objects, try a Switchbot. Because they're so small, they can get between chair legs and make a small radius around things. Switchbot just doesn't get enough attention, IMO. Lots of people purchased the [K10+ Pro](https://lifehacker.com/tech/switchbot-k10-plus-robot-vacuum-review) on my recommendation during Prime Day and have posted about how happy they are. The 11 made the tower smaller and improved some other specs, but is mostly the same model. The perfect apartment, studio, or office vac. Performs spectacularly well as a vacuum, particularly given the price and stats, but it is ONLY a vacuum. I, personally, do not enjoy Eufy models, and on the whole, [did not enjoy the E20](https://lifehacker.com/tech/eufys-e20-robot-vacuum-ces-2025). I thought it was clunky and not particularly great at any of the 3 things it was trying to do, but people in this sub LOVE Eufy, so at this price point, if you're so determined, this is the one I'd get. In a similar vein, if you love Roborock, a brand I usually recommend highly, I usually think you should grab the most expensive one you can afford (with some exceptions). In this case, its the Q10 X5+, which is the least expensive RR model with auto empty. |Model|Original Price|Sale Price|Discount| |:-|:-|:-|:-| |[SwitchBot Robot Vacuum K11+](https://www.amazon.com/shop/amandablumstiktok/list/1VV8DEM3PE45Q?ref_=cm_sw_r_cp_ud_aip_sf_list_spv_s_ons_mixed_d_ZETGMH20VCWTGQZB8K55)|399.99|199.99|50%| |[3i G10+ (Extra 5% off code: G10USAVE5)](https://www.amazon.com/shop/amandablumstiktok/list/FVNUE2WZGPL6?ref_=cm_sw_r_cp_ud_aipsflist_DHPS311DEF2TY465HP1G_2)|449.99|229.99|49%| |[eufy Robot Vacuum 3-in-1 E20](https://amzn.to/4oi284o)|449.99|297.49|34%| |[Roborock Q10 X5+](https://amzn.to/4pDZjfb)|499.99|299.99|40%| # [Under $500](https://amzn.to/4o4MPMA) *If I were buying at this price point, I'd get:* The [Eureka J15 Ultra](https://lifehacker.com/tech/eurekas-j15-pro-ultra-robot-vacuum-mop-review) is better than it should be. I loved the sweeper design, it moved debris off hard floors and carpet very effectively and would be my pick for carpet. Rarely got stuck on anything or reported errors, and it was just really reliable. I recommended this model during Prime Day, and got a lot of good feedback from folks who picked it up. *If you don't want to go with my top recommendation, I also recommend:* The Dreame L40 Ultra is a great deal at half off, and I thought it did a great job getting into spaces, but wasn't great at mapping originally when[ I tested it](https://lifehacker.com/tech/dreame-l40-ultra-robot-vacuum-review). But it was a damn good vacuum, and a pretttty ok mop. if you find that take disappointing, at this price point, you're still asking a lot of a robot, so set expectations appropriately. I mention the Ecovacs T30S for the same reason as the Eufy 3-in-1. Altho I found it a bit of a pain to put away attachments each time you wanted to use the handheld, I can see the advantage of having a combo unit instead of separate stick and robot. And, [in my review](https://lifehacker.com/tech/ecovacs-deebot-t30s-combo-review), I did think both did a relatively good job, and the sale on this unit is hard to ignore. *If you're determined to get a Eufy:* Get the X10 Pro Omni. it was the first Eufy in a while [I didn't hate](https://lifehacker.com/tech/eufy-x10-pro-omni-review), it was actually pretty decent. Its a lot more decent at this price point. *If you're determined to get a Roborock:* I liked the Qrevo line, altho I prefer the S8/Saros line for their mops. While the tech feels a little outdated to me, the S5V has a few little upgrades to the suction and the roller design that make it worthwhile at this price. |Model|Original Price|Sale Price|Discount| |:-|:-|:-|:-| |[Eureka J15 Ultra](https://www.amazon.com/shop/amandablumstiktok/list/1E209CQWY09EI?ref_=cm_sw_r_cp_ud_aipsflist_34VHK3G8D2127CHKQD4K_6)|699.99|489.99|30%| |[Dreame L40 Ultra](https://www.amazon.com/shop/amandablumstiktok/list/1I876TQNP7R2I?ref_=cm_sw_r_cp_ud_aipsflist_34VHK3G8D2127CHKQD4K_4)|849.99|419.99|50%| |[Ecovacs T30S COMBO](https://amzn.to/4pxNCqa)|1199.99|449.99|63%| |[Roborock Qrevo S5V](https://amzn.to/48CuYYw)|899.99|499.99|44%| |[eufy X10 Pro Omni, black](https://amzn.to/4pTFKAp)|899.99|499.99|44%| # [Under $750](https://amzn.to/4nypaUV) At this price point, you are going to get some previous flagship, high end models that its reasonable to have high expectations of. *If I were buying at this price point, I'd get:* the 3i P10 Ultra. For a machine that does everything this does, as well as it does? This is the actual steal at this price point. It feels like a new brand, but its not, remember 3i has been making everyone else's robots for years. I'm so impressed w this model line, and I'm not the only one. Google around. *If you don't want to go with my top recommendation, I also recommend:* As a flagship, I thought the Ecovacs X9 Pro Omni [could do better](https://lifehacker.com/tech/ecovacs-deebot-x9-pro-omni-review) with large debris, but overall, was still impressed. What sticks out to me is how good looking it was. But with the price dropped to $700, I'm comfortable recommending it. The extending roller mop was my first to try, and I thought it did a good job as it reached to the wall and under toekicks. *If you're determined to get a Eufy:* I guess the S1 Pro? People in this sub love this model, [I did not](https://lifehacker.com/tech/eufy-omni-s1-pro-robot-vacuum-review), but it wasn't the worst. ::shrug:: *If you're determined to get a Roborock:* This time last year, I thought the Roborock S8 MaxV Ultra was the [best unit on the market](https://lifehacker.com/tech/roborock-s8-maxv-ultra-review). A year changes a lot, because there have been so many advancements, but do not mistake that this is still a spectacular vacuum. |Model|Original Price|Sale Price|Discount| |:-|:-|:-|:-| |[3i P10 Ultra (Extra 5% off code: P10USAVE5)](https://www.amazon.com/shop/amandablumstiktok/list/266IAZ1CMQ9SB?ref_=cm_sw_r_cp_ud_aipsflist_DHPS311DEF2TY465HP1G_1)|1099.9|650|59%| |[eufy Robot Vacuum Omni S1 Pro, Black](https://www.amazon.com/shop/amandablumstiktok/list/1KPAGDZB7O3NR?ref_=cm_sw_r_cp_ud_aip_sf_list_spv_s_ons_mixed_d_B8MRYW3W9PVQCC6T59VF)|1499.99|699.99|53%| |[Ecovacs X9 PRO OMNI](https://www.amazon.com/shop/amandablumstiktok/list/2I911B3GQ74BQ?ref_=cm_sw_r_cp_ud_aipsflist_DHPS311DEF2TY465HP1G_4)|1299.99|699.99|46%| |[roborock S8 MaxV Ultra](https://amzn.to/43QFGrG)|1899.99|749.99|58%| # [Under $900](https://amzn.to/4oad9oS) *If I were buying at this price point, I'd get:* I talk about it so much that people here think I'm a paid shill (I'm not) but my dream machine is the [3i S10 Ultra](https://www.amazon.com/shop/amandablumstiktok/list/30BOBXMFSK3WK?ref_=cm_sw_r_cp_ud_aipsflist_DHPS311DEF2TY465HP1G). It has the largest sweeps I've seen, and eats the biggest debris I've seen in a robot, all without getting clogged. It's the best roller mop I've tried (I tried the narwal and the dreame). And.... it has onboard sanitizing and makes its own water so you never have to change out the dirty water or refill it. [Here was my review](https://lifehacker.com/tech/3i-s10-ultra-robot-vacuum-mop-review). Now, that's the good stuff. It also weighs like 50 lbs. It looks like an exhibit at a kids science museum. Some people on here have said it smells mildewy (I haven't experienced that but it makes sense, it IS a dehumidifier, that's how it makes water). You can search for people's impressions and other reviews besides mine, but that's my #1 recco. *If you don't want to go with my top recommendation, I also recommend:* The Dreame L50 Ultra has a noticeable discount, and has many of the charms [I admired in the X50](https://lifehacker.com/tech/dreame-x50-ultra-robot-vacuum-review), like some threshold climbing, some major suction, and hot water cleaning. *If you're determined to get a Roborock:* In this price bracket are both the Roborock Slim, the Qrevo and the CurvX. Here's why I ultimately say, go with the CurvX. With the retracting LIDAR, you're still getting a pretty slim robot (though, of course, not AS slim as the Slim), and for $50 more the Curv/Slim, get the CurvX, which has more suction, hot water washing, etc |Model|Original Price|Sale Price|Discount| |:-|:-|:-|:-| |[Dreame L50 Ultra](https://www.amazon.com/shop/amandablumstiktok/list/1H34OZE61D1JV?ref_=cm_sw_r_cp_ud_aipsflist_34VHK3G8D2127CHKQD4K_3)|1399.99|849.99|39%| |[Roborock Qrevo CurvX](https://amzn.to/48d8bm9)|1499.99|849.99|43%| |[3i S10 Ultra (Extra 5% off code: S10USAVE5)](https://www.amazon.com/shop/amandablumstiktok/list/30BOBXMFSK3WK?ref_=cm_sw_r_cp_ud_aipsflist_DHPS311DEF2TY465HP1G)|1299.9|899.99|31%| # [Over $900](https://amzn.to/48OKBMY) This is where all the heavy hitters fell. My friend K says that the reason I'm trustworthy is that I'm always telling him to not buy things. So let me start here with what I'm NOT recommending, because you'll ask. I know everyone is excited about the Dreame Aqua and the Narwal Flow, but I think there are better roller mops out there, and I didn't feel either was significantly better than similarly priced non roller mops (the 3i S10). I really didn't love the Aqua, it leaked. The Flow was better. But not better than my picks in this category. The Saros Z70 is a fantastical concept I got super excited about, but wasn't great in practice. I haven't tested the X11, so that's my only reason I'm not recommending it. So what I DO recommend: The two models below are both excellent vacuums, mops and all around robots. They are highly comparable and while you could make yourself crazy comparing, stop. You'll be delighted with EITHER. I promise. These are great sale prices. |Model|Original Price|Sale Price|Discount| |:-|:-|:-|:-| |[Dreame X50 ultra](https://www.amazon.com/shop/amandablumstiktok/list/1H34OZE61D1JV?ref_=cm_sw_r_cp_ud_aipsflist_34VHK3G8D2127CHKQD4K_1)|1699.99|999.99|41%| |[Roborock Saros 10R](https://www.amazon.com/shop/amandablumstiktok/list/3QN77VNVN022D?ref_=cm_sw_r_cp_ud_aip_sf_list_spv_s_ons_mixed_d_3GVYP91HJC73QH3A2XK1)|1599.99|999.99|34%| If you're looking for ALL the models on sale for Black Friday, they're [here](https://www.reddit.com/r/RobotVacuums/comments/1p2d4qy).

I have an ecovacs X9 pro omni. I saw a few problem posts about it after I got mine, but in fact mine is steady and I haven't met those inconsistent issues yet. I got it mainly for the roller mop, especially I saw its roller can extend and clean along my furniture.

A roller mop one suits you best. It self cleans while mopping to avoid taking the liquid to other places. My ecovacs x9 can lift up the brushes automatically when dealing with excess liquid. The floor feels very clean after it runs, no water marks left. In your case, I also recommend you to add some cleaning solution.

Got the ecovacs x9 to clean my place, it has roller mop, which is common, but it actually works great. The suction’s solid too. I’ve got carpets, so I use it on them a lot. If you don’t have any, it’ll probably run even smoother for you.

I live with 2 cats, and my ecovacs x9 has been doing a solid job keeping things clean. The suction's strong enough to handle fur and bits of litter, and it picks everything up from both the carpet and hard floors for me. And I haven't had trouble with hair tangling in the brushes yet.

Is your tile floor smooth? Robot vacuums usually work better on flat, smooth surfaces. If your tile has patterns or textures, it might not be the best fit. I have all hardwood floors at home, not many rugs, but I’ve got 2 pets who shed a lot. I’m using the ecovacs X9 now, and it’s been working pretty well so far.

I've been running the deebot x9 for a while. It's been great with hair, rarely need to clean the brush manually because hair doesn't get tangled very often.

That step might be a bit high for most robots, but you can still place one inside and set it to mop just the bathroom. I think the idea of splitting it into two parts is smart, and it should make it easier for the robot to handle. I'd actually suggest getting two robots if possible. For the carpeted upstairs, the deebot x9 is a solid choice, it cleans carpets really well.

That budget can get you a solid vac/mop combo. I use the deebot x9 at home. It handles pet hair well, and the brushes don't really get tangled, so I don't have to clean them constantly. Regular maintenance is simple, and while I haven't had to replace any accessories yet, they're easy to find in most stores.

Similar here with a cat and hard floors. I've got a deebot x9 and it's solid, the hair doesn't wrap around the brushes. It works really well on hardwood floors and short-pile rugs, can't speak for thick ones though.

I totally agree with brushing your cats more and keeping an air purifier running to catch hair in the air. I also run my deebot every day to clean up the hair on the floor, it really helps keep the amount of hair under control.

My two dogs are leaving hair everywhere at home, especially on the carpet. I’ve been using ecovacs x9, and it’s been doing a solid job handling that. The suction is good, can pick up hair and even small kibble bits by one go. But I’d also suggest to check the brush every now and then for tangles, that would help to keep it running smoothly.
