All in all for the price its a pretty solid mid level vacuum. I'd go as far as to say that it rivals other brands with a similar price range and more features. I've had vacuums that boast about having 4k PA suction power and let me tell ya, at 4k PA those things were loud. The eufy c20 at 7k is practically quiet compared to others with lower PA. Even on its highest suction its still quiet compared to leading robot vacuums and others.
One issue that id like to note is that the vacuum doesn't hit all of the spots on the floor sometimes. There will be an open space and for w.e reason the vacuum thinks there's something there. I tried cleaning the sensors to see if this would fix the problem but at the moment it's not a big issue.
I wonder how the c28 is going to compete with this budget friendly vacuum.
Wirecutter, the NYT version of Consumer Reports, recommends this as the runner-up to its fancy first choice robot vac. The day I read the vacuum article, this mighty little machine was half off. How could I say no?
I use it as a daily supplement to my 1x/week major vacuuming with my canister. I have a mixed breed dog who has lab, golden retriever, and husky in her DNA. Her hair is short like a Boxer, and she sheds year-round, but in the spring and fall, she loses her entire undercoat. Hair is everywhere. I don’t have time to vacuum every day so I bought this vac
No regrets.
Cons:
I live in a 950 sq ft 2 bed/ 2 bath condo. I don’t have an ideal place to park it so that is a problem. As a result, it cannot find its way back to home base. I must assist.
Eufy, the manufacturer says it runs 100 minutes on a single charge. Not true. I am lucky if I get an hour, which covers one room thoroughly. No matter, I run it 3x a day. Charging takes a couple of hours.
It gets stuck under my couch so I have to block that space off.
The mapping feature isn’t great and I don’t think the coverage is great because it zigs and zags. However, for me, it’s better than not vacuuming.
The side broom thingee will not stay attached.
It does not like flimsy bathroom rugs. I must move mine before it embarks on its journey.
Pros:
The price!
It picks up the really fine hair from my dog’s undercoat, which is why I bought it.
It’s not noisy like my canister vacuum.
It’s easy to use with the remote.
The refuse drawer and beater are easy to remove and clean. I use my canister vac to clean the refuse box, filer, and beater is effective and easy.
It’s highly entertaining to watch my dog interact with the robot. She is a 50lb wimp! I think I like that the most.
Overall, it serves my purpose and I am happy with it. I took 1 start off for the cons.
It was a peaceful Tuesday morning. Birds chirping, coffee brewing, my adorable little maltipoo princess just did her morning zoomies and—as I would soon learn—left a stealthy little gift on the tile floor in the downstairs bathroom. I didn’t see it. But Eufy did. Oh, Eufy saw it all.
And instead of calling for help… she went straight into it.
I came back 30 minutes later to what can only be described as a crime scene. Eufy was proudly parked in the hallway, looking like she just saved the world. But no, she didn’t clean anything. She decorated.
There was poop Picasso all over the tile. She must’ve done laps, smearing it like a toddler with chocolate pudding and no supervision. Skid marks down the hall. Poop trails around the baseboards. She even managed to fling some under the cabinet. That’s talent.
And the wheels—my God—the wheels. Caked. Textured. Possibly haunted.
Cleaning her was like detailing a war-torn Roomba from the trenches of a chocolate battlefield. I had to pop every part off, scrub with gloves, bleach my soul, and apologize to my house.
That said… before the bathroom incident, she was amazing. Quiet, efficient, and kept the floors spotless. But if you’ve got pets, please understand: this robot has no poop-detection algorithm. None. Zero.
Would I recommend her? Absolutely—just not as a bathroom explorer.
5 stars for performance.
Minus a whole galaxy for turning tile into a Jackson Poopllock painting.
Still love you, Eufy. Just… next time, maybe don’t freestyle in the bathroom.
Also, she bumps gently into my furniture and painted baseboards. I tried another brand that hit things quite hard.
The only cons I can see are you need to use the remote to change up her settings. Additionally I did take out an extended warranty.
If you are looking for all the bells and whistles, this one is not for you. But, for the price you can't go wrong. I will update my review as time goes on.
What it does pretty well is vacuum rugs, carpet and hard floors. Unlike many robots that only have rotating edge brushes and vacuum, this model has a rotating brush on the bottom that helps with rugs and carpets. I ran it daily for a week and it was still picking up dirt that my professional house cleaner was not getting previously.
It is also a little thinner than others I run allowing it to get under more furniture.
The full charge run time is over an hour on turbo mode. It avoids stair drops and has never failed returning to dock. It does however occasionally get stuck and can’t get back.
What disappoints me a little is that it only has one rotating edge brushes instead of two. This means that in edge cleaning, whether commanded by the remote or its own algorithm, it can only edge cleaning in a counterclockwise path. The other nit is that scheduling through the remote is daily at one time, no skipping days or twice a week for example. Pretty crude IMO. I don’t use the remote, opting for a manual start whenever the mood strikes.
But when it doesn't work it is very frustrating. Somehow despite all the advancements in robot vacuums, these things still cannot deal with cables. Had it for a week and essentially any time it is cleaning a room that is not the kitchen or bathroom, he will get stuck in a cord. Also these things still do not know how to deal with hair. The bristles are going to just get tangled to the point that you have to bring out scissors to free it. Stuff like that is really annoying and removes from the good about it. Also spent 20 minutes trying to understand why it kept saying the water tank was abnormal, and I had to find a little sewage tray and clean that out.
When it is able to clean, it does a great job. Works well on different surface types. The app is pretty good and pretty easy to set up. It's nice to be able to just run different levels of cleaning on specific rooms. Definitely could be better, especially when you're considering the price of this thing. A lot of cool tech here with a few annoying things that should really be ironed out by now.
Pro – quieter than our previous Roomba. Low profile lets it get under couches and chairs without getting stuck. Decent suction. Handles dust like dirt very well. The included multitool (brush/comb/blade) is very useful and convenient for cleaning out the hair, stings and stands, and thick dust/debris that accumulates in and around the sweeping brush. Decent run time between charges.
Con – the sleek shiny black surfaces are fingerprint magnets. Straight sweep brush not the width of the vacuum; only 5 1/2 inches wide. Sweep pattern odd. Rather than an incremental direction change allowing for a logical coverage of the floor it redirects to a completely different direction. If confined to one room it would eventually cover the whole room, but if there is a door or passageway to another room it could very easily end up there from one of its redirects. Not the best at sucking up grit dirt. Drops grit when you pick it up as there is a strong tendency for that grit to stay with and around the sweeper brush rather than being sucked into the dirt receptacle. Struggles with going over cords. Documentation is mediocre at best. Some icons on the vacuum and remote do not match those in the documentation.
**Removing the dust collector filters is totally unintuitive. The filter enclosure has been totally redesigned and appears almost sealed into the dust collector. The filters won’t release with regular poking and prodding and the manual shows an image of it being pulled out from the top with two fingers. (NOT TRUE). To get the filter out you need a flat head screwdriver to pry/torque it out. There is a well with an embossed triangle at the bottom that gives you access to the side of the filter. Insert a large flat head screwdriver in the center and at the top of the exposed filter side. Push in while prying upward and torquing the screwdriver head. This will release the hook tab holding the filter down and the filter will release. When putting the filter back in it is easiest to use the screwdriver to push in to the hooked tab as you slide the filter back down so that tooth more easily clears the dust collector frame.**
This review has been updated, as I learn more about the product. The number of stars has been adjusted from 3 stars up to 4 stars.
If you leave stuff on your floor, don't buy this robot vacuum. The 11s's navigation AI is very good, but if you leave a pile of clothes in a corner, it will get stuck on a sock. The 11s's corner brushes are very good at sweeping up dust and hair, but if your shoelaces aren't tucked inside your shoe, it will wrap them around its brushes. You cannot push all the clutter off to one side, as unlike many robot vacuums, the 11s does not come with any kind of "invisible barrier" tools. This can actually be a point in the 11s's favor, though! Having this robot vacuum encourages you to clean up after yourself every day. If you have kids that leave toys out, you can't elevate your computer cables off the floor, or you know that you won't care enough to keep your floor un-cluttered, then the 11s isn't for you.
The number one situation where you would want the eufy is in a dorm or small apartment. It's a huge space saver and a huge time saver. The vacuum arrives in a carry handle equipped box that is barely larger than the device itself, so it's laughably easy to travel to college with. The dust bin can be emptied while the robot stays on the charging pad, so you only have to pick it up once a week. The entire device really is quieter than a microwave at maximum power, so you won't annoy anyone else on your floor. In a more traditional, multi-story home, the 11s shares the issues of many robot vacuums: it's much harder to keep the entire floor clear of clutter every single day, and it won't work if anyone leaves anything small on the ground. Obviously the robot cannot climb or clean stairs, which makes the automatic scheduling feature utterly pointless outside of a single-floor building. Most area rugs and very high quality carpets (anything half an inch or deeper) will be too much for this machine's wheels, and you'll have to invest in an upright.
UPDATE ON THE HIGH PITCHED SOUND: In my original review, I complained that the eufy 11s makes a high pitched shriek while vacuuming. This is true, but isn't nearly as much of a deal breaker as I thought. First of all, I've gotten much more used to it. Obviously, that's a personal preference thing, but if high pitched sounds really bug you, this can still be the machine for you! The squeal is only audible in "low power mode", and goes away in max power mode. The robovac automatically uses low power on hardwood floors and high power on carpet, but if you manually select high power on a hardwood floor, the high pitched sound goes away. Although it wastes battery power, people who are bothered by the high pitched sound can force the robot into max fan speed mode when they're at home, and allow it to choose between low power and max power while they're out of the house.
I give it 4 stars because the marketing and description list it as a product for any kind of home, while I see it as a product that works best in smaller, single floor situations due to the lack of barrier making tools.
This second half is aimed more at eufy than at a potential consumer, but reading it might offer you more insight on how this product works.
Dear Eufy:
On the day I purchased this product, I noticed a potential point of failure: the plastic that secures the brush roll cover is exceedingly thin, and appears to be an intentional point of failure. The clip is supposed to bend and fit into the hole on the robot, the frame of the hole itself does not need to bend at all. The problem I have is that the most likely breaking point is on the robot itself instead of the easy to remove and replace underbelly cover.
The Robovac's AI is clearly capable of detecting and avoiding "virtual walls", and the bot can be manually redirected with the remote control. Although it may be impossible with the current product generation, future products should include virtual walls. They could be sold separately, they wouldn't have to be battery hogs if you promote the use of rechargeable AA batteries, and as older Roombas have demonstrated, they allow a "random" navigation bot to know which room of a house it is cleaning.
Speaking of virtual walls, the barrier around the dock is way too big! There will undoubtedly be a large ring of dust in the area that the dock is located in my room. The robovac only needs to avoid the thin strip of ground near the wall, where the dock's cable would be, not a big semicircle section of my room.
Having a controller is great; it puts many of the moving parts on a cheap component, not the expensive component. That's just the theory, though, because the remote isn't sold on Amazon! What will I have to do if I'm outside the warranty period?
Finally, I'd like to say two things about the controls. First, I'd like to see a few buttons and lights added to the bot itself. An orange "brush clean"/"filter change" reminder light (solid for weekly clean, flashing for filter replacement), and a green "schedule set" light (solid for "schedule set, flashing for "scheduled clean active"). The orange light could go to the left of the power button, while the green light would get situated to the right of the power button. I'm already certain that I'll forget to clean out the roller brush and replace the filters when the time comes.
Finally part two: please, PLEASE make the "start|stop" be "pause|resume" instead. If I'm 2-3rds through an edge cleaning session and something gets tangled in the side brushes, I'll press stop to freeze the bot, but pessing start won't resume the edge cleaning session, it will begin a brand new auto clean.
That's all I wanted to say about this. I don't know much about its capabilities or reliability as this is my first day owning the product, but I must admit I'm hopeful.
The Eufy has two brushes on either side, whereas my Roomba has only one. I find that the Eufy appears to clean the general floor area, and then go back for edges, and the two side brushes help with this. Both are a little “stupid.” I try not to watch them do their job as I consistently want to interfere and nudge them where I see actual dirt/particles on the floor. Both will go seemingly all around dirt, retreading spots they’ve already been (and wasting battery life in the process) rather than moving along any real sensible path. However, I have also noticed that the Eufy seems to go along straighter paths/lines than the Roomba. However, both are supposed to return to their bases when the job is complete. The Eufy has found its way back to its base one time as far as I can determine. The Roomba finds its way back about 1/2 of the time. The Eufy will continue to run if picked up, the Roomba shuts itself down immediately.
The Eufy is slimmer than the Roomba. I find that the Eufy tends to get stuck less frequently than the Roomba. For example, it can go under my coffee table that sits close to the floor, whereas the Roomba would get it’s front stuck under the coffee table and signal for help. The Eufy has gotten itself stuck about twice since I’ve had it, and each time it is under the chairs at my dining room table… it is a little wide and has gotten stuck between the legs. The Roomba frequently gets itself into jams, and only seems to turn left when trying to get out of them…
In terms of navigation, both do their jobs in an almost haphazard fashion. I would like to see them have an actual “dirt sensor” that would lead them toward areas with noticeable particles. The Roomba does have some sort of sensor as when it finds an especially dirty area it will swirl around it several times. The Eufy apparently has a mode where it applies extra suction, but I’m unsure if it automatically switches to this or if it has to be manually set to do so.
The Roomba DOES NOT LIKE BLACK RUGS or heavy pile rugs. I have two rugs that are edged in black, and the Roomba senses a barrier and either will not go onto the rug or will get stuck shortly after moving onto it. I also have a medium pile rug with some black squares on it and the Roomba dies out on the rug every single time. The Eufy navigates these FAR BETTER… both the medium pile rug as well as rugs lined in black or having black squares.
The Roomba bangs into furniture and other items sometimes quite violently. I have a very heavy antique mirror that the Roomba banged into and it came crashing to the floor. I also have some large candles on either side of the fireplace that the Roomba knocked around like crazy every day. The Eufy seems to notice edges better and will actually stop itself when it comes close to an object and move around it without hitting it, or, if it does go toward it, it is far more gentle. However, this sensor also can impede its capacity to go under objects like couches. The Roomba alway went under my couch, whereas I don’t think the Eufy has ever been under it as it appears to sense it as a barrier and goes along the front of it only.
While both say they have edge sensors, neither the Roomba nor the Eufy seem to be able to navigate edges to stairs very well at all. While neither have actually flung themselves over, they both get stuck at the edge with a wheel or two over and have to be saved. So some barrier is necessary to prevent them from falling over the edges of stairs.
The Eufy to be FAR quieter than than the Roomba. Sometimes when it is running I can’t even hear it.
The Eufy I have has a remote and is not connected to WiFi. But, apparently, there is a newer (and a little more expensive version) that can be so connected. The Roomba connects to WiFi and I can control it from my phone, and it also sends me alerts (when a job is done, it is stuck, etc.)
Both the Eufy and the Roomba are programmable. I have them set to vacuum daily at 9:00 a.m. I set the Eufy from the remote and the Roomba from its app on my iPhone. The Roomba is definitely easier to program as I have to refer to the guide to know what I’m doing on Eufy’s remote… and then I’m still not sure I have it down correctly.
The Eufy seems to go for about an hour or less and then dies out with its light orange. The Roomba appears to have a longer battery life after each charge. The Eufy has a higher suction setting that apparently can drain the battery power in 30 minutes or less. It is frustrating to see both vacuums going over the same spots continuously or routes knowing they are wasting battery life doing so. I think both could be “smarter” with greater debris detection or something. Again, I think the Eufy tends to follow a straight path just a smidge better than the Roomba, but not by much.
You will want to make sure that power cords, and other such things are moved/protected from the vacuums. The Eufy, because of both brushes, gets caught up in power cords, speaker wire, etc. far more easily than the Roomba. But the Eufy comes with cord ties to tuck them away. You could just as easily use bread ties for power cords. I also have pets (three cats) and they have all sorts of toys. The smaller ones I try to keep out of the path of the vacuums.
Speaking of pets, both vacuums appear to be doing well with keeping my rugs free of pet hair. I would suggest that if your pets make a mess (hairballs or accidentally going to the bathroom) that you clean this up immediately. I can only imagine the horror that would result from either of these vacuums going over those messes and how they would be drug over your entire house!
Speaking of pets… my cats seem quite enamored with the vacuums and will stalk them as they go through the house. They do not appear to be afraid of them, and sometimes will sit and have them bump into them and lazily move out of the vacuums path. This is strange as one of my cats literally will run and hide if she sees me even getting the manual vacuum cleaner out to use. However, all pets are different. So, I’d introduce the vacuum and the pet as nicely as you can.
Both the Eufy and the Roomba are very easy to clean/empty. I empty the dirt bins daily on them.
In terms of suction, I’m not sure either of these do as well as my manual Dyson. And both the Roomba and the Eufy sometimes don’t pick up debris that would easily be handled by a conventional vacuum cleaner. However, I repeat that I have not manually had to vacuum my house since Christmas. Not once. I have thought it might be a good idea to do that about once a month though and let the robotic vacuums deal with the floors in-between. The dual brushes may help the Eufy collect debris a little better… and it definitely appears to have better edge cleaning than the Roomba. But both seem to do the job to my satisfaction overall.
I like that the Roomba actually talks to me to tell me what the problem is (a job is done, it is stuck, it needs recharging). Whereas the Eufy has beeps (one, two, and three). I don’t always hear the beeping or exactly know what they mean without referring to the guide.
I like both the Roomba and the Eufy. They each have their strong points and weak points. Either way, not having to manually vacuum every day is a godsend to me, and makes having pets a little less cumbersome to clean up after. If I had to choose, I’d probably go with the Eufy due to its quietness of use, better edge detection and cleaning, dual brushes, tendency to vacuum in a more directed fashion, and slimmer size coupled with less fierce bumping into objects.
Hope my review was helpful.
