- Reviewed in the United States on March 28, 2025Style: 11S MaxVerified PurchaseI have had a Roomba since the pandemic began, but it finally got tired and wouldn't suck anymore. With technology that improves with time, this eufy Robot Vacuum 115 MAX is amazing. I actually look forward to vacuuming. The remote is handy for sending it to and from its underbed home. The brush reaches further under those cabinets (and couch) that have openings too low for the vacuum to go under; it removes that visible fuzz. It is low enough to go under one cabinet that had been a problem for my old Roomba. Very quiet, so me and my cats don't mind it working around us. Takes longer and moves more slowly than my old Roomba, but very thorough. Wirecutter recommended it, the sale price was amazing, and I couldn't be happier about it.
- Reviewed in the United States on February 24, 2025Style: Omni C20Verified PurchaseLove this thing. I bought an older eufy vacuum and my wife loved it. It was nice but i was constantly cutting hair out of the roller, cleaning filters, and emptying it. Plus it would get stuck on everything it could find. This one seems more intelligent. It rarely ever gets stuck. The mop function is a plus, really gets every bit of dust up. I love the auto mapping feature. Once its done you can choose specific rooms in your house for it to clean. My son is always shutting it off when it goes in his room so its nice to be able to do the rest of the house and skip his room lol. I run it once or twice a day and i change the bag every 3 months or so. It will let you know when it needs to be done. Very easy to do. Youll want to change the water daily as the dirty water will get pretty stinky if you dont. It cleans the mop heads itself but i still clean them as needed, maybe once a month, but you could probably just do it when you change the vacuum bag. Its a little noisy, especially when its emptying itself, but its worth it for how powerful it is. Battery life isnt amazing, but it will just recharge and continue its task til its done so it hasng been an issue. I initially felt like it was a bit expensive for a robot vacuum, but after having it for a while, id definitely say its worth every penny. Cant recommend it enough!
- Reviewed in the United States on December 24, 2024Style: 11S MaxVerified PurchaseAfter reading many reviews by folks who had bought much more sophisticated models of Robo vacuums, and then found them sorely lacking in capability compared to the price, I decided to go with the low tech Eufy model. While it has a handheld infrared remote, and you can program in a set time each day where it will launch itself and meander around the house, the model is completely low tech. That said, as long as you don’t mind emptying the container and cleaning the brush on a regular basis, it actually does a surprisingly good job of cleaning a 1200 ft.² house with a combination of hardwood floors and area rugs. One of our household members produces a tremendous amount of hair. Another of our household members produces a tremendous amount of fur. We don’t have a proper entryway, hence leaves small bits of dirt and dust gets tracked into the house. The Eufy handles at all at 1/5 the cost of some of the more expensive and highly touted models. Is it sophisticated? Definitely not. Is it capable of mapping out your entire floor plan and avoiding obstacles? Nope. But if you don’t mind listening to it bumble around bumping into walls, getting stuck trying to get into the bathroom and otherwise looking completely comical, it actually does a pretty good job, and we no longer have to run the vacuum on a regular basis. It has two suction settings and we pretty much leave it on high the whole time. As others have reported the sound level is comparable to a feisty microwave or maybe an air fryer. Unless you are willing to discover all of the places where it can get itself stuck, and then block them off, you probably can’t let this thing run on its own unsupervised as it will eventually get itself stuck on a door sill or trapped underneath a couch. However, for all of its mechanical faults and lack of tech, it still manages to phone home and put itself to bed when it’s done. And I’ve seen other reviews of more sophisticated models where the owner had previously owned one of these, and they actually went back to the Eufy and junked the more expensive model. If you’re looking for the latest and greatest, don’t buy this. But if you want something that’s inexpensive (I found one for $119.00), gets the job done and is no frills. The Eufy might be for you.

5.0 out of 5 stars EXTREMELY QUIET
Style: 11S MaxVerified PurchaseUpdate, May 15, 2024: Today the new battery lasted 100 minutes.
Update, May 8, 2024: I sent an email to the manufacturer explaining the battery situation and they sent me a new battery under warranty.
Very poor manual because of very small illustrations which are not the same as on the robot, plus does not explain how to delete a setting. A fairly good robot though, cleans well but tends to remain in larger rooms, it starts in the living room of 1,500 sq.' apartment, manages to find the bedroom, but once it exits the bedroom it does not go back to finish the bedroom and washroom. My fix for this is to put it in the bedroom and close the door and let it run until it finishes the bedroom, then take it to the living room. It does not clean near the charging station. Very quiet, bumps very gently. When it is working beside you, you can still hold a conversation.
It is very easy to clean the waste bin, roller, wheels and filter. I clean it and wipe off the machine each time I use it, which is twice a month. I find this vacuum very easy to use and clean. It usually runs for about 1.5 hours, then recharges.
For $200.00 Canadian it is an okay value. It does not have the headaches and problems associated with programming using cell phones. I understand why manufacturers went that route, but it isn't good.
TIPS: do one room at a time. The reason is that the robot learns the room and wastes less time learning multiple rooms. Give it plenty of time to fully recharge between uses. CLEAN IT, CLEAN IT, CLEAN IT after each use - remember to do the wheels, they pop out so easily.

- DaveReviewed in Canada on October 14, 2024
4.0 out of 5 stars Very pleased - except for the chore of cleaning the roller.
Style: 11S MaxVerified PurchaseMy wife wanted something to make it easier to clean under the bed. We bought the 11S Max based on positive reviews and it has lived up to those reviews.
It is very basic but it does the job. No mapping of the house, no self emptying feature, no app. All we do is put it into a bedroom, close the door and let it do its thing and judging by the amount of stuff it sucks up, it does it very well.
The random motion , as opposed to straight lines, means that it might go over the same area more than once and in different directions. This gives better cleaning. When the battery gets low it will return to the base charger as long as the signal from the base is not blocked by e.g. walls.
Out of curiosity I set it going on our upper level and was impressed that it did not fall down the stairs. It gets a little way over, the sensors register that and the machine then backs up.
Emptying the collector is easy but removing fluff and hairs from the roller is a bit of a pain. The tool provided helps but even so it is not easy. We considered return the 11S for an L60 with self emptying but that only works with an app and my wife did not want to bother with that. For now. But, the thought of a more powerful machine machine that maps the whole house may eventually be too tempting to resist.

5.0 out of 5 stars Nice working machine
Style: 11S MaxVerified PurchaseJust got this. My 7 yr. old roomba finally died. This is extremely quiet. Doesn't make large smashing noises when it hits obstacles. Is working on floor and carpet perfectly. Hope it lasts as long as my old Roomba did.
- CelineReviewed in Canada on April 3, 2024
5.0 out of 5 stars Works as expected
Style: 11S MaxVerified PurchaseI got this after seeing the robot vac wars on GoCleanCo's IG highlight, this was one of the top rated vacuums at this price point. It's simple enough to set up and seems to collect dirt decently. I schedule it to do a sweep of my apartment at noon every day and it's smart enough to run on schedule and return to it's charging spot when it's low battery. You definitely need to do a proper vacuum and mop once a week, but I like the mindless maintenance that this provides for me on a daily basis.
