  • nice at first
Color: Black Size: 5.73 pounds Style: 11S MAX
Edited (10/22/19) and placed on top so others can see what has occurred since making the statements below~ Shortly after returning the robovac that was not working as intended the company made contact with me (they are very serious on having happy clients). They offered me a new robovac of the same model which I told them I had already returned and received a refund for. They stated they understood this yet would still like to send my a new one which I accepted after a few exchanged emails. This company went above and beyond much the same way I run my business. I learned a long time ago if your clients are not happy you can put your company at risk of failure. Now I don't know if they just sent my out a unit with a new battery or if there have been upgrades to said unit yet I will say this new one works like a charm. The only two issues I have every had since running this for about 3 weeks is it get stuck in two areas of my home however that is not of any fault or flaw to said unit. The areas are just that kind of area; one of the areas I simple moved the two throw rugs closer together and the unit stopped getting caught in the toe kick of the cabinet, the other is under a hide-a-bed when it is in use by getting caught on the loop leg whereas the unit get in a kind of see-saw predicament (this area I will be placing tape around the leg as a bumper so it will no longer be able to breach the area. Even with these two things being of no error to their manufacturing they had a suggestion that has worked for other (I was not interested in said suggestion because it seemed a bit ackward to me) and also sent my out a new brush for all the communication I have offered (they stated it helps them to make a better unit when they know what to look for) All in all I am very please with the unit; it runs strong and does what it is intended for. Great company to work with. (original comments) As an overall cleaning unit it did a fine job for it's price. It got the bulk of the dust and what nots off the carpet and floors of our home + family room in one 90 minute pass on it maiden voyage. It amazed me how much debris where on the floors for the first few mission of capture and destroy and such become less as time went on. I had it set so that it would go on after we left for work and the house always looked vacuum when we returned. I will forewarn anyone who purchased any of these type units that you must clean the brushes daily for about the first week, after that it was about about every few days for me yet I have long hair and a cat. Also the catch bin must be emptied daily (at least that was true for me) as well as a good cleaning of the filter in the catch bin to achieve maximum cleaning power. Because I already knew this it was not an issue for me. I was off work and heard the unit start and run for about 15 or so minuted then I no longer heard it so I got up to see if it got caught (which it had done on two occasions) or just at the back of the house. Nope, it had returned to it's base to recharge which under normal use should not of happened for 90 or so minuted. I thought perhaps my cat may of pushed it off it's charger so I charged up to a full charge and set it free again. Once again it ran for a short time then returned to it's base. I know from owning many battery operated tools that this is a sure sign of a worn out battery. Instead of opening the battery compartment to check the date on the battery (some battery tools are in the warehouse for long periods of time which means you get a worn out battery to start with) I decided for a new tool that this is unacceptable and returned said item. I will be looking at other brands to see if this is an issue before purchasing another. If it was not for the battery issue and the fact that the remote only worked when I was in the same room as the unit I would of been fully satisfied with the product and kept it even though the remote was limited. Again, this may of been a battery issue as the box came with batteries for the remote as well. Nice cleaning unit providing it stays charged. ... show more

  • A watch bot never picks up that lint, but give it time!
Color: Black Size: 5.73 pounds Style: 11S MAX
This review is very similar to my 11S+ review -- I loved the 11S+ so much that I bought the 11S Max for upstairs, wanting the higher suction for use on carpet. Lots of negative reviews from people who seem to have not understood that this is a random motion robot. Keeping your expectations in line and realizing that even with a random pattern the whole house will eventually be covered at least every few days, which is way more than I ever vacuumed manually. Another source of bad reviews is the frequent comment that it is "lacking" internet connectivity. For me that's a huge bonus as I didn't want an internet connected device because many consumer grade IOT devices have very poor security. I bought two similar models, one downstairs and one upstairs. We have dark laminate flooring downstairs and it felt like even if I vacuumed regularly there'd still be stuff showing up shortly after I finished. I'd do a whole house vacuum every week, but it still felt like I couldn't keep up, so I initially bought the 11S+. I loved it so much that I bought this 11S Max for upstairs just a short time later. Since the 11S+ is so similar, I'll combine details from both in this review as they're relevant here too. For context, this is in a household with two long-haired adults, no kids, no pets. Downstairs on laminate and tile flooring with only an area rug and fairly basic furniture everything works perfectly. The initial robot got stuck once on day two in a corner where I had some chairs stacked up and gained the nickname "Waldo"... "Wall-e, the garbage collecting robot... got stuck... where is he? Where's Waldo?!", but hasn't gotten stuck anywhere since. It reliably finds its way home every day. Every day at lunchtime I come downstairs from my home office and empty the bin and I'm shocked by how much stuff is in it, wondering how I ever lived in such dirty conditions! haha My wife and I agreed that this is the best thing ever, so I bought another for upstairs, which has carpeted floors. Things are a bit different there. Nearly every single room upstairs has an obstacle that it doesn't like, and I've had to do a LOT more robot-proofing. It found its way into the walk-in closet and got tangled on a shirt that had a string fringe and got stuck. It gets up on the legs of the clothes drying rack in the bedroom and makes a LOT of noise going over them, repeatedly. It got stuck under the bed in the guest bedroom that had JUST enough clearance to get under, but not back out. In the home offices it gets hung up on desk legs. In my office it gets up on the legs of my music stand. Once it started beeping after going a bit too far over the edge of the stairs. The downstairs robot can go about its business daily w/o any problem, but the upstairs one has a problem in every single room. I'm gradually finding ways to deal with the problems room by room (such as 3d printed bumpers on the desk legs), but it has been somewhat of a challenge. Like the downstairs robot it's SHOCKING how much crap the thing picks up every day, even after a deep vacuuming with our Sebo D4. Being as this one gets stuck so often it got the nickname Dodo. I still love it, it keeps things cleaner, but does require a lot more babysitting. Over time I expect it'll get better as I continue to robot-proof to keep it away from areas where it shouldn't be. As for the long hair mentioned before: On day 1 I tested before a deep-vacuuming, with about 2 weeks of accumulation and it got REALLY tangled with hair, but I did a deep vacuuming by hand and since then it has kept up enough that hair has not been a problem at all. Pros: Very quiet, good coverage (I seldom see a missed spot), picks up a crazy amount of stuff even when you think there's nothing for it to find, cheap maintenance parts, easy setup, no apps nor wifi connectivity to phone home and potentially compromise your home network. Cons: None if your house is robot-proof, some people may have zero problems, some might have a LOT of problems. The filters for the MAX are a bit harder to find than the non MAX models. I did try to swap the dust bins between my two units and they are interchangeable. I'm not sure which filter is better than the other, but I might eventually replace the dust bin with one from an 11S so that I can use the more commonly available filters. I suspect that the filter change is part of why the MAX models have a higher suction rating as the simpler filter probably has less air-flow restriction, but I do like having the pre-filter on the other unit as it's easier to keep clean. ... show more

  • Zig zag motion cleaning, strong suction
Color: Black Size: 6.9 pounds Style: L60
I have tried numerous robot vacuums including lefant and a different model of eufy . The lefant was decent but the suction wasn’t as strong as this one, it would miss particles and constantly bang into the wall numerous times which I’m pretty sure made the vaccum malfunction over time. This version of eufy is so fast and efficient! The suction is amazing even on the lowest setting. It maps my home perfectly (2,500 sqft) and it cleans in rows which is what sold me on this particular vacuum, I despise vacuums that work in a random cleaning pattern. They usually die before they even clean what needs to be cleaned and I have 4 toddlers who leave crumbs EVERYWHERE. This vacuum picks them all up with ease ... show more
