"this is light years better. More suction, and spinning mopheads get the floor waayyyy cleaner ... The filthy water coming out of the dirty tank makes it clear it's mopping well!"
"I also have two giant long haired (nonshedding excessively) cats. I shed hair a LOT. Worse than the cats. It works so well."
"it is legit the cleanest my floors have ever been - I'm running it daily and don't need to do it manually at all any more. ... I truly find it squeaky clean and way, way better than my manual mopping that happened less often."

"Best roller brush we've ever had, and they are usually awful for us because of hair tangles (2x long haired dogs snd long haired people). ... The comb works well to get all/most of it loosened and the rest can be easily pulled out with fingers. ... Best part, the ends of the brush just pop off so anything wrapped around the ends can just be pulled out without effort."

"the comb keeps the roller way cleaner. ... Cleaning comb works GREAT on our dog's long hair"

"for the sale price of $399 usd it is the active-mopping vac robot I always wanted but could never afford."
"active mop/base tank features trickled down to a price I could justify and I am sooo happy with it!"
"The c20 is pretty much the answer to all I have ever wanted in a robot within my budget (regularly goes on sale for $399). ... I'm very, very happy with mine for the price!"

"I find it plenty user friendly - took me a minute or two to figure out how to use the scenarios and use the map editor, but no problems as such. The scenarios are a great feature for flexibility, as then you can schedule those specific settings to run whenever you want, or even just click them to start it manually when needed. For instance, I have one lowest suction for quiet times, one that double mops just the kitchen etc, and then I have set those up for on specific days times etc."
"Mapping has been excellent and it has adjusted to changes well (eg if a chair gets moved)."
"Maps very well using some version of laser tech and improves the map as it is used."

"Get one with the emptying station and you can leave it untouched for months."
"a self-empty base with a bag ... I hate vacuums that don't have bags, because every time I'd dump the dust bin in the trash, I'd get a faceful of dust ðŸ˜"
"the auto-empty bin is actually way less annoying than I expected lol"

"It ran me over and also bumps my dog all the time ."
"it had terrible object avoidance and took some of my lighter furniture for a ride."
"Obstacle avoidance is not the best, so cables or smaller things can get stuck in the brush. ... it will go through cables and small socks unfortunately."

"It would travel five feet, and then do an entire spin, or two, then go another five feet and do it again. ... And this was after creating the map and already having cleaned a few times. It's like it never learned and always forgot where it was."
"But right out of the box, I have a glitch where it keepa mopping my rugs and it ignores any no-mop zones I put on the map."
"I can’t believe how clunky it is. ... I had to babysit the thing like a toddler with a death wish."

"I can’t stand the eufy app though. ... It has been glitchy for me."
"It's compatible with alexa/Google voice but I haven't been able to pair it yet. It's glitch so far."
"Map customisation is not perfect. ... The app considers 2 rooms and a corridor one room and I can't edit it."

"Battery would die after 45 minutes of cleaning, on STANDARD suction."
"Vacuuming is also good, but on max power the battery will run dry in about 20 minutes. ... Upstairs is fully floor carpet, and it can cover like 20-25m2."
