I work in an understaffed animal shelter so we really dont have as much time as I'd like to sweep and mop all the concrete floors in our building. So I figured I'd give a cheaper robot vacuum a shot to see how viable it would be in our building. Its not a massive building but it does have lots of long hallways that I figured would be pretty easy for this little bot to handle since it wouldnt have a lot of obstacles to avoid.I've been messing with this robot for about 4 days and here are my honest thoughts on it. Feature by Feature.The Smart Cleaning modeThis is the only mode that creates a live floor map as it cleans, mostly relying on bumping into walls to figure out the floorplan. As opposed to some other robots that use LiDAR scanners to map out rooms and save the data for future use. This guy does not do that unfortunately, which I knew purchasing but like I said wanted to try a cheaper option first.The map it generates as its bumping into walls can often be skewed like in my included picture. I can assure you the hallways in my building are all 90 degree straight angles. Whereas in the picture the hallways are curved and tilted in odd ways. Which led to it having inaccurate information once it tried to go back to unfinished areas creating a hard wall in the middle of an already mapped hallway which led to it getting stuck going back and fourth along the top wall as you can see in the picture because it thought it was going into a corner with no way through. It did not do it quite as bad the second time I ran it so im not sure if it was just a fluke. but its clear it does have a hard time accurately mapping long hallways straight. when closed off in a mostly square room it did perfectly fine mapping the room. It also does not save these maps for future use so it already knows the layout, instead creating a new map every time it is ran in smart clean mode.Edge ModeThis was the most effective mode for my use case. The shelter obviously has a lot of dog hair which collects where the walls meet the floor. This robot managed to do the entire building only getting stuck once on a section of carpet but I also had the mop attachment still on which I think created too much friction with the carpet causing it to just kinda do circles on the carpet.Spot CleanKinda useless if it was doing it right. I set it in the middle of a large room and told it to spot clean. Which it demonstrates as just doing a spiral outward. Now I expected it to just keep spiraling outward until it hit a wall or something but it just did like a 5 foot diameter circle and stopped. I did this multiple times thinking something just messed up and interrupted it but I think that's just all it does..The App.The App isnt the greatest. Its simple and gets the job done but it lacks any real details about all the various settings and modes. There is no description on the differences between "Smart Clean" and "Auto Mode" or what the "Carpet feature" does. The paper manual included has slightly more information about these but its still pretty vague.The VacuumProbably the best thing I can say about this vacuum is it does vacuum very well. with the dual corner brushes on the front it grabs all the hair and little bits feeding it right into the roller brush underneath. and it has great suction really packing that small dust bin tight.The MopNot great. Kinda regret getting this version with the mop attachment. It kinda just drags any dirt and grime behind in a wet little snail trail drying into visible streaks. It also doesnt soak the mop pad very well mostly just getting the left and right side of the pad leaving a mostly dry middle and this is with the water use set to "strong" You can remove the mop attachment and just use it as a vacuum but the dust bin and water tank are one piece so you have to empty the water tank which often leads to water getting into the dust bin which you dont want so I ended up having to wipe water out of that and let it fully dry before being able to run it again. I cant really see a good use case for this type of "mop" because its just not going to clean well dragging a wet dirty rag behind it. The instructions also tell you not to use any disinfectant additive to avoid corrosion so its pretty pointless for disinfecting floors.SummaryIve only got experience with a couple of these robot vacuums and I think in the right space you could get your moneys worth here. I mean it is a pretty cheap price for a 2 in 1 robot vacuum with app control so you get what you pay for as with most things. I would say the killer here is just how useless the mop is which would be fine if the water tank didnt take away so much space from the dust bin. I have ordered the WYZE Robot Vacuum which is 50 more dollars than the 150 I paid for this one and seems to have a much more robust navigation system with LiDAR and many more smart features in the app. So hopefully that one is more useful for my specific use case.
