Reviewed in the United States on June 9, 2018
My last vacuum robot was an older generation Neato, and it showing its age badly. We have dark, hardwood floors covered in rugs, some carpeted rooms with attached tiled bathrooms, in a multi-level house. So the notion of getting a mop/vacuum all-in-one was pretty exciting, hence: the Ozmo 930 purchase. After a few days of using it, my excitement has waned a lot. I'm on the fence about returning it after a number of issues and less-than-clear descriptions of how it works.
First, the pros: the vacuum and mop actually work well. The bot is quiet and fast (compared to our Neato) -- you can definitely watch TV while its running in the same room as you. Vacuum picked up a lot of hair (we had a dog visiting this week, so good time to try it out). The mop, especially if you increase the water flow to high or max, makes your floor nice and shiny again.
Ok, the cons. There are a lot.
First, one thing I wanted to clarify since this was completely unclear in the description and the reviews, is that as far as I can tell the bot works in two modes: mopping OR vacuuming (not both). The way it appeared to be described is that it mops when its on hardwood, and vacuums when it is on the carpet. This is not the case at all. You have to physically attach the mop panel to the bot to get it to mop, but by doing so it disables vacuuming completely. This greatly diminishes its "automated" portion, since you have to physically modify the bot each time you want to switch modes.
This issue propagates into a second issue. Given the bot won't go over carpet when it is in mop mode, that means if you have a hardwood floor that is "cutoff" from the hardwood floor the bot charger is on (e.g. an attached tiled bathroom to a carpeted bedroom, with the bot charging outside of the bedroom), the bot will NOT MOP IT. If you have a rug in a hardwood floor, its easy for the bot to get "cutoff" from portions of the surrounding hardwood and never mop these.
Third, the robot cannot be moved. First, there's the "map bug" which I suspect will get fixed, but for now means if you life the robot up for any reason, it loses the map of the house -- the robot will NOT mop again until it re-maps the house. BUT, to attach/detach that mopping plate, you often have to physically lift up the robot. See the issue? The more serious issue is that you can't really move the robot to other areas of your house and simply start mopping, without first having it do a full vacuum/map first. We have a small raised landing that it would be great to drop the robot on, start it in mop mode, let it clean, and then replace it on its charger, but it doesn't allow it.
Finally, the app is REALLY moody -- you may get login errors preventing you from connecting to the robot.
Some of these things are likely fixable with a firmware update, but I don't know the company well enough to assume they will update it in a timely manner. I suspect the one-at-a-time mop/vacuum mode is physical, and not fixable.
We're on the fence re: returning it.
