We have two cats, and our downstairs is all tile and concrete floors. Cat hair is constantly accumulating so unless we vacuum every other day it starts to get gross. When I bought the M285D I really wasn't expecting it to do well, but I figured it was worth a shot and the price isn't bad. I was very surprised! The spinning brushes basically swipe up all the hair/debris and "feed" it into the vacuum port near the front-middle of the unit. There is an attachment included that holds a cleaning pad on the rear of the unit behind the vacuum. It comes with some pads but I've also found that 3rd party wet pads (such as Swiffer) can also be used if you trim them with scissors. This combo works great on the hard floors and it picks up pretty much everything. I was worried that the brushes would just get tangled in hair but so far that hasn't been the case. They push the hair into the vacuum pretty effectively. After a cleaning session the bin is usually full of hair and dirt that isn't on the floor anymore, and that's the whole point, right?

That being said, I haven't tried it on carpet because we have a separate vacuum cleaner for that; and I also don't think it will work very well on carpet. The instructions say to remove the brushes and cleaning pad when used on carpet, and without those all it has left is the vacuum which is centralized to a small port on the bottom and isn't very strong. It's strong enough to work effectively when the brushes are "feeding" stuff into it on the hard floors, but on its own I doubt it would do much good on carpet. So if you primarily want to use this on hard floors I highly recommend it; otherwise save some more money and get one of the more expensive units, such as the Neato XV-21.

Some technical details: The battery is NOT a cheap NiCd, it is a NiMH, which is a great feature at this price point because that is a better battery technology. The charge time is 7.5 hours and it runs for about 40 minutes, which is plenty of time to clean the livingroom/kitchen in our condo. As far as cleaning bots go, this one is pretty "dumb" in that it doesn't learn the layout of the floors and doesn't do the dirty area detection that the more advanced units do. That doesn't seem to matter much though, because it cycles through 4 separate "patterns", and this seems to be effective enough to cover an area pretty well. It even manages to follow walls decently, and works its way into and out of some pretty tight spots. It includes a dock which is nice but a little confusing to use...in spite of what the manual says, I found that flipping the switch on the robot off, pressing its butt up against the charging plates, and flipping the switch back on is the easiest way to dock it manually. Supposedly it can find its way back to the dock on its own, but I haven't seen it find it yet. Admittedly our dock placement is in a tight spot, and the manual suggests placing the dock in a relatively open area with about 2 feet clear on either side. If you do that, maybe it could work. We just flip the switch off when the battery gets low and it beeps, empty the bin, and put it back on the dock. It has 3 modes (when used with the dock): "Go now", "Go when the battery is fully charged", and "Go after 24 hours". It can also be used without the dock by plugging in the charger directly, unplugging and flipping the switch when it's time to use it. It moves along pretty well on its own but I've found that it can't traverse things over about 1.5cm high, it will get stuck halfway. It also gets hung up on door jambs on the floor and mats. So we pick up the mats and block off some spots before turning it on. It's pretty quiet, and after about 10 minutes our cats weren't scared to be around it.

Overall I'm pretty happy with this purchase. It saves us a lot of constant manual vacuuming and I think it's a good value. If you primarily want a bot to use on hard floors and don't want to spend a lot, I recommend this one. Otherwise save up and get one of the more expensive units.
