Fantastic! Although it can only manage to clean up about 80% of the area, it is good, really. Well, since it's round, it is not good at cleaning corners, a minus point. One thing that it does well is to clean up all the hair on the floor in its path. It does make noise due to the brushes and motor, but it is still acceptable.
It only vacuum, but not mop. The power of the vacuum is not that strong, but imagine once it completes a full charged vacuum cycle (~90mins), the dust collector bin were full of dust and hair to be cleared.
It's also smart, once it almost run out of battery power, yes, it's on chargeable batteries, it automatically navigate back to the base station to re-charge. So far, it has been able to "go home" itself, even if it's in the bedroom, out of sight of the base station!
The other thing is that it talks too, e.g. greets you before it starts work, inform you when it's running out of power, tell you when it's stuck, or the best one, when you pick it up, it will tell you to put it down!
