The vacuum aspect works very well, and the device doesn't bang into objects or walls. It does not seem to navigate back to the charging station. Sometimes the machine goes back to the same spot in the room while missing others, but overall I like the performance. It has no problem going under furniture or going over small raised borders to get to other rooms.
Did not work out of the box. Takes 10+ min to sometimes find it's charger. Doesn't actually move when in any cleaning mode, and battery dock says "fully charged" when it is not charged at all.
Do not waste your $$ on this product.
The vacuum did not work even after the 2 hour initial charge required according to the instructions. The voice activated vacuum stated the "charge is complete" then slightly slid off charger but would not do anything else. I am returning it.
We got a Disc error when inserting the CD instructions, so things started badly. The disc never worked. The vacuum does not pick up all the stuff on the floor, so I have to go back and sweep after the unit is done.
I haven't tried the mop function yet, hopefully it is better. So far, not worth the money.
