i love this braava. i hate mopping/cleaning hardwood floors. this does it for me and is easy to operate. just set on floor and walk away...braava will mop for you. saw some comments about it stopping after mopping for half the time allotted (approx 2-1/2 hrs charge). this also happened to me. however, discovered that if your area is small (mine is approx 200 sf), the GPS measures your area and when braava has cleaned the area measured by GPS, it stops because it is done. so....there's nothing wrong with your braava. i use it about 2 x per week. my floor is now forever clean. love, love it. also, the service department is very helpful, efficient and friendly. (thank you Ariel) this is by far, one of the most wonderful machines i've bought. thinking now of getting the carpet sweeper one....i think i'm spoiling myself.
