The best robot I’ve ever used and seen! I’ve had 3 other similar robots of high quality but never a Shark. Hands down the cream of the crop. VERY easy to setup. The app is dummy proof to use. My wife’s favorite part is it’s not rough on the furniture bumping hard into everything like our previous units. Makes cleaning and dispensing the dirt and cat hat after super easy. Almost no mess anywhere. Can’t rave enough about it.
