We already have the Shark version which is amazing. This one isn't that pleasant. It's not super smart. Not so good at navigating space. It just has a curvy thing that smacks the crumbs toward the suction cup. Most of them have 2. It's pretty good, but not as good as the stronger brand. The app is not very good. But it works. It makes cleaning our basement easier than we do. This is a fraction of the cost of more popular branded versions. Overall not bad for the price, but not surprising either. If you don't want to spend money on a well-known brand, this only works at 4-star level, not 5-star level.
