i got this a little bit ago because I was at my brothers house 1 day and he had it running and liked it. I leave in a 1 floor house and got this product so when no one is home we press the button and the vacuum just goes on its own and cleans and picks up crumbs all day long. the quality  performance and all is defiantly worth the value. it sucks up crumbs and dirty and is leaving my house much cleaner. this is a product everyone should have in there house. I cant believe i didnt get one till now.
