I have always bought cheap vacuums until I decided to try this one. We couldn't be happier. It is very powerful. We use it on the wood floor, linoleum, and carpet. The time it stays charged is more than enough to vacuum everything, One of the better purchases I have made. Compared to the s21 which Samsung seems to have no desire to fix the problem. Just send back for repair over and over. Vacuum I am very happy with. If that's what anyone is wanting to know. My days doing business with Samsung are however over.
