How well does this work on carpeted stairs?
Do you need to use the tools or is it possible to use the main machine? How satisfied are you with the cleaning of the tools?
You have to use the tools. I used them and it took some experience, but they did work. Stairs just aren't easy. It would be risky to use the Hoover on stairs without the tools. I strongly discourage this. A plus is that the tube connecting to the tools is long, giving a lot of range. We have 14 stairs and I cleaned all of them with the Hoover unit at the bottom of the stairs. It is a challenge to get the unit up and down stairs when you have two levels to clean....From my research, this is a common problem as the cleaners need a certain amount of features to clean, which adds to weight, etc. There are some cleaners for smaller areas, including stairs, and results are mixed.
