Review (5/5): This is easy to use and great.
It is a great product and works. You just can not push too hard because the rotation stops. I mean think about it, it runs on batteries, so it only has so much power. So you just have to let the tool do the work and it takes a little longer, but it is really easy to use and makes it easy to pick up by the sofa and run it and put it down.
Hopefully after a while, you wont have to use it as often.
