Very powerful, worked very well even as the canister was completely filled. It was a nice, welcome change compared to our aging battery-powered vacuum. It picked up so much dirt, dust, and hair that our old vacuum had left behind. Pros: --Powerful, no battery issues because it's a plug in. --Floor brush did not get clogged or covered in hair/string/fibers. --Floor brush light is pretty good. --Canister is easy to empty. --Canister volume seems good. --Pretty long cord, did entire 2nd floor without moving plug in location. Cons: --Heavy. --Crevice tool is pretty thick at the end because of the brush slider. It's also quite short. About 6 inches longer would help a lot, mainly for getting into tight spaces. --The vacuum is a bit too thick/tall, can't vacuum under bed or dressers. Overall I'd recommend it and it's a welcome improvement over our current vacuum.
