A:AnswerThis model has one rotating side brush. The major brush is the center rotating brush under the unit. I have seen models with 2 rotating brushes, but have no complaints from this model. (Note: my box came with 2 side brushes so that there is a replacement if/when needed.)
A:AnswerI don't see why. You can detach the dust bin from the vacuum, empty/clean it & then reinsert. The dust bag in the station is then not touched at all.
