I bought this vacuum on 6/20/20! When I go to use it on my carpet, the brushes stop working. Started off great. So I called Shark hoping to get it replaced with a new one. Shark tells me that it's the wiring in the switch DUH! and it's NOT cover under the 5 year warranty! 
If it's the switch wiring, then it SHOULD BE UNDER THE WARRENTY!!!
I would not recommend this type of vacuum.
