Hello... I own an up rite Dyson. The problem I am having is the wheel will stop turning when I am vacuuming the carpet so I will have to push down on the button that switches it over to vacuum hardwood floors, It will spin for a little while but then quit... so other words the wheel keeps stopping and it acts like I'm vacuuming a hardwood floor... I have already cleaned the filter and emptied the cartridge. Can you tell me why it is doing this and how it can be fixed? Thank you, Bonnie
