I have a Dyson Animal and after 6 months it started to cut off a lot when using the power head. After reviewing all the comments I decided to check it for myself. We use it mostly for carpet cleaning and on the power head I noticed it needed some cushion so it won't drag on the carpet. After placing some cushion it works great again. I would use velcro type cushion that I cut into strip and stick it on the power head that touches the carpet. Hope this helps others.
