I have tried every avenue to get assistance with my Dyson animal ball 2. The vacuum does NOT push or pull on my floor to the point that I can't use it. I have chatted, sent emails, and called customer support and can't get anyone to help me. This is a known issue in the Dyson community and on line. Apparently this is caused by an air flow issue. I am frustrated at the cost of an appliance that does not work. Thoughts?
