Chosen Solution
I have a Shark Pet Pro-Liftaway, Model NV752. I recently changed all the filters, cleaned everything up, dried the filters thoroughly, and reinstalled. But only the top of the dust cup fills up; not the bottom. With 2 ragdoll cats and lots of wall-to wall carpet, I need to get this fixed. Help!!
Hello! I recently started having the same problem as you and also after cleaning the filters. Have you found a solution?
I wish I could help you but this is also happening to me and I have a golden retriever. It’s very frustrating.
