I too have the Dyson animal ball. Power head for carpets, etc. Unreal performance. You do have to make sure all connections are good and sealed. Any seal that gets damaged or rolled when dumping the can, will have to be replaced. And it does have a filter that one should keep an extra on hand. Other than that, for me, an old single guy that really dont care much for continuous vacuuming with a low power unit, the Dyson is an easy investment to make. I bought mine on a sale at Costco. $400.00 here about a year ago. Partial assembly required.
