As another reviewer said, if you're on the fence about spending this much money on a vacuum - just do it! I absolutely love this vacuum. I wanted to replace my $300, one year old, Hoover Bagless Windtunnel canister because I was tired of knocking the plaster off the corners of the walls when dragging the thing through the house! I just doesn't take corners well. I hated that vacuum! I received this vacuum and immediately put it together. The manueverability, ease of use and suction of this product is outstanding. I couldn't be more pleased. The dirt canister holds quite a bit, too. I love being able to push a button and have all the dirt fall right into the trash can. One minor problem I encountered was that the vacuum was missing the clip for holding the crevice tool to the vacuum. When I called Dyson to register my vacuum, they immediately sent the replacement part free of charge. The amount of money I saved on this refurb far outweighed having to make a phone call for a free replacement part.
