WindTunnel 3 High Performance Pet Vacuum

Dyson Ball 3 or whatever they call it these days, it is by far the best bagless, the next level down would be a Hoover Windtunnel 3 or the one with the hair scrape tool on the power head. Most bagless vacuum cleaners as others have pointed out are not really going to get you to where you want to be because the pet hair will just explode like cotton candy in the dirt chamber though. The next best if one could even make such a statement would be a Shark with the hair trimmers on the power head as well.

I have 2 Hoover Windtunnels. Work great very old. I have 3 working Shark Robot vacs. Oldest is 12 yrs old. Still using all 3 on each level of house.

I would NOT recommend any of the cordless vacuums, stick or otherwise.. I spent $500 on a Dyson V11 cordless stick and it lost suction after a couple of months. Consumer Reports won't even recommend a cordless vacuum because of the power loss. I have a Hoover bagless upright that works well.
