This is the AeroCatTower, a combination cat seat and… air purifier, like observed from CNET sister site Mashable. Call this thing what it is: a passive cat groomer. It doesn't want to remove cat hair from the air – it goes straight to the source! Your cat sits on the tower and the fan gently blows the fur away from the body.
The tower has a sensor, which detects the weight of a pet, turns off the overhead fan and sends its findings directly to the seat. They want to know about our tough cats!
I know cats are weird, but my cat doesn't like things that hum and hum. He wouldn't go near this thing.
