I got a EuroPro bagless stick Shark as a father's day gift. I was sceptical about it, but I tried it on the interior of the Jeep after taking the dogs for a ride while doing errands.
I coold not believe the power that little sucker has! I used the small hose and nozzle attachment, and it took all of the dog hair off the rear seats!
The only down side is that the motor generates a lot of heat...be careful when using it!
