The SUV

Dirt Devil Reaction, $170
Pros: For those who like to see their dirt get blasted, this aggressive-looking, bagless machine traps dirt in two see-through chambers (so you can be sure the dog hair is gone).
Cons: Testers said it was heavy and difficult to maneuver. Its decibel level on carpets hit 80.7, which is on the loud side.
