The dog hair in my kitchen was driving me crazy.  This vacuum was the answer I was looking for.  At under $20, it is a great buy.  It's basically a dustbuster with a larger head, a handle and a power cord.  No bending over or recharging.  While I wouldn't use it for my regular household vacuuming chores or on carpets, it's great for a quick once-over on hard floors, especially for pet hair.  It picks up only on the forward motion but that hasn't been a problem for me.  I am pleased with this purchase and have recommended it to a few friends with pets.
