Pledge Fabric Sweeper for Pet Hair Review

As the owner of dogs...I am constantly using a lint roller and/or a vacuum to pick up after my pets.  We constantly have hair on the furniture, carpets, inside our cars, etc.  I saw these Pledge fabric sweepers at the store and decided to buy a package (2 come in a package) for $8 (on sale).  I thought this was a hefty price tag for only two disposable fabric sweepers, but I thought that I would give them a try before I judged based on the price tag.  My intuitions were right.
They work by the user rolling the device back and forth in small sweeps.  One of the rollers picks up the hair and the other roller rubs against the first one to clean it off and push the hairs into the stoarge area.  I first used one on our couch.  It picked up some of the hair...then I used it on some of our throw pillow...it did a decent job getting the hairs off when I pulled the fabric very taught.  I wasn't getting very much in the collection area, so I thought I would go ahead and try it on the floor before I vacuumed.  It did pick up hair---but only on one of the brushes and the rest of the hairs balled up and fell off in clumps. 

I'll stick to my lint rollers.  They give me much better results and are much more affordable.
