ChomChom Roller Pet Hair Remover

Sticky lint rollers are a subscription in disguise: you peel a sheet, it fills up in ten seconds, and eventually you run out and buy more. The ChomChom is the version that never runs out. Rock it back and forth over the couch and its rubberized roller sweeps dog hair into a built-in chamber. When it's full, you pop the lid open and a satisfyingly gross wad of fur drops straight into the trash. No adhesives, no batteries, no refills, ever.

It also grabs the fine, woven-in fur that vacuums skate right over, which is why it has a cult following among people who own both a couch and a shedder. As a gift it lands with anyone whose dog has claimed the furniture: hand it over with a straight face and let them discover exactly how much hair was hiding in a sofa they thought was clean.
