If you have a pet and a carpet or rugs you should have a metal carpet rake for pet hair.

I just removed what seems to be an entire dog from our living room rug.

Basically these rakes use heavy-gauge metal spiral-wound wire to grab on to pet hair, it's kind of magical to see your rug change color lol.

Get one with a long handle so you don't need to bend over.

Note: can't use them on some types of of rugs, like wool or silk; so read the instructions/warnings!

@thomasfuchs You can get rubber rakes that work nearly as well and are less damaging to rugs.
