I struggle with the dog hair on my couch. It's a pain to have to drag my vacuum out and get the hose all hooked up, so I tried one of those lint roller things that are for pet hair. But after one swipe it's full and I have to tear off the first layer (which is a pain) so I ditched that pretty quick. I finally looked into a cordless handheld vacuum (like a dust buster) that is specifically for pet hair on couches and wow! i just got it yesterday and used it, and it's amazing! Easy to use and got ALL the hair!
This is what I ended up with, great price too!
