This is hands down the best, fastest pet hair removal tool I’ve ever used. It’s quite ingenious actually. The roller is actually more of a rocker, meaning it rocks and pivots back and forth as you “roll” it over things, and by roll it’s really more of a scraping action. As you push and pull the ChomChom, there are two sets of lint roller hairs that grab the fur and deposit it in the chamber (one set grabs the hair as you push, the other set grabs the hair as you pull). I LOVE how I can go over a lot of surface area before having to empty the chamber, like an entire couch, something that would’ve required three or four tape roller sheets or 10-15 mins of vacuuming. The only negative I suppose is that it does require the thing you’re rolling to be somewhat taut. I also wish the handle was a little more comfortable to use (the bottom side of the handle isn’t smooth — it’s like a grate. Check out my video review. Bottom line, get this ChomChom!
