Roomba Jaggy Roller

I have a large dog and a large cat plus a wife with long hair so I have lots of hair in my house. The stock rollers that come with Roombas are designed to lift the hair and drag it to the center between the two rollers where it gets sucked up by the vacuum. If you run your vac everyday, this might work fine for you. If you don't, you end up getting clumps of hair left behind by the vac.

Upside: This roller picks up more hair even if you vac less often.
Downside: This roller is harder to clean takes a little more time.

This roller will work fine with i3 i3+ i4 i6 i6+ i7 i7+ i8 i8+J7 J8 /Plus E5 E6 E7 I,E & J Series. I own two I4s.

This should be printed vertically. You should use TPU. My TPU is 85 durometer and rollers last practically forever.

If you want to use two of these rollers in the same vacuum, print one even and one odd so that the two brushes don't constantly collide. I normally use one jaggy roller and one regular roller in my vacs.
