Review on CyberTech Replacement iRobot Roomba 3 Armed Side Brushes for 500, 600, 700 Series (Excluding 645, 655, 675 & 670, 671, 690) by Molly Carlson

I was a little wary of buying these as some reviewers complained that they didn't fit or no screws were included (although I had freaking original screws) . none of my business). Thankfully, the brushes fit perfectly and don't seem to affect Roomba's performance in any way. They looked and fit exactly like the Original Equipment Manufacturer (OEM) side brushes, but the quality is definitely not the same. My only complaint is that after less than 4 months of use, the brushes on the first ones are badly worn, deforming significantly and will likely need to be replaced soon. Maybe it's just its lifespan, but I've had an OEM side brush on a Roomba for over 4 years and it's held up much better. Of course when I replaced it it was in pretty bad shape but it took a couple of years for the bristles to start deforming like they did after only a few months. They're half the price of OEM but I suspect they last less than half so it might be worth just paying more for the original.
