Review on Enhance Your Roomba with efluky 3500mAh Ni-MH Replacement Battery and Accessory Kit for iRobot Roomba 700 Series by Gary Konduru

casters are too thick. Roomba was very nervous with them. I had to trim the brushroll to get it working. It still makes extra noise. Filters get stuck in the holder and break when removed. You can potentially damage the retainer. The rotating brush (three arms) is the only thing that works well. The rest doesn't fit.
