Review on Replacement Parts for iRobot Roomba i7 i7+ i6 i8 i8+ i3 i4 E5 E6 E7 Vacuum Cleaner - iRobot Roomba i8 Replenishment Kit (1 Rubber Brush, 2 HEPA Filters, 2 Brushes) by Lindsey Braaten

Not as high quality as original item but they work well. I would buy again despite the differences/issues just to save money. The light green roller was the wrong length. The roller was installed normally but made a terrible noise during operation. I fixed it by trimming the pad with scissors. The design of the dark green roller brush is different from the original, but it works perfectly.
