Review on DerBlue Replacement Parts for iRobot Roomba 800 and 900 Series Vacuums with 5 Hepa Filters, 5 3-Armed Side Brushes, and 2 Sets of Tangle-Free Debris Rollers by Katresa Jones

ROLLERS: My original rollers were worn out so I fitted the first rollers from this DerBlue spares kit. Once the rumba reaches an area where the carpet was thicker (less passable), the carpet fibers will be pulled into the rollers, causing the rumba to stop and causing an error. The rollers have a slightly larger diameter. For that reason alone, I won't buy it again. SIDE BRUSH: Seems like a fairly simple component, but DerBlue's first side brush was the wrong size and kept getting stuck under the Roomba's wheel. The second wears out quickly, and one of the brush arms somehow constantly bends to the side. FILTER: You seem fine. The trash can is always full, like branded filters. I have a small handheld vacuum that I use to clean the filter. Keeps the filter running for quite a long time. Therefore only 1 of the 3 parts in this pack is considered usable. Roomba 980
