This is an excellent alternative to the full priced Roomba replacement filters. The rollers, filter and sweeping arms all work great! And they were easy to install.  Replacement brushes also included a replacement screw for each brush in the event you loose one. Awesome, great replacement parts to replenish my roomba 980 at a great price.
