To be honest I didn't expect the quality or quantity that I received in this box. I'm pleasantly surprised. I have an iRobot Roomba 600 series. I love it when it works to keep pet hair at bay, but I recently lost my brush and needed new brushes. I got so much more with this box. cleaning tools. new brushes, new filters, I changed everything, everything is tight and tight, and Stan (Lee ;) is fine again!
