Review on 🔍 Hongfa Replacement Roomba i7 i7+ i6+ Filters, 18 Packs Replacement Parts for i-Robot Roomba i7 7150 i7+/i7 Plus E5 E6 i6+ E7 i3 i3+ i4+ (4552) Vacuum, Roomba i & e Series Replenishment Filters by Elizabeth Pushkina

These filters clog up very quickly - I don't know what they are made of compared to the iRobot brand but now we keep getting cart empty and other error messages. iRobot brand filters last a very long time, only lasting a time or two before clogging. The brush that came with it doesn't seem to do anything. You can't use a handheld vacuum to clean the filters, which is something we've always been able to do with the iRobot brand. We are back to very expensive filters. I don't want them to destroy our iRobot.
