Review on MZY LLC 12 Pack Hepa Filter Replacement Filters for iRobot Roomba 800 900 series - Models: 860, 870, 871, 880, 960, 980 - Robotic Vacuum Accessories by Jonathan Unruh

I had high hopes for these filters despite some critical reviews and they fit my iRobot Roomba 880 perfectly! However, after 2 uses, I understand why there are critical reviews. After both uses (no more than 100 square feet of laminate flooring and 1 very thin carpet) Roomba's dust bin was empty and there were large clumps of dirt all around our carpet! And even after 6 hours later, carefully removing the mesh lining at the bottom of the filter and running Roomba through the same area, the dust bin was empty and the dirt was just scattered and deposited in the same spots on the carpet! Don't waste your money on these inferior imitations! Despite the higher cost, stick with iRobot branded filters. This saves you a headache.
