I am very disappointed with these filters for my Neato. Initially I was very happy to use them - great price, nice looking material, easy to clean, direct fit and replacement. After they actually tried them, it turned out that the material used essentially completely blocked airflow to the naturally aspirated motor at the back. I mean, you put that filter in and you pretty much lose all your suction power - just put your hand behind the Neato when it's running and see how much air it blows out…
