These base replacement AirClean foam filters in front of the motor are compatible with the Shark IQ RobotRV1001AE/UR1000SR. It fits inside the cylinder but is longer than 3.7 inches (longer from 1/4 inch to 1/2 inch). Pros - I can always cut and customize what I need. Cons - You need to find a sharp blade I have no complaints, for the price I got 4 filters free while with Shark I only get 1 plus postage.
