I actually agree with this completely and do the same thing at home. I also got tired of whacking the filter and worrying I was forcing dust deeper, and the quick tap outside then a lukewarm rinse with a gentle squeeze is the only thing that reliably brings suction back. Letting it air dry overnight keeps it safe for the motor, and having a spare set means you pop in a clean one right away so there is no waiting or fiddly steps. With two cats in the house this keeps hair from choking the intake, and the steps are simple enough to remember without a manual.
