Remove the Filter. Shake it over the garbage can. This will be full of dirt, lint, and sand. I run water through the rounded point of the filter from outside and then flush water through both outsides and set it aside.

Pull the filter tube and rinse it out.

Eject the brush by pressing the button next to the vacuum tube.

Lift out the battery and set it on the charger (if you have an External Charger) Otherwise, just set it away from splashing water for now.
