Turn off the vacuum and unplug it. Move the vacuum close to a garbage can.
Press the button on top of the dirt container lid to raise and remove the container.
Remove the filter from inside the container.
Tap the filter against the side of the garbage can until all of the loose dust particles fall from the filter. Shake loose any particles from the container in the same manner.
Run cold water over the filter, turning the filter so the stream washes away all the dirt particles. Do not use soap, as it could ruin the filter. Do not use brushes or sponges for the same reason.
Allow the filter to air dry thoroughly for 24 hours. Install another filter if you must use your Dirt Devil in the meantime.
Install the clean filter in the dirt container and then reattach the container to your Dirt Devil.
