Once it has dried (we recommend waiting twenty-four hours before replacing the filter, just to be safe), slide the filter back in place. Insert the bottom half of the filter into the slots, and push the filter towards the housing until it snaps into place. It may help to hold the plastic tab down until the rest of the filter has been slid into place.

The motor filter is located at the bottom of the bag chamber. It is held in place by a plastic grid.Remove the filter and clean or change it as necessary. After it has dried for 24 hours, replace the filter with the grid side down. It will click when it is back in its proper position.

When that time comes, slide the exhaust filter's pegs into the two slots in the bottom of the housing and push the top of the filter away from you. For the best fit, hold down the plastic tab on top of the filter and release pressure once it has slid into place.

Pull the motor filter from the dust cup. We recommend waiting twenty-four hours after washing the filter before replacing it. Once it has fully dried, slide it back into place and reassemble the dust cup.
