Remove the 13 screws (circled in yellow) using a phillips screwdriver.

Be sure to keep track of which screws go into which hole.

Remove the one screw (circled in red) that has a Torx head (might be Phillips head on some models).

The Torx screw is hidden under a rubber gasket. Carefully, lift up the gasket without damaging it to access this screw.

Remove the horizontal screw (circled in orange) that attaches the gray side panel (necessary to remove the white cap on the roller brush in step 8)
