Remove the Swiffer pad from its handle by pulling the two pieces in opposite directions.
Flip the Roomba robot upside down and lay it on its top so that the wheels are exposed.
Identify the dust receptacle on the underside of the Roomba. It is a clear plastic container located opposite the Roomba's third wheel.
Cut two strips of duct tape approximately 2 inches in length and tape them to each end of the Swiffer pad.
Lay the Swiffer pad on top of the Roomba's dust receptacle, tape-side down, and affix the tape to the body of the Roomba.
Turn the Roomba back to its proper orientation with the wheels on the ground and set it in an area with hard floors. Press the button in the center of the Roomba to activate its cleaning function. Now the Roomba will continue to vacuum while the Swiffer pad will pick up the loose dust left behind.
