Fill the SmartMix fluid canister with Bissell steam cleaning solution. Twist off the cap and pour in the solution until you reach the fill line.
Fill the water tank with tap water, again filling to the water line. Water temperature makes no difference. The water tank is located near the bottom of the unit and can be detatched from the base using the release lever at the top of the water tank. Snap the water tank back into place.
Turn on the Bissell Proheat and press the spray trigger. Keep in mind both fluid tanks need liquid in them for the unit to properly operate.
Push the Bissell Powersteamer over your carpeting, pushing back and forth. Clean your carpeting in square patches, cleaning approximately three square feet at a time as you clean. Move across the carpeting until all is cleaned and allow to air dry.
