To use a Hoover steam vac, vacuum the area thoroughly. Fill the Steamvac tank with a mixture of the provided Hoover cleaning detergent and water. Step down on the handle release pedal on the right side of the device, then press the pedal on the left side to turn it on. Squeeze the trigger while pushing the Steamvac forward once, then backward. Release the trigger, and push the Steamvac forward and backward again. Repeat this process as needed.
For deeply set or tough stains, pretreat the area by spraying it with carpet or upholstery precleaning solution. If the stain does not loosen, gently scrub the area with a hard-bristled brush. Because the Steamvac trigger releases the cleaning solution and water, don't run more than four back-and-forth strokes using the trigger to avoid saturating the area.
To get the best results, keep the Steamvac nozzle flat against the area at all times. This ensures that when the trigger has been pulled, the cleaning solution is applied to the problem areas and the Steamvac brushes work directly into the surface of the carpet or upholstery. Because the carpet stays damp after being cleaned, start using the Steamvac at the end of the room farthest from the door to avoid soiling the surface further.
