Aqua Pro Vac recommends keeping the water in the extractor clean and free of the detergents. The customer can use any brand of liquid or powder foamless carpet cleaner. The company recommends "The Totally Awesome" in Los Angeles, which is inexpensive and can be found at the most Dollar $ General Stores.
Aqua Pro Vac recommends that you need to vacuum the carpet or upholstery to remove any particles like dust or debris. Best practices for mobile car groomers over the past 10 years have included using a cleanser mixed with water in a spray bottle, spraying the mixture on the carpet and using a drill brush to agitate the fuzz.
Grab the nozzle and place it on the detachable recycling bin on the vacuum cleaner and hold the trigger to release the remaining solution until it's empty when you're done cleaning carpet or upholstery or stairs. Then turn off the pump and disconnect the spray hose. Aqua Pro Vac requires you to empty and rinse the solution and recovery tanks and then rinse the nozzles and hoses with water.
Aqua Pro Vac recommends topical cleaning of the stain with a concentrated cleaning solution in a spray bottle before using the product for a full cleaning if you're working on a heavy stain. Let it sit on the carpet for a minute and then machine through two passes. This will allow you to more successfully remove the stain completely.
