The three-in-one carpet washing machine is a carpet cleaning and maintenance method that combines thorough carpet cleaning and maintenance cleaning. Spray the carpet on the carpet, and at the same time, the roller brush motor drives the roller brush to rotate at a high speed, dissolves the dirt at the root of the carpet with the detergent, sweeps it out, brushes the carpet, and finally absorbs the sewage through the high-power water suction motor. This conservation cleaning method dries faster blocks and leaves less carpet residue. And you can regularly use warm water (not more than 40 degrees) to spray, spray, and comb clean high-end carpets, which can guide high-end carpets such as combing pure wool and flocking, and reduce detergents and dirt in carpet cleaning. At the same time, it can effectively prevent the carpet from being damaged due to stains and dirt, excessive detergent deposition, and the carpet is wet for a long time and does not dry for a long time.
