SANITMAX SM350 Commercial Walk-behind Carpet Extractor is a powerful carpet cleaning equipment that efficiently removes dirt, stains, and debris from carpet fibers.

The machine consists of a cleaning solution tank, a recovery tank, and a powerful suction motor. It jets a mixture of water and cleaning solution into the carpet and then uses the strong suction motor to extract the dirty liquid back into the recovery tank.

It is an excellent way to deep clean and refresh carpets and can help prolong the carpet's life. It is also standard equipment for professional cleaning services. 

This SM350 Walk-behind Carpet Extractor is perfect for cleaning large carpet areas, such as hotels, offices, airports, and other commercial and industrial settings, and public spaces where large amounts of foot traffic can result in heavy soiling and stains on carpets.

The SM350 Carpet Extractors can also be used in residential settings to clean carpets, especially in homes with pets or heavy soiling. The machine works by injecting a cleaning solution into the carpet and using water and suction to remove dirt and stains.
