We Have Extended Our Services to Tile and Grout

Our new King Cobra® 1200 Pro device cleans multiple surfaces. This innovative machine power washes tile, grout, and other hard surfaces with 1200 psi. It immediately vacuums up the soiled water, leaving floors cleaner and drier than any other hard surface cleaning method currently available. Not only will this device clean hard surfaces, it is also a heated carpet extractor. With an adjustable 150 to 500 psi pump and instant 212F hot water at the wand tip, this machine is a perfect fit for maintenance or restorative cleaning. The King Cobra® 1200 Pro has achieved the Gold level of certification from CRI's Seal of Approval program.
