The floor technicians at Pro-Kleen smarten up shag and refine tile with a combination of industrial-age steam power and cutting-edge technology. After a free estimate nails down a firm flat rate, berber inspectors put rugs through an eight-step process that includes inspection and pretreating stains. A truck-mounted Rotovac 360 machine dissolves soil, grease, and spots with 180-degree water before a high-powered vacuum extracts the mix, leaving behind soft, allergen-free fibers and terrified Lego people. The process removes most of the water it uses to saturate the fibers, reducing drying time to a few hours. All jobs are guaranteed and backed up with the promise to reclean any unsatisfactory jobs or refund the total cost.
