OPERATION HOW THE MACHINE WORKS The scrub components of the machine are a solution tank, scrub brushes or pads, a squeegee, a vacuum fan, and a recovery tank. Water and detergent, from the solution tank, flow to the floor through a solution valve to the scrub brushes or pads. The brushes or pads scrub the floor. As the machine is moved forward the squeegee wipes the dirty solution off the floor, which is then picked up and drawn into the recovery tank.
OPERATION FaST SCRUBBING SYSTEM (OPTION) The FaST (Foam Scrubbing Technology) system operates by injecting the FaST PAK concentrate agent (A) into the system with a small amount of water and compressed air. This mixture creates a large volume of expanded wet foam. A The expanded foam mixture is then dispersed onto the floor (B) while the machine is scrubbing. When the squeegee picks up the mixture, the patented foaming agent has collapsed and is recovered into the recovery tank.
OPERATION ec- H2O SYSTEM (OPTION) The ec--H2O (electrically converted water) system operates by producing electrically activated water for cleaning. Normal water passes through a module where it is oxygenated and charged with an electric current. The electrically converted water changes into a blended acidic and alkaline solution forming a neutral pH cleaner.
