HOW THE MACHINE WORKS
Conventional Scrubbing:
Water and detergent from the solution tank flow to the
floor through a manually controlled solution valve. The
brush uses the detergent and water solution to scrub
the floor clean. As the machine moves forward, the
squeegee wipes the dirty solution from the floor into
the recovery tank.
Foam Scrubbing (FaST Model):
(FaST-- Foam Scrubbing Technology)
Unlike conventional scrubbing, the FaST system
injects the patented FaST--PAK concentrate formula
with a small amount of water and air onto the floor.
The mixture creates a large volume of expanded wet
foam for the brush to scrub the floor clean. As the
machine moves forward, the foam collapses and the
squeegee wipes the dirty solution into the recovery
tank leaving the floor clean, dry and residue free.
ec- H2O Scrubbing (ec- H2O Model):
(ec--H2O--electrically converted water)
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. The converted water attacks the dirt, breaks it
into smaller particles, and pulls it off the floor surface
allowing the machine to easily scrub away the
suspended soil. The converted water then returns to
normal water in the recovery tank.
