HOW THE MACHINE WORKS

Conventional Scrubbing:

Water and detergent from the solution tank flow to the floor through a solution valve. The brushes use the detergent and water 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 activated Scrubbing Technology)

Unlike conventional scrubbing, the FaST system injects the 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 recovers the dirty solution into the recovery tank leaving the floor clean, dry and slip 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.

BRUSH AND PAD INFORMATION

For best cleaning results use the appropriate brush type for your cleaning application. Refer to the Parts manual for part number information.

Polypropylene Bristle Scrub Brush (Black) --

This general purpose polypropylene bristle scrub brush is used for scrubbing lightly compacted soilage. This brush works well for maintaining concrete, wood and grouted tile floors.

Soft Nylon Bristle Scrub Brush (White) --

Recommended for cleaning coated floors without removing finish. Cleans without scuffing.

Super Abrasive Bristle Scrub Brush (Gray) --

Nylon fiber impregnated with abrasive grit to remove stains and soilage. Strong action on any surface.

Performs well on buildup, grease, or tire marks.

Polishing Pad (White) --

Used to maintain highly polished or burnished floors.

OPERATION

Buffing Pad (Red) -- Used for light duty scrubbing without removing floor finish.

Scrubbing Pad (Blue) -- Used for medium to heavy--duty scrubbing. Removes dirt, spills, and scuffs and leaves surface clean ready for recoating.

Stripping Pad (Brown) -- Used for stripping of floor finish to prepare the floor for recoating.

Heavy Duty Stripping Pad (Black) -- Used for aggressive stripping of heavy finishes/sealers, or very heavy duty scrubbing.

Frequently asked questions

What kind of detergents can I use with the conventional scrubbing mode?

Only commercially approved cleaning detergents should be used. Using other detergents may damage the machine and void the warranty.

How do I know when to replace the brushes or pads?

The manual recommends replacing the brushes when they are worn to 5/8” (15mm). Pads should be replaced when worn. The document also specifies when to rotate brushes or pads.

How do I charge the batteries?

Connect the charger's AC power supply cord into a properly grounded receptacle and then connect the charger's DC cord into the machine's battery receptacle. The charger will automatically begin charging and shut off when fully charged.
