T350 9016417 (02-2021)

OPERATION

HOW THE MACHINE WORKS

Conventional scrubbing:

When using the conventional scrubbing mode, water and detergent mixture from the solution tank ﬂ ows to the ﬂ oor and the rotating brush(es)/pad(s) scrub the ﬂ oor clean. As the machine moves forward, the squeegee with vacuum suction picks up the dirty solution from the ﬂ oor into the recovery tank.

ec-H2O NanoClean Technology (option): When using the ec-H2O NanoClean technology, normal water passes through a module where it is electrically converted into a cleaning solution. The electrically converted water attacks the dirt, 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 results, use the appropriate brush or pad for the cleaning application. Listed below are brushes and pads and the applications for which each is best suited.

Stripping pad (Brown) - For stripping of ﬂ oor ﬁ nish to prepare the ﬂ oor for recoating.

Polypropylene Side Brush − For general sweeping of light to medium debris.

Heavy duty stripping pad (Black) - Used for aggressive stripping of heavy ﬁ nishes/sealers, or very heavy duty scrubbing.

Surface preparation pad (Maroon) - Used for very aggressive chemical free removal of ﬂ oor ﬁ nish to prepare the ﬂ oor for re-coating.

Tufted pad driver - Standard pad driver has short bristles, or “tufts,” on the back to hold the pad in place. This driver works with all Tennant pads except the black high productivity pad.

NOTE: The amount and type of soilage play an important role in determining the type of brush or pad to use. Contact a Tennant representative for speciﬁ c recommendations.

Soft nylon bristle scrub brush (White) - Recommended for cleaning coated ﬂ oors without removing ﬁ nish. Cleans without scufﬁ ng.

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 ﬂ oors.

Super abrasive bristle scrub brush (Gray) - Nylon ﬁ ber 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) - For maintaining highly polished or burnished ﬂ oors.

Bufﬁ ng pad (Red) - For light duty scrubbing without removing ﬂ oor ﬁ nish.

Scrubbing pad (Blue) − For medium to heavy duty scrubbing. Removes dirt, spills, and scuffs.
