Scrubber and Battery Maintenance Tips


Scrubber Maintenance


  1. Raise the squeegee assembly off the floor and wipe the blades down with a damp towel. Be sure to store squeegee in the UP position.
  2. Tilt machine back (after squeegee is UP), then remove and clean the pad driver(s)/brush(es).
  3. Drain both recovery and solution tanks completely of water and solution.
  4. Rinse out recovery tank with clean water, and remove any debris from inside tank. Remove clear lid off the tank and remove drain hose cap to allow tank and hose to dry/breathe.
  5. Remove the float shut-off filter inside the recovery tank and rinse it with clean water.
  6. Clean the machine with an approved cleaner and a damp towel.
  7. Recharge the batteries.



  1. Check fluid level in batteries.
  2. Check batteries for loose or corroded cables.
  3. Keep battery tops clean from corrosion.



  1. Check the scrubber for leaks and tighten any loose fasteners.
  2. Lubricate all grease points and pivot points with silicon spray or approved grease.
  3. Place machine over a floor drain. Flush the solution system by pouring 3 gallons of hot water and approved alkaline detergent into the solution tank and running the machine (with solution control on) for 45 seconds. Turn machine off and let it sit overnight. The next day, drain the remaining solution and rinse the solution tank out with clean water.


Daily Storage

ALWAYS... DRAIN both tanks, store machine INDOORS, in a DRY area, in the UPRIGHT position, with the SQUEEGEE UP off the floor, and the PAD DRIVER/BRUSH UP off the floor. If storing machine in an area with freezing temperatures, drain ALL of the fluids out of the machine to prevent damage.


Battery Type


Lead acid batteries are generally classified by application (what they are used for) and by construction (how they are made). Deep-cycle batteries are used for various types of applications specific such as RV, golf cars, renewable energy, and marine.


There are two popular construction types: flooded batteries (wet) and VRLA batteries (Valve Regulated Lead Acid). In the flooded types, the electrolyte is a solution of sulfuric acid and water that can spill out if the battery is tipped over. In VRLA batteries, the electrolyte is suspended in a gel or a fiberglass-mat (AGM technology), allowing these batteries to be mounted in a variety of positions.
Battery Inspection and Maintenance

TIP: For best battery performance, keep batteries charged at all times.
Do not let them sit in a discharged condition.

WARNING! Batteries are dangerous! Batteries emit hydrogen gas and an explosion or fire can result.
Keep sparks and fire away from batteries at ALL times.

  1. Whenever servicing batteries, be sure to wear protective gloves. Avoid contact with battery acid at all times.
  2. Use only distilled water to water batteries at least once a week.
  3. Always follow the battery charging directions.
  4. Keep battery tops and terminals free from corrosion. A strong solution of baking soda and water is the best way to keep the batteries corrosion free. IMPORTANT: Do not allow the baking soda/water solution to enter the battery cells!
  5. Use a wire brush with the baking soda solution to properly clean the battery posts and connections.
Check battery connections for wear and loose terminals. Replace any cables that are damaged frayed, or corroded.

Battery Charging

TIP: For best battery performance, keep batteries charged at all times. Do not let them sit in a discharged condition.


ATTENTION: To prolong the life of the batteries and to provide optimum machine performance, ONLY recharge the batteries after a total of 30 minutes of use or more. Do not leave batteries discharged for lengthy periods.


WARNING! Use only approved chargers with the following specifications:

  1. Automatic shut-off circuit
  2. Deep cycle charging
  3. Output current of 9-20 amps
  4. Output voltage of 24 volts


WARNING! Batteries are dangerous! Batteries emit hydrogen gas and an explosion or fire can result. Keep sparks and fire away from batteries at ALL times.

  1. When charging the machine, make sure the battery compartment is left open.
  2. Place the charger and the scrubber in a well-ventilated area.
  3. Turn the machine OFF.
  4. Open the hinged recovery tank to expose the battery compartment. Unplug battery pack from the machine.
Check the fluid level in each battery cell. Do not charge batteries unless the fluid is slightly covering the battery plates. Do not overfill the batteries. Overfilling may cause the batteries to overflow during charging due to expansion. Replace the caps prior to charging.
  1. FIRST, plug the red connector on the approved charger into the red connector of the battery pack. SECOND, plug the approved charger into a grounded wall outlet. (Do NOT plug the charger into the wall outlet first.)
  2. Flip up the recovery tank “kick stand” and gently lay the recovery tank down until it rests on the stand.
  3. The charger will automatically begin to charge the batteries. It will automatically shut down once the batteries are fully charged.
  4. Upon completion of charging, first unplug the charger from the wall outlet, and then disconnect the charger from the machine.
  5. Check the battery level after charging is complete. If fluid level is low, add distilled water to bring the fluid level up to the bottom of the sight tubes. Replace the caps and wipe the batteries down with a towel.


Trouble Shooting Batteries


  1. Check terminal post connections for any that may be loose or have corrosion.
  2. Check cells with a hydrometer and note the specific gravity in each.  A variation of .030 is poor.
  3. Check the voltage of each battery (must be disconnected).  12 volt batteries should read 12.7 volts and 6 volt batteries should read 6.3 volts to be considered “fully charged”.
  4. Recharge batteries if everything up to this point checks out ok, and repeat process of checking all cells specific gravity and voltage.
If poor run time is noted (less than ½ normal), one or more of the batteries need replacement.
