BASIC OPERATION
WARNING!!!!
 Do Not Use or Pick Up Flammable Materials with the Mopit.
 Do Not Use Mopit Near Flammable
Liquids or Vapors.
 Disconnect Battery Cables and
Charger Cord Before Servicing.
 Do Not Use or Store Outdoors.
Before using the Mopit 3.0 you need to fill
it with water and cleaning solution.
Filling The Fresh Water Tank
This is where you fill the Mopit with water. It
is best to add the cleaning solution after you
have filled the tank with water. It is ok to let
water stay in the fresh water tank for an ex-
tended period of time.
Using Mopit Cleaning Solution
Mopit cleaning solution is very concentrated.
It only takes one ounce of solution per Mopit
fill for normal cleaning. For greasy floors you
can use 2-3 ounces of solution per
Mopit fill.
The fresh water tank cap is a one
ounce measuring cup, you can also
order a one ounce per pump dis-
penser by calling us at 1-800-290-
2833

BASIC OPERATION
Water Level Gauge
This is the water level gauge.
Even though the gauge
shows 4 gallons the actual
fresh water capacity is 5
gallons.
The Mopit Has 3
Switches
The Brush Switch
The Solution Switch
The Vacuum Switch
Simply turn on all
three switches and
walk.
The water switch will
work only when both
the vacuum and water switches are on.
The Mopit 4 has brush assist, so the brush will help to pull the Mopit
along the floor, making it effortless to push.
When operating the Mopit you may walk at a normal pace.
If there is a really dirty area, cleaning performance is increased pushing
the Mopit slower.

BASIC OPERATION
Draining The Dirty Water
This is the dirty water drain
hose
Simply remove the cap and let
the drain hose down onto a
floor drain. After draining, be
sure to put the cap on tightly.
If the cap is not screwed on
tightly the machine will lose
suction power. It is important
to drain the dirty water tank after each use. If dirty water sits in your
dirty water tank for an extended period of time, your machine will start
to stink.
Water Valve
The water control valve
controls how much water
goes onto the floor.
The water valve is full on
when the black valve handle
is horizontal, and full off
when the handle is vertical.
To lower water output,
position the valve between full on and full off.
Transporting The Mopit
When moving the Mopit, tip it on it’s back
transport wheels and move it like an upright
floor vacuum.

BASIC OPERATION
Squeegee Lift
Pedal
The squeegee lift
pedal is used for
deep cleaning. It
allows you to make
multiple scrubbing
passes without pick-
ing up the water on the floor. This is called double scrubbing. To lift the
squeegee, push the pedal down and slide it to the left. To drop the
squeegee, push the pedal down and slide it to the right.
Charging The Mopit
The Mopit is battery operated. The charger should be plugged into the
Mopit whenever it is not being used. The battery charger can be con-
stantly plugged into the wall. You do not need to wait until the batteries
are fully charged to use the Mopit. You do not need to run the batter-
ies down before you can charge the Mopit. To charge the Mopit plug
the Battery charger into the wall. The on-board charger has three indi-
cator lights. The red power light will
always remain on. When the power
light and yellow charge lights are on the
Mopit is charger. The Mopit is fully
charged when the red power light and
the green charger lights are on. The
Mopit 4 is also available with an off-
board charger option.

Draining The Fresh Water Tank
Occasionally you may need
to drain the fresh water
tank. The tank will need to
be drained before shipping.
There is no harm in leaving
water in the fresh water
tank for an extended period
of time. You will want to
have the machine outside
or positioned over a floor
drain when you drain the
tank. To drain the tank pull off the tubing from the brass hose fitting,
and the water will immediately begin rushing out of the tank.
Cleaning The Water Filter
When you are not getting enough water onto the floor, clean the water
filter. Before you clean the fresh water filter make sure that the water
valve that is just above the filter, is turned off. Open the battery cover
by opening the bolt latch. Pull off the tubing connected to the solenoid.
Unscrew the base of the filter housing and remove the filter. Wash the
filter out in running water, and reassemble. Don’t forget to open the
manual water valve.

MAINTENANCE / SERVICE
Changing The Squeegee Blade
On average the squeegee blade will need to be changed every 6-8 weeks. If the
machine is leaving streaks, and not picking up all of the water, or the Mopit is
not cleaning very well, check your squeegee blade for wear. The squeegee
blades are reversible, so you can reverse the blade for longer squeegee life.
Often you will only need to change the rear blade, as the front blade is a more
durable material, and should last much longer than the rear blade. The front and
rear squeegee blades have different bead shapes. The rear blade bead is round
and the front blade bead is triangle, so you cannot install the blades backwards.
1. Tip the Mopit on its back
2. Remove the squeegee wheel
3. Slide out the old blades
4. Slide in reversed, or
replacement blades
5. Replace squeegee
wheels if worn

Adjusting The Brush Pressure
WARNING: Adjusting the brush too low can damage the brush motor
and lessen the cleaning performance.
As the scrub brush wears,
your brush pressure on
the floor will lessen. To
compensate for brush
wear, adjust the wheels to
lower the brush head.
To adjust the brush pres-
sure, tip the machine on its
back.
Insert a the included 5/32
Allen wrench into the
wheel block windows.
Turn the Allen wrench counterclockwise one complete turn. Adjust
both wheels by the same amount.
IMPORTANT: You must adjust each wheel by the same amount. Failure to
do so will cause un-even brush wear. If you don’t know if the wheels have both
been evenly adjusted, turn the screw as far as you can clockwise, then begin
again to adjust each wheel counterclockwise by the same amount. It is wise,
with each full turn of the screw, to stand the machine back up and check the
brush deflection from the side of the machine. We recommend one inch of
brush of the brush touching the floor but only a 1/4 inch of the brush
height on the floor. Check the brush deflection from the sides of the brush
hood while the brush is spinning. Brush deflection means the amount of
the brush touching the floor. It is easiest to see using a flashlight.
Scan this QR code with your smart phone to watch how to
adjust the brush pressure. You can view all of our Mopit
movies on the “Mopit Channel” at www.youtube.com.

Cleaning The Recovery Tank
If the recovery tank is not cleaned out regularly the Mopit will begin to
stink when used. To clean, remove the clean out access cap by twisting
it counterclockwise. Open the drain hose and place it over a floor drain.
Use a hose with a sprayer to spray out the recovery tank. Spray the
Vacuum ball screen. It may also help to back flush the drain hose.
After spraying out the tank, use a trigger sprayer to spray undiluted
bleach all over the inside of the recovery tank. Let the tank sit with the
clean out cap and drain hose cap off until the inside of the recovery tank
is dry. If your machine still has a foul odor order some Mopit deodor-
izer from Spectrum.
