How This Machine Works

The Chariot® is a battery powered, self-propelled, hard
floor scrubber intended for commercial use. The
appliance applies a cleaning solution onto a hard floor,
scrubs the floor with a brush, and then vacuums the
soiled water back into the recovery tank.

The machine's primary systems are the solution
system, scrub system, recovery system, and operator
control system.

The function of the solution system is to store cleaning
solution and deliver it to the scrub system. The solution
system consists of the solution tank, strainer, metering
valve and solenoid valve. The solution tank stores
cleaning solution (water and detergent) until it is
delivered to the scrub system. The strainer protects the
valves from debris. The solenoid valve automatically
prevents solution flow unless the scrub brush is turned
on and the machine is being propelled.

The function of the scrub system is to scrub the floor.

The disk scrub system consists of one rotary type disk
scrub brush, motor, scrub deck skirt and lift actuator.
The brush scrubs the floor as the motor drives the
brush. The brush drive hub allows the scrub brush to
follow irregularities and changes in the floor without
loosing contact with the floor. The scrub deck skirt
controls the cleaning solution on the floor so that the
squeegee can pick it up.

The function of the recovery system is to vacuum the
soiled water back into the recovery tank. The recovery
system consists of the squeegee, vacuum motor, float
ball, recovery tank. The squeegee wipes the dirty
solution off the floor as the machine moves forward.
The vacuum motor provides suction to draw the dirty
solution off the floor and into the recovery tank. The
float ball filter protects the vacuum fan from debris and
foam. The recovery tank stores the dirty solution.

The function of the operator control system is to control
the direction and speed of the machine. The directional
control system consists of the direction control drive
reset switch, throttle pedal, emergency stop/brake
switch, steering wheel, propel controller, and drive
wheel. The directional control drive reset switch signals
forward or reverse direction and makes sure the
operator is on the platform before machine will propel.
The controller interprets signals from the throttle pedal
to command the drive wheel to propel or slow the
machine. The steering wheel points the drive wheel in
the direction desired by the operator. The parking brake
automatically engages when the operator stop the
machine. The emergency stop/brake can be used to
hold the machine on slopes.

The cylindrical scrub system consists of two cylindrical
brushes, motor, side squeegees, and lift actuator. The
two counter rotating brushes scrub the floor, driven by a
single motor. The brush deck “floats” with constant
brush pressure. The side squeegees keep the cleaning
solution within the brush deck width, allowing the main
squeegee to pick the solution up.

1. KEY SWITCH

Controls the power for machine functions.
To turn the machine power on, rotate key clock­wise.
To turn the machine off, rotate key counterclock­wise.
When the key is turned on the battery symbol will
flash once and stay on continuously.

This safety feature is designed to cut all power to
the machine at any time and apply parking brake.
To shut the machine power off, push the
Emergency Stop Switch, this will also engage the
parking brake and cause the machine to stop
immediately.
To reset the machine, rotate the switch clockwise.

3. DIRECTIONAL CONTROL / DRIVE RESET
SWITCH

This safety feature is designed to ensure safe
engagement of propel drive. Each time the
machine power is turned on, or each time an
operator steps on to the platform, the Drive Reset
Switch must be pushed before machine will propel.
The switch controls the direction of travel of the
vehicle. The lighted arrow on the switch indicates
direction of travel.
To travel forward, press the top of the switch.
To travel in reverse, press the bottom of the switch.

Operations

4. THROTTLE PEDAL

Controls the speed of the vehicle within the speed control setting selected. Pressing the pedal causes the
machine to travel in the direction selected by the Directional Control Switch.
To increase speed, increase pressure on the pedal.
To decrease speed, decrease pressure on the pedal.

5. HORN BUTTON

The horn is activated by pressing the horn button.

6. STEERI N G WHEEL

The steering wheel turns the front wheel causing the machine to change direction.

7. SPEED CONTROL

Controls the maximum speed of the machine. There are two settings, slow and fast.
To change speed, rotate the dial to either slow or fast position. The slow position is to the left (counterclock­wise), fast to the right (top position).
The throttle pedal will always regulate the speed between 0 and maximum.

Operations

8. BATTERY DISCHARGE INDICATOR

Indicates the charge level of the batteries.
The indicator will be illuminated if the batteries have a sufficient charge. A slow, continuous flash indicates the
batteries require charging.

The Battery Lockout function will activate when the batteries are low.
Once active, the LED status indicator will begin to flash slowly and the controller will inhibit the scrub motor and
water solenoid. The vacuum and drive remain functional. The “vacuum only” selection (position ‘B’) can be
used to vacuum up any remaining water. Return the unit to the charging station and charge the batteries.

NOTE: Continuing usage may damage the batteries.

When the machine is left overnight with less than a full charge, the display may initially indicate a full charge. It
will also indicate a full charge if the batteries are disconnected, then reconnected. After a few minutes of
operation the indicator will give the correct charge level.

Scrub Controls

1. FUNCTION MODE SWITCH

The first two positions are for transport only. See drive controls section.

Light cleaning

This mode is used for light cleaning. In this mode the machine will propel at fast speed. The
‘floating’ scrub deck and squeegee is in the down position. The water will flow. Water will auto­matically shut off in neutral and restarts when scrubbing is resumed. The vacuum will draw the
water into the recovery tank.

Deep cleaning

This mode is used for deep cleaning. In this mode the machine will propel at a low speed. The
‘floating’ scrub deck and squeegee is in the down position. The water will flow. Water will auto­matically shut off in neutral and restarts when scrubbing is resumed. The vacuum will draw the
water into the recovery tank.

Operations

Vacuum only mode

This mode is used for picking up solution only. The brush and water will both be up and off. In
this mode the machine will propel at fast speed. The squeegee is lowered and the vacuum
will come on.

Double Scrub cleaning (with chemical metering on equipped models)

This mode is used for putting down solution and scrubbing without picking it back up. The
squeegee is set manually by connecting the two double scrub support cables. In this mode
the machine will propel at a slow speed. The scrub deck will lower. The solution will flow. The
brush and water will shut off when the machine is in neutral. They will resume when propelling
is resumed.

Light cleaning with chemical metering

Chemical dilution rate to be set by chemical metering selection switch.

Deep cleaning with chemical metering
