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
losing contact with the floor. The scrub deck skirt
controls the cleaning solution on the floor so that the
squeegee can pick it up.
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.
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.
