The Saber Compact is a battery powered, 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. The
traction model has a directional control system as
well.
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, valve and controls. The
solution tank stores cleaning solution (water and
detergent) until it is delivered to the scrub system.
The strainer protects the valve from debris. The
non-traction model has a ball-type valve which
controls the delivery of cleaning solution to the
scrub system. The traction model has a solenoid
type valve, which controls the delivery of cleaning
solution to the scrub system. The valve
automatically prevents solution flow unless the
scrub brushes are turned on and the machine is
being propelled. The solution control knob
controls the amount of cleaning solution delivered
to the scrub system.
The function of the scrub system is to scrub the
floor. The scrub system consists of a rotary type
disk scrub brush, motor, self-adjusting scrub deck
skirt, lift linkage and controls. The brush scrubs
the floor and 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 floor. The self-adjusting
scrub deck skirt controls the cleaning solution on
the floor so that the squeegee can pick it up. The
brush lift lever raises and lowers the scrub deck.
On the traction model the brush lift lever can be
locked into an increased brush pressured
position.
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, screen, recovery tank and
controls. 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 screen protects the vacuum fan from debris.
The recovery tank stores the dirty solution. The
float ball in the tank activates when the recovery
tank is full.
On the traction model, the function of the
directional control system is to control the
direction and speed of the machine. The
directional control system consists of buttons,
speed control knob/potentiometer, controller and
transaxle. The speed control knob actuates a
potentiometer, which signals speed. The
controller interprets the forward/reverse signals
from the buttons and the speed signal from the
potentiometer to command the transaxle to propel
the machine in the direction, and at the speed,
desired.
The buttons on the control handles signal forward.
When the reverse button on the control panel is
pushed, in addition to either button on the control
handles, reverse is signaled.
