Machine Data Log/Overview
Overview
The Chariot® iExtract® CE26 is a battery powered, self-propelled Carpet Extractor intended for commercial use.
The machine is a dual mode; interim and deep extraction carpet machine. Interim mode applies solution at a low
flow rate agitated by the counter-rotating brushes with no solution recovery. Deep extraction applies solution at a
high flow rate agitated by counter-rotating brushes and recovered by the dual vacuum shoes.
The machine is designed to apply a cleaning solution onto carpeted floor, and scrub the carpet with two counter-
rotating brushes, then vacuum the soiled water back into the recovery tank.

Operations
How This Machine Works
The Chariot® iExtract® 26 is a battery powered, self-
propelled Carpet Extractor intended for commercial
use. The machine is a dual mode; interim and deep
extraction carpet machine. Interim mode applies
solution at a low flow rate agitated by the counter-
rotating brushes with no solution recovery. Deep
extraction applies solution at a high flow rate agitated
by counter-rotating brushes and recovered by the dual
vacuum shoes.
The machine is designed to apply a cleaning solution
onto carpeted floor, and scrub the carpet with two
counter-rotating brushes, then vacuum 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 is gravity fed. The solution system consists of
thesolutiontank,strainer,valve,manifoldandcontrols.
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 strainer
prevents debris from entering the supply lines, valve,
andmanifold.The valveautomaticallypreventssolution
flow unless the scrub brushes are turned on and the
machine is being propelled.
The function of the scrub system is to scrub the carpet
and lift and groom the carpet pile. The scrub system
consists of two cylindrical counter-rotating brushes, a
motor, lift actuator, and controls. The brushes scrub the
carpet as the motor drives the brushes. The counter-
rotating action of the brushes applies and agitates the
solution into the carpet.
The function of the recovery system is to vacuum the
soiled water back into the recovery tank. The recovery
system consists of two vacuum shoes, two vacuum
motors, float ball filter, and controls. The vacuum shoes
extract the dirty solution from the carpet as the machine
moves forward. The vacuum motors provide suction to
draw the dirty solution off the carpet 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 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 steps off the
platform. The emergency stop/brake can be used to
hold the machine on slopes.
NOTE: Impact to machine may cause damage.

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 while the system runs self-diagnostics and returns
scrub deck and squeegee to their raised positions, if necessary. The controller will not respond to other
commands until this routine is complete.
2. EMERGENCY STOP / BRAKE SWITCH
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. Excessive emergency stop usage can cause premature brake wear;
use only when necessary.
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.
Controls the direction of travel of the vehicle. The lit 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. STEERING 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 transport settings, slow and fast.
To change speed, rotate the dial to either slow or fast position. The speed for fast and slow are as indicated on
the control panel by the symbols shown below.The throttle pedal will always regulate the speed between 0 and
maximum.

8. BATTERY CHARGE LEVEL INDICATOR
Indicates the charge level of the batteries.
The meter display is divided into 10 bars. Bars illuminated on the far right indicate full charge. Bars flashing
near the left side indicate the batteries should be recharged. Further operation of the machine could damage
the machine or 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 meter will give the correct charge level.
9. HOUR METER
Records the number of hours the machine has been in scrubbing operation. This information is useful in deter-
mining when to service the machine.
