UNPACKING:
Carefully unpack and inspect your Agitator-20 for shipping damage. Each machine is tested and
inspected before shipping. Any shipping damage incurred is the responsibility of the carrier. You
should notify the carrier immediately if you notice damage to the box or to the machine or parts.
CLEANING SOLUTIONS:
We recommend a neutral pH, low foam cleaner, applied to the carpet as a pre-spray.
MAINTENANCE:
After each job, rinse the recovery tank and dump hose with clear water. Clean both filters after each
job. Lubricate the wheels and quick disconnects with an all purpose silicone spray, as needed. The
vacuum motor may require new brushes after 1000 - 1500 hours. An impeller replacement kit for
the dump pump is enclosed with these instructions: use the replacement kit when the dump pump
performance falters. Clean the body with an all purpose detergent, and protect it with an automobile
interior spray protectant.
DO NOT OPERATE THE MACHINE UNTIL YOU HAVE READ THIS SECTION.
IMPROPER USE MAY RESULT IN PERSONAL INJURY OR PROPERTY DAMAGE.
IMPROPER USE WILL VOID THE WARRANTY.
yAlways use a defoamer when foaming occurs to prevent vacuum motor damage.
yNever use water above 130 °F (54 °C).
yDo not store outdoors. Avoid extremes in temperature.
yUse approved chemicals only. All chemicals should be mixed thoroughly. A pH between 6 and 9
is recommended. The use of high alkaline detergents or strong acids will accelerate the wear of
the seals, and will void the warranty.
yCarpet cleaning chemicals may affect bare floor finishes. Take precaution to keep chemicals
from surfaces other than the carpet.
yAll cords must have a rating of at least 12/3 (#12 cord). Replace the plug immediately if the
ground prong becomes damaged or is broken off.
yWear clean tennis shoes or non-slip shoes when working with a carpet extractor. Street shoes or
rubber sole shoes will release absorbed dirt or grease, when wet, onto the carpet.
yWet shoes can be a slipping hazard on bare floors -- be sure to dry your shoes before walking
onto bare floors.

IMPORTANT SAFETY INSTRUCTIONS
This machine is only suitable for commercial use, for example in hotels, schools, hospitals, factories,

•Connect to a properly grounded outlet only. See Grounding Instructions.
•Liquid ejected at the spray nozzle could be dangerous as a result of its temperature, pressure or
chemical content.
SAVE THESE INSTRUCTIONS

120VAC GROUNDING INSTRUCTIONS
This machine must be grounded. If it should electrically malfunction, grounding provides a path of least
resistance for electric current to reduce the risk of electric shock. This machine is equipped with a cord
having an equipment-grounding conductor and grounding plug. The plug must be plugged into an
appropriate outlet that is properly installed and grounded in accordance with all local codes and
ordinances.
DANGER!
Improper connection of the equipment-grounding conductor can result in a risk of electric shock. Check
with a qualified electrician or service person if you are in doubt as to whether the outlet is properly
grounded. Do not modify the plug provided with the machine. If it will not fit the outlet, have a proper
outlet installed by a qualified electrician.
This machine is for use on a nominal 120-volt circuit, and has a grounding plug that looks like the plug
illustrated in Figure 1 below. A temporary adapter illustrated in Figures 2 and 3 may be used to connect
this plug to a 2-pole receptacle as shown in Figure 2 if a properly grounded outlet is not available. The
temporary adapter should be used only until a properly grounded outlet (Figure 1) can be installed by a
qualified electrician. The green-colored rigid ear or tab extending from the adapter must be connected to
a permanent ground such as a properly grounded outlet box cover. Whenever the adapter is used, it must
be held in place by a metal screw. Grounding adapters are not approved for use in Canada.
Replace the plug if the grounding pin is damaged or broken.
The Green (or Green/Yellow) wire in the cord is the grounding wire. When replacing a plug, this wire
must be attached to the grounding pin only.
Extension cords connected to this machine should be 12 gauge, three-wire cords with three-prong plugs
and outlets. DO NOT use extension cords more than 50 feet (15 m) long.
PLEASE NOTE: FOR NORTH AMERICA ONLY

AGITATOR 20, 120V
Switch and Indicator Light Operation
The Power ON/OFF switch on the front panel
will supply power to all the systems, however,
only the vacuum will turn on automatically
with this switch.
The Push Button on top of the back of the
handle will activate the Agitator bar and the
Spray. This button is positioned for ease of
use when operating the machine.
The Dump Pump will turn on and off during
use as the sensor in the Recovery Tank detects
the level of water.
A sensor in the Recovery Tank will detect
foam, when present, and activate a solenoid to
allow defoamer to flow into the tank.
The indicator lights on the panel will turn on
when the associated function is operating.

1Always use a vacuum cleaner on the carpet in the treatment area before using the Agitator-20.
2Pre-treat spots, stains and heavy traffic areas before extraction. Consult your local distributor for
procedures and/or chemical advice.
NOTE: the Agitator-20. is intended to provide a clear water rinse and dirt extraction after
application of a pre-spray; however, a chemical injection system is available, as an option, to add
cleaning detergent to the Agitator-20’s solution line.
3Set up the hoses: Unscrew the aerator from the sink faucet, if applicable, and screw the adaptor
hose onto the threads on the faucet. Join the solution hose to the adaptor hose by connecting the
quick disconnects. Place the drain hose securely into the sink drain.
4Lay the hoses out, from the sink to the Agitator-20. Attach both the water supply hose and the
drain hose to the machine.
5Make sure there is defoamer in the defoamer bottle, if foam is present.
6Turn on the water supply. Be sure not to use water above 130 °F.
7Plug the power cord from the Agitator-20. into a wall outlet. Use a GFCI protected outlet if possible.
8Turn on the main power switch.
NOTE: It is best to clean around the perimeter of the room at first, so you can get as close to the
baseboard as possible. Use the right side of the machine against the wall for the best results.
After the perimeter has been cleaned, start cleaning on one side of the room, and work your way
across the room in over-lapping rows.
9When cleaning with the Agitator-20. tilt the front of the machine up and off the carpet by pushing
down on the handle, and move the machine forward across the carpet. Let the front of the machine
down and pull backwards as you activate the spray and the agitator button. Let off the spray
button about 12” before the end of the row so that the machine can recover all the spray that was
put down. Let off the agitator button when you reach the end of the row. Tilt the front of the
machine up and move the machine towards the top of the next row. Continue this way until the
whole room or the entire area has been cleaned.
10 At the end of each job, follow these instructions to rinse out the recovery tank and hoses:
move the machine near the sink. Leave it plugged in. Turn off the water faucet. Disconnect the
solution hose from the faucet and set the end of the hose in the sink. Fill a bucket with water, open
the lid to the recovery tank, and pour the water into the tank. Turn the dump pump on to send the
rinse water and residual dirt through the dump hose and into the sink. Repeat until clean.
When the rinsing is complete, leave the machine’s main power switch on just long enough to pump
all the water out of the machine and the hose. Turn off the main power switch, and unplug the
power cord.
Remove both the fabric pre-filter and the wire mesh filter, after each job, to clean and dry them.
Reinstall the filters after cleaning.
Disconnect the dump hose from the machine, and remove the adaptor from the faucet. Leave it
laying in the sink. Reinstall the aerator onto the faucet, if it had been removed. From the machine
end, coil up the hoses so any water remaining in them drains into the sink. Free the dump hose
from the sink drain. Wipe down the hoses and the machine.
