Congratulations,
You now own a piece of equipment that incorporates the latest in carpet cleaning
technology. The RX-20’s features will almost certainly increase the productivity of
you and your business, while decreasing the fatigue factor that may have prevented
you from going after some of the large cleaning jobs that are available to carpet
cleaners and maintenance professionals today. With competition as strong as it is in
most communities, you have invested in not only a cleaning tool, but a marketing tool
that will enhance your professional image in every way.
The RX-20 is REVOLUTIONARY. Your foresight in purchasing this ultimate “cleaning
machine” will be rewarded with the knowledge that you care enough to give your
customer the maximum cleaning process available.
Using the RX-20 in your business will turn you into a professional carpet cleaning
operator, rather than a professional laborer.
Once again, congratulations to another cleaning professional who will not wait for
tomorrow, and will not have to compete against the RX-20. The competition will
have to try and compete with you!
An Evolution That Had To Happen
Your new RX-20 has been precision engineered to bring you to the state-of-the-art in
carpet cleaning. In the past, a wand technician had to supply all the pressure and
motion to do the cleaning. The RX-20’s weight distribution and rotary motion enable
the technician to maneuver the unit easily with less fatigue and without back strain.
The RX-20’s electric motor drives its precision transmission which, in turn,
rotates the star assembly. Cleaning solution is injected through the center of the
gearbox shaft directly to the five spray jets. Soiled solution is then extracted from the
carpet by five cleaning heads and drawn through the aluminum exhaust manifold to
your cleaning system’s recovery tank.
NOTE: The operating temperature and pressure of the cleaning solution as
well as the vacuum power depends entirely on the type of cleaning
system you use.
Construction
The base, exhaust manifolds, handle, gearbox housing and cleaning heads are all cast
or molded aluminum. Other parts are either metal or high impact plastic.

To prepare your machine for use,
follow these instructions:
a) Remove the machine from the
packaging. Inspect the machine
carefully for any damage that may
have occurred during shipping. If
any oil spillage is noted be sure to
check the gearbox lubricant level
(see instructions).
b) Now attach the star assembly to
the base. Lean the machine back
and rest it on the handle. Thread
the star assembly onto the exposed
shaft remembering to go in a
counter-clockwise direction.
Important: Remove the solid shipping
plug from the top of the gearbox and
replace it with the vented plug provided
before operating the machine.
Your machine is now ready to operate.
Assembly Instructions
If you purchased a High Speed RX-20,
it may require assembling if it was
shipped in two separate boxes.
To assemble:
a) With the three bolts provided,
attach the handle to the base using
a 9/
16" wrench. (see illustration to
below).
b) Next attach the stainless steel hose
to the rotary union using 7 /
16" and
½" wrenches.
c) Next attach the 2" vacuum hose to
the base and handle using the hose
clamps provided.
d) Next plug the male and female
electrical connections together.

Preparation
1. Handle Adjustment: Loosen the
adjustment knob located below the
RX-20 label (turn counter-clockwise
to loosen, clockwise to tighten).
Adjust the handle to a comfortable
height. Several adjustments may
be needed before a desirable oper-
ating position is found.
NOTE: Most technicians have found
better control and less fatigue when
the handle is in a low position just
around the hip line. There is an
ideal position for each person which
will ensure the RX-20 will do the
work instead of you.
2. Solution and Vacuum Hose Hook
ups: Your RX-20 is equipped with
440 male quick connect for the
solution hose hookup and a two
inch OD vacuum hose inlet (refer to
the above illustration). A solution
hose with a 440 female quick
connect is required. The vacuum
inlet requires a two inch ID vacuum
hose for proper air flow with a truck
mounted system.
Operation
IMPORTANT: The vacuum hose must
be in good condition to ensure maxi-
mum airflow. If you do not have a 440
female quick connect and can not find
it locally, it can be ordered from the
HydraMaster Parts Department. Call
[phone] and request part #
052-051 (440 QC).
3a. Electrical Cord Hook Up (Regular
RX-20): The 50 foot electrical cord
on your RX-20 is a detachable
three-prong grounded line requiring
a three-prong, 15 amp receptacle.
A three-prong to two-prong adapter
may be used, providing its ground
wire is properly attached to a
grounded terminal.
-CAUTION -
Do not, under any circumstances, re-
move the ground prong from your RX-
20 power cord. Serious injury or death
may result. To connect the power cord
to the unit, insert the male twist-lock
plug (from the unit) into the female end
(on the power cord) and twist until
they are securely locked together.
3b. Electrical Cord Hook Up (High
Speed RX-20): The 50 foot
electrical cord on your RX-20 is a
permanently attached, three-prong
grounded line requiring a three-
prong, 15 amp receptacle.

To move forward and backward,
position the
handle so that
the unit remains
a stationary, then
push forward or
pull back. To fa-
miliarize yourself
with your RX-20,
practice on an
opencarpet-
ed area. Depress
both the solution
trigger and motor
trigger and move
the RX-20 slowly
in a three to five foot arc, as shown in
Cleaning Patterns on the following page.
-CAUTION -
Do not operate your RX-20 on dry
carpets The friction generated by the
revolving cleaning heads may damage
fibers in the carpet.
Once you have become familiar with the
speed and movement of the machine,
practice making it hover in one spot.
(The hovering maneuver is useful for
removing stubborn stains, as well as
removing furniture indentations.)
Do not tilt machine sideways while mov-
ing forward and backward. A loss of
control may result in damage to the unit
or location.
A three-prong to two-prong adapter
may be used providing its ground
wire is properly attached to a
grounded terminal.
-CAUTION -
Do not, under any circumstances,
remove the ground prong from your
RX-20 power cord. Serious injury or
death may result
Operating Instructions
1. Control Functions: There are
control triggers located on each
side of the handle under the rubber
hand grips. As you operate the RX-
20, the trigger on your right-hand
side controls the electric motor that
drives the cleaning heads. On the
left hand side, the trigger controls
the high pressure solution spray.
The air flows constantly while the
RX-20 is in operation.
2. Maneuvering Your RX-20: Your
RX-20 maneuvers like a rotary floor
machine. To move the RX-20 to
the right, lift the handle slightly.
The more you lift or lower the
handle, the faster the RX-20 will
move.

Cleaning Information
Cleaning Patterns
For regular carpet cleaning use an over-
lapping arc pattern three times over the
same area (two passes with solution and
one pass for drying). When cleaning
carpers, first clean in circular pattern,
then use the overlapping arc pattern to
dry the area.
Note: Dirtiest areas may require two
or more cleaning passes. Using either
pattern, you should develop a comfort-
able rhythm. To obtain maximum per-
formance from your RX-20, move it
slowly and deliberately with a 50% over-
lap, giving it time to clean and extract.
(Unlike a manual wand, the RX-20 is
doing the work you had to do in the
past) A steady pace rather than a fren-
zied one will increase efficiency and
production and decrease fatigue.
The Following Cautions Should
Be Observed While Cleaning:
1. DO NOT operate your RX-20 over
metal floor moldings. Damage to both
the molding and the cleaning head will
result.
2. DO NOT operate your RX-20 on
hardwood floors.
3. DO NOT operate your RX-20 over
loose or unraveled carpet seams.
The cleaning head may catch and
cause further damage.
4. DO NOT operate your RX-20 on
concrete floors. It will develop sharp
edges on the extraction heads that
will damage carpet fibers.
5. DO NOT clean over the edge of a
loose carpet. Instead, clean only up
to the edge. Damage may occur
should the extraction heads catch
the loose carpet.
Special Information
During the cleaning of some plush car-
pets you may notice a “pilling” effect.
With an RX-20, loose yarns form balls
and are kicked aside as the cleaning
heads revolve. This is normal when ag-
gressive cleaning or even normal vacu-
uming takes place, as evidenced by a
number of dead, loose yarns in the
vacuum cleaner bag. These loose yarns,
in most cases, are short staple yarns or
filler yarns used to give the carpet a
denser appearance. Because your RX-
20 weighs approximately 90 pounds and
rests on five four-inch cleaning heads,
the yarns are not sucked up into the
vacuum heads as they are with a
vacuum cleaner or old-style cleaning
wand.

-CAUTION -
On older, rubberbacked, glued down car-
pets that may be delaminating with age,
the RX-20 may cause further delamina-
tion. When in doubt, DO NOT use your
RX20.
Cleaning Hints
A. Most cleaners customarily clean their
way out of an area or room. With
the RX-20, it is possible to clean into
an area or room, as shown in the
illustration below, so that the hoses
are dragged behind you during the
cleaning process rather than kicked
out of the way as you back out of
an area. The “cleaning into” method
works especially well in hallways or
confined areas
B. The RX-20 is a very aggressive
carpet cleaning power head and will
leave the carpet with a freshly-
cleaned appearance. The carpet
should be brushed or groomed after
the cleaning process to remove any
swirl marks left behind.
The RX-20 has been very successful in
restoring badly matted traffic lanes in
front of doorways and sofas. Even pivot
areas can be brought back to life again,
in most cases. “Cornrowing” in hall-
ways can also be eliminated with mini-
mal effort.

Machine Maintenance
4. Remove the in-line solution filter
screen by unscrewing the 7
/
8inch
hex nut protruding from the back of
the handle. Rinse under water to
remove debris. If necessary, use a
toothbrush to remove stubborn
particles.
5. Check the jet spray for evenness.
An uneven spray will cause im-
proper flow of the cleaning solution.
6. Remove the cleaning head. It
unscrews in the same direction it
turns during operation (or clockwise
when looking at it from the under
side). Once you have loosened the
Good care and regular maintenance of
your RX-20 will result in a long, depend-
able life for the unit. Keep in mind that
your RX-20 will be in full view of your
customer. An RX-20 that is dirty and
unkempt in appearance can cause your
image to suffer. You are offering your
customer the latest in cleaning technol-
ogy. Therefore, it is important that your
company image reflect your desire to
give your customer THE BEST.
The surface finish on your RX-20 is a
durable, baked on epoxy coating and is
easily cleaned with a damp cloth. To
further protect the finish, a light coat of
good silicon base polish should be ap-
plied periodically.
Lubrication and maintenance play a key
role in the life of your RX-20. Hence,
the following daily and periodic mainte-
nance steps must be followed. Train
yourself to maintain your unit on a regu-
lar schedule until it becomes habitual.
Daily Maintenance
1. Inspect the power cord for cuts,
breaks, etc. Repair as needed.
2. Inspect the vacuum hoses for
breaks or tears. Repair or replace
as necessary.
3. Visually inspect your RX-20 for
water leaks, damage to the clean-
ing heads, etc. Repair as necessary.

30 weight SAE motor oil. Also, put
a few drops into the hub threads.
9. Coat the shaft with Pennz-Guard or
a similar lubricant. Reinstall the
vacuum head assembly onto the
shaft by rotating it counter-clock-
wise.
IMPORTANT: While rotating the
vacuum head assembly in the counter-
clock wise position, make sure that it
spins freely all the way down. If it
begins to require the slightest finger tip
pressure, unscrew it and brush off the
threads. All it takes is the slightest grain
of dirt or sand to obstruct the threads.
If you turn too far onto a grain of dirt,
the hub may become locked onto the
shaft of the gearbox.
assembly, spin it
off with your
hands. If the clean-
ing head is difficult
to remove, you may
use a ¾ inch socket
wrench on the ex-
posed center nut.
To prevent the gearbox from turning,
the output shaft will accept a 5/
8 inch
wrench just below the rotary union.
Wash the cleaning heads and shroud
assembly with a garden hose, being
careful not to wet the electric motor
assembly. Clean any lint buildup from
the cleaning heads and vacuum hoses
(lint buildup will restrict proper airflow
and prolong drying time).
-CAUTION -
7. Clean off any debris that may have
accumulated on the gearbox shaft or the
inside threaded bore of the hub. An
accumulation of debris here, if not re-
moved, may damage the gearbox oil
seal. This will result in loss of oil in the
gearbox. If the gearbox is operated with-
out oil, severe damage may occur.
8. Lubricate the felt vacuum seal on
top of the hub with a quality,

Transport and/or Storage
Whenever your RX-20 is transported or
stored, it is recommended that the clean-
ing head be removed. The machine will
then sit flat on the floor and remain more
stable, especially during transport.
Freeze Warning and Protection
Your RX-20 can sustain damage from
freezing, as can any equipment that
functions with the use of water. Care
must be taken to protect this tool from
freezing just as you do your other equip-
ment. To protect it from freezing, sim-
ply blow air from a gas station air hose
through the solution quick connect with
the valve open. This will blow all water
from the valve, solution line, rotary union
and jet assembly. Open and close the
valve several times to ensure that all
water is removed.
Parts and Assemblies
HydraMaster has every part in stock. For
parts ordering or servicing call:
Parts Department at [phone] or
Service Department at [phone]
Check for a registered HydraMaster
Service Center in your area.
Periodic Maintenance
Regular RX-20 only:
Check the oil in the gearbox. The
unit must be on a level surface to
get an accurate reading. Change
the oil in the gearbox every 100
hours. Use 80-90 weight gear oil to
reduce friction and allow the gear
box to run at a cooler temperature.
With the unit level, drain the oil. Next
fill the gearbox with new oil at the
oil port on the front until it dribbles
out of the inspection port.
NOTE: Normal wear and tear on your
new gearbox will cause small amounts
of metal splinters to rub loose during
the first 10 hours of use. Therefore,
we recommend that you change the oil
after 10 hours, and after that every 100
hours.
High speed RX-20:
Check the oil the gearbox. Check
the oil level in the gearbox on a
monthly basis. This is a permanently
lubricated gearbox. You do not need
to change the oil. However, main-
taining the proper oil level is impor-
tant. To check the oil level, remove
the vent plug and look into the gear
box. Turn the star until you can see
the inspection hole in the gear. With
the RX-20 sitting flat on a table or
the floor, the oil level should be up
to, but not above, the middle of the
gear. If oil needs to be added, use a
quality 80-90 weight gear oil.
NOTE: When checking the oil level in
the gearbox, you can use a toothpick as
a dip stick. The oil level should read
3/8th of an inch.

Repair
High Pressure Valve Assembly:
The valve assembly’s moving parts will
eventually wear out it time. Its repair or
replacement is a relatively simple
operation.
1. Remove the 440 male quick connect
(A) with a wrench.
2. Remove the five Allen head screws
(B) in the back plate on the handle
and lift the back panel off.
3. Disconnect the stainless steel hose
(C) from the bottom of the valve
assembly.
4. Remove the bolt (D) holding the trigger.
5. Remove the two bolts (E) holding the
valve assembly in the handle and pull
out.
6. The valve may now be rebuilt or re-
placed.
-CAUTION -
If the valve has been frozen, inspect it for
leakage before reinstalling the back plate.
Removal of Components
Felt Vacuum Seal Replacement:
A worn or unlubricated seal will not form
a proper seal. Lack of a proper seal will
impair the vacuuming capabilities of the
unit and therefore leave behind more
water in the carpet than is desirable.
First, remove the vacuum head assembly
as previously described. Using a pocket
knife, carefully pry the seal up and lift it
out. If the seal appears worn or glazed
so that it will not lubricate well, try turning
it over. If that does not work, or if it is
damaged, replace it with a new one. We
recommend changing the felt seal after
10 hours of use. Replace it with a spare,
soaked seal. Press
the seal in place
and saturate it with
a quality 30 weight
SAE motor oil.
Always place the
flattened, used seal
in an oil bath to
rejuvenate.
NOTE: A tuna fish
can is the right size and shape and does
not require a large amount of oil.) This
seal and its condition
play an important part in the optimum
performance of your RX-20.
