Grounding Instructions
This appliance must be grounded. If it should malfunction or breakdown, grounding provides a
path of least resistance for electric current to reduce the risk of electric shock. This appliance
is equipped with a cord having an equipment grounding conductor and grounding plug. The
plug must be inserted into an appropriate outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
WARNING
Improper connection of equipment-grounding conductor can result in a risk of electric shock.
Check with a qualied 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 appliance—if it will not
t the outlet, have a proper outlet installed by a qualied electrician. This appliance is for use
on a nominal 120-volt circuit and has a grounded plug that looks like the plug illustrated in
Figure A. Make sure that the appliance is connected to an outlet having the same conguration
as the plug. No adapter should be used with this appliance.

Cleaning With Your Rug Doctor Machine And Products
Read all instructions completely before you begin. To assure proper results, test carpets and
upholstery for colorfastness. Wet an inconspicuous area with a small amount of cleaner.
After 1–2 minutes, blot with a white paper towel and check for color transfer. Follow these
additional guidelines when cleaning with your Rug Doctor machine:
• Rug Doctor machines and Rug Doctor cleaning products are safe for most carpets. However, you risk damage
to carpets and hard oor surfaces not intended for water extraction method cleaning. Do not use the Rug Doctor
machine or cleaning products on natural ber oriental rugs (silk or wool), hand-loomed wool rugs, braided rugs,
sisal or jute carpets; hardwood or laminate ooring. Some stains require professional treatment. Use cool water
when cleaning wool, wool blends or delicate bers.
• Rug Doctor machines and Rug Doctor cleaning products are safe for many fabrics, even delicate bers. However, you
risk damage to fabrics not intended for water extraction method cleaning. Do not use Rug Doctor machines or
products to clean fabric with cleaning codes S or X, silk, Haitian cotton, velour, brushed corduroy, leather or non-
colorfast fabrics, mattresses or mattress toppers made with memory foam, foam or goose down. Some stains
require professional treatment. Use cool water when cleaning wool, wool blends or delicate bers.
• The machine was designed for use on carpet and upholstery applications in accordance with the instructions and
recommendations in this manual. If you use the Rug Doctor machine to clean surfaces other than carpet and
upholstery, such as hard surface oors, use only Rug Doctor recommended products. Rug Doctor Oxy-Steam® Carpet
Cleaner can be safely and effectively used for either carpeting or water-safe hard surface oor coverings.
• Do NOT put bleach, dye or products other than Rug Doctor cleaners in this machine. Use of inappropriate products
may cause this machine to malfunction and may result in carpet or machine damage.
• Foam should never be ingested through the dome lter. Damage to the carpet and/or vacuum motor could result.
• To Reduce the Risk of Fire and Electric Shock due to internal component damage, use only Rug Doctor®
cleaning products intended for use with this appliance. See the Cleaning Product section of this manual.
An de réduire les risques d’incendie et de décharge électrique provoqués par des composants internes endommagés,
utilisez uniquement les produits de nettoyage Rug Doctor conçus pour ce produit. Lire la section consacrée aux
produits de nettoyage dans le présent manuel.
• Avoid picking up hard or sharp objects with the carpet cleaning machine. They may damage the machine. Do not
use the machine for dry vacuuming because this machine does not have a ne dust lter. Dry vacuuming damages the
vacuum motor.
• Do not use the machine to vacuum large quantities of liquid, such as a ooded basement or large spill. This machine is
not equipped with an automatic overow shutoff.
• To avoid damage, do not place the machine or hand tool on hardwood or laminate ooring or allow any solution or
overspray to contact such ooring.
• To avoid pump damage, do not continue to press the spray (pump) switch when the solution tank is empty.
Read instructions carefully. Rug Doctor, Inc. is not responsible for damage due to misuse of this machine.
Carpet Cleaning Tips For Best Results
• Treating difcult spots. Rug Doctor machines are designed to deep clean and extract in one cleaning pass. Your best
choice for cleaning difcult spots, stains or trafc areas is to use Rug Doctor’s specialty products: Hi-Trafc Pre-
Treatment, Spot & Stain Remover, Urine Eliminator, or Odor Remover.
• Avoid over-wetting your carpet. Don’t go over a heavily-soiled spot more than 2 times. Berber, Multi-Level or Looped
carpets retain more liquid. For these types of carpets, DO NOT repeat cleaning passes. If additional cleaning is desired,
allow carpets to dry before attempting to reclean heavily-soiled areas. Because they retain more liquid, Berber carpets
that are overwet can experience “wick up” of soils or spills very deeply embedded in the carpet or backing. If you
experience this problem, allow area to dry completely then clean again using single, quick passes (1-2 feet per second).
• Cleaning Berber carpet; You can use your Rug Doctor machine to clean Berber carpet. For best results, make only
one pass while depressing the thumb switch to release solution. Make a second pass over the same area without
pressing the switch so that you are only vacuuming the liquid. Make sure the vacuum slot at the front bottom edge
of the machine is snug against the carpet.
• Overlap passes slightly to cover all areas. IMPORTANT: When pressing the red button, keep machine moving so
vibrating brush does not agitate in one place.
• Liquid recovery. You should recover 70 - 80% of the liquid used depending on your carpet type. With Berber carpet, you
may recover a little less liquid.
• Avoid excessive foam in the recovery tank, which can be expelled through the machine and may affect your carpet. If
foaming occurs turn off the machine and empty the upper white tank if it is full.
• If you replace furniture before the carpet is completely dry, place aluminum foil under furniture legs to prevent stains.
Leave aluminum foil under furniture legs until carpet is completely dry.
• For faster drying, ventilate area. Open doors and windows. Place fans pointed downward on carpet. Turn on heat in
damp or cold weather. Turn on air conditioner in humid or hot weather. This is highly recommended when cleaning
Berber carpets.

Before You Begin
Review machine safety warnings found in
the front of this manual. Using a normal dry
vacuum cleaner, vacuum the area you want
to clean to remove loose dirt before using
the Rug Doctor machine. This will help
keep the brushes and water vacuum system
working efciently. Pre-treat any special
problem areas with appropriate Rug Doctor
solutions. For example, use Urine Eliminator
on tough pet stains and other bio-origin
stains.
Set Up
Check the back of the machine to ensure
hose connections are secure and set to
clean carpet instead of upholstery (ILLUS.1)
Lift up on the recovery latch and raise dome
hood (ILLUS.2). Remove the recovery tank.
Depending on how dirty your carpets are,
add 2oz- 4oz (1/4 to 1/2) cup of Rug Doctor
Oxy-Steam® Carpet Cleaner product per
gallon of hot tap water in a clean bucket
(ILLUS.3). Use caution to insure water is not
so hot as to scald or burn skin.
The lower tank capacity for the Rug Doctor
Mighty Pro X3™ is 3 gallons. Fill the lower
tank with the Rug Doctor Oxy-Steam®
Cleaning solution by pouring through the
white lter screen. Machine is full when
liquid halfway covers the lter screen
(ILLUS.4). Replace recovery tank and close
the dome hood (ILLUS.2).
Plug in the power cord and position the
machine. Refer to the label on the side of
the handle. Slide the switch to the “Carpet”
position for carpet cleaning (ILLUS.5).

Start Cleaning
While depressing the press for spray red button
on the top of the handle (ILLUS.6), pull the
machine slowly and steadily backward in a
straight line, keeping vacuum slot against the
carpet surface. On lightly soiled carpets you can
pull the machine quickly at one foot per second.
For moderately, or heavily soiled carpets, pull
the machine at approximately one foot every two
seconds. You will begin to see soiled solution
entering the clear dome. (If you don’t, stop and
refer to the Troubleshooting section).
IMPORTANT: When depressing the press for
spray red button, keep machine moving so the
vibrating brush does not agitate in one place
(ILLUS.7).
Release the red button 6 to 12 inches before
ending each pass to stop cleaning solution. Tilt
machine back and push it forward to start a new
backward cleaning pass (ILLUS.8).
Continue cleaning in this manner, overlapping
each pass slightly. When the lower tank runs
out of cleaning solution, the pump sound will
increase in volume slightly and dirty water will
stop entering the dome. Switch the machine to
“0” for the off position. Remove and empty the
recovery tank by pouring dirty solution into a
toilet or outdoors (ILLUS.9).
Rinse the recovery tank and rell the lower tank
with clean solution/water mixture using a clean
bucket. If you are near the end of your cleaning
job, ll the lower tank half full so it empties by
the end of your job. Replace the recovery tank.
Continue the cleaning process until area to be
cleaned is covered. When cleaning is complete,
switch the machine to “0” for the off position. To
drain and clean the machine, please refer to the
Maintaining Your Rug Doctor Machine section.
