Special Features of your BISSELL ProHeat®Pro-Tech®
The ProHeat Pro-Tech is a home cleaning system that automatically
mixes hot tap water with Fiber Cleansing Formula and heats the 
solution as it is applied to the carpet. The combination of heated
cleaning solution, powered brush and suction provide a safe and 
effective method of cleaning.
Temperature control automatically heats the cleaning solution 
as it is being applied to the carpet (*) to safely optimize 
cleaning effectiveness.
The Power Switch controls power to the machine; both
switches must be ON for SmartTemp to work.
The SmartTemp Switch is found on the back of the handle
next to the Power Switch. You may choose not to use the
SmartTemp feature if you are cleaning delicate wool or 
oriental rugs.
*SmartTemp heats the cleaning solution for carpet
and bare floor application only. It does not heat
solution sprayed through the accessory tools.
The SmartTemp Ready Light indicates when the heater is
ON. The heater should be turned on two minutes before
cleaning, to become fully warmed up and ready to clean. It
is found on the front of the handle where it is easy to see
while you clean.
SmartTemp increases the water temperature approximately
25° and will not allow it to exceed 180.°
Provides custom control for each cleaning job.
Lift the SmartMix concentrate bottle up and out of the 
machine base.
Turn the bottle over so that the valve cap is in an upward 
position. Unscrew the valve cap and fill the bottle to the
mark with BISSELL Fiber Cleansing Formula.
Replace the valve cap turning until snug.

SmartMix 
Replace SmartMix concentrate bottle.
Note: If bottle leaks, check for proper 
positioning of o-ring and straw.
Choose the SmartMix setting that fits the cleaning job.
Water Rinse / Carpet Protector- use for gentle
cleaning or for the final rinse after cleaning. This
setting must also be used when applying the carpet
protectant through the applicator, to prevent the
pump from temporarily losing its prime.
Normal- automatically provides the best mix of
water and concentrate for most cleaning jobs.
High Traffic- automatically mixes the right amount
of water and concentrate to dissolve tough grime
and heavy soil. Note: Residual cleaning materials left
in carpet from other products may cause excessive
foaming when picked up. If foam is overflowing
tank, move SmartMix dial to “Water Only” position
until the condition stops.
Note: Both the SmartMix Bottle and the clean
water tank must have liquid in them in
order for the machine to spray. If one tank
is empty, the machine will temporarily
lose its prime and not apply either 
cleaning solution or water only.
Important:
If you are using the WATER RINSE /
CARPET PROTECTANTsetting, fill the Smart
Mix bottle with water also!
The powered brush roll at the floor nozzle is designed to
enhance cleaning performance. The bristle pattern lifts out the
deep down dirt while gently grooming carpet fibers. The floating
suspension self-adjusts to all carpet heights and protects 
your carpet if you leave the power switch ON. When the
machine handle is in the fully upright position, Carpet Saver
™
automatically raises the brush off the carpet.
Our Tank-in-Tank system is designed with a bladder inside for
clean water. As you clean, the bladder will empty. Dirty water
collects in the tank outside the bladder.
Step on handle release to lay the machine handle 
down out of the way.

ance and void 
warranty. Chemical spot
cleaners or solvent based
soil removers should not

may react with the plastic
materials used in your

Tank-in-Tank Continued
Lift the Tank-in-Tank handle. The handle locks the 
lid in place.
Carry it like a bucket to fill at the sink.
Note: You may notice hair and debris deposits on
the carpet that were loosened by the
brushing action (especially with newer
carpets that have never been deep cleaned
before). This debris should be picked up
and thrown away. Debris that deposits in
the Brush Belt should be cleaned between
uses to keep the Belts running free.
Set the tank down and rotate the handle forward to
unlatch the lid. Lift off and set the lid aside.
Find the mouth of the Bladder and fill to the bottom of
the neck with clean hot tap water.*Do not boil or
microwave water as it can destroy the Bladder.
Note: Fill the Bladder with clean hot tap water only.
Replace the tank lid matching the lid and tank edges.
Handle must be in the forward position to reinstall.
Rotate the handle to the carrying position to re-latch 
the lid.
Replace tank in machine base, seating firmly in place.
Rotate handle back down to the latched position.
Note: Both the SmartMix Bottle and the clean
water tank must have liquid in them in
order for the machine to spray. If one tank
is empty the machine will not apply either
cleaning solution or water only.
Important: If you are using the WATER RINSE /
CARPET PROTECTANTsetting, fill the Smart
Mix bottle with water also!
Remove the Tank-in-Tank – follow steps 1 and 2 
on page 7 and 8.
Carry the Tank-in-Tank, like a bucket, to the sink where

final cleanup.
The Flow Indicator is located on the machine base. It spins when
the trigger is pressed to indicate that the machine is applying 
cleaning solution to the floor. It will stop spinning to indicate that the
SmartMix bottle or bladder needs to be refilled, or when the trigger
is released. Flow Indicator does not spin when set to Tool setting.
This provides above floor cleaning with the flip of a switch.
Just choose the cleaning tool or protector applicator, attach 
to the flex hose and ProHeat Pro-Tech is ready to clean 
upholstery, stairs or apply extra protection against dirt and
tough stains when using the Scotchgard protector applicator.*
*Set the dial to Floor Cleaning when cleaning
carpets or bare floors or set it to Tools/PreTreat
when using the flex hose attachments or for 
pre-treating floors, or when applying the
Scotchgard protector applicator.
*SmartTemp heats the cleaning solution for carpet
and bare floor application only. It does not heat

Plan activities to give carpet time to dry.
Remove easily moved furniture from the room (chairs,
lamps, coffee tables, etc).

to begin cleaning in the corner farthest from your exit.
Set up the machine following instructions in

effectiveness for heavily soiled carpet, high traffic 
areas such as entryways and hallways, or stairs.
Set the SmartMix dial to High Traffic.
Set ReadyTools dial to PreTreat.
Plug into a proper outlet and turn ON both the Power
and SmartTemp switches.
While pressing the trigger, slowly make several passes
over the area to be cleaned.Caution: Do not overwet.
