Tools And Automatic Tool
Conversion
SteamVacs with the automatic tool conversion
feature were first introduced in mid-1997. Fig. 1
Characteristics of the three types:
Supreme: No rotating brushes
Deluxe: Five rotating brushes (for carpet only).
Ultra: Five rotating brushes for carpet and a
powered hand nozzle for upholstery.
These are the third generation of Steam Vats made

ELECTRICAL SYSTEM
TURBINE _-
BRUSIt BLOCK
Deluxe and Ultra models have 5 mlcllocking rotating
brushes. Fig. 6
Tile brushes are driven by an air pOWeled turbine
Fig. 7
Rotation of tile brush can be viewed though a cleai
cover on the hood. The Speed of the brush depends
on air flow and is adjustable for Lo or Hi rotation or
can be turned off completely as might be desired
when cleaning bare floors. Fig. 8
There are 3 major systems in Steam Vacs:
1. Electrical
2. Distribution
3. Recovery
The Electrical System - Fig. 9 consists of the
power supply cord, motor and on/off switch. Close
the switch, the motor runs and provides suction for
recovery at the floor or the upholstery tool. It also
generates air flow to drive the turbine to rotate the
brushes at the floor and in the powere d wand plus
drive the pump to force solution to the upholstery
tool.

I. General
The SteamVac TM with Automated Tool
Conversion is a self contained extractor designed
for deep cleaning of carpet and rugs
These models feature the Automated Tool
Conversion actuated by the handle movement.
Mid line models include 5 rotating brushes for
carpet and bare floor agitation. While top end
models also include an air driven hand nozzle.
This instruction deals with top of the line models.
Instructions that pertain to low end models will be
noted.
II. Operation
The units are controlled by the on/off pedal
located on the LH. side.
then drawn up through the valve and into the
recovery tank where the air and water are
separated, A float and foam filter prevent the
recovery tank from being overfilled.
The pump operates on the suction from the
motor. Suction is directed to the pump through
the pump duct (an integral part of the mainbody),
and is completed at the valve which is actuated
by raising the handle into the upright position.
The pump has a constant flow of solution from
the solution tank through the reservoir assembly.
The five rotating brushes are driven by a turbine,
which operates on the suction from the motor.
The recovery tank can be unlatched by rotating
the handle 90° and lifting out of position. To
empty tank continue rotating handle an additional
90° and lift lid from tank.
ON/OFF
PEDAL
Solution is gravity fed to the floor from the
solution tank through the reservoir assembly to
the distributor/brushes.
ROTATING
BRUSHES
CLEAN SOLUTION
The reservoir is opened by actuating the trigger
in the handle.
The Automatic Tool Conversion uses a valve
which diverts the suction from the nozzle to the
hose when the handle is placed in the upright
position.
III. Disassembly
A. Solution Tank
