Some models have a "check bag" indicator on the
outside of the bag door. Fig, 4

The cleaning tool hose attaches to the cleaner
through the top of the hood and CAN stay attached

at all times.

When using cleaning tools, the nozzle control must
be in the #5 cleaning tools position. Fig, 5

Withthe nozzle control inthe number 5 position, a
valve gate in the main body closes and blocks all air
flow from the agitator cavity therefore diverting it to
the hose.

Set on carpet, positions 1-4, the gate valve is
opened allowing air to flow from the agitator cavity
to the motor. Fig, 6

To ensure maximum efficiency in the 4 floor cleaning

positions .b_o_Lb_hose ends must be firmly connected

to the cleaner base and tool rack Fig, 7 or the hose

removed completely and the tool door closed.

Refer to the Hoover Service Manual for repair proce

Note;

Only the components that

distinguish the Dirt Finder
unit from the Dimension
are listed.

I. General

These uprights are lightweight upright vacuums
that feature high performance computer design
motors, double edge cleaning, quick release cord

wraps and top conversion cleaning tools

All models have automatic height adjustment in
that the nozzle is free to float up and down on the
carpet. These models additionally have front
wheel height control to limit the minimum nozzle

height which allows the user to "select the proper
setting for optimum operation on various types of

carpets.

The Legacy and Legacy II models use Type "A"
top-fill disposable bags.

The Dimension/Dirt Finder uses Type "Z" top-fill
disposable bags.

Microfiltration bags are available for both models.

II. Operation

These cleaners operate on a Dirty Air System
principle, i.e., dirty air passes through the motor

area (fan) before reaching the bag.

=o CLEAN AIR

,o DIRTY AIR

As illustrated, air and dirt are sucked through the
molded agitator housing and directed into the
motor area. The fan then propels the air and dirt
up the handle passage and into the throw-away
bag.

The Legacy units are controlled by an on/off switch
located on the side of the unit. (Fig. A)

The Legacy II, Dimension and Dirt Finder units are
controlled by an on/off switch located in the front of

the upper handle. (Fig. B)

The carpet height adjustment lever has four
settings for carpet cleaning and one for the top too!

NOZZLE CONTROL
KNOB _,_

It is important that the unit be in the proper setting
(carpet - for floor cleaning, and cleaning tools -

when using the hose and tools). This will ensure

optimum performance.

The cleaning tool hose attaches to the unit through

the tool door located on the top of the hood. The
air is directed to the hose by adjusting the nozzle

control knob to the cleaning tool position.

The valve gate operates in conjunction with the
height adjustment lever. When the lever is in any
one of the four carpet settings the valve gate is

open. The cam is not contacting the valve gate.

Note: These illustrations are shown without the

bottom plate or wheel assembly in place.

Dirt Finder feature:

The embedded Dirt Finder system is powered by a
regular 9V alkaline battery. The battery is located
in a holder inside the bag compartment.

The circuitryis energized when the cleaner on/off
switch is tumed to the on position. A separate

switch mounted in the bag housing is actuated by

a raised rib on the upper switch rod.

A microphone, located near dirt duct, senses
debris that strikes the tube and signals the circuit

board which controls the lights.

The green light signifies clean and the red dirty.

It is important to note that when you turn on the

unit the red light will come on. After a few seconds
the rod light will go off and the green light will come
on. This function lets you know the Dirt Finder
feature is ready. If this lighting pattern does not

occur check the troubleshooting portion of this

:instruction.

1. 9V battery not installed.

2. Low battery.

3. Battery disconnected.

4. Switch failed.

5. Switch out of position.

6. Wires not connected at switch or

Note: Normal lighting pattern is discussed in the basic operation section of this
instruction

B. Light does not

change from
green to red

during normal
operation

1. Carpet clean. 1. The red light may seldom come on during
cleaning. This means your cleaner is picking up

primarily fine surface dust and lint which the
system may not detect or that the carpet is clean.

Switch unit to Hi - sensitivity and recheck.

Note: To check lighting pattern, unplug unit, turn cleaner switch to on (green light will

illuminate). Tap inside the opening of the dirt duct with a screwdriver. The light
should change from green to red. If the light does not change, check the following.

1. Microphone out of position.

2. Dirt duct opening "caked with

dirt"

3. Microphone leads disconnected
from circuit board.

4. Microphone failed.

1. Check to insure the mic is firmly pressed into
the seat.

2. Clean opening and recheck.

3. Check and reconnect.

4. Replace microphone (Check 1 - 3 first).
