READ ALL INSTRUCTIONS BEFORE USING THIS APPLIANCE
Warning: To reduce the risk of fire, electric shock, or injury:
• Do not use outdoors or on wet surfaces.
• Connect to a suitable extension cord. See “Extension cord instructions”.
• Connect to a properly grounded outlet only. See “Grounding Instructions”.
• Close supervision is necessary when any appliance is used by or near children.
Do not allow vacuum cleaner to be used as a toy or to run unattended at any time.
• Keep hair, loose clothing, fingers, feet and all parts of body away from openings,
rotating agitator and other moving parts. Do not operate cleaner in bare feet or
when wearing open toe shoes or sandals.
• Do not pick up anything that is burning or smoking, such as cigarettes, matches, or
hot ashes.
• Do not use to pick up flammable or combustible materials such as gasoline or fine
wood sandings or use in areas where they may be present.
• Avoid picking up hard, sharp objects with the cleaner. They may damage the
cleaner.
• Always turn off this appliance before connecting or disconnecting hose.
• Do not use without dirt cup or filters in place. Empty dirt cup and clean filters frequently when picking up very fine materials such as powder.
• Use extra care when cleaning on stairs.
• Do not put any object into openings. Do not use with any opening blocked; keep
free of dust, lint, hair, or anything that may reduce air flow.
• Do not pull or carry by cord, use cord as a handle, close door on cord or pull cord
around sharp edges or corners. Do not run appliance over cord. Keep cord away
from heated surfaces.
• Always disconnect cord from electrical outlet before servicing the cleaner.
• Unplug cleaner when not in use. Turn off all controls before unplugging.
• Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord. Never
handle plug or appliance with wet hands.
• Do not use with damaged cord or plug. If appliance is not working as it should, has
been dropped, damaged, left outdoors, or dropped into water, take it to a Hoover
Factory Service Center or Authorized Hoover Warranty Service Dealer (Depot).

before operating
cleaner
Operate cleaner only at voltage
specified on data plate on bottom of

Warning: Electrical shock could
occur if used outdoors or on wet
surfaces.
Grounding
instructions
This appliance must be grounded. If it
should malfunction or breakdown,
grounding provides a path of least resistance for electrical current to reduce the
risk of electric shock. This appliance is
equipped with a cord having an equipment-grounding conductor (C) and
grounding plug (A) (Fig. 1-2). The plug
must be plugged into an appropriate
extension cord and outlet (B) that is
properly installed and grounded in
accordance with all local codes and
ordinances.

DANGER -
Improper connection of the equipment
grounding conductor can result in the
risk of electric shock. Check with a qualified electrician or service person if you
are in doubt as to whether the outlet is
properly grounded. Do not modify the
plug or extension cord provided with the
appliance - if it will not fit the outlet, have
a proper outlet installed by a qualified
electrician. This appliance is for use on
a nominal 120 volt circuit and has a
grounding plug that looks like the plug
illustrated in sketch (A).
A temporary adapter (D) may be used to
connect this plug to a 2-pole receptacle
(E) if a properly grounded outlet is not
available. The temporary adapter should
be used only until a properly grounded
outlet (B) can be installed by a qualified
electrician.
The green colored rigid ear, lug, or the
like (F) extending from the adapter must
be connected to a permanent ground
(G) such as a properly grounded outlet
box cover. Whenever the adapter is
used, it must be held in place by a metal
screw.
Note: In Canada, the use of a temporary adapter is not permitted by the
Canadian Electrical Code.

cords or plugs.
When servicing, refer to a qualified
electrician or service person only. Use

Stair cleaning
A stair cleaning handle has been
designed for ease in using your cleaner
on stairs. With handle in operating position, place fingers under edge of stair
cleaning handle and guide cleaner with
other hand on upper handle.
As an alternative, you may use the hose
and furniture nozzle for stair cleaning.
Clean from bottom to top.
When using cleaning tools, the agitator will continue to rotate.
CAUTION: To avoid personal injury or
unnecessary wear to carpet, and to
prevent the cleaner from falling,
always place it at the bottom of the
stairs.
Settings
For maximum cleaning performance,
the following carpet height settings are
recommended.
• Low setting: for all types of carpet and
hard floors.
Note: If the cleaner is difficult to push,
rotate knob to the next higher setting.
• Medium and High settings: for deeper
pile carpet where easier pushing effort is
desired, while maintaining good cleaning
performance.
Cleaning lightweight
flexible rugs
Stand on one end of rug and move
cleaner toward other end or edge.
Before reaching edge, push down on
handle. This will lift up the nozzle (front
of cleaner) as shown and will prevent
rug from clinging to cleaner. Continue to
lift up nozzle so that when you have
reached the edge, it is completely off
the rug. Move cleaner back to start
again, lower nozzle, and use only forward strokes.
Carpet height
adjustment
The cleaning of carpet and rugs takes
place at the nozzle (D).
When it is necessary to raise and lower the
nozzle for various carpet pile heights, turn
the carpet height adjustment knob (E) to
the desired setting.
For ease in turning the knob, place handle
in upright position.
Nozzle won’t move to adjusted position
until handle is lowered to operating
position.

described in “How to empty dirt cup”
should sufficiently remove dust and fine
particles from the HEPA filter and pre-filter.
The filter assembly can also be removed
for additional cleaning.
3. Maintenance
When to empty
It is recommended that the dirt cup be
emptied before the dirt reaches the dirt
inlet opening on back of dirt cup (Fig. 3-
1) or after every use if preferred.
CAUTION: Very fine materials, such
as face powder or cornstarch, may
seal the filter and cause loss of suction. When using the cleaner for this
type of dust, empty the cup and clean
the filters often.
How to empty
Turn cleaner off and allow motor to
stop completely.
Disconnect cleaner from electrical
outlet. Do not use the cleaner without
dirt cup or filters in place.
Press dirt cup latch (F) and remove dirt
cup.
Familiarize yourself with these home
maintenance tasks as proper use and
care of your cleaner will ensure continued cleaning effectiveness.
Dirt cup
The dirt cup assembly consists of the
following parts:
Lid (A)
Dirt cup (B)
Pre-filter (C)
HEPA cartridge filter (D)
Dirt inlet opening (E)
While the cleaner is in operation, the pre-
filter screen will stop larger debris from
entering the HEPA cartridge filter chamber.
This larger debris will be seen collecting in
the left side of the dirt cup. The HEPA cartridge filter will collect fine particles that
have passed through the pre-filter screen.
