Central Vacuum Rugmaster Sweep n Groom Powerhead






When using an electric appliance, basic precautions should always be followed, including the following:


Read all instructions before using this vacuum cleaner.





To reduce the risk of fire, electric shock, or injury:


Do not use outdoors or on wet surfaces.

Do not leave vacuum cleaner when plugged in. Remove from inlet valve and unplug the electrical cord when not in use and before servicing.

Do not allow to be used as a toy. Close attention is necessary when used by or near children.

Use only as described in this manual. Use only manufacturer's recommended attachments.

Some hoses contain electrical wires. Do not use if damaged, cut or punctured. Avoid picking up sharp objects.

Always turn off this appliance before connecting or disconnecting either hose or motorized nozzle.

Do not use with damaged cord or plug.  If vacuum cleaner is not working as it should, has been dropped, damaged, left outdoors, or dropped into water, return it to a service center.

Do not pull or carry by the cord, use the cord as a handle, close a door on the cord or pull the cord around sharp edges or corners.  Keep the cord away from heated surfaces. Do not run the appliance over the cord.

Do not use extension cords or outlets with inadequate current carrying capacity.

Turn off all controls before unplugging.

Do not unplug by pulling on the cord.  To unplug, grasp the plug, not the cord.

Do not handle plug or vacuum cleaner with wet hands.

Do not put any objects into openings. Do not use with any openings blocked; keep free of dust, lint, hair, and anything that may reduce air flow.

This vacuum creates suction and some contain a revolving brush roll.  Keep hair, loose clothing, fingers, and all parts of body away from openings and moving parts.

Do not place cleaner on furniture as brush roll may damage the furniture. Place cleaner on floor with handle in storage position while using attachments.

Do not pick up anything that is burning or smoking, such as cigarettes, matches, or hot ashes.

Do not use without dust bag or filter(s) in place.

Belt pulley can become hot during normal use. To prevent burns, avoid touching the belt pulley when servicing the drive belt.

Use extra care when cleaning on stairs.

Do not pick up flammable or combustible liquids, such as gasoline, or use in areas where they may be present.

Store your cleaner indoors in a cool, dry area.

Keep your work area well lighted.

Unplug electrical appliance before vacuuming them.





The powerhead is designed to pick up dirt and dust particles. Avoid picking up hard or sharp objects with the powerhead to prevent bag tears, hose clogs, and fan blade breakage with subsequent motor damage.


DO NOT OIL.  The motor in your Powerhead is permanently lubricated and sealed. Do not oil the motor at any time.

Rating Plate

The model, type and serial numbers are indicated on the rating plate. For prompt and complete service information, always refer to these numbers when inquiring about service.

Straight Extension Wands

The two extension wands can be used individually or fitted together to increase the cleaning reach and permit comfortable stand-up floor cleaning.


Your motor driven powehead uses a belt to transfer power from electric motor to the revolving brush roll. One of the safety features in your powerhead is a design to let the belt slip if something becomes caught in the brush roll.

One result of this slip feature is belts that require occasional replacement. The length of time between replacement will vary based on your specific usage.  Should you notice a reduction in cleaning, or if the belt is not turning in the belt-view window replace the belt.

Powerhead belts are not replaced under warranty, since they are designed to slip rather than permit damage to the motor.



1.   Snap together the two interlocking wands.

2.   Push assembled wands into powerhead socket.

3.   Place cord between cord guides on handle socket, as shown and turn to position.

4.   Press cord into channels on wands.

How to Replace Worn Belt

NOTE: Disconnect power cord from electrical outlet before replacing belt. Belt pully can become hot during normal use. To prevent burns, avoid touching the belt pulley when servicing the drive belt.

When the brush roll is seated, place the new belt ZAS099-BT beside the motor pulley and roll the brush roll to wrap the belt around both pulleys.

Tilt the cover over the ridge at the front of the base and push the cover down over the base. Be sure the slot inside the cover secures the ridge. Return the two screws to the underside of the motorized nozzle and tighten with a screwdriver.
