How to Use a Powerbrush On Your Vacuum

Part # 1F13500—Wessel Werk EBK360LED Power Brush for Centaur Vacuums. Comes as a complete kit, including: Power Head with LED front lighting and 5 depth adjustments, stainless steel telescopic wand & 10ft electrified hose with “gas pump" style handle with ON/OFF switch.
Centaur Floor Machine vacuums are equipped with a power brush receptacle that is located on the motor head, labeled “For Power Nozzle Only". For a deeper clean of carpets, a power brush penetrates close to the route of the carpet fiber, extracting a greater amount of dirt over traditional, non-motorized carpet tools. This is a guide to using an optioned power brush with your vacuum.

Step 1

Insert the steel hose cuff on the powerhead hose into the intake of the vacuum and tighten the ribbed nut.

Step 2

Locate the power receptacle on the motor head.

Step 3

Insert the power cable from the power brush hose into the power receptacle.

Step 4

Turn the vacuum on, followed by turning on the power brush from the handle.

Maintenance Tips for Your Vacuum

Centaur’s machines are built with durable components that can provide 25+ years of trouble-free service as long as the machine is maintained correctly. These steps will help you protect the longevity of the machine.

The Cord

Use the blue wrap strap to carefully keep the power cable wound and stored when the vacuum is not in use.

The Tank

Wash out the vacuum tank with water after every use.

Dry Out The Vac

Remove the motor head from the tank to allow the tank and float assembly to completely dry.

The Hose

Detach the hose from the vacuum and rinse out with water. Leave it to dry.

The Latch

Do not tighten or loosen the latches. Adjusting the latches can damage the tank and will void the warranty.
