TURBINE POWERHEAD FOR P/N 7160, 7161 and 7210

These Turbine Powerheads have been carefully designed and manufactured for long life, reliable performance and convenient cleaning. They are designed to do most of the cleaning work for you. They move easily and do not require downward pressure for thorough cleaning. As with any tool with moving parts, caution must be exercised while using these Turbine Powerheads. Please read and save these Operating Instructions.


1. Keep hair, hands, and feet away from rotating brush while the Turbine Powerhead is running.  3. Do not attempt to service or unclog Turbine Powerhead while unit is running. 
2. Remember that Turbine Powerhead operates whenever they are connected to a running vacuum. If children are present, make sure to turn vacuum system off when leaving Powerhead unit unattended.  4. Avoid picking up water or spilled liquid with your Turbine Powerhead. The vacuum system is designed for dry pick up only. 

Instruction for this Turbine Powerhead


To attach your metal wands, simply twist into Powerhead neck elbow until it fits snugly. The built-in, locking mechanism will prevent the wand from coming loose from your Powerhead while in use. To detach wand, depress wand release tab on the back of neck with foot or hand and twist wand free.

IMPORTANT:  Do not insert button-lock lower wand with the Turbine Powerhead neck. It will get jammed and you will not be able to take it apart.

The wand can be locked in an upright position by pushing it forward until the lock is engaged. This lock position is convenient for storage and lifting the Powerhead. To release wand from the vertical locked position, gently place foot on Powerhead, grasp wand and pull back firmly.

Allegro Central Vacuum TurboCat Manual



Your Turbine Powerhead has no ON/OFF switch. Whenever it is attached to an operating vacuum system, it will be running.  No adjustments to the powerhead are necessary for different types of carpeting.

To ensure maximum efficiency of the Turbine Powerhead, make sure that any filters, bags and cleaning hoses in your vacuum system are clean and free of blockage.



Threads, string, carpet fiber, fuzz and hair occasionally become wound around the brush assembly.   These should be routinely removed to keep the brush assembly clean and to maintain efficiency.

1. Disconnect the Powerhead from the hose and wands. Be sure parts have stopped spinning before working on the turbine powerhead. 
2. Turn the powerhead over. 
3. Strings and other entangled items can be removed by unwinding them by hand or carefully cutting with scissors.

2. Turn the powerhead over and remove the clear belt cover, by first rotating the two latches counterclockwise until they align with the openings in the belt cover. Lift the belt cover out from under the base plate. 
3. Remove debris from the intake and turbine. Rotate the brush roller to ensure system is clear. Make sure the orange seal on belt cover and mating surfaces are free from dirt particles before reassembling.  Check belt condition and position on sprocket and on brush roller.
