Cyclo Vac Central Vacuum Bag and Bagless Systems

Models with bag – High Efficiency Collection

Central vacuums from Cyclo Vac’s High Efficiency Collection are equipped with disposable bags. This type of central vacuum is chosen mainly because of its ease of maintenance and because there’s no contact with dust when the vacuum is emptied. Indeed, a convenient disposable electrostatic filter bag captures dust and assures maximal and constant suction power, even if the bag is full. People who suffer from allergies or who have pets will appreciate the fact that they are not in contact with vacuumed dust, dander, feathers or fur. Simply remove the bag, seal it, discard and reinstall a new one. Bags are inexpensive and their replacement depends on frequency of use.

At the forefront of research and innovation, Cyclo Vac’s prestigious High Efficiency Collection establishes a whole new standard in the cleaner vacuum industry. This innovative collection introduces an entirely new multiple filtration system. It includes:

  • A convenient disposable electrostatic filter bag. No matter the volume of dust inside, it ensures constant maximum vacuum power;
  • Filtration is further ensured by a Cyclofiltre™ treated with Ultra-Fresh to prevent the growth of mold, fungus and bacteria;
  • Our patented carbon dust filter, available with most of our ducted vacuums, captures the fine black dust produced by the motor.

Models without bag – Tradition Collection

Central vacuum models with filters from our Tradition Collection have many interesting advantages. This type of central vacuum is chosen mainly because it’s considered environmentally friendly. The centrifugal force simply directs the dust particles to the bottom of the dust canister. Indeed, there’s no bag to throw out and filters are washable. Furthermore, there are no bags to buy, so in the long term, maintenance is not only ecological, but also less costly.

Our Tradition Collection established the standards for performance and filtration in the ducted vacuum system industry. Here’s how its multiple filtration system works:

  • The first dust barrier consists in the simple cyclonic circulation of air. The centrifugal force directs the dust particles to the bottom of the dust canister;
  • The machine washable pre-filter then catches any remaining fine dust particles;
  • Finally, our exclusive Cyclofiltre™, treated with Ultra-Fresh to prevent the growth of mold, fungus and bacteria, captures the micro particles. Conveniently, it is also machine washable;
  • For enhanced filtration, our patented carbon dust filtration, available with most of our ducted vacuums, captures the fine black dust produced by the motors.

True Cyclonic System
Other filtrations systems and their disadvantages!
Are you considering the purchase of a central vacuum cleaner with the following filtration systems? "Self cleaning filter" or Central vacuum system with "True Cyclonic" filtration system.

There are many claims to ultra-efficiency and cleanliness, but be careful not to fall victim to clever marketing methods ranging from "true cyclonic", "100% efficiency at all times", "guaranteed never to clog", and filters with "Self cleaning filters", "no filters to be replaced or washed - EVER".

True-Cyclonic® Action with Outside Exhaust

In a cyclonic unit, the dirty air is forced through the vacuum chamber in a tornado style of movement. The heavier dirt falls down the bottom of the canister and the lighter dust is carried off through the motor and then exhausted outside.

Manufactures Claim:
True Cyclonic Power Units provide sustained cleaning power by separating the dirt from the airflow without the use of bags or filters! The powerful cleaning performance of the True Cyclonic will not decrease as dirt accumulates. There are no replacement filters or bags to buy.


  1. Air Quality: The lighter dust that contains household dirt, hair, sand, dead skin flakes, dust mites, feces, pollen, bacteria, carpet fibers, smells and many more lung damaging particles such as dander, rotting food particles, pet mildew are vented outside the house, which may recycle back in your house.

  2. While cyclonic action does remove the heavy particles, the light fibers and dust are emitted through the fan blades creating havoc with the motor and decreasing its life. Over-heating and eventually motor failure will occur when dirt and debris is broken up by the fan blades knocking the motor out of balance.

    Suppliers will try to get you to believe that vacuum motors in a cyclonic unit will last as long as others, or that the dirt that passes through a cyclonic motor will not effect anything. This information is simply not true.

  3. More myths about the true-cyclonic central vacuum units are that they "never lose suction" or "have no filters". This information information is again not true.

    A guard screen is located directly above the dirt pan inside the power unit. It should be inspected and cleaned occasionally. This is to prevent such things as carpet fiber, cloth, etc. from getting into the motor's impeller blades. A buildup of dirt or other larger, clogging-type material may result in loss of vacuum.

  4. Overfilling could cause debris to be drawn into the impeller blades which may severely damage your power unit.

"Self Cleaning Filter" systems with "Inverted Bags"

How This Filtration "Suppose" to Work
When the unit is on, air flows in through the inlet port causing the permanent filter bag to rise. Cyclonic air circulation in the power unit suspends dust and dirt inside the filter bag. When the unit is turned off, gravity and the weighted sleeve lower the filter. When the permanent filter drops completely down, collected particles are suppose to fall into the receptacle for emptying as needed. But unfortunately this work only in theory

Manufactures Claim:
Permanent Self-Cleaning Filter. No filters to be replaced or washed - EVER.


  1. This type of system requires more maintenance because the suction will dramatically decrease once the canister starts to get full.
  2. A unit that becomes a real mess to clean out.
