Bagless System With Inverted Filter
Another Type Of Filtration On The Market


You have to directly deal with dirt in a bagless system.

Magnified E.ColiMagnified bacteriaDo You Know What's
In Your Canister?
Many things can be collected in your dirt canister such as household dirt, hair, sand, dead skin flakes, dust mite feces, pollen, bacteria, carpet fibers, smells and many more lung damaging particles such as dander, rotting food particles & pet mildew. You may also have such things as dead bugs, spiders, dead ants, dead lizards, dead flies etc... You get the idea.

This is a form of cyclonic or dirt circulation which enters the unit and whirls around like a tornado where the heavier dirt falls to the bottom into the bucket, and the lighter dust gets filtered out by a cloth type filter or foam filter. This filter separates the dirt from the air stream and prevents the dirt and dust from entering the fan, armature and bearings of the motor and possibly back into your living area. Two or three layer filtration traps and removes even the smallest dust and dirt particles from the air stream, but cannot prevent such things as mold, bacteria etc. from growing.

Bagless is a dirty word!
Did you know that the cleaning performance diminishes quickly as the permanent cloth filter become clogged with dirt. 100% of the airflow is forced through the permanent cloth filter, no cyclonic air flow or path can be achieved, resulting in dirtier filters thus greatly reducing the vacuums' suction power and increasing the clogging potential.


When the unit is shut off that's when the debris falls into the container, but doesn't clean off the little dirt particles and film that remains on the filter. Reducing the original performance each time you use the vacuum. The cloth filter can not be restored back to its original state once dust and dirt start to get embedded into the filter. There are different coatings that can help reduce the amount of embedded filth like GOR-TEX and Teflon but do not eliminate it completely.

How This Filtration Works

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 fall into the receptacle for emptying as needed.

One advantage of this filtration type is the benefit of not having to purchase replacement bags. You are also required to vent this type of system outside. This type of system requires more maintenance because the suction will dramatically decrease once the canister starts to get full. If not cleaned and maintained on a regular basis, the filter may become clogged causing permanent motor damage.

Be careful and be aware of "Self-Cleaning" filters. Sorry, but we have found many problems with some companies that make this claim. The biggest problem we have found is that the average customers will believe that statement... until they own this type of unit! Afterwards they become stuck with a unit that becomes a real mess to clean out. Some companies will call this a permanent drop-down inverted filter, which is said to be "breathable". We call that a "mess".

Why would anybody want a
bagless system?

Typical, so-called self-cleaning "bagless" system.
The permanent motor filter you see dropping down is not a paper bag.

"A picture says a thousand words."

This is what you'll have to contend with
when you buy a bagless central vacuum.

 It's highly recommended to protect yourself from direct contact with dirt and dust
Buying a bagless vacuum is not really a good idea.

Case in point, this is why people don't like dealing with bagless vacuums. Why would you?
