Bagless System With Inverted Filter

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.

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.
