The Vacuflo 566Q is a true cyclonic power unit that removes 100% of dust, dirt and allergens from your home while vacuuming. The cyclonic action separates debris from the airflow and forces 96%-98-% of vacuumed dirt into the canister. While the other 2%-4% of fine dust particles is exhausted outside. Vacuflo's True Cyclonic power units provide sustained cleaning power without the use of bags or filters! The powerful cleaning performance will not decrease as the dirt accumulates. The 566Q central vacuum is a work horse of the central vacuums. With a 6 Gallon dirt canister and the unit being exhausted outside the home, the 566Q requires minimal maintenance throughout the year.
