This Trillium unit produces 700 Air Watts of power! The water-lift measure is 142 inches of tremendous suction. This unit is quiet at 64 dcb. The unit is hybrid, meaning that you have the option of attaching bags or keep it bagless. It comes with a filter pouch that must remain inside the unit. Keep in mind that if you decide to insert bags to accept the garbage, this will reduce the suction of your unit. But it is a cleaner way of disposing garbage that is collected.
