Abstract
A light-weight, quiet vacuum cleaner assembly for a backpack vacuum cleaner includes an air inlet for communicating with a vacuum cleaner hose and a filter; a vacuum motor for drawing air through the vacuum cleaner hose, air inlet, and filter; a quiet exhaust assembly module in communication with the vacuum motor for expelling and quieting exhaust from the vacuum motor, and wherein the vacuum cleaner assembly weighs 2-12 lbs. and includes a flow rate (CFM) to noise (dbA) ratio (flow rate/noise) of at least 0.6.

A light-weight, quiet vacuum cleaner assembly for a backpack vacuum cleaner including a backpack assembly for carrying the vacuum cleaner assembly on a user's back, a vacuum cleaner hose for vacuuming debris from a surface, and a filter for filtering out vacuumed debris, comprising:
- an air inlet for communicating with the vacuum cleaner hose and the filter;
- a vacuum motor for drawing air through the vacuum cleaner hose, air inlet, and filter;
- a quiet exhaust assembly module in communication with the vacuum motor for expelling and quieting exhaust from the vacuum motor,
- wherein the vacuum cleaner assembly weighs 2-12 lbs. and includes a flow rate (CFM) to noise (dbA) ratio (flow rate/noise) of at least 0.6.
A light-weight, quiet vacuum cleaner assembly for a backpack vacuum cleaner including a backpack assembly for carrying the vacuum cleaner assembly on a user's back, a vacuum cleaner hose for vacuuming debris from a surface, and a filter for filtering out vacuumed debris, comprising:
- an air inlet for communicating with the vacuum cleaner hose and the filter, the air inlet including an intake area;
- a vacuum motor for drawing air through the vacuum cleaner hose, air inlet, and filter;
- a quiet exhaust assembly module in communication with the vacuum motor for expelling and quieting exhaust from the vacuum motor,
- wherein the quiet exhaust assembly module includes a stage of exhaust openings having a total area and the ratio of the total area of the stage of exhaust openings to the intake area of the air inlet is at least 3:1.
