Why Is My Vacuum Losing Suction?

Overfilled Bag

• Vacuum cleaner bags and collection containers should be replaced when they are half full. When vacuum receptacles are left to operate more than half full of dirt and debris, airflow is restricted through the vacuum, causing a loss of suction power. Overfilled bags will also cause dust particles to be released back into the air flows through the appliance, making cleaning far less effective.

Clogged Filter

• Vacuum cleaners are equipped with filters that filter any air that has been released from the bag before it re-enters a room. However, in order for filters to properly do their job, they must be cleaned or replaced on a regular basis. Clogged filters will restrict air flow throughout the appliance, making suction less efficient. Depending on the frequency with which you vacuum, filters should be cleaned every two to four months.

Clogs

• Although most people are aware that you shouldn't vacuum up large objects, such as lint balls or socks, the occasional accident can happen. When a large object is suctioned through the vacuum brushes or a hose attachment, it can prevent air from flowing through the proper channels and greatly reduce suction power. When you suspect a clog, use a flashlight to inspect the entry portals of the vacuum while it is unplugged from a power supply. Remove the clog with your hands, or a wire coat hanger, or take the machine to a professional for stubborn items that you are unable to remove at home.

Worn Brushes

• The underside of vacuum cleaners are equipped with brush rolls that spin and assist suction. Over time, vacuum brushes can become worn or entangled with pieces of string or other household debris. Brushes that are not spinning efficiently will cause excess strain on the vacuum motor and, thus, reduce suction power. Worn brushes should be replaced, while brushes in good condition should be cleared of debris before each cleaning.
