Check & clean your vacuum regularly to maintain full pickup power
Remember when your vacuum could pick up tall buildings, was more powerful than a locomotive, faster than a speeding bullet? If it seems to be running fine, but just doesn’t suck up dirt like it used to. Unplug it and check the components. A dust bag that’s full will reduce suction. Change or empty it when it nears the “full” line. Some models also have filters to keep dust out of the motor. They need regular cleaning or replacement to maintain full pickup power.
Also the hose or wand might be blocked with debris. Attach the hose to the exhaust and hold the other end to the intake. If no debris is dislodged, use a broom handle or garden hose to remove the blockage. Push gently to avoid tearing the hose. Finally, check all rubber drive belts and replace if needed. Supplies for most popular machines are sold almost everywhere and online.
