1. First, check to see if dirt-cup is full. If it is, empty it. Also, clean the screen in the upper tank, pictured below.
2. Check for clogs in the upper hose. First, detach the hose from the vacuum. Push a broomstick into the hose to push any obstruction to the end of the hose where it can be removed.
Note: A coat hanger is not recommended to clear a clog as it may damage the hose.
3. Check for clogs in the lower hose. Recline the vacuum and roll it over so the backside faces up. Remove the single screw at the hose wand base and straighten the lower hose (next to the right wheel). Look through the hose for obstructions. Push a broomstick through lower hose to unclog. The blockage should come out in the brush roll area. Note: A coat hanger is not recommended to clear a clog as it may damage the hose.
