To clear the main upholstery 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.
To clear the lower hose:
Start by removing the upholstery wand from the lower hose. Remove the 2 screws that secure the lower hose tube (pictured below), and pull outward to release lower hose. Once released, lay the lower hose along the floor and push the broom handle through to the brush area to remove the clog.
