Prior to checking for clogs in your vacuum, turn the machine off and unplug the cord from the electrical outlet. Proceed to check the following:
DIRT CUP AREA - Empty the dirt cup. Remove the lower portion of the cup and clean the screen and check the center tubes for dirt accumulation. - Check the dirt inlet. This is the opening located behind the canister and is only visible once the canister is taken off the machine.
UPPER HOSE - Detach the hose from the machine by twisting the hose collar counterclockwise. Push a broomstick into the hose to push any obstruction to the end of the hose where it can be removed. - Check the clear diverter area at the back of the machine. When the hose wand is removed from the base, the diverter should be in the up position. If a clog is visible near the diverter, remove the divertor cover by removing 7 screws and clear the obstruction. NOTE: Be careful not to dislodge the gasket.
LOWER HOSE - Recline the machine back and roll it over so the backside is facing up. Remove the bottom 4 screws from the diverter cover to loosen, and straighten the foot hose. Look through the hose for obstructions. Push a broomstick through the lower hose to unclog this. (Any obstruction should exit through the suction path at the brush roller).
FILTERS - Check the pre-motor and Multi-Layer Post Motor Filter for debris. Dirty filters can restrict airflow. The pre-motor filter is located underneath the canister of the vacuum in the pull out tray labeled "filter". This may be hand washed in cold water with mild detergent. Reinstall this filter when it is completely dry. The Multi-Layer Post Motor Filter cartridge needs to be replaced and cannot be washed. This is located on the side of the machine inside the filter grill.
