- Check for clogs in the lower hose.
- Safety first! Make sure your machine is unplugged before you remove the screw from the left side of the lower hose on the back of the unit. Lay the vacuum on its side, with the lower hose facing up.
- With the hose loose, straighten it into one line. Look through it for any blockages. Push a broomstick through the lower hose to unclog it.
- Vacuum the area thoroughly where dust is blowing up as the brush will continue to rotate. The rotating brush causes debris to move up through the hose.
- Make sure the Dirt Tank is empty.
- Your vacuum has three filters. Check the Inner and Outer Circular Filters in the Filter Cup and the Post-Motor Filter on the front of the machine for debris. Also check the Upper Tank Louvers (this is a grey plastic piece that looks like a filter). Dirty filters restrict air flow. They may be removed and washed in cold water with mild detergent. Let them dry completely before reinstalling. The white Multi-Layer Post Motor Filter is not washable.
- Check for good suction at the end of the Upholstery Hose with a Handle. If there is good suction, make sure this end of the hose is firmly pressed into the lower hose outlet on the back of the vacuum. Also make sure the brush is rotating. If it isn’t, remove the plate at the bottom of the vacuum by the two tabs, check the belt, and clean the roller. If the lower hose is clogged, remove the hose with handle and clean this hose.
- If there isn’t good suction, remove the hose by twisting it off the back of the machine and check for suction on the vacuum. If suction power is good, check the hose for cracks or splits and use a broomstick to push any dirt or debris through the hose.
