What do I check? Answer: Check the dirty cup to see if it is empty. Check the Pre-Motor and Post Motor filters. The Pre-Motor filter (either all grey and black or grey and white) should be checked at least once a month (or more depending on use) and cleaned or replaced as needed. The Pre-Motor filter can be accessed by removing the Easy Empty dirt tank from the vacuum base. The filter will be located directly under where the dirt tank sits. Grasp the filter and remove it from the vacuum. While holding over the trash, gently separate the layers of the filter (being careful not to rip the layers) and shake out the excess debris. The filter may also be rinsed with warm water. Allow the filter to completely air dry before replacing. If it is damaged, replace with new filter. The Pre-motor filter can only go in one way. the thinnest part of the foam filter will face down when putting back in place on the machine. In addition, the filter has a special shape to it that makes it only go in one way. The Post-Motor filter assists in the filtration process to return clean air to the room. This filter should be replaced every three to six months depending on use of the vacuum. The Post-Motor filter is located in front of the vacuum near the height adjustment knob. It is easiest to have the vacuum fully reclined to access the filter. Remove the filter door by pressing latch downward. Remove the filter by grasping the handle on the front of the filter and pulling it out of the vacuum. **NOTE: the white pleated filter can be washed with water and a mild detergent. Please allow it to completely dry before putting back into machine. Replace with the handle of the filter facing you. Replace the door by hooking the bottom into the grooves and rotate toward the machine snapping into place. If the filter is damaged or too dirty, replace with a new filter. More frequent filter cleaning or replacing may be necessary if you are vacuuming new carpet, fine dust, powders, or have allergy concerns. Make sure the hose is connected firmy to the foot of the machine. The hose goes into the slot to the left of the height adjustment knob (if you are facing the front of the machine). If it is not firmly connected, the machine will lose suction power. Check for GOOD suction at the end of the upholstery hose. If there is good suction at the end of the hose, make sure again that the hose if firmly connected to the foot of the mchine. The hose goes into the slot to the left of the height adjustment knob (if you are facing the front of the machine). If it is not firmly connected, the machine will lose suction power. Is the brush turning? If not, unplug the machine, recline so the machine is flat on the floor, turn it over, unscrew the seven (7) screws with a Phillips head screwdrive (magnetic is necessary) (See Picture below). Turn the machine back over, with the machine still reclined, and lift the plate straight up and set aside (see picture below). Grasp the brush at both and lift to remove. Clean off any debris, hair, or string. If the brush appears worn or the ends seem jammed, the brush will need to be replaced. If you have no suction at the end of the hose...proceed below: Check for suction at the suction inlet for a clog. With the dirt tank locked in place ON the machine, remove the hose (follow arrows where the hose enters to lock and unlock) and check for suction at the suction inlet where the hose enters the back of the vacuum. If you have suction here, there is a clog in the hose. Take a broomstick and push it through the entire length of the hose to remove any debris. Then take the hose out of the foot and push a broomstick through the entire length of the foot hose to clear any obstructions. Once cleared, put the hose back on and check for suction again at the end of the hose. If there is still no suction, the clog is still in there, work to clean it out. As long as you have suction at that inlet on the body of the vacuum, there is nothing wrong with the vacuum, it is a clog. If you have no suction at the inlet on the vacuum, you will need to take your machine to one of our BISSELL Authorized Service Centers for inspection.
