1. Check to make sure the front cover is shut completely. You should hear it click into place.
2. Next, check to see if the bag is more than ½ full. If it is, install a new bag. If it’s not, go to step 3.
3. Check for good, strong suction at the end of the upholstery hose. If you don’t get good suction, go on to step 4. If there’s good suction at the end of the hose, check to see if the hose is firmly connected to the lower hose. Check the upper and lower hoses for clogs (see our “Clearing Clogs” FAQ for details) Also, check if the brush is turning. Remove the access plate(a plastic frame over the brush roll) and check the brush and belt for damage. Be sure to clean off any debris on the brush. If brush won’t turn by hand, you’ll need to replace the brush. You can do so by clicking here: http://www.bissell.com/parts/?sc=part&productid=2453&partid=17048

4. Check for suction at the back of the vacuum after twisting the hose to the left and removing it from the hose cuff (where the hose attaches to the back). Make sure the bag and door are installed properly. If you don’t get good suction, go on to step 5. If you do, check the hose for cracks or holes. If there are no cracks or holes, the upholstery hose is probably clogged.
5. Check the pre and post motor filters for debris. Dirty filters can restrict airflow. The filters may be hand washed in cold water with mild detergent. Only reinstall filters when they are completely dry.
6. If you still have no suction, please take your vacuum to a technician. You can find your nearest BISSELL® Authorized Service Center by clicking http://www.bissell.com/support/product-support/service-centers/ or by calling 1-800-237-7691, available 24 hours a day.
