1. First, check the dirt cup to see if it is empty.
2. Next, check the dirt-cup release handle to make sure it’s completely locked into place (see below). If not locked into place, the dirt-cup may not seal to the upper tank properly and suction may be affected.
3. Check the back of the dirt cup to make sure it’s completely locked into the tabs. If dirt-cup isn’t locked into tabs, the dirt cup may not seal to the upper tank, again possibly affecting the suction. (See pictures below).
4. Take a look at the top of dirt cup to make sure it’s completely sealed to the upper tank. Use the pictures below as a guide.
5. Unplug your vacuum and then check the filters. Dirty filters can restrict air flow. The Inner and Outer circular filters are found under the dirt-cup The Pre-Motor filter is a small round filter found under the filter tray. The Primary Separator is the large piece of plastic in the upper tank. All of these filters can be washed with warm water and mild detergent. Reinstall the filters only when they are completely dry.
6. Check for good, strong suction at the end of the upholstery hose. If you don’t get good suction, go on to step 8. 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). If this doesn’t work, go on to step 7.
7. 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:

8. Next, 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). If you don’t get good suction, go on to step 9. If you do get good suction here, check the hose for cracks or holes. If there are no cracks or holes, the upholstery hose is probably clogged. Push a broomstick into the hose to push any obstruction through the end of the hose. (See our “clearing clogs” FAQ for details.)
9. If you still don’t have any suction, please take your vacuum to a technician. You can find your nearest BISSELL® Authorized Service Center by clicking http://www.bissell.com/service-centers/ or by calling 1-800-263-2535, available 24 hours a day.
