What should I check? Answer: Check for good suction at the end of the upholstery hose. If you have no suction at the end of the hose, go to step 2. Make sure the hose is firmly connected to the lower hose on back of vacuum. Is the brush turning? If not, check out our FAQ troubleshooting on “Brush is not turning”. Is the lower hose clogged? If yes, see our “Clearing Clogs” FAQ. If you don’t have any suction at the end of your hose: Check for suction at the back of vacuum after removing the hose where it attaches to the back of the vacuum (twist to the left to remove hose). If there’s suction at the back, check the hose for cracks or holes. If there is no suction at the back of the vacuum, see step d). If there are none, the hose is probably clogged. Please see our “Clearing Clogs” FAQ. If there’s no suction in the back, check the area below for suction (without removing the small round filter). This is the locking lever for the dirt container. If there is suction, make sure all filters are clean and hose is clear as the unit itself does have suction. Check the dirt cup to see if it is empty. Make sure the dirt container and upper tank are positioned and installed correctly and the dirt cup is locked into place. Check the inner and outer circular filters (located under the dirt cup), the post-motor filter (behind the vented door in front of the vacuum), and the pre-motor filter (underneath the filter cup in the round center portion of the Lock ‘n Seal Lever) for debris. Reduced air-flow from dirty filters or clogs will put greater stress on the motor, increasing the possibility for overheating. check the upper-tank louvers (the slits in the plastic insert in the upper tank), as they may need to be rinsed. The filters may be hand washed in cold water with mild detergent. Only reinstall filters when they’re completely dry. Note: the white post-motor filter is not washable. You may want to try a higher floor setting. You can adjust the height using the dial in the center of the vacuum’s base. If you still can’t get any suction, at this point it might be best to take your vacuum to a technician.
