Shark Rotator Professional Lift-Away Vacuum, NV502 - lift-away vacuum - Page 3 Questions & Answers
Have lost suction on my shark rocket HV321 what do I check
1. A common place where loss of suction can happen is on the floor nozzle hose. At the base of the vacuum cleaner is a short hose about 6".
The hose will tear where it bends back and forth. You can find a replacement hose but to install it is difficult.
2. On the neck of the handle is a suction release window (valve). It is used to reduce suction power to vacuum curtains or clothes etc. The valve will often turn on accident and stay open reducing suction power. When the valve is opened, pushing and pulling the sweeper is easier.
3. The filters maybe dirty and clogged. Check ALL the filters. Some Sharks have 3 filters including HEPA. Shark HEPA filter are made of fiberglass therefore can be washed with the others.
4. Check for clogs anywhere dirt can travel until it reaches the dirt cup.
Why will Power switch will not stay on?
The power switch cold be broken and not working.Check to see if the filter is clogged and check for a clogged hose or filter and unclog the hose and replace the filter.
