Shark Navigator Lightweight Upright Troubleshooting

This troubleshooting page will assist with diagnosing problems and applying solutions for the Shark Navigator Lightweight Upright vacuum.

After many attempts of trying to vacuum up the same piece of debris, the suction is still too weak.

If the vacuum’s power is on, but fails to pick up dirt, the issue may be a stalled revolving brush head. The brush head could be broken or otherwise incapable of operating. For brush head replacement, click here

If vacuum components are clear and appear to be working properly, the vacuum motor may be failing. This is the central motor in the heart of the vacuum that provides the suction.

Smell coming from vacuum is foul and getting stronger.

If the dust cup is full, empty and clean it. If the smell remains, remove filter cup and wash foam pads. Additionally, the dust cup may need to be replaced, for proper replacement,click here.

If there is a burning smell, the motor may be failing. Consider a motor replacement. For replacement guide, click here.

Vacuum is switched on, but nothing is happening.

Make sure vacuum is completely plugged into outlet. Check if outlet is working. If not, try a separate outlet. If unsuccessful, could be a wiring issue.

There may be blockages in the hose. The vacuum is equipped with a safety feature that prevents the vacuum from powering on in response to blockage. Check to see if hose is clear. To detach hose, click here.

Vacuum will hardly move.

If vacuum is difficult to push, something may be caught in the wheel. Inspect wheel and clean out debris. If this does not resolve the issue, consider replacing the wheel.

There may be potential blockages formed from rugs or other forms of lengthy material. This material can wind around and prohibit the brush head from rotating, limiting the ability to move the vacuum. For Brush Head inspection, click here.

Once the vacuum is turned on, it is making a funny noise.

If vacuum is making sounds, debris may be caught in the hose. To remove debris, take off the hose and clear the hose. To detach hose, click here.

The bin may also be full. Thoroughly clean the bin out and continue use. If any problems arise refer to solutions above for troubleshooting.
