To assemble your Shark Navigator NV250, start by attaching the handle to the top of the vacuum body until it clicks into place. Then, connect the hose to the back of the vacuum. Finally, attach the cleaning wand and any desired accessories.
If your Shark Navigator NV250 loses suction, check for blockages in the hose, dust cup, or filters. Clean or replace filters if necessary. Ensure that the dust cup is not full and that all connections are secure.
The pre-motor foam and felt filters should be cleaned every three months. The HEPA filter should be cleaned once a year. Make sure all filters are completely dry before reinserting them into the vacuum.
To empty the dust cup, first detach it from the vacuum by pressing the release button. Hold the dust cup over a trash can and press the bottom door release button to empty its contents. Close the bottom door and reattach the dust cup to the vacuum.
If the brush roll is not spinning, check to ensure that the vacuum is in the proper mode for carpet cleaning. Clear any debris that may be wrapped around the brush roll and ensure the brush roll is properly engaged.
Yes, the Shark Navigator NV250 can be used on hardwood floors. Make sure to turn off the brush roll to avoid scratching the floor. Use the appropriate floor settings for optimal performance.
Regular maintenance includes emptying the dust cup, cleaning the filters, and checking for blockages. Periodically inspect the brush roll for tangled hair or debris and clean it as needed.
If the vacuum overheats, it may shut off to protect the motor. Turn off the vacuum and unplug it. Check for blockages and clean the filters. Allow the vacuum to cool for at least 45 minutes before using it again.
To replace the belt, first ensure the vacuum is unplugged. Remove the bottom cover of the vacuum head to access the brush roll. Remove the brush roll and replace the old belt with a new one, following the grooves on the brush roll and motor shaft. Reassemble the vacuum head.
Store the Shark Navigator NV250 in an upright position in a cool, dry place. Ensure that the power cord is neatly wrapped. Keep the vacuum away from direct sunlight and moisture to maintain its longevity.
