To assemble the Shark Infinity NV31W, start by attaching the handle to the main body until it clicks into place. Then, connect the hose to the back of the vacuum and secure it with the clip. Finally, attach the desired cleaning head to the nozzle.
If your vacuum loses suction, check for blockages in the hose or nozzle, clean the filters, and ensure the dust cup is empty. Also, inspect the brush roll for tangled hair or debris.
It is recommended to clean the filters every three months. Rinse them under lukewarm water and let them air dry completely before reinserting.
No, the dust cup should not be washed in the dishwasher. Hand wash it with warm soapy water and allow it to dry completely before reattaching.
Check for obstructions by removing the brush roll and cleaning any debris. Ensure that the belt is not broken or loose. Reattach the brush roll securely before use.
To change the belt, first unplug the vacuum. Remove the screws on the bottom plate to access the brush roll. Slide off the old belt and replace it with a new one, ensuring it is seated properly on the motor shaft and brush roll.
A loud noise could indicate a blockage or something caught in the brush roll. Check for debris in the hose, nozzle, and brush roll area. Also, inspect internal components for wear or damage.
For optimal battery performance, fully charge the battery before first use, avoid letting it completely drain, and store it in a cool, dry place when not in use.
The Shark Infinity NV31W comes with a crevice tool, dusting brush, and upholstery tool. Attach them to the end of the hose or wand for cleaning tight spaces, dusting surfaces, and vacuuming furniture.
Regularly clean and maintain the filters, dust cup, and brush roll. Avoid vacuuming up large debris that could cause blockages, and store the vacuum in a dry place. Follow the user manual for any specific maintenance instructions.
