To assemble the Shark Vertex MultiFLEX IZ440H, first attach the wand to the floor nozzle. Then, connect the handheld vacuum to the top of the wand. Ensure all connections click into place.
Remove the dust cup and take out the pre-motor foam and felt filters. Rinse them under lukewarm water until the water runs clear. Allow them to air dry completely for at least 24 hours before reinserting.
Check for blockages in the hoses, wand, and floor nozzle. Ensure the dust cup is empty and filters are clean. Additionally, inspect the brush roll for any tangled debris.
Regularly check the brush roll for tangled hair and debris. Use scissors to carefully cut away any entangled matter. Ensure the brush roll spins freely after cleaning.
Detach the handheld vacuum from the wand or floor nozzle. Attach any desired accessories directly to the handheld unit to clean furniture, stairs, or other surfaces.
Ensure the vacuum is fully charged. Check the battery indicator to confirm. If it still doesn't turn on, try resetting the unit by disconnecting and reconnecting the battery.
Press the MultiFLEX lock button to fold the vacuum over. This allows the unit to be stored in a compact, upright position, ideal for saving space.
Yes, the vacuum is suitable for use on hardwood floors. Use the hard floor setting to ensure gentle cleaning without scratching the surface.
The HEPA filter should be replaced every 12 months for optimal performance, or sooner if you notice a decrease in suction or if the filter appears damaged.
The vacuum comes with a crevice tool, dusting brush, and pet multi-tool, allowing for versatile cleaning of various surfaces and hard-to-reach areas.
