4. Setup
- Assemble the Handle: Carefully insert the handle assembly into the main unit until you hear a click, ensuring it is securely locked in place.

- Fill Clean Water Tank: Locate the clean water tank on the main unit. Open the tank cap and fill the tank with clean tap water. For enhanced cleaning, you may add a recommended floor cleaning solution. Do not exceed the maximum fill line. Close the cap securely to prevent leaks.
5. Operating Instructions
Before operating, ensure the unit is fully charged and the clean water tank is filled.

The Liectroux i5 Pro is designed for effective wet and dry vacuuming on both carpets and hard floors.
- Power On: Press the power button located on the handle to turn on the vacuum cleaner. The LED display will illuminate.
- Surface Selection: The Liectroux i5 Pro is equipped with intelligent sensors that automatically adjust suction power based on the floor type. For optimal performance, ensure the appropriate brush roller (ultra-soft for hard floors, stiff for carpets) is installed.
- Start Cleaning: Gently tilt the main unit back with your foot and begin moving it across the floor. Move the vacuum cleaner in a steady, overlapping motion for best results.
- Water Spray Function: For stubborn stains or heavily soiled areas, press the dedicated water spray button on the handle. This will release additional cleaning solution onto the floor.
- UV Sterilization: The 254nm UV sterilization lamp activates automatically during operation, providing an additional layer of hygiene by sanitizing the cleaned surfaces.
- Power Off: When finished cleaning, press the power button again to turn off the device.
6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your Liectroux i5 Pro.

The one-key self-cleaning function automatically cleans the rolling brush and pumps dirty water into the sewage tank when docked, simplifying maintenance.
- Empty and Clean Dirty Water Tank: After each use, remove the dirty water tank from the main unit. Open the lid and dispose of the collected dirty water and debris. Rinse the tank thoroughly with clean water and allow it to air dry before re-installing.
- Initiate Self-Cleaning Cycle: Place the vacuum cleaner back onto its charging dock. Press the dedicated self-cleaning button (refer to the LED display for specific instructions if needed). The unit will automatically perform a cleaning cycle for the brush roller, removing dirt, hair, and debris.
- Clean Brush Rollers: Periodically, or if you notice reduced cleaning performance, remove the brush roller from the head unit. Use the provided cleaning tool to remove any tangled hair or stubborn debris. Rinse the brush roller with water and allow it to dry completely before re-inserting.
- Filter Maintenance: The filter, located within the dirty water tank, should be cleaned regularly. Remove the filter, rinse it under running water, and ensure it is completely dry before placing it back into the tank.
- Storage: Store the Liectroux i5 Pro on its charging dock in a dry, cool place.

The integrated UV sterilization feature protects against bacteria with an effective sterilization rate of over 98%.
