5. Maintenance
Emptying the Dustbin
- Ensure the vacuum cleaner is powered off.
- Press the dustbin release button (usually a small lock icon) to open the dustbin cover.
- Carefully empty the collected debris into a trash receptacle.
Cleaning the Filter
- After emptying the dustbin, twist and remove the filter assembly from the dustbin.
- Separate the metal filter and the HEPA filter element.
- Rinse both filters under running water until clean. Do not clean the main body of the vacuum.
- Allow the filters to air dry completely before reassembling. Ensure they are thoroughly dry to maintain optimal suction and prevent damage.
- Reinsert the HEPA filter into the metal filter, then place the assembly back into the dustbin.
- Close the dustbin cover securely until it clicks into place.

6. Troubleshooting
- Low Suction: Check if the dustbin is full and empty it. Ensure the filters are clean and properly installed. Verify that no attachments are clogged.
- Device Not Turning On: Ensure the battery is sufficiently charged. Connect the device to the charger and allow it to charge for at least 30 minutes before attempting to power it on again.
- Short Battery Life: Ensure the device is fully charged before use. Avoid using Max Mode continuously for extended periods if longer runtime is needed.
- Unusual Noise: Check for any obstructions in the suction inlet or attachments. Ensure all parts are securely assembled.
