Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your vacuum cleaner.
1. Emptying the Dustbin

2. Cleaning the Filters
The vacuum features an efficient filtration system. Regular cleaning of filters is crucial for maintaining suction power.
- Twist and pull out the filter assembly from the dustbin.
- Separate the metal filter and the HEPA filter.
- Tap off loose dust from both filters over a trash can.
- Rinse the filters under cold running water until the water runs clear. Do not use detergent.
- Allow filters to air dry completely for at least 24 hours before reassembling and placing back into the vacuum. Do not use a dryer or direct heat.
- It is recommended to clean filters monthly, or more frequently with heavy use. Replace filters every 3-6 months depending on usage.

4. Battery Care
