2. Attaching the Battery
Slide a charged battery into the base of the vacuum cleaner handle until it clicks securely into place. Ensure it is firmly seated to prevent accidental detachment during operation.
3. Assembling the Dust Cup and Nozzle
Attach the transparent dust cup to the main unit. It is crucial to not only push the dust cup in but also to twist it clockwise until you hear a "CLICK!". This ensures the internal latches engage and the dust cup is fully locked, preventing it from detaching during use.

Maintenance
1. Emptying the Dust Cup

2. Cleaning the Filters
Regular filter cleaning is essential for maintaining suction power and extending the life of your vacuum. The vacuum features a high-density washable HEPA filter and a steel pre-filter.
- Step 1: Turn off the vacuum cleaner for safety.
- Step 2: Hold the dust cup firmly and rotate it counter-clockwise to unlock it, then pull it out from the main unit.
- Step 3: Hook your fingers under the base and gently lift it to remove the HEPA filter assembly.
- Step 4: Rotate the HEPA filter base counter-clockwise to separate the inner filter from the outer housing.
- Step 5: Use the provided filter cleaning brush to remove loose debris from both filters.
- Step 6: Rinse both the HEPA filter and the steel pre-filter under running water until clean.
- Step 7: Allow all filter components to air dry completely before reassembling. Do not reassemble or use the filters while damp, as this may reduce efficiency or cause mold.
Tips: Clean filters every 1-3 months (or more frequently for heavy use). Replace the HEPA filter annually or if damaged.
