- Garden Watering: The 'Shower' mode is ideal for gently watering plants.
- Floor/Patio Cleaning: Use a direct jet (0°) or narrow fan (15°) for stubborn dirt, and wider sprays for general cleaning.
- Furniture Cleaning: Adjust the spray to a suitable fan pattern to clean outdoor furniture without damage.
Maintenance
- Clean the Filter Screen: Regularly check and clean the filter screen at the end of the water hose to prevent blockages and prolong the service life of the pump. Remove any debris like sand, gravel, or withered leaves.

- Always store the battery in a cool, dry place.
- Do not expose the battery to extreme temperatures.
- If storing for extended periods, charge the battery to about 50% and recharge every few months.
