1. Always clean up debris and dust from the bucket after each use. Make sure to empty the dust bag regularly, check for any holes or air leaks, and thoroughly wash it with mild detergent and warm water. Allow it to dry completely before reusing. Never use a damp or wet dust bag as it can damage the machine. 2. Inspect the power cord and plug for any signs of damage before and after use. When not in use, wind the cord neatly and secure it on the hook located on top of the machine head. 3. After completing the water suction task, check the air inlet for blockages or debris and clean it if necessary. Also, inspect the floating wave (if applicable) for any signs of damage. 4. Handle the vacuum cleaner with care. Avoid dropping it or exposing it to external impacts that could cause internal damage. 5. Store the machine in a well-ventilated and dry area when not in use to prevent moisture buildup and ensure longevity. 6. Clean the machine using a damp cloth with water or a neutral cleaning solution. Do not immerse the main unit in water. Avoid using harsh chemicals like gasoline or thinner, as they may damage the casing and reduce the machine's lifespan. 7. Avoid operating the vacuum for more than two hours continuously. Prolonged use can lead to overheating and reduce the overall performance and lifespan of the device. 8. Over time, the suction power may decrease due to clogged filters. To maintain optimal performance, wash the filter and dust bag regularly with water. Dry them completely in a shaded area before reusing to restore suction efficiency. 9. If the machine becomes excessively hot, emits a burning smell, or makes unusual noises or vibrations, stop using it immediately and have it inspected by a professional. Do not attempt to use it if it shows any signs of malfunction. 10. Avoid folding or twisting the hose frequently. Do not stretch or bend it beyond its normal limits, as this can cause damage and affect performance.
