1. After each use, make sure to remove any debris and dust from the bucket. Clean the dust bag thoroughly with warm water and a mild detergent, then let it dry completely before reusing. Never use a damp or unclean dust bag as it can affect performance and cause damage over time. 2. Always inspect the power cord and plug for any signs of wear or damage. After using the machine, wind the cord neatly and secure it on the hook located on the top cover of the unit to prevent tangling or damage. 3. After completing water absorption tasks, check the air inlet for blockages or dirt. If necessary, clean it carefully. Also, inspect the floating wave (if applicable) to ensure it is not damaged or worn out. 4. Handle the vacuum cleaner with care. Avoid dropping it or subjecting it to strong impacts, as this can damage internal components and reduce its lifespan. 5. When not in use, store the vacuum in a well-ventilated and dry area. This helps prevent moisture buildup and ensures the unit remains in good working condition. 6. For cleaning, use a slightly damp cloth with water or a neutral detergent. Do not immerse the main unit in water. Avoid using harsh chemicals like gasoline or thinner, as they can damage the casing and lead to cracks or other issues. 7. To maintain the longevity of the vacuum, avoid running it continuously for more than two hours at a time. Prolonged use can overheat the motor and reduce overall performance. 8. Over time, the suction power may decrease due to clogged filters or dust bags. To keep suction strong, regularly wash the filter and dust bag with water. Let them dry completely in a shaded area before reinstalling them. 9. If the vacuum starts to overheat, emits a burning smell, or makes unusual noises or vibrations, stop using it immediately and have it inspected by a professional. Continuing to use it in such conditions can cause further damage or even safety hazards. 10. Avoid bending or folding the hose excessively. Do not stretch it beyond its limit or twist it too much, as this can cause kinks or damage that reduces efficiency and may lead to leaks or breakage.
