1. When using the vacuum cleaner, make sure to empty the dust from the filter bag or filter regularly to maintain optimal performance and prevent clogging. 2. It's important to lubricate the vacuum cleaner’s shaft periodically and replace the brush with one of the same quality or grade to ensure smooth operation and extend the life of the device. 3. Always inspect the air duct, nozzle, hose, and air inlet for any blockages or foreign objects. Using the correct nozzle for different cleaning tasks can enhance suction efficiency and reduce energy consumption. 4. Avoid using household vacuum cleaners in damp or wet areas, as this can damage the motor and electrical components, leading to potential safety hazards. 5. Adjust the power setting according to the surface you're cleaning. Lower suction is suitable for delicate surfaces, while higher suction works better on carpets or heavy dirt. 6. Before each use, check the vacuum cleaner for any signs of wear or damage, such as frayed cords or loose parts. Regular maintenance not only improves performance but also ensures safe operation. 7. Store the vacuum cleaner in a dry, cool place when not in use. This helps prevent mold, dust buildup, and mechanical issues over time.
