1. When using the vacuum cleaner, make sure to empty the dust from the filter bag or clean the filter regularly to maintain optimal performance.

2. It's important to lubricate the vacuum cleaner’s shaft periodically and replace the brush with one of the same quality and grade to ensure smooth operation and extend the machine's lifespan.

3. Always inspect the vacuum’s air duct, nozzle, hose, and inlet for any blockages or foreign objects. Choosing the right nozzle for different cleaning tasks can enhance suction efficiency and help save energy.

4. Avoid using a household vacuum cleaner in wet areas or on damp surfaces, as this may damage the motor or cause electrical hazards.

5. Adjust the suction power according to the surface you're cleaning. Using the appropriate setting not only improves cleaning results but also reduces unnecessary energy consumption.

6. Before each use, check the power cord and plug for any signs of wear or damage. If anything seems wrong, stop using the vacuum immediately and have it repaired by a qualified technician.

7. Store the vacuum cleaner in a dry and cool place when not in use. This helps prevent mold, rust, and other forms of damage that could affect its performance over time.

8. Never pull the cord to unplug the vacuum. Always grasp the plug and gently remove it from the socket to avoid damaging the wiring or the outlet.
