The suction power of a vacuum cleaner is an important factor to consider when buying one. Suction power is measured in different units, including Pascals (Pa), kilopascals (kPa), air watts (AW), and watts (W) . The best suction power for a vacuum cleaner depends on the type of surface you will be cleaning and the type of debris you will be picking up. Here are some guidelines to consider:

• Bare floors: For cleaning bare floors, a vacuum cleaner with a suction power of at least 200 AW is recommended.

• Carpeted floors: For cleaning carpets, a vacuum cleaner with a suction power of at least 250 AW is recommended.

• Pet hair: If you have pets, look for a vacuum cleaner with a suction power of at least 300 AW to effectively pick up pet hair.

• Heavy debris: If you need to pick up heavier debris like rice or gravel, look for a vacuum cleaner with a suction power of at least 5000 Pa.

Its important to note that suction power is not the only factor that determines a vacuum cleaners cleaning ability. Other factors like airflow, water lift, and motor power also play a role. Additionally, a vacuum cleaners suction power can be affected by factors like clogging of the filter.

Overall, when looking for a vacuum cleaner with good suction power, its important to consider the type of surface you will be cleaning and the type of debris you will be picking up. Look for a vacuum cleaner with a suction power that meets your needs and has good overall performance across all surface types.
