What are the performance indicators of the vacuum cleaner?

Inhalation power: a measure of the ability of the vacuum cleaner to inhale air, in W (watts). Suction power = air volume (air flow) x vacuum degree. The greater the suction power, the greater the suction power.

Energy efficiency: A measure of the power saving capability of the vacuum cleaner. The higher the power saving, the more power saving. It is generally expressed by dividing the suction efficiency by the input power.

Dust removal efficiency: a measure of the ability of a vacuum cleaner to remove dust, generally expressed as a percentage, the higher the cleaning ability, the stronger. In addition to being related to suction power, it is also affected by factors such as brush heads, hoses, and product structure. In addition, the dust removal efficiency of different surfaces (such as floors and carpets) is not the same and needs to be tested separately.

Dust emission: a measure of the secondary pollution generated by the vacuum cleaner, generally expressed as a percentage, the lower the better. Dust emission corresponds to filtration efficiency. Vacuum cleaners with more dust emission and low filtration efficiency are likely to cause dust leakage during use, leading to secondary pollution.

Noise: The vacuum cleaner will make a loud noise when it is running, which will affect the experience of use. The sound may be louder in rooms that are prone to echo, such as the bathroom.
