Vacuum strength is commonly rated in terms of suction power or air wattage. This rating measures the amount of suction that a vacuum cleaner can generate. The higher the suction power or air wattage, the stronger the vacuum cleaner's ability to pick up dirt, dust, and debris.

To find out the vacuum strength rating of a particular vacuum cleaner, you can check the product's specifications or user manual. Alternatively, you can also look for reviews or comparisons of different vacuum cleaners online, as they often include information about the suction power or air wattage.

It's important to note that while suction power is one aspect of a vacuum cleaner's cleaning performance, other factors such as cleaning attachments, filtration system, and brush roll design also contribute to its overall effectiveness in picking up dirt and maintaining clean floors.
