Vacuum cleaners with full indicator
Dust collector indicator
— an indicator that allows you to determine the fullness of the dust collector without opening the vacuum cleaner.The principle of operation and functionality of such an indicator can be different - from the simplest mechanical device that operates during a critical overflow to an image on the display that displays a specific level of fullness. However, this function makes it easier to monitor the status of the vacuum cleaner. Fill indicators are especially popular in models with bags (see "Dust collector") because, without such equipment, you have to touch the amount of debris - determining how tightly the bag is filled. However, this function can also be used with other types of dust collectors.
