Vacuum cleaners with charge level indicator

Charge level indicator

— the presence of an indicator in the vacuum cleaner that displays the current battery level. The design and functionality of such an indicator may be different. Often the simplest LED indicators are used, allowing only an approximate estimate of the remaining energy. Also, note that the indicator may not be placed on the body of the tool, but on the battery itself. Nevertheless, this feature, anyway, provides additional convenience, makes it easier to monitor the state of the battery and reduces the risk of being left with a dead battery at the wrong time.
