Samsung patents vacuum cleaner that picks the healthiest battery to run

This patent describes a cordless vacuum cleaner equipped with multiple internal batteries. The device uses a processor to check the condition of each battery and selects the one with the longest remaining life to power the suction motor, while pausing the others.

Why it mattersThis approach aims to extend the overall lifespan of the vacuum's power system by ensuring the most durable battery is used first, rather than draining all cells equally.
