Why does the Robot Vacuum E5 consume power fast while vacuuming?

After the main unit completes charging and is left for an extended period, there will be a phenomenon of rapid battery depletion during the first few minutes of cleaning. This is normal, and the battery consumption will return to normal after a few minutes. Additionally, when using the strong suction mode for cleaning, the battery will deplete faster.
In addition, the Xiaomi Robot Vacuum E5 will also consume power when it is constantly on the charging dock. When the main unit is constantly on the charging dock, the power is supplied from the dock to the main unit. During this time, to maintain optimal performance, the battery enters a sleep state and the power consumption is very low.
