After a full charge, if the robot vacuum has been left idle for an extended period, it can show a rapid drop in battery level during the first few minutes of cleaning. This is normal behavior, and power consumption will stabilize shortly after.
Additionally, using the high-power cleaning mode will also cause faster battery consumption.
If the robot vacuum is cleaning an area with many obstacles, corners, or carpeted surfaces, it will consume more power due to increased navigation effort and suction requirements.
Constantly detecting and avoiding obstacles requires more processing and movement, which increases energy usage.
Dirty filters, brushes, or wheels can make the vacuum work harder, leading to faster battery drain. Regular maintenance can help reduce power consumption.
