1 Introduction

A vacuum robot is becoming an essential equipment for a typical family. The robot can vacuum the hard floors and carpets, and mop the hard floors automatically, saving a lot of clearing efforts and time for us. More and more features are equipped in the vacuum robot to be effective. The sucking power and the side rolling brushes are the key features to improve the effectiveness of the cleaning. Smart sensors for obstacle avoidance and floor type identification are essential parts of smart operation. All these features require power to operate. The battery capacity needs to keep the operation for several hours for a complete clearing cycle. Some advanced features including mopping and the automatic drying to avoid molding put more challenges to the power requirements and system thermal design.
