The design of the Siemens sensor cruiser focuses on perfection of comfort and maximal ease of operation. The robot vacuum cleaner consists of two parts: the mobile robot and the docking station. The integrated touch and optical sensors detect barriers and steps and help the robot navigate around them safely. An additional dust particle sensor analyses the degree of dirtiness and chooses automatically the appropriate cleaning program. The rounded shape and the low height with additional protectors on the topside guarantee mobility and avert it from getting stuck. When the dust container of the robot is full or the energy level gets low, the robot returns itself to the docking station where the dust is removed automatically and the battery is recharged.
