PROBLEM TO BE SOLVED: To provide a self-travelling air-cleaning machine capable of more efficiently and effectively cleaning air and suppressing an increase in power consumption.SOLUTION: A traveling part 2 and an air cleaning part 3 are separable. By running only the traveling part 2, a contamination map for a room is made up and maintained to clean air efficiently based on the contamination map for the room.COPYRIGHT: (C)2014,JPO&INPIT【課題】より効率的、効果的に空気清浄を行うことができ、かつ、消費電力の増加も抑制できる自走式空気清浄機を提供する。【解決手段】走行部2と空気清浄部3とを分離可能とし、走行部2のみを走行させ、部屋内の汚れマップを作成、保持し、部屋内の汚れマップに基づいて、効率的に空気を清浄する。【選択図】図4
