Abstract
    Conditions of sucking up and moving of robot on the wall are given. Geometrical and physical factors restricting elevation ratio of wall-cleaning robot body are discussed. Methods are given to improve the elevation ratio. Designing method of vacuum-sorbing and pulling forces is studied according to the condition and requirement of elevation ratio.
