Abstract
This report tells how much energy is consumed for wiping with a damp cloth in housework. The experiment was done by two experimentalists using Douglas bag, in Feb. 1966. The author experimented to find the most efficient method by changing posture, working height and speed.
Three types of working postures, kneeling down, squatting down and standing pose using mop were tested. Rate of energy consumption shows standing pose to be the lowest, and squatting down consumes 30 % more energy than kneeling down. For working level 80 cm, above the floor, was the most efficient height. As for working speed, about 60 times/min and 120 times/ min were the most effective speed. The latter is appropriate for light wiping.
