"Triangle" is the optimum shape for robot vacuum cleaners.(ロボット掃除機の正解は▲でした。English篇)【パナソニック公式】

Almost half of the owners of robot vacuum cleaners we interviewed said they were "unhappy with cleaning performance around the corners of rooms."Panasonic has solved this problem using the "Reuleaux Triangle," named after the German engineer Franz Reuleaux.This is the smallest fixed-width shape that can be rotated to cover almost the entire surface area within a rectangle. It can reach the corners easily due to its triangular shape.Furthermore, the side brushes and vacuum intake are arranged near the front edge of the cleaner for effective vacuuming. Panasonic has created a triangular robot vacuum cleaner that can clean a room thoroughly, right to the corners.
