CLEANING MATTERS Our cleaning activities are not only about hygiene issues. We also clean to organize our surroundings, and ourselves. In that sense, It is ironical to see that various kinds of cleaning devices make our cleaning activities and surroundings complex. For example, robot vacuum cleaner is useful device for general house cleaning. When spot cleaning is needed, however, robot vacuuming is not a good solution. That is why we need both handy and robot vacuum cleaner.
