When we clean with water wide spaces such as garden, entry way and stairs made of marble, we spray waterthrough a hose and sweep the floor with a broom. The process of cleaning with water is the repetition of spraying water through a hose and sweeping the floor with a broom. Such process is inefficient in cleaning and leads to wasting water as more and appropriate amount of water is sprayed through a hose. How aboutan easier and more convenient way of cleaning if you had to one by one spray water through a hose and clean with a broom?
