Sanitary cleaning is a headache for everyone and every family. In order to clean up, I have tried large manual mops, spin dehydration mops, sweeping robots, steam mops, sweeping and mopping robots, and sweeping and mopping washing machines. vacuum cleaner etc. Each cleaning and sanitation tool has its own advantages and disadvantages. Ordinary mops are economical, but laborious, not easy to clean, etc. The sweeper is easy to use, but there are not many obstacles in the home, and the corners are not clean. Steam mop Stubborn stains are easy to clean, and the germicidal effect is good. But also a bit laborious. The vacuum cleaner can clean solid ash and granular ash. Most vacuum cleaners are larger in size and have a larger suction head. It is not easy to clean the dust in the corners. Can't be cleaned because of the size.
