In addition, there was a problem in that health deteriorated due to strain on the joints due to taking postures such as squatting or bending the waist for a long time.

In order to solve this problem, a rolling mop capable of cleaning the floor without lowering one's posture has recently been widely used. The rolling mop is a combination of a rolling pin and a head part, and cleaning can be performed using a mop fixed to the bottom of the head part. Since the length of the push rod is formed long, there is an advantage in that the user can perform cleaning without having to lower his/her posture.

However, in order to perform cleaning using such a rolling mop, the lower surface of the head unit must be moved in close contact with the floor to be cleaned. In order to bring the lower surface of the head part into close contact with the floor, the pressing force from above must be high. Users who use the rolling mop push the rolling rod in an inclined state rather than perpendicular to the floor. There is a problem that needs to be pushed.

Meanwhile, the United Nations categorizes an aged society as one with 14% or more of the population aged 65 or older, and a super-aged society as one with 20% or more. It is becoming. In the case of the elderly, it is difficult to clean by lowering the posture due to weakened joints, and the force that can be exerted is very weak due to muscle weakness, so it is difficult to achieve sufficient cleaning effect using a conventional rolling mop.
