Description

Mop cleaner {wet duster}

The present invention relates to a mop cleaner, and more particularly, to a mop cleaner for wiping a floor in an apartment, a general house, an office, and the like.

Unlike other countries, Korea's housing culture is to live off its shoes and sleep on the floor, so the floor must be kept clean. Typically, most homes use vacuum cleaners to clean the floor. Such a vacuum cleaner may use a vacuum to remove dust or small foreign matters accumulated on the floor. However, the vacuum cleaner can remove dust or foreign matter that is easily separated from the bottom, but dust or oil stuck to the floor, food waste, etc. cannot be removed. As such, dust or oil, food waste, etc., which could not be removed by a vacuum cleaner, had to be removed using a mop.

By the way, when cleaning the floor using a mop did not give a strong force to the mop could not remove the old time stuck on the floor. In addition, in the prone state to hold the mop by hand to clean the floor, so cleaning the mop used to pain in the lower back and arms. In other words, mop cleaning required hard labor, and therefore, the elderly, pregnant women, and those with back pain could not clean the mop. In particular, these days, the spread of large apartments, the difficulty of cleaning the mop has been highlighted.

Based on these problems, many companies are selling and selling a mop cleaner consisting of an elongated handle bar, and a detachable part for attaching and detaching the mop at the bottom of the handle bar.

However, in the case of such a mop cleaner, when the mop is dirty or the moisture absorbed in the mop disappeared because it had to be replaced with a new mop often caused inconvenience. In addition, since the detachable part to which the mop is attached has a large area, the force applied to the mop cleaner is dispersed. That is, the pressure per unit area applied to the floor by the mop was forced to be small, and thus could not effectively remove the bundled time of the floor.

The present invention has been made to solve the above problems, an object of the present invention is to provide a mop cleaner that does not need to replace the mop during cleaning.

Still another object of the present invention is to provide a mop cleaner that can apply a large force to the floor to effectively remove the bundled dust.
