Based on the principle of centrifugal force, it only takes a little manpower to make the mop as dry as if it were in the washing machine. This kind of mop can be used for up to 3 months, but the one-way bearing and base spring are very easy to break and cannot be replaced. It is a disposable product. Now there is an improved type of wringing mop on the market, called "Miaoshen Mop", which is produced by Hefei I Love My Home Daily Necessities Co., Ltd. The biggest difference between this Miaoshen Mop and the Haoshen Mop on the market is that it uses high-quality elastic nylon gears with high hardness and toughness for the single-phase bearings, pedals, and gears which are prone to damage. This effectively solves the trouble of breaking after using for three months. Under standard operation, it will not break even after being used for more than half a year. However, the key is that we need to control the force well during the normal use process and follow the steps on the manual to operate it in a standardized way, so as to extend its service life.
