[0002] When showering at home, people often face the problem of not being able to scrub their backs properly. Because it's difficult to reach the back with both hands, the back is not cleaned thoroughly, and dirt residue can affect skin health. Manually scrubbing the back is not only strenuous, but it's also difficult to control the pressure and angle, easily leading to uneven application of force or incomplete cleaning.

[0003] Traditional bath towels and similar tools, due to their simple design, require ample space for operation and offer less than satisfactory cleaning results. Current back-scrubbing tools on the market have many limitations, failing to effectively solve the inconvenience of scrubbing the back while showering at home and failing to meet people's demand for convenient and efficient back scrubbing. Therefore, developing a high-performance back-scrubbing machine is of significant practical importance. Utility Model Content

[0004] The main purpose of this utility model is to provide a back-rubbing machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
