[0002] Carpets are a common household item used in many families and offices nowadays. Although they are comfortable and good-looking when in use, if not cleaned in time, they may breed bacteria, which is not beneficial to human health. The traditional method is to send the carpet to a special place for carpet cleaning, wash it with water and then dry it. However, this is time-consuming and laborious, and the cleaning device used in this process is very large. It is necessary to put the entire carpet into the mixing drum, which is very troublesome. When only a small part of the carpet is dirty, it is impossible to clean and dry the local dirt, and the use effect is not good.

[0003] Carpet cleaning machines solve the above problems well. They can spray clean water to clean dirty areas and use the suction effect of negative pressure to suck dirty water and small particle dust into the machine, completing the function of local cleaning, and are widely favored by people. However, the carpet cleaning machines currently on the market cannot handle hair and large particle garbage. It is easy for the hair to wind around the roller brush, and the large particle garbage is also easy to block the suction port, thus affecting the normal use of the carpet cleaning machine.
