[0002] With the development of science and technology and the continuous improvement of people's living standards, various household appliances have come into being, such as floor scrubbers, vacuum cleaners, floor washers and other cleaning appliances. This type of cleaning device mainly uses an electric motor to generate negative air pressure in a sealed shell, so that it can suck in dust or garbage to complete cleaning. Its main function is to recycle and clean dust and garbage on the floor, carpets, etc. in the home. Currently, most cleaning devices recycle and separate dust, hair and other garbage by setting a dust cup on the body. Large particles of dust and hair and other garbage enter the dust cup through a floor brush for separation. For example, the utility model patent with publication number: CN203861124U discloses a vacuum cleaning device, including a body, a dust cup, a mop, and a cord reel, the motor is in the motor housing, and an air outlet filter is connected to the motor housing; the dust cup is connected to the body, the dust cup includes a cup body, a cup cover, and a bottom cover, the cup cover includes a dust cup outer cover and a dust cup inner cover, an inner sealing ring is provided between the dust cup inner cover and the cup body, a filter cover, a dust cup filter, and a transparent tube are provided in the dust cup, the dust cup filter is sleeved outside a cyclone separator, and a roller brush is provided on the mop; in this technical solution, garbage, impurities and dust are separated by a dust cup to ensure smooth pipeline operation, avoid damage to the internal structure, and extend the service life, but a single dust cup must separate large particles of dust and hair as well as fine particles of dust, and the separation efficiency of a single dust cup is limited, and the dust and gas separation efficiency is low, which affects the cleaning efficiency. Utility Model Content

The dust, impurities and other garbage on the ground are transported to the dust cup assembly through the extension rod. A telescopic hose can be arranged between the extension rod and the dust cup assembly. The extension rod and the dust cup assembly are connected through the telescopic hose.
