Abstract: Provided are a cleaning robot and a method for traveling along an edge, and a readable medium. The cleaning robot includes a body, where a rolling brush and a side brush are provided at a bottom of the body, the rolling brush and the side brush are transversely arranged at a front end of the cleaning robot, and one end of the rolling brush and the side brush are respectively arranged close to edges of two sides of the body; the cleaning robot further includes a control module and a ground medium identification sensor for detecting a type of a work surface, where the ground medium identification sensor sends a detection signal to the control module, and the control module controls the cleaning robot to travel along an edge with one side edge of the body according to the detection signal.

Abstract: A cyclone separation device (102, 202) and a cyclone vacuum cleaner (100, 200) mounted with the device. A first cyclone separation unit in the cyclone separation device (102, 202) comprises a dust bucket (10) and a mesh filter (7) with air holes (7a). Airflow enters the first cyclone separation unit to undergo first gas-solid separation. The airflow after the separation enters a second cyclone separation unit through the air holes (7a) of the mesh filter (7). A filter in the second cyclone separation unit comprises a plurality of cyclone barrels (31). An upper end and a lower end of the cyclone barrel (31) are open. A first air inlet (31a) and a second air inlet (31b) are disposed on a side wall of the cyclone barrel (31). The airflow (41a, 41b) after the gas-solid separation enters the first air inlet (31a) and the second air inlet (31b) through a first airflow passage and a second airflow passage respectively, is mixed in the cyclone barrel (31), and then undergoes second gas-solid separation.
