Abstract: A floor brush comprising: a housing defining a dust suction cavity and including an end cover at one side thereof; a rolling brush assembly comprising a rolling brush able to pass through an opening of the end cover to be arranged in the dust suction cavity; a biasing assembly, wherein the rolling brush assembly is mounted biasedly relative to the housing by means of the biasing assembly; and an automatic locking apparatus having a release position and a locking position, wherein at the locking position, the automatic locking apparatus fixes the rolling brush assembly in position, and at the release position, the rolling brush assembly can be taken out axially outward from the housing under the effect of a biasing force. This floor brush avoids the need to use a tool to (dis)assemble the rolling brush, achieving the objects of simple structure and convenient (dis)assembly.

Abstract: A cleaning device with a sealing member provided in a region of connection of a body part and a dust collection component of the cleaning device. A cross section of an elastic force application portion of the sealing member being formed in an arc shape, thereby enabling a good sealing effect while also facilitating installation and removal of the dust collection component. The sealing member has a two-layer elastic wall structure and is therefore not likely to deform even with long-term use. An alignment structure between the dust collection component and a device body further avoids problems such as rocking and shifting during installation of the dust collection component; improves a sealing structure between a handle and the device body, facilitates installation and removal of the handle; and improves an installation connection structure of a cleaning fluid storage tank.
