Cleaning device

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.
