Problems solved by technology

Although the main body is arranged such that the center of gravity of the main body is in a position in which the main body will tend to return itself to the upright position, there is still a danger that the main body cannot return to the upright position, for example when it leans against the When positioning a wall or other object on a ground surface

Embodiment Construction

[0057] Figures 1 to 4 An external view of a cleaning appliance in the form of a vacuum cleaner 10 is shown. The vacuum cleaner 10 is of a cylinder or canister type. Generally, the vacuum cleaner 10 includes a separation device 12 for separating dirt and dust from an airflow. The separation device 12 is preferably in the form of a cyclonic separation device and comprises an outer casing 14 having a substantially cylindrical outer wall 16 . The lower end of the outer box 14 is closed by a curved base 18 which is pivotally attached to the outer wall 16 . A motor-driven fan unit for generating suction to draw spoil-laden air into the separation device 12 is housed in a roller assembly 20 located behind the separation device 12 . The rolling assembly 20 includes a main body 22 and two wheels 24, 26 rotatably connected to the main body 22 for engaging a ground surface. An inlet duct 28 located below the separation device 12 conveys dirt-laden air into the separation device 12 a...

Abstract

A cleaning appliance comprises a separating apparatus (12) for separating dirt from a dirt-bearing fluid flow, a duct (28) moveable relative to the chassis for conveying the fluid flow to the separating apparatus, a floor engaging steering member (40), and a control mechanism (42, 44, 58) for moving the steering member relative to the chassis in response to movement of the duct relative to the chassis.

Description

technical field [0001] The invention relates to a cleaning appliance. Background technique [0002] Cleaning appliances such as vacuum cleaners are well known. Vacuum cleaners are either of the "upright" type or of the "canister" type (called canister or bucket machines in some countries). A cylinder vacuum cleaner typically consists of a main body containing a motor-driven fan unit for drawing a dirt-entrained fluid stream into the vacuum cleaner, such as a cyclone or a bag for removing the dirt and dust are separated from the fluid stream. A dirt-entrained fluid flow is introduced into the body through a suction hose and wand assembly connected to the body. The main body of the vacuum cleaner is dragged along with the hose as the user moves around the room. A cleaning tool is attached to the distal end of the hose and wand assembly. [0003] For example, GB 2,407,022 describes a cylinder vacuum cleaner having a frame supporting cyclonic separation equipment. The vacu...
