Embodiment Construction

[0042] refer to Figures 1a to 2b , the structure of the prior art vacuum cleaner can be seen. A vacuum cleaner, generally designated by reference numeral 1 , comprises a main body 2 , a user-operated handle 3 and a cleaner head 4 . A cleaner head 4 is pivotally mounted to the lower end of the main body 2 and is used, in use, for treating ground surfaces. The ground-facing side of the lower part of the cleaner head 4 has an air inlet slot 11 .

[0043]The vacuum cleaner 1 houses a motor and a fan (not shown in these figures) for generating a suction air flow. The main body 2 houses separating means 6 for separating dirt, dust and other debris from the dirty airflow drawn into the cleaner 1 by the fan and motor.

[0044] In this prior art vacuum cleaner, the separating device 6 is a cyclone in which dirt and dust are centrifugally separated from the air flow. The cyclonic separating device 6 comprises two stages of cyclones arranged in series with each other. The first sta...

Abstract

The present invention relates to a surface treating appliance, such as a vacuum cleaner having a fluid flow path extending between at least one fluid inlet and at least one fluid outlet wherein at least a part of the fluid flow path is housed within a releasable portion of the surface treating appliance.

Description

technical field [0001] The present invention relates to a surface treatment appliance, such as a vacuum cleaner. More particularly, the present invention relates to a surface treating appliance having a fluid flow channel extending between at least one fluid inlet and at least one fluid outlet, wherein at least a portion of the fluid flow channel is received in a releasable portion of the surface treating appliance . Background technique [0002] Surface treatment appliances such as vacuum cleaners are known. Most vacuum cleaners are "upright" or "canister". A typical vacuum cleaner includes a main body that houses the main components of the vacuum cleaner, such as the motor and fan used to draw dirty air into the machine and the separator used to separate dirt, dust and other debris from the dirty airflow drawn by the fan device. [0003] Vacuum cleaners are known which have at least one and usually a plurality of alternative airflow channels between an air inlet and an...
