Abstract: A fan assembly includes a base, a body including an air inlet, impeller and motor driving the impeller to draw an air flow through the air inlet, an air outlet and an interior passage conveying air to the air outlet and extending about an opening through which air from outside the fan assembly is drawn by air emitted from the air outlet. A motorized oscillation mechanism housed within the base oscillates the body relative to the base about an axis and includes a second motor, a drive member driven by the second motor, and a driven member which is driven by the drive member to rotate relative to the base about the axis. The body is mounted on the driven member for rotation therewith. Interlocking members retain the body on the driven member and serve to guide tilting movement of the body relative to the base about a tilt axis.

Abstract: A cleaner head comprising a main body rotatably coupled to a neck, and a locking arrangement operable to permit rotation of the main body relative to the neck when the cleaner head is positioned on a surface and to prevent rotation of the body relative to the next when the cleaner head is lifted off a surface. The locking arrangement therefore stops the cleaner head from rotating undesirably when the cleaner head is lifted away from a cleaning surface.
