Abstract
A floor tool for a cleaning appliance, the floor tool comprising a cleaner head and a duct assembly. The cleaner head has a suction inlet through which dirt-laden fluid is drawn into the cleaner head and an outlet through which the fluid is discharged. The duct assembly carries the fluid from the outlet to a wand connectable to the duct assembly and comprises a front conduit and a rear conduit. The front conduit is connected to the cleaner head for rotation about a first axis. The rear conduit is connectable to the wand and is rotatable relative to the front conduit about a second axis perpendicular to the first axis. When the floor tool is resting on the floor and the rear conduit extends upwardly, the front and rear conduits arc around and over the second axis.

A floor tool for a vacuum cleaner, the floor tool comprising:
- a cleaner head having an inlet through which dirt-laden fluid is drawn into the cleaner head, and an outlet through which the fluid is discharged;
- and
- a duct assembly configured for connection to a wand and for carrying the fluid from the outlet to the wand,
- wherein the duct assembly comprises a front conduit and a rear conduit, the front conduit is connected to the cleaner head for rotation about a first axis, the rear conduit is connectable to the wand, the rear conduit is rotatable relative to the front conduit about a second axis perpendicular to the first axis, and rotation of the rear conduit causes the rear conduit to move within or about the front conduit, and
- wherein, when the floor tool is resting on the floor and the rear conduit extends upwardly, the front and rear conduits are above the second axis and arc around and over the second axis.
A floor tool for a cleaning appliance, the floor tool comprising:
- a cleaner head having an inlet through which dirt-laden fluid is drawn into the cleaner head and an outlet through which the fluid is discharged;
- and
- a duct assembly configured for connection to a wand and for carrying the fluid from the cleaner head to the wand;
- wherein the duct assembly comprises a front conduit, a rear conduit and two wheels located on either side of the front and rear conduits;
- the front conduit is connected to the cleaner head for rotation about a first axis, the first axis is normal to the plane of the outlet, the rear conduit is connectable to the wand, the rear conduit is rotatable relative to the front conduit about a second axis perpendicular to the first axis, and rotation of the rear conduit causes the rear conduit to move within or about the front conduit,
- wherein rotation of the rear conduit about the second axis causes the rear conduit to move up and down between an upper and a lower position, and rotation of the front conduit about the first axis causes the rear conduit in the upper position to move to the right and left;
- and
- wherein, when the floor tool is resting on the floor and the rear conduit is in the upper position, the front and rear conduits are above the second axis and arc around and over the second axis.
A vacuum cleaner comprising a wand connected to a floor tool, the floor tool comprising:
- a cleaner head having an inlet through which dirt-laden fluid is drawn into the cleaner head, and an outlet through which the fluid is discharged;
- and
- a duct assembly configured for connection to the wand and for carrying the fluid from the outlet to the wand,
- wherein the duct assembly comprises a front conduit and a rear conduit, the front conduit is connected to the cleaner head for rotation about a first axis, the rear conduit is connectable to the wand, the rear conduit is rotatable relative to the front conduit about a second axis perpendicular to the first axis, and rotation of the rear conduit causes the rear conduit to move within or about the front conduit, and
- wherein, when the floor tool is resting on the floor and the rear conduit extends upwardly, the front and rear conduits are above the second axis and arc around and over the second axis,
- wherein movement of the wand in an up and down motion causes the rear conduit to move up and down, and twisting of the wand to the right and left causes the front conduit to rotate about the first axis such that, when the rear conduit is in the upper position, the rear conduit is caused to move to the right and left.
A vacuum cleaner comprising a wand connected to a floor tool, the floor tool comprising:
- a cleaner head having an inlet through which dirt-laden fluid is drawn into the cleaner head and an outlet through which the fluid is discharged;
- and
- a duct assembly configured for connection to the wand and for carrying the fluid from the cleaner head to the wand;
- wherein the duct assembly comprises a front conduit, a rear conduit and two wheels located on either side of the front and rear conduits;
- the front conduit is connected to the cleaner head for rotation about a first axis, the first axis is normal to the plane of the outlet, the rear conduit is connectable to the wand, the rear conduit is rotatable relative to the front conduit about a second axis perpendicular to the first axis, and rotation of the rear conduit causes the rear conduit to move within or about the front conduit,
- wherein rotation of the rear conduit about the second axis causes the rear conduit to move up and down between an upper and a lower position, and rotation of the front conduit about the first axis causes the rear conduit in the upper position to move to the right and left;
- and
- wherein, when the floor tool is resting on the floor and the rear conduit is in the upper position, the front and rear conduits are above the second axis and arc around and over the second axis,
- wherein movement of the wand in an up and down motion causes the rear conduit to move up and down, and twisting of the wand to the right and left causes the front conduit to rotate about the first axis such that, when the rear conduit is in the upper position, the rear conduit is caused to move to the right and left.
