Abstract:
A surface cleaning apparatus comprises a dirt inlet, a handle, a cyclonic cleaning unit comprising a plurality of cyclones and at least one dirt collection chamber, each of the plurality of cyclones having an outer wall, an interior, a fluid inlet downstream from the dirt inlet and a fluid outlet, the at least one dirt collection chamber having an outer wall and an interior, wherein the surface cleaning apparatus is constructed such that the interior of the at least one dirt collection chamber is visible from a position exterior to the surface cleaning apparatus and a fluid flow motor. The surface cleaning apparatus may have a filter with a housing that is at least partially transparent.
Abstract:
A surface cleaning apparatus comprises a dirt inlet, a handle, a cyclone separator having an outer wall, a fluid inlet downstream from the dirt air inlet and a fluid outlet, a plate having a cyclone chamber surface and positioned to substantially divide the cyclone separator into a cyclone chamber and a dirt collection chamber, the plate being removably mounted in the cyclone separator, a passage extending between the cyclone chamber and the dirt collection chamber and a fluid flow motor.
Abstract:
A surface cleaning apparatus comprises a dirt inlet, a handle, a cyclone separator having an outer wall, a top, a fluid inlet downstream from the dirt air inlet and a fluid outlet, a screen positioned around the fluid outlet such that fluid exiting the cyclone separator passes through the screen and the screen is removable through the top of the cyclone separator, and, a fluid flow motor.
Abstract:
A frame assembly comprising a frame having a front and a panel to receive at least one piece of art, the panel having a front face having at least one first engagement member affixed thereon; and, at least one second engagement member adapted to be secured to a rear surface of a piece of art, wherein the first and second engagement members comprise male and female engagement members. A framed piece of art and a method or removably affixing one or more pieces or art to a frame is also provided.
Abstract:
A household apparatus for treating water has a water treatment reactor; a dispense water path extending from the water treatment reactor to a dispenser whereby treated water produced in the water treatment reactor exits the apparatus by the dispenser; a filter removably mounted in the dispense water path; and, a sensor, (which may be a timer, a flow rate sensor and/or a back pressure sensor) for monitoring the flow of a treated water through the filter, the apparatus issuing a signal advising a user to change the filter when the time for the treated water to flow through the filter exceeds a predetermined value.
Abstract:
A surface cleaning apparatus having an outer surface and comprises a dirt inlet, a handle, a cyclone separator having a cyclone separator interior and an outer wall having an inner surface, the cyclone separator comprising a cyclone chamber and a dirt collection chamber, the dirt collection chamber and the cyclone chamber each having an outer wall, the surface cleaning apparatus is constructed such that the cyclone separator interior is visible from a position exterior to the surface cleaning apparatus, an illumination member positioned to provide illumination to at least a portion of the cyclone separator interior, and a fluid flow motor.
Abstract:
A portable vacuum cleaner having at least first and second cleaning stages wherein the first cleaning stage has a dirt collection member and the second cleaning stage comprises a plurality of cyclones and at least one dirt collection chamber, wherein the first and second cleaning stages are emptied separately. One cleaning stage can be removably mounted from the vacuum cleaner without removing another cleaning stage.
Abstract:
A cleaning head for a surface cleaning apparatus comprises a housing having a surface contacting surface, a first inlet provided in the surface contacting surface and in communication with a first treatment stage and a second inlet spaced from the first inlet and provided in the surface contacting surface and, in use, in communication with a second treatment stage and a source of suction.
Abstract:
