Surface cleaning apparatus
The present disclosure provides a surface cleaning apparatus that includes a headlight or other light source that selectively illuminates upon the occurrence of a predetermined condition. The headlight turns on to emit light when the surface cleaning apparatus us turned on, and emits light in a different color when cleaning fluid is dispensed. Methods for operating a headlight or light source are also disclosed.
1. A surface cleaning apparatus for cleaning a floor surface, comprising:
a base adapted for movement over a surface to be cleaned and comprising:
a suction nozzle defining a dirty inlet to a recovery pathway;
a brushroll;
a fluid distributor to deliver cleaning fluid to at least one of the brushroll and the surface to be cleaned; and
a headlight to illuminate the surface to be cleaned, the headlight capable of emitting light in at least a first color and a second color; and
an upright body pivotally mounted to the base and comprising:
a handle;
a power input control to turn the surface cleaning apparatus on and off; and
an actuator to control the delivery of cleaning fluid from the fluid distributor;
a controller on one of the base and the upright body, the controller operable to:
turn the headlight on to emit light in the first color when the power input control is pressed to turn the surface cleaning apparatus on; and
control the headlight to emit light in the second color when the actuator is pressed to deliver cleaning fluid from the fluid distributor.
2. The surface cleaning apparatus of claim 1 , wherein the controller is operable to control the headlight to emit light in the first color when the actuator is released to stop delivery of cleaning fluid from the fluid distributor.
3. The surface cleaning apparatus of claim 2 , wherein the actuator comprises a trigger on a handgrip of the handle.
4. The surface cleaning apparatus of claim 1 , wherein the power input control comprises a button on the handle.
5. The surface cleaning apparatus of claim 1 , wherein the headlight is configured to emit light in a first state when the power input control is pressed to turn the surface cleaning apparatus on and to emit light in a second state when the actuator is pressed to deliver cleaning fluid from the fluid distributor.
6. The surface cleaning apparatus of claim 1 , wherein the first state is a steady state and the second state is an animated state.
7. The surface cleaning apparatus of claim 1 , wherein the headlight comprises a light emitting diode module with multiple LED chips, including at least one white LED chip and at least one non-white LED chip.
8. The surface cleaning apparatus of claim 7 , wherein the controller is operable to:
power the at least one white LED chip when the power input control is pressed to turn the surface cleaning apparatus on; and
power the at least one non-white LED chip when the actuator is pressed to deliver cleaning fluid from the fluid distributor.
9. The surface cleaning apparatus of claim 1 , wherein the headlight comprises a light source internal to the base and the base comprises a light pipe configured to transmit a portion of the light emitted by the light source to an area exterior of the base.
10. The surface cleaning apparatus of claim 1 , comprising:
a pump in fluid communication with the fluid distributor; and
a brushroll motor coupled with the brushroll to drive the brushroll;
wherein the pump and brushroll motor are mounted in the base.
11. A surface cleaning apparatus comprising:
a base adapted for movement over a surface to be cleaned and comprising:
a suction nozzle defining a dirty inlet to a recovery pathway;
a brushroll;
a fluid distributor to deliver cleaning fluid to at least one of the brushroll and the surface to be cleaned;
a light source internal to the base and positioned to emit light within an interior of the base, the light source capable of emitting light in at least a first color and a second color; and
a light pipe configured to transmit a portion of the light emitted by the light source to an area exterior of the base; and
an upright body pivotally mounted to the base and comprising:
a handle;
a power input control to turn the surface cleaning apparatus on and off; and
an actuator to control the delivery of cleaning fluid from the fluid distributor;
a controller on one of the base and the upright body, the controller operable to:
turn the light source on to emit light in the first color when the power input control is pressed to turn the surface cleaning apparatus on, with the light in the first color transmitted to the area exterior of the base by the light pipe; and
control the light source to emit light in the second color when the actuator is pressed to deliver cleaning fluid from the fluid distributor, with the light in the second color transmitted to the area exterior of the base by the light pipe.
12. The surface cleaning apparatus of claim 11 , wherein:
the base comprises a base housing and a cover attached to the base housing, the brushroll partially enclosed by the cover; and
the cover comprises the light pipe.
13. The surface cleaning apparatus of claim 12 , wherein the light pipe is a solid structure integrally molded with the cover.
14. The surface cleaning apparatus of claim 12 , wherein the light pipe is laterally-elongated along a width of the cover.
15. The surface cleaning apparatus of claim 11 , wherein the controller is operable to control the light source to emit light in the first color when the actuator is released to stop delivery of cleaning fluid from the fluid distributor.
16. The surface cleaning apparatus of claim 15 , wherein the power input control comprises a button on the handle and the actuator comprises a trigger on a handgrip of the handle.
17. The surface cleaning apparatus of claim 11 , wherein the light source is configured to emit light in a first state when the power input control is pressed to turn the surface cleaning apparatus on and to emit light in a second state when the actuator is pressed to deliver cleaning fluid from the fluid distributor.
18. The surface cleaning apparatus of claim 17 , wherein the first state is a steady state and the second state is an animated state.
19. The surface cleaning apparatus of claim 11 , wherein the light source comprises a light emitting diode module with multiple LED chips, including at least one white LED chip and at least one non-white LED chip, wherein the controller is operable to:
power the at least one white LED chip when the power input control is pressed to turn the surface cleaning apparatus on; and
power the at least one non-white LED chip when the actuator is pressed to deliver cleaning fluid from the fluid distributor.
20. The surface cleaning apparatus of claim 11 , comprising:
a pump in fluid communication with the fluid distributor; and
a brushroll motor coupled with the brushroll to drive the brushroll;
wherein the pump and brushroll motor are mounted in the base.
