Abstract

A gutter cleaner comprising: a fan assembly; a guide configured to at least partially support the fan assembly on a gutter, wherein the guide comprises a skid configured to slide along the gutter; a handle coupled to the fan assembly at a location adjacent to a first axial end of the handle; and a battery port disposed at a location adjacent to a second axial end of the handle, the second axial end of the handle being opposite the first axial end of the handle, wherein the gutter cleaner is supportable via the handle by an operator located at an elevation below the gutter, and wherein the gutter cleaner has an approximately neutral operational buoyancy.

First claim

What is claimed is:

1. A gutter cleaner comprising:
a fan assembly;
a guide configured to at least partially support the fan assembly on a gutter, wherein the guide comprises a skid configured to slide along the gutter;
a handle coupled to the fan assembly at a location adjacent to a first axial end of the handle;
a battery port disposed at a location adjacent to a second axial end of the handle, the second axial end of the handle being opposite the first axial end of the handle; and
a processor configured to control a speed of the fan assembly during operation in response to a sensed condition, the sensed condition comprising an angular orientation of at least one component of the gutter cleaner,
wherein the gutter cleaner is supportable via the handle by an operator located at an elevation below the gutter, and wherein the gutter cleaner has an approximately neutral operational buoyancy.

2. The gutter cleaner of claim 1 , wherein the handle is coupled to the fan assembly through a multi-axis connector comprising at least one of:
an adjustable, multi-axis interface, and
at least a first connector and a second connector disposed at different angular orientations.

3. The gutter cleaner of claim 1 , wherein a length of the handle is adjustable.

4. The gutter cleaner of claim 1 , further comprising an inlet cover disposed upstream of the fan assembly, wherein the inlet cover defines a curved profile.

5. The gutter cleaner of claim 1 , wherein the handle is engageable with a harness configured to be coupled to the operator.

6. The gutter cleaner of claim 1 , wherein the guide comprises a quick connect interface, and wherein the guide is interchangeable with a plurality of different-style guides.

7. The gutter cleaner of claim 1 , wherein the guide comprises a tapered lip.

8. The gutter cleaner of claim 1 , wherein the guide is shaped such that the gutter cleaner extends into the gutter by no greater than 10% of a vertical elevation of the gutter.

9. The gutter cleaner of claim 1 , wherein the fan assembly includes a fan configured to generate airflow to remove debris from the gutter, wherein the fan assembly is configured to generate airflow at a mass flow rate of at least 0.2 kg/s and velocity of at least 30 m/s during operation.

10. The gutter cleaner of claim 9 , wherein the processor is configured to modulate a speed of the fan during operation of the gutter cleaner.

11. The gutter cleaner of claim 1 , wherein the gutter cleaner is configured to generate an adjustable, variable speed airflow to blow debris from the gutter.

12. A method of cleaning a gutter with the gutter cleaner of claim 1 , the method comprising:
positioning the gutter cleaner adjacent to the gutter;
generating an airflow with the fan assembly; and
moving the gutter cleaner along a length of the gutter to blow debris therefrom.

13. The method of claim 12 , wherein the step of moving the gutter cleaner is performed by translating the guide along the length of the gutter.

14. The method of claim 12 , wherein the step of positioning the fan assembly is performed prior to the step of generating airflow with the fan assembly.

15. The method of claim 12 , wherein the step of positioning the fan assembly is performed by pivoting the fan assembly from a first elevation below the gutter to a second elevation above the gutter.

16. The method of claim 12 , further comprising:
selecting an angular displacement between the fan assembly and the handle prior to the step of positioning the fan assembly.

17. The method of claim 12 , further comprising:
coupling the handle to a harness coupled to an operator of the gutter cleaner.

18. The method of claim 12 , further comprising:
selecting an angular orientation of the fan assembly with respect to the handle; and
selecting a length of the handle,
wherein the selected angular orientation and length of the handle are selectable such that an operator is positioned at a vertical elevation below the gutter.
