Abstract

A gutter cleaner comprising: a fan assembly configured to generate airflow to blow debris from a gutter; a cage at least partially disposed around the fan assembly and configured to prevent ingress of clogging debris into the fan assembly; and at least one wheel configured to roll along the gutter and at least partially support the gutter cleaner, wherein the at least one wheel is non-powered, and wherein the gutter cleaner is self-aligning on the gutter.

First claim

What is claimed is:

1. A gutter cleaner comprising:
a fan assembly comprising a fan configured to generate airflow to blow debris from a gutter;
a cage at least partially disposed around the fan and configured to prevent ingress of clogging debris into the fan assembly; and
at least one wheel configured to roll along the gutter and at least partially support the gutter cleaner,
wherein the at least one wheel is non-powered,
wherein the cage comprises a plurality of openings distributed around the fan,
wherein the cage comprises a primary opening that passes the airflow generated by the fan through the cage to the gutter, and
wherein the gutter cleaner is self-aligning on the gutter.

2. The gutter cleaner of claim 1 , wherein the at least one wheel comprises two wheels including an inner wheel and an outer wheel, and wherein the fan assembly is disposed between the inner wheel and the outer wheel.

3. The gutter cleaner of claim 2 , wherein the cage extends circumferentially around the fan assembly and is disposed between the inner wheel and the outer wheel.

4. The gutter cleaner of claim 2 , wherein the inner wheel and the outer wheel each lie along a best fit plane, and wherein the best fit planes of the inner wheel and outer wheel intersect one another.

5. The gutter cleaner of claim 1 , wherein the fan assembly comprises the fan enclosed in a volume defined at least in part by the cage.

6. The gutter cleaner of claim 1 , wherein a diameter of the at least one wheel is greater than a maximum dimension of the fan assembly.

7. The gutter cleaner of claim 1 , wherein at least one of the at least one wheels comprises a flange configured to interact with the gutter and guide the gutter cleaner along the gutter.

8. The gutter cleaner of claim 1 , wherein the gutter cleaner further comprises a handle configured to be engaged with the fan assembly, wherein the handle is configured such that an operator can remotely operate the fan assembly from ground level.

9. The gutter cleaner of claim 8 , wherein the fan assembly is coupled to the handle through a dynamic interface, and wherein the dynamic interface is self-adjustable in situ.

10. The gutter cleaner of claim 8 , wherein the gutter cleaner further comprises a battery or electrical plug disposed along the handle and spaced apart from the fan assembly.

11. The gutter cleaner of claim 1 , the primary opening is disposed adjacent to an exit port of the fan assembly, and wherein the opening is configured to receive a nozzle operable with a downspout of the gutter.

12. A method of cleaning a gutter with a gutter cleaner, the method comprising:
providing the gutter cleaner comprising:
a fan assembly configured to generate airflow;
a cage disposed around the fan assembly and including a plurality of openings, wherein the cage comprises a primary opening that passes the airflow generated by the fan assembly through the cage to the gutter; and
at least one wheel that rolls along the gutter and supports the gutter cleaner; positioning the gutter cleaner at an operable area relative to the gutter; and

moving the gutter cleaner along a length of the gutter.

13. The method of claim 12 , wherein the fan assembly is rotatably coupled to the at least one wheel such that the fan assembly remains oriented at a relatively fixed angular position as the at least one wheel rotates along the length of the gutter.

14. The method of claim 12 , further comprising aligning the gutter cleaner on the gutter such that a flange disposed on at least one wheel of the at least one wheels interacts with the gutter and guides the gutter cleaner along the gutter.

15. The method of claim 12 , further comprising:
standing at a vertical elevation below the gutter during a step of positioning the gutter cleaner; and
maintaining control over the gutter cleaner via a handle extending from the fan assembly of the gutter cleaner while moving the gutter cleaner along the length of the gutter.

16. A gutter cleaner comprising:
a fan configured to generate airflow to blow debris from a gutter;
a cage; and
a wheel configured to roll along the gutter and at least partially support the gutter cleaner on the gutter,
wherein the fan is enclosed within a volume defined by the cage and the wheel, wherein the cage comprises a plurality of openings, and wherein the cage comprises a primary opening that passes the airflow generated by the fan through the cage to the gutter.

17. The gutter cleaner of claim 16 , wherein the gutter cleaner further comprises a second wheel forming an inner wheel, wherein the wheel is an outer wheel, and wherein the fan is disposed between the inner and the outer wheel.

18. The gutter cleaner of claim 16 , wherein the primary opening has a circular profile.

19. The gutter cleaner of claim 16 , wherein the gutter cleaner further comprises a handle configured to be engaged with the fan, wherein the handle is configured such that an operator can remotely operate the fan from ground level.

20. The gutter cleaner of claim 16 , wherein a diameter of the wheel is greater than a maximum dimension of the fan.
