Abstract

In embodiments of the present invention, a gutter-cleaning device comprises a housing containing an impeller drive facility, the housing configured to fit into a gutter, an impeller, disposed at an end of the housing and driven by the impeller drive facility, and a transport facility for transporting the housing along the gutter.

Claims

1. A gutter-cleaning device, comprising:

a housing containing an impeller drive facility including a motor rotationally operable at more than 400 rpm, the housing having a height of not more than 2.75 inches and the housing configured to fit into an open residential gutter;

an impeller having an axis disposed at an end of the housing and connected to an output of the impeller drive facility, the impeller having a plurality of impeller vanes coupled to the axis including at least one flexible paddle and at least one stiff bristle brush, each one of the plurality of impeller vanes sufficiently flexible to facilitate deflection under a cross brace of the open residential gutter, wherein the axis is oriented parallel to a direction of travel of the device when placed for use in the open residential gutter;

a transport drive including tractor/tread wheels and tracks adapted to transport the device along an interior surface of the open residential gutter;

a wireless communication facility mounted within the housing and operable to receive control signals from a remote control for controlling at least one of the transport drive and the impeller drive facility;

an antenna electrically connected to the wireless communication facility and disposed flush against the housing;

at least one nickel cadmium battery within the housing to provide power to at least one of the impeller drive facility, the transport drive, and the wireless communication facility; and

a placement facility with a removable and replaceable attachment point to assist a user in placement of the gutter-cleaning device in the open residential gutter.

2. The device of claim 1, wherein the placement facility facilitates placement of the gutter-cleaning device into the gutter.

3. The device of claim 1, wherein the impeller is formed from at least one of a molded elastomer, neoprene, rubber, plastic, and an electrostatic cloth.

4. The device of claim 1, wherein the impeller further includes at least one of a helical bristled brush, a full stiff bristle brush, a spiral stiff bristle brush, a wire brush, a dethatching brush, an alternating paddle brush, a flexible bucket, a multiply vaned impeller, and an alternating flexible blade.

5. The device of claim 1, wherein the transport drive drives at least one of a wheel, a snake drive, a worm drive, a crab or walking drive, a scoot-and-compress or accordion drive, and a string of beads drive.

6. The device of claim 1, further comprising a vision system disposed on the housing for facilitating navigation and programming of the device.

7. The device of claim 1, further comprising a navigation system to facilitate autonomous control of the device.

8. The device of claim 7, further comprising a programming facility to set programs for autonomous control of the device.

9. The device of claim 1, further comprising a remote control facility for communicating with the wireless communication facility to remotely control at least one of the transport drive and the impeller drive facility.

10. The device of claim 9, wherein an antenna of the remote control facility is associated with a placement facility.

11. The device of claim 1, wherein the housing has a height less than one or more gutter cross braces of the open residential gutter.

12. The device of claim 11 further comprising an impeller chute to direct debris from the impeller, the impeller chute configured to be lower in height than the gutter cross braces.
