## Abstract

An apparatus, system, and method are disclosed for self-cleaning dust removal. The apparatus may be provided with a brush housing 202 having an opening 204, one or more axles 206 disposed around the opening 204, and a plurality of brush fibers 208 emanating from the one or more axles 206 that rotate inward into the opening 204. In addition, the system may include a scraping edge 106, disposed around the opening 204, farther into the brush housing 202 than the one or more axles 206, that scrapes 1408 dust off of the brush fibers 208 as they rotate inward against the scraping edge 106, and a vacuum cleaner intake port 110 inside the brush housing 202 that draws 1410 dust from off and about the brush fibers 208 as they rotate inward 1406. The system may further include a handle 112 connected to the brush housing 202 and a switch 114.

## Claims

### Claim 1

An apparatus comprising:
a brush housing having an opening, wherein the opening has a substantially circular shape;
one or more axles disposed around a perimeter of the opening in the brush housing, wherein the one or more axles are flexible and conform to the circular shape of the opening in one or more arcs; and
a plurality of brush fibers emanating from the one or more axles that rotate inward toward opposing brush fibers that rotate inward in an opposite direction about the one or more axles into the opening.

### Claim 2 (depends on 1)

The apparatus of claim 1, further comprising a scraping edge, disposed around the opening, farther into the brush housing than the one or more axles, that scrapes dust off of the brush fibers as they rotate inward against the scraping edge.

### Claim 3 (depends on 1)

The apparatus of claim 1, further comprising a vacuum cleaner intake port inside the brush housing that draws dust from off and about the brush fibers as they rotate inward.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the one or more axles comprise two substantially semicircular axles.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein the one or more axles comprise a single substantially circular axle.

### Claim 6 (depends on 1)

The apparatus of claim 1, wherein the brush fibers are selected from the set consisting of microfibers, electrostatic fibers, polyester fibers, wool fibers, and feathers.
