AUTONOMOUS FLOOR-CLEANING ROBOT
First Claim
1. A floor cleaning robot, comprising:
- a housing having an underside, a substantially semi-circular front portion, and a substantially semi-circular rear portion;
a displaceable bumper comprising a substantially semi-circular leading edge located along a front portion of the housing;
a leading wheel mounted on the underside of the housing located adjacent to a mid-point of the semi-circular leading edge;
a battery pack cover positioned rearwardly of the leading wheel and covering a battery pack that supplies power to the robot;
at least two drive wheels positioned rearwardly of the leading wheel;
at least one cleaning brush positioned rearwardly of the at least two drive wheels and configured to rotate about an axis substantially parallel to the underside;
at least one side brush having at least two arms extending outwardly from a central hub located in a recess in the underside of the housing, the at least one side brush being attached to the hub such that rotation of the hub causes the brush to direct debris from a floor surface beyond the semi-circular leading edge of the robot housing for collection by the robot; and
an ejectable dust bin having a surface forming at least a portion of a semi-circular trailing edge of the housing.

Abstract
A floor cleaning robot includes a housing having an underside, a substantially semi-circular front portion, and a substantially semi-circular rear portion. A displaceable bumper of a substantially semi-circular leading edge is located along a front portion of the housing. A leading wheel is mounted on the underside of the housing located adjacent to a mid-point of the semi-circular leading edge, and a battery pack cover is positioned rearwardly of the leading wheel and covers a battery pack that supplies power to the robot. At least two drive wheels are positioned rearwardly of the leading wheel, and at least one main brush is positioned rearwardly of the at least two drive wheels and is configured to rotate about an axis substantially parallel to the underside. The floor cleaning robot also includes at least one side brush having at least two arms extending outwardly from a central hub located in a recess in the underside of the housing, the at least one side brush being attached to the hub such that rotation of the hub causes the brush to direct debris from a floor surface beyond the semi-circular leading edge of the robot housing for collection by the robot. An ejectable dust bin is provided that has a surface forming at least a portion of a semi-circular trailing edge of the housing.

9. A floor cleaning robot, comprising:
-
a housing having a semi-circular leading edge forming a front of the housing; a bumper movable toward the housing when the bumper contacts an object; a front roller rotatably mounted on the underside of the housing and located adjacent to a mid-point of the semi-circular leading edge; a battery lid positioned rearwardly of the roller and covering a rechargeable battery that supplies power to the robot; at least two drive wheels positioned rearwardly of the roller; at least one driven brush positioned rearwardly of the at least two drive wheels and configured to rotate about an axis substantially parallel to a floor surface; at least one side brush having at least two resiliently deformable curved arms extending outwardly from a central hub located in a recess in the underside of the housing, the at least one side brush being attached to the hub such that rotation of the hub causes the brush to direct debris from the floor surface beyond the bumper for collection by the robot; and a removable dust bin having a surface forming at least a portion of a semi-circular edge forming a rear edge of the housing. - View Dependent Claims (10, 11, 12, 13, 14)

15. A floor cleaning robot, comprising:
-
a housing having an underside; a substantially semi-circular bumper having a front edge, the bumper extending around a portion of the housing; a front wheel rotatably mounted on the underside of the housing located adjacent to a mid-point of the front edge; a battery cover positioned rearwardly of the front wheel and configured to cover a rechargeable battery that supplies power to the robot; two drive wheels positioned rearwardly of the front wheel, the two drive wheels located adjacent a substantially arcuate lateral edge of the housing; at least one power brush positioned rearwardly of the two wheels and configured to rotate about an axis substantially parallel to the underside; at least one side brush having at least two curved arms extending outwardly from a central hub located in a recess in the underside of the housing, the at least one side brush being attached to the hub such that rotation of the hub causes the brush to direct debris from a floor surface beyond the front edge of the robot housing for collection by the robot; and an ejectable dust bin having a surface forming at least a portion of a semi-circular edge forming a rear side of the housing. - View Dependent Claims (16, 17, 18, 19, 20)
