The broom attachment includes a plurality of broom attachment bristles and a support member having a retained portion and a retaining portion. The plurality of bristles extend from the retaining portion and the retained portion is operatively mountable to at least one of the broom mount and the broom unit. A broom assembly includes at least one broom attachment. When the broom attachment is operatively mounted to the broom mount, the broom attachment bristles are positioned at a greater radial distance away from an axis of rotation than the cleaning bristles of the broom unit. A method of assembling a broom attachment to a broom mount includes operatively mounting the retained portion to the broom mount. ## Claims ### Claim 1 A broom assembly, comprising: a rotary sweeper assembly including a circular broom mount having a surface and at least one broom section mounted to the broom mount, each of the at least one broom section including a segment holding cleaning bristles; a broom attachment, comprising: a plurality of gutter bristles; and a support member having a retained portion and a retaining portion, the plurality of gutter bristles extending from the retaining portion; the retained portion being operatively mounted to the surface the broom mount, such that the gutter bristles of the broom attachment extend outwardly relative to the cleaning bristles of the at least one broom section, the broom mount having an axis of rotation that extends substantial perpendicular to the surface of the broom mount; wherein the gutter bristles are positioned at a greater radial distance away from the axis of rotation of the broom mount than the cleaning bristles of the at least one broom section; and a broom fastener projecting through the broom mount, the retained portion and the at least one broom section, thereby securing the broom attachment to the broom mount and the at least one broom section. ### Claim 2 (depends on 1) The broom assembly according to claim 1, wherein a distance of the gutter bristles of the broom attachment away from the axis of rotation of the broom mount is adjustable. ### Claim 3 (depends on 1) The broom assembly according to claim 1, wherein the gutter bristles are arranged in at least one row and wherein the at least one row is spaced away from a last row of cleaning bristles of the at least one broom segment. ### Claim 4 (depends on 1) The broom assembly according to claim 1, wherein the broom attachment is one of a plurality of broom attachments operatively mounted to the broom mount, the plurality of broom attachments being spaced angularly apart about the axis of rotation of the broom mount. ### Claim 5 (depends on 1) The broom assembly according to claim 1, wherein the broom fastener includes a bolt. ### Claim 6 (depends on 1) The broom assembly according to claim 1, wherein the broom attachment is pinched between the broom mount and the broom section. ### Claim 7 (depends on 1) The broom assembly according to claim 1, wherein the surface is a bottom surface of the broom mount. ### Claim 8 (depends on 7) The broom assembly according to claim 7, wherein the retained portion is pinched between the broom mount and the at least one broom section. ### Claim 9 (depends on 1) The broom assembly of claim 1, wherein the retained portion is directly mounted to at least one of the broom mount and the at least one broom section. ### Claim 10 (depends on 1) The broom assembly of claim 1, wherein the retained portion of the support member has a broom mount surface for facing the broom mount, the broom mount surface being mounted to the broom mount. ### Claim 11 (depends on 1) The broom assembly of claim 1, wherein the retained portion of the support member has a broom section surface facing the at least one broom section, the broom section surface being mounted to the at least one broom section. ### Claim 12 (depends on 1) The broom assembly of claim 1, wherein the retained portion of the support member comprises a metallic plate. ### Claim 13 (depends on 1) The broom assembly of claim 1, wherein the retained portion of the support member has a slot formed therein that receives a broom fastener. ### Claim 14 (depends on 13) The broom assembly of claim 13, wherein the slot is elongated and extends radially relative to the at least one broom section. ### Claim 15 (depends on 1) The broom assembly of claim 1, wherein the retained portion comprises a tooth for gripping the at least one broom section. ### Claim 16 (depends on 1) The broom assembly of claim 1, wherein the retaining portion comprises an opening that receives upper extremities of the gutter bristles. ### Claim 17 (depends on 16) The broom assembly of claim 16, wherein the retaining portion comprises opposed sidewalls, the gutter bristles being secured to the retaining portion by pressing the upper extremities between the opposed sidewalls. ### Claim 18 (depends on 1) The broom assembly of claim 1, wherein the gutter bristles are arranged in at least one row. ### Claim 19 (depends on 1) The broom assembly of claim 1, wherein the gutter bristles comprise compressed steel cables. ### Claim 20 (depends on 19) The broom assembly according to claim 19, wherein the gutter bristles have a diameter of about 3/16 of an inch to about ½ of an inch. ### Claim 21 (depends on 20) The broom assembly of claim 20, wherein the broom attachment weighs less than about 2.5 lbs. ### Claim 22 (depends on 1) The broom assembly according to claim 1, wherein the broom mount comprises a cylindrical drive plate. ### Claim 23 (depends on 22) The broom assembly according to claim 22, wherein the at least one broom section comprises an annular member.
