A brush (1) intended for industrial use comprises one or more bristle bunches formed by a plurality of elongated bristles, one or more cassette elements having said bristle bunches, and a cassette element holding member (3) at which said cassette elements may be removably secured. At least one of said cassette elements comprises a body, one or more recesses configured to receive said bristle bunches therein, and a securing wire configured to secure said bristle bunches in said recesses. Said at least one cassette element further comprises means configured to counteract movement of the bristles of a bristle bunch with respect to each other and/or with respect to the securing wire.

A strip brush assembly with a plurality of elongated polymer bristles forming a section and a plurality of elongated metal bristles forming another section adjacent the polymer bristles section, such that the metal bristles section is supported by the polymer bristles section. The polymer and metal bristles are bonded and encapsulated in a base formed by direct extrusion onto and around the polymer and metal bristles to secure them to the formed base. The strip brush assembly may be used on a tubular mandrel of a street sweeper.

An industrial robotic vacuum system for cleaning agricultural facility ventilation ductwork. The industrial robotic vacuum system generally includes a robotic vacuum head.

A roadway or pavement sweeper with multiple sweeping modes for the removal of debris from a swept surface may, in some embodiments, include a sweeper vehicle having a pair of side-brooms independently movable between a retracted and extended position for sweeping debris into an area therebetween and at least one material-transfer broom to sweep a portion of the debris accumulated between the side-brooms as the vehicle moves in its direction of travel. A fan-driven suction-inlet may be provided at or adjacent each side of the vehicle. The at least one material-transfer broom may rotate in a first or other direction to transfer debris for entrainment into a selected suction-inlet for transfer to a debris hopper. Other embodiments are also described.

A brush retrofit for mounting behind a snow plow blade of a snow removal vehicle is disclosed. The brush retrofit includes a base frame, a stationary brush assembly, a retrofit mount, a brush elevation actuator, and a retrofit mount. The stationary brush assembly is movably mounted to the base frame. The retrofit mount is configured to secure the base frame to a support structure of the snow removal vehicle behind the snow plow blade. The brush elevation actuator when activated, moves the stationary brush assembly relative to the base frame between a raised storage position and a lowered in-use position. The retrofit mount is configured to secure the base frame to a support structure of the snow removal vehicle behind the snow plow blade.

A cleaning machine may include: a first brush comprising a first brush shaft extending in a left-right direction and a first brush body held by the first brush shaft; a second brush comprising a second brush shaft extending in the left-right direction and a second brush body held on the second brush shaft; a brush supporting member supporting each of the first brush and the second brush such that the first brush and the second brush are rotatable; a body supporting the brush supporting member such that the brush supporting member is pivotable; and a pivot mechanism configured to pivot the brush supporting member with respect to the body. At least the first brush may move with respect to the body in an up-down direction when the brush supporting member pivots with respect to the body.

A side brush for a robotic cleaner. The side brush is rotatable about a rotation axis in a rotational direction and has a brush body and numerous linear bristles including a first bristle having a base end at the brush body and an opposite distal end. An imaginary line extends perpendicularly to the rotation axis. The first bristle extends in a bristle direction outwardly from the brush body. Seen in a top view, the bristle direction extends at a first angle to the imaginary line with the distal end pointing rearwardly in relation to the rotational direction. Seen in a side view, the bristle direction extends at a second acute angle to the rotation axis pointing away from the brush body. A robotic cleaner having such a side brush is also disclosed herein.

A gutter broom is provided. The gutter broom can include a mandrel, one or more carriers, each carrier removably coupled to the mandrel, and one or more bristle strips, each bristle strip removably coupled to one of the carriers. The gutter broom components can be recyclable and modular, requiring no tools for assembly or servicing.

A gutter broom is provided. The gutter broom can include one or more block segments, each block segment having openings in which bristles are positioned. The bristles can have a first stiffness or a second stiffness different than the first stiffness. Bristles having the second stiffness can be positioned radially outward of bristles having the first stiffness on a block segment.

A broom attachment is provided for a rotary sweeper assembly that includes a broom mount and a broom unit mountable to the broom mount. 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.
