Oscillating mechanisms with side brushes are presented including: a base assembly, the base assembly including, a base plate, a rotating axle extending perpendicularly from the base plate, at least one arm coupled with the rotating axle, a slot along a path of the at least one arm, and a first anchor positioned along a proximal end of the slot; and a brush assembly slidingly coupled with the base assembly, the brush assembly including, a hub slidingly coupled with the base plate along the slot, a side brush coupled with the hub, the side brush extending outwardly from the base assembly, a second anchor positioned along the hub, and a return spring coupled with the first anchor and the second anchor. In some embodiments, mechanisms further include: at least two arms coupled with the rotating axle, the at least two arms positioned at least 90 degrees apart from each other.

A first work tool arm is rotatably attached to a frame or reference structure, a second work tool arm rotatably attached to the first work tool arm, and a work tool attached to an end of the second work tool arm. An actuator and a spring are each rotatably attached to the second work tool arm and configured such that separate movement of the first work tool arm relative to the frame or reference structure and movement of the second work tool arm and work tool relative to the first work tool arm are achieved with actuation of the actuator.

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.

The invention concerns a dish brush (1, 11) for conventional sweeping machines for cleaning, brushing or sweeping paved surfaces, wherein special constructed sweeping elements (4) and steel cable plugs (5) both waste and weeds remove from different types of paved surfaces. The mentioned sweeping elements (4) are fastened with welds (8,9) from the top side of the raised contour edge (2) through slit openings (6,7) and the steel cable plugs (5) are fastened with a weld (10) from the bottom side of said contour edge (2). The advantage is a well applicable sweeping and weeds removing dish brush (1,11) and which can be manufactured in a very economical way.

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

A deck-slab waterproofing-membrane application brush for coating highway-bridge deck slabs with a waterproofing membrane, and a deck-slab waterproofing-membrane application apparatus for towing the brush to spread on waterproofing product are made available to enable the applying of deck-slab waterproofing membranes uniformly, safely, and efficiently to highway bridges. The deck-slab waterproofing-membrane application brush, for spreading on highway-bridge deck-slab waterproofing product, is characterized in that inside a furrow in a furrowed metal plate, numerous metallic bristles are aligned into rows in a packed, sheet-like form and fastened in a state in which the numerous metallic bristles are clamped.

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 floor cleaning machine that includes a disc broom that is rotatable about a rotation axis. The disc broom has a base body, bristles and a cover element. The base body has a circumferential outer edge. The bristles are attached at one end to the base body and extend away from the base body towards a sweeping plane that is perpendicular to the rotation axis. The cover element has a shell that is made of a flexible material. The shell extends away from the base body and towards the sweeping plane. The shell has an inner side, which faces an interior of the shell, and an outer side that faces an exterior of the shell. The shell envelopes the bristles perpendicularly to the rotation axis such that the bristles are disposed in the interior of the shell. A related disc broom and sweeping device are also provided.

A cleaning device including a covering hood having a lower surface facing a surface to be cleaned and an inlet on an upper surface thereof, through which contaminants are sucked; an air knife provided on a circumference of the covering hood and having an outlet for spraying high pressure air to the surface to be cleaned; a sweeper installed inside the covering hood and rotated by a driving motor to guide foreign objects swept away from the surface to be cleaned and contaminants floated by the high pressure air injection of the air knife to the inlet; a rotary member including a shaft passing through a circumferential surface of the covering hood and the air knife, and a rotary knob coupled to one end of the shaft to rotate the air knife to adjust an air spray angle.
