The invention relates to a safety method for an emergency vehicle, the emergency vehicle being configured to be autonomously operated and comprising: an energy storage unit; sensor devices arranged to monitor the surroundings and the vehicle; a water pump; at least one connection unit for an external water source and/or a water hose; conduits arranged in fluid communication with the water pump and/or the at least one connection unit; a valve arrangement arranged in fluid communication with the water pump, the at least one connection unit and the conduits, the method comprising: receiving a command from a control center to operate the vehicle to a location associated with an emergency situation; operating the vehicle to the location; and controlling the vehicle to perform a safety function to alleviate the emergency situation.

Embodiments are directed to a street sweeper. The street sweeper may include a hopper, a pickup head, and a magnet bar. The pickup head may have an intake portion that is fluidly coupled to the hopper. The magnet bar may be disposed rearward of the intake portion of the pickup head.

The invention relates to a vacuum installation for industrial application, the installation comprising a first vessel having a first gas inlet for allowing a gaseous substance into the first vessel and a first outlet for depletion of a material, a second vessel having a second inlet for aspirating a quantity of material and a second gas outlet for depletion of the gaseous substance, wherein the gaseous substance comprises a vapour generated from the material, a storage chamber for storing the quantity of material, the storage chamber having a third inlet, wherein at least the first vessel communicates with an interior of the storage chamber via the first outlet and the third inlet; and a vacuum pump located in between the first vessel and the second vessel, and operated to lower the pressure in the second vessel, thereby allowing the material to be sucked into the second vessel via the second liquid inlet to an equilibrium level between the material and the gaseous substance, the vacuum pump being further operated to transport the gaseous substance to the first vessel to raise the pressure in the first vessel, thereby forcing the material in the first vessel into the storage chamber.

An apparatus for sweeping a ground surface, comprises: a panel member configured to be moved across a ground surface to sweep the ground surface, the panel member having an underside that, in use, faces the ground surface to be swept, an upper side that provides a collection surface for collecting debris swept from the ground surface, and one or more openings that extend between the underside and the upper side for conveying debris from the ground surface to the collection surface on the upper side of the panel member; and a debris retaining assembly configured to be mounted on the panel member for trapping the debris conveyed to the collection surface on the upper side of the panel member. The debris retaining assembly comprises a frame and a flexible cover supported spaced above the collection surface by the frame when the assembly is mounted on the panel member.

Surface cleaning device for cleaning an floor surface comprising an inner space forming casing and a liquid dispenser positioned in the inner space. The liquid dispenser 3 comprises a motor driven rotor shaft which defines an axis of rotation. Rotor arms extend radially away from a rotor shaft. Each rotor arm comprises a blade to thrust a volume of liquid medium away from the inner space in a driving direction towards a casing outlet. The liquid dispenser comprises at least one nozzle for jetting a stream of liquid onto the floor surface. The at least one nozzle has a central axis which is inclined positioned in a forward direction with respect to the driving direction under an angle of inclination with respect to the axis of rotation.

A large to medium-size sweeping and mopping vehicle and a mopping vehicle are provided. The large to medium-size sweeping and mopping vehicle includes a vehicle body, and a disc-type sweeping mechanism, a round-roller-type sweeping mechanism and a first mopping mechanism sequentially disposed along the vehicle body; the disc-type sweeping mechanism including a clean water tank and disc-type sweeping edge brushes driven by a motor and disposed obliquely with respect to ground, the clean water tank being disposed in front of the vehicle body driver zone, and a nozzle being disposed above each disc-type sweeping edge brush and in communication with the clean water tank; the round-roller-type sweeping mechanism including a refuse collector and a round-roller-type main sweeping brush driven by the motor to rotate horizontally; and the first mopping mechanism including a dragging roller, a guiding mopping roller, a guiding roller, a ring-shaped mop and a washing water tank.

A system for using a fluid to clean markings on a hard surface includes a cleaning hood operably mounted on wheels for movement across the hard surface with the cleaning hood positioned immediately above the hard surface, a set of a plurality of cleaning arms of a selected length, the cleaning arms mounted for rotation under the cleaning hood and defining a cleaning area swept by the cleaning arms, a plurality of nozzles, each nozzle mounted on one of the plurality of cleaning arms, a cleaning fluid connection carried by the hood, the cleaning fluid connection configured to fluidly connect the nozzles and cleaning arms to a cleaning fluid supply, a vacuum connection carried by the hood, the vacuum connection configured to apply vacuum from a vacuum pump to remove contaminated cleaning fluid from the hard surface to a waste fluid storage tank, and a second set of a plurality of cleaning arms of a second selected length, wherein the plurality of cleaning arms of a selected length may be replaced by the second set of cleaning arms of a second selected length, altering the cleaning area swept by the cleaning arms.
