A cleaning device includes a chassis that can be moved over a ground surface. The cleaning device further includes a space in which a roller-shaped brush provided with bristles is arranged in a rotatable manner about an axle in such a way that the ground can be brushed therewith. The space is connected to an outlet channel for the removal of material brushed away by the bristles. An air channel is arranged in the brush and coaxially with the axle. The air channel has a series of openings directed towards the outlet channel and open between the bristles.

A coupling for a tube includes an attachment and a housing. The attachment is attached to the tube and has a barrel-shaped exterior surface. The housing contains the barrel-shaped exterior surface such that the attachment is rotatable in the housing while not being removable from the housing. The coupling thereby allows easy rotation of the tube within the coupling. The coupling may be utilized to attach the tube to another tube or to another structure.

A collection device for debris and animal waste is an apparatus that optimizes airflow to effectively and safely collect debris, preferably pet waste. The apparatus includes a canister, at least one handle assembly, an airflow inlet nozzle, a portable power source, and a fan assembly. The canister houses collected debris and the fan assembly. The at least one handle assembly, the airflow inlet nozzle, and the portable power source are mounted with the canister. The at least one handle assembly allows a user to easily maneuver the canister and the airflow inlet nozzle. The fan assembly suctions debris into a debris chamber of the canister through the airflow inlet nozzle. The portable power source provides the necessary power for the fan assembly to operate. The apparatus further includes an air-permeable collection bag that is housed within the debris chamber to facilitate the removal of collected pet waste within the canister.

A backpack blower working machine includes: a back frame worn to be carried on a back of a worker; a volute case mounted on the back frame; a centrifugal fan equipped in the volute case; an electric motor assembled to the volute case and configured to rotate the centrifugal fan; and a battery attached to the back frame and configured to supply the electric motor with electricity. The back frame includes an upper section and a lower section. Shoulder belts for carrying and the volute case are provided on the upper section. A battery arrangement space for the battery is provided in the lower section, and has a length in an up-and-down direction and a length in a right and left direction each of which is longer than a length in a front-to-back direction.

A cleaning system for pavement joints controlled and driven by a motor. A wheeled housing carries a nozzle system where a stream of pressurized or forced air is directed through rotating nozzles to clean the joint surfaces. The rotational speed (RPM) of the motor is selectively controlled by actuation of a valve by the operator, and allows the operator to selectively control the rate of rotation of the nozzles are required by the state of the surface to be cleaned. A suction head is further movable over the joint surfaces to remove the debris dislodged by the nozzle system and airflow.

The present invention relates to a garden blower. The garden blower includes: an extension rod; an air duct portion, disposed on one end of the extension rod; a motor; a fan; and an operating handle, spaced apart from the air duct portion in a longitudinal direction, where a ratio of a length of the air duct portion in the longitudinal direction to a length of the entire garden blower in the longitudinal direction is less than or equal to 60%, and a weight of the garden blower does not exceed 2 kg.

Outdoor power equipment includes a chassis, a blower housing, a discharge housing, and a deflector assembly. The blower housing is supported by the chassis. The discharge housing is coupled to the blower housing and is defined by a first discharge chute and a second discharge chute that extend in opposite directions. An impeller is received within the blower housing and is configured to rotate within the blower housing to direct air from the blower housing toward the discharge housing. The deflector assembly is supported by the chassis and includes an actuator and a deflector. The deflector is movable within the discharge housing in response to movement by the actuator to selectively direct flow from the blower housing through the first and second discharge chutes.

A blower appliance includes: a carrying harness, at least one blower fastener, a blower having an air outlet, and a nozzle, connected downstream of the air outlet by way of an elastic bellows having a return effect. The blower fastener having an articulation having a return effect, which tends to return the axis of the air outlet of the fan body towards a rest position, the articulation having a return component, parallel to the spinal axis, with a second spinal return stiffness, the second spinal return stiffness being greater than the first spinal return stiffness of the elastic bellows. The blower appliance finds applications in the maintenance of parks and gardens.

One or more autonomous street sweeper vehicles can perform a variety of sweeping functions, such as sweeping, vacuuming, blowing, and scraping. Each autonomous street sweeper vehicle can be designed to follow routes and can comprise an autonomous vehicle that includes a drive by wire kit, a database storing the routes, a detection mechanism, and a control system that controls the vehicle to follow the routes while maintaining serviceable distances to the curb. In a convoy of multiple autonomous street sweeper vehicles, the vehicles in the convoy can communicate with each other, and each of the autonomous street sweeper vehicles can perform a different function. In some examples, a speed of the vehicle and/or settings of the cleaning equipment can be adjusted, for example, based on road hazards or amount of debris.
