The Garage Air-N-Vac Station is an integrated wall-mounted vacuum, blower, and air compressor. The integrated system includes provisions for wall-mounting, tool and accessory storage, a wand hanger, and hose hangers for the combined vacuum/blower hose as well as the compressed air hose. The vacuum and blower sections of the machine are powered by a combination vacuum/blower motor, with the vacuum function utilizing the intake side of the vacuum/blower motor, and the blower function utilizing the discharge side of the vacuum/blower motor. A tankless compressor provides compressed air at full capacity. The machine is operated by a single 3-way control switch (On-Off-On) to activate either the vacuum/blower function or the compressor function. The elements that make this invention new and novel relate to its multi-function capabilities, combined with the integrated wall-mounting, tool, and hose storage system that has been optimized for ease of installation, convenience of use, organization, and appearance.

A dust collecting device with an extendible and flexible air tube including a housing, a cover, an air tube, a dust collecting head, a filter material and a gas guiding device. The cover is detachably disposed on the housing and has an accommodating groove. The air tube is positioned in the accommodating groove and extendible and flexible, the air tube is capable of being extended to outside the accommodating groove and retracted to be accommodated in the accommodating groove, and a bending angle and an extension direction of the air tube is changeable by flexibility. The dust collecting head is disposed at the air tube, and is positioned in the accommodating groove when the air tube is shortened to be accommodated in the accommodating groove. The filter material is disposed inside the housing and close to the cover. The gas guiding device is disposed inside the housing.

A vacuum tool configured to be removably coupled to hose or wand of a vacuum includes a body including a first end, a second end, and a first longitudinal axis extending between the first end and the second end. The vacuum tool also includes a head coupled to the first end of the body, a connection portion coupled to the second end of the body and configured to couple the body to a hose or wand of a vacuum cleaner, and a brush coupled to the head. The brush includes an elongate support defining a second axis perpendicular to the longitudinal axis of the body and configured to couple the brush to the head, and a plurality of bristles positioned on the elongate support.

A hand vacuum cleaner has a dual first stage cyclones.

An environmental control unit comprises a housing, a vacuum cleaner, a filtration unit, and a blower. The vacuum cleaner is positioned in the housing and is configured to receive a tool contaminant stream produced by at least one tool. The vacuum cleaner filters particulate matter from the tool contaminant stream, thereby producing a filtered air stream. The filtration unit is also positioned within the housing and comprises at least one filter. The blower is positioned within the housing downstream of the filtration unit. The blower is configured to create negative air pressure within the second compartment to draw an area contaminant stream from an exterior of the environmental control unit into the housing. A second blower may also be present. The blower draws the filtered air stream and the area contaminant stream through the at least one filter in the filtration unit to produce a filtered mixture stream.

The present disclosure provides a surface cleaning apparatus that includes a recovery system that extracts liquid and debris with a drying cycle in which forced air flows through a recovery pathway of the recovery system to dry out components that remain wet and/or retain moisture after normal operation of the apparatus. The post-operation drying cycle can dry out components such as an agitator or brushroll, a brush chamber, a suction nozzle, a recovery tank, a filter, and any of the various conduits, ducts, and/or hoses fluidly coupling components of the recovery system together.

The present disclosure relates to a plurality of autonomous mobile robots. A plurality of autonomous mobile robots comprise a first mobile robot including an antenna configured to transmit and receive signals, and a second mobile robot including a first antenna and a second antenna disposed on a front area of a main body thereof to transmit and receive signals to and from the antenna of the first mobile robot. The second mobile robot comprises a control unit configured to determine a relative position of the first mobile robot using the signal received by the first antenna and the second antenna.

An operation management system includes an automatic traveling vehicle and a management server. The vehicle includes a first processor, and is configured to transport at least one of people or luggage. The management server includes a second processor, and is configured to communicate with the vehicle and manage the operation thereof. The first processor or second processor is configured to: determine whether there is a transport task in which the vehicle transports at least one of people or luggage; and, when there is no transport task, execute a task switching process of causing the vehicle to execute any one of a patrol task in which the vehicle performs a patrol of an operating area of the vehicle, a cleaning task in which the vehicle performs a cleaning of the operating area, and a patrol cleaning task in which the vehicle performs both the patrol and the cleaning.

The present disclosure relates to a plurality of autonomous mobile robots. A plurality of autonomous mobile robots comprise a first mobile robot including an antenna configured to transmit and receive signals, and a second mobile robot including a first antenna and a second antenna disposed on a front area of a main body thereof to transmit and receive signals to and from the antenna of the first mobile robot. The second mobile robot comprises a control unit configured to determine a relative position of the first mobile robot using the signal received by the first antenna and the second antenna.

A system for environmental maintenance includes a vacuum unit, an air purifier unit, a controller communicatively connected to the vacuum unit and the air purifier unit, a sweep sensor communicatively connected to the controller, and a movement sensor communicatively connected to the controller. The sweep sensor detects debris and sweeper swept into a detectable vicinity of the sweep sensor and the controller turns on the vacuum unit upon detection by the sweep sensor. The controller turns on the air purifier unit upon the vacuum unit being turned on, and the air purifier unit cycles on for a period as programmed in the controller. The movement sensor detects movement in detectable vicinity of the movement sensor and the controller turns on the air purifier unit upon detection by the sweep sensor, if the air purifier is not already turned on.
