Hand-guided treatment device for walkable surfaces adapted to clean, sanitize and dry such surfaces, including a guiding body joined below, through an articulated element to a unit for cleaning, sanitizing and drying such surfaces, the guiding body having housed inside it at least a control and command electronic circuit board powered by at least an electrical transformer, at least a first reservoir and at least an electrical pump. The unit has component elements assembly inserted into a stiff and shell-shaped casing, this latter being opened on its lower part and provided at its lower part with at least a free wheel, for moving the device, and being provided on its upper part with an upper opening, in correspondence of the articulated element, adapted to connect the component elements of the guiding body and component elements assembly.

A multi-use garbage truck has an ability to not only to front load containers of garbage into a hopper in a refuse collection body, but also an ability to swap out the forks, if not arm connection assemblies, or even entire frame arms, to be replaced with one of a plurality of attachments which connect to at least one, if not both frame arms with attachments for various uses such as snow plow, leaf blower, street sweeper, bucket, grapple, etc. Furthermore, an ability to independently operate the left frame arm relative to the right frame arm can now be provided so that the left frame arm can utilize and perform one function and the right frame arm provide another or at least be independently operable from one another.

A cleaner includes a body forming an external appearance, a rotating plate provided at a lower side of the body, a mop unit coupled to a lower side of the rotating plate so as to be in contact with a floor, a spin shaft connected to an upper side of the rotating plate so as to rotate the rotating plate, a water supply reservoir configured to surround a periphery of the spin shaft and spaced apart from the spin shaft so as to define a water supply space, and a water supply module configured to supply water to the water supply space. The rotating plate forms a water supply hole configured to interconnect the water supply space and the lower side of the rotating plate.

Systems and methods for detecting a site maintenance operation done by a maintenance device are described. At least one motion sensor and at least one localization sensor can each be operatively coupled to the maintenance device to detect one or more motion parameters of the maintenance device via the motion sensor and the localization sensor. The maintenance device can be localized (e.g., its position located) on the indoor map. A movement of the maintenance device can be characterized and/or tracked on the indoor map. A motion map can be displayed to illustrate (e.g., visually represent) the characterized movement. An offsite computer can be used to determine whether the site maintenance operation has commenced at the indoor location, measure one or more maintenance parameters of the site maintenance operation and/or compare the one or more maintenance parameters to predetermined benchmark parameters to determine whether the site maintenance operation has been completed.

A self-cleaning carpet system including a carpet base, a cleaning tube, a piston, a carpet fiber group, a water assembly and a vacuum assembly. The cleaning tube is mounted in the carpet base. The piston is operably mounted with respect to the cleaning tube for movement between a retracted position and an extended position. The carpet fiber group is attached to the piston. When the piston is in the retracted position, the carpet fiber group is substantially inside the cleaning tube. When the piston is in the extended position, at least a portion of the carpet fiber group extends from the cleaning tube. The water assembly is fluidly connected to the cleaning tube for delivering water to the cleaning tube. The vacuum assembly is fluidly connected to the cleaning tube for applying a vacuum to the cleaning tube.

A robot cleaner includes a rolling cleaning module including a rolling member configured to rotate clockwise or counterclockwise when viewed from a left side while in contact with a floor, a sensor unit, and a controller. The controller is configured to determine a change in position of the robot cleaner and a change in load current of a motor connected to the rolling member based on data detected by the sensor unit, and determine that a specific area of the floor is a contaminated area when there is a change in the position and a change in the load current.
