A vessel cleaning robotic system includes a robotic cleaner having a cylindrical central unit from which three retractable legs extend. Each leg includes an omni-directional wheel at its distal end, a motor, up to three joints for articulation, and a collar for attachment to the central unit at a proximal end. An arm, also extending from the central unit, is configured to rotate around it, with a cleaning sub-unit at its distal end and a collar at its proximal end. The arm includes a vacuum pipe and a spraying device for cleaning purposes. Integrated within the retractable legs and the arm is a monitoring unit comprising sensors for operational monitoring.

A method for cleaning an ice-making device includes obtaining a cleaning start instruction, and in response to the cleaning start instruction, injecting cleaning liquid into an ice-making cylinder of the ice-making device through a water inlet on the ice-making cylinder, and driving an ice-scraping screw in the ice-making cylinder to rotate to clean the ice-making device.

Extraction devices and mechanisms for removing debris from a beverage capsule are described, in addition to beverage devices including such an extraction device. Methods of cleaning and reusing a beverage capsule are also described.

An herb grinder with a cleaning attachment comprises a bristle assembly and a grinding assembly which is further comprised of a top grinding component, a bottom grinding component and a collecting compartment. The top grinding component and the bottom grinding component are detachably connected and are configured to be rotated relatively to each other. The bristle assembly and the grinding assembly form an internal space configured to receive the bristle plate, and are both interlocking and magnetically connected to prevent relative rotation between the bristle assembly and the grinding assembly when grinding. The bristle assembly may be detachable to clean the top grinding component and the bottom grinding component. The herb grinder further comprises a housing which is interchangeable with the grinding assembly for convenient portability and storage.

A smoking article includes identification information encoded on the smoking article. The smoking article can be used with an electrically heated smoking system having a detector for detecting the smoking article and distinguishing the smoking article from other articles based on the identification information. A cleaning article includes identification information encoded on the cleaning article. The cleaning article cleans an electrically heated smoking system having a detector for detecting the cleaning article and distinguishing the cleaning article from other articles based on the identification information. An electrically heated smoking system for receiving an article configured for use with the smoking system includes: a cavity for receiving the article having identification information encoded thereon, a heating element, a power supply, electrical hardware, and a detector capable of detecting the presence of the article in the cavity and distinguishing the article from other articles based on the identification information.
