The present invention relates to a cleaning assembly and an electrical apparatus. The cleaning assembly includes: a roller configured to rotate in a first direction around an axis of rotation to clean a surface to be cleaned, the roller including a cleaning portion extending in a circumferential direction, and further including a cleaning position in contact with the surface to be cleaned and an opposite position; an arc-shaped water stopper extending from a first water stopper end to a second water stopper end in the first direction around the axis of rotation, and spaced apart from the cleaning portion; and a scraper. The scraper includes: a first scraper end connected to the arc-shaped water stopper and adjacent to the second water stopper end; a second scraper end abutting against a position of the cleaning portion downstream of the opposite position in the first direction; and a scraper body. A first distance between the first scraper end and a section of the roller at the cleaning position is not greater than a second distance between the second scraper end and the section. In this way, since the scraper body has a certain length, dirty liquid almost does not gather on the cleaning portion, which improves the cleanliness of the cleaning portion, thereby improving the cleaning efficiency.

Provided is a kitchen dispensing assembly (100) having a brewing vessel (102) and a granular material dispenser for dispensing granular material (105) into the brewing vessel. A closure member is provided for closing the brewing vessel containing the granular material. A closing system is configured to cause relative movement of the closure member and the brewing vessel so that the closure member closes the brewing vessel. A user-actuatable element (LEV) is manually moveable by a user. The closing system is configured so that, in an operational mode of the kitchen dispensing assembly, the relative movement of the closure member and the brewing vessel to close the brewing vessel is implemented automatically in a delayed closing operation that is delayed relative to the movement of the user-actuatable element, to allow the dispensing of the granular material into the brewing vessel before the brewing vessel is closed by the closure member.
