Retrofit box systems to maximize operational capacity of inaccessible floors are described. The retrofit box system includes a gate complex that provides fluid communication between an inaccessible floor and a box, and a box to deliver a cleaner to the inaccessible floor and adapted for equalizing pressure when the inaccessible floor is under water while minimizing waste seepage from the retrofit box system. The retrofit box system further includes a power system and a control system to deliver the cleaner to the inaccessible floor and remove waste from the inaccessible floor and the box.

A bag washer for plastic storage bags is provided. The bag washer comprises a vertical component and a base component. The vertical component comprises a plurality of intersecting structs to form gaps. The vertical component is configured in size and shape to fit within a space between a first layer and a second layer of the plastic storage bag. The base component comprises a generally horizontal surface from which the vertical component extends.

An apparatus for cleaning a bowl includes a base plate, and a blade coupled to the base plate. The blade extends in a curve on a surface of the base plate in a direction receding from a center of the base plate in a plan view. An inner side surface of the blade includes a curved surface concavely recessed toward an inside of the blade in a cross-sectional view taken along a direction perpendicular to an extending direction of the blade.

A cleaning device for a mixing vessel of a food processor operated by an electric motor, wherein the mixing vessel has a vessel bottom, a circumferential wall and a cover element and can be connected to a rotary element in a torque-proof manner with the aid of a fasteners and is designed for sweeping over at least a partial area of an inner wall of the mixing vessel and mechanically removing deposits located thereon during a rotation of the rotary element about a rotational axis. The cleaning device is in the form of a bristle element or wiper element and has a C-shaped design that is in contact with the vessel bottom, the circumferential wall and the cover element such that cleaning of the vessel bottom, the circumferential wall and the cover element can take place simultaneously when the mixing vessel is closed with the cover element.

A tool for cleaning inside of a water tank utilizing a siphon action is provided in which a scraping tool (S) is pivotably provided at an upstream end of a suction pipe (P), a deposit (b) such as moss caked on a bottom face or a side face within the water tank is scraped off by a scraping blade (62) formed at an extremity of the scraping tool (S), and is removed by sucking up together with dirt (a).
