Abstract: A cleaning system and a method for cleaning a surface of a ferromagnetic object are disclosed. Accordingly, to an example configuration, the cleaning system includes a device body that comprises a magnetic system that urges an abrasive layer against the surface of the ferromagnetic object by a magnetic force. In at least some examples, the magnetic force provided by the magnetic system is adjustable to achieve a target magnetic force for cleaning the surface.

Abstract: A cleaning system and a method for cleaning a surface of a ferromagnetic object are disclosed. Accordingly, to an example configuration, the cleaning system includes a device body having a guide face configured for selective placement against the surface. The device body comprises a magnetic system generating a magnetic field configured to urge the guide face against the surface of the ferromagnetic object by a magnetic force. The cleaning system further includes a scraper blade projecting outward from the device body to contact the surface upon placement of the guide face against the surface. The guide face may optionally comprise an outward-facing abrasive surface.

Abstract: An apparatus and related method for mixing and/or applying a cementitious product. The apparatus includes a container for holding a cementitious product, a pump for delivering the cementitious product from the container to an applicator head, and an applicator head for shaping and applying the cementitious product to a surface so as to have a desired thickness and contour.
