A single sweep eraser system allows cleaning of a whiteboard with a single, simple and rapid motion across the board. The system provides track brackets and glides that support a cleaning bar applying sufficient pressure to a cleaning pad extending the height of the board to provide broad area cleaning without the need for the user to lean in hard against the cleaning pad. The tracks conveniently hold the cleaning bar off to one side of the board for ready access.

An eraser assembly is provided that includes a housing, a tray, a coupler, and an eraser insert. The housing has a concave shape including an interior portion. The tray has a retaining portion disposed in the interior portion of the housing and a mounting portion disposed opposite the retaining portion. The coupler is configured to releasably hold the tray to the housing. The eraser insert is configured to be mounted to the mounting portion. An eraser insert is also provided that includes a first side and a second side, an eraser pad, and a coupler. The first side includes a mounting surface and an eraser pad is disposed on the second side. The coupler is disposed on or about the mounting surface and is configured to detachably connect the eraser insert to an eraser assembly at the mounting surface.

A whiteboard cleaning system includes a user movement sensor that determines when a user is inactive; a whiteboard capture camera that makes an image of the whiteboard when the user movement sensor detects that the user is inactive; a classification module that classifies the image with a pre-trained image data set using an augmentation technique to enhance the size of the image data set and determines whether the whiteboard needs to be cleaned based on the classification, through transfer learning, using the image data set; and a wiper that cleans the whiteboard when the classification module determines that the whiteboard needs to be cleaned.

A new design for a marker holder and eraser has a front side and a back side, the back side having a recess. The front side has two openings for retaining markers. A metal plate and a magnet holder are disposed within the recess and an erasing material covers the recess. Projections extend from the magnet holder into openings on the front side to engage markers disposed in the openings, thereby holding the markers at any angle.

A whiteboard eraser includes a first side defining a grip surface, and a second side defining an eraser surface. The eraser surface comprises a reticulated scrubbing portion. The eraser surface may also include a textile wiping portion less abrasive than the reticulated scrubbing portion.

The present invention provides tablets with interconnection features and a system of multiple tablet assemblies removably interconnected to one another. The tablets may be removably mounted to a vertical surface or positioned on a horizontal surface. Features of the present invention allow a user to remove or move one tablet from the system without disrupting or moving the other tablets.
