Abstract: A robotic cleaner includes a housing, a suction conduit with an opening, and a leading roller mounted in front of a brush roll. An inter-roller air passageway may be defined between the leading roller and the brush roll wherein the lower portion of the leading roller is exposed to a flow path to the suction conduit and an upper portion of the leading roller is outside of the flow path. Optionally, a combing unit includes a plurality of combing protrusions extending into the leading roller and having leading edges not aligned with a center of the leading roller. Optionally, a sealing strip is located along a rear side of the opening and along a portion of left and right sides of the opening. The underside may define side edge vacuum passageways extending from the sides of the housing partially between the leading roller and the sealing strip towards the opening.

Abstract: Disclosed are embodiments of document scanner, a method and a program storage device wherein the scan mode is automatically adjusted to fall within standards established to prevent vision damage and/or discomfort and to still allow for high-resolution scanning. Specifically, the platen cover of the document scanner can be operatively connected to the scan carriage such that the mode at which the scan carriage operates depends upon the detected position of the platen cover. When the platen cover is closed, the scan carriage can automatically illuminate the document being scanned at a relatively high light intensity level and can move at a relatively fast speed. When the platen cover is opened, the scan carriage can automatically illuminate the document being scanned at a lower light intensity level and, optionally, can move at a slower speed to compensate for the lower light intensity level.
