Method and apparatus for attaching a floor tool to a vacuum frame

An apparatus for attaching a plurality of floor tools to a wheeled vehicle comprising a vacuum, comprising:

• a mounting frame configured to secure to a frame of the wheeled vehicle;
• a floating frame movably attached to the mounting frame;
• a plurality of pickup tubes attached to the floating frame, said plurality of pickup tubes including a respective plurality of floor tool adapters positioned between the plurality of pickup tubes and the plurality of floor tools and configured to attach to the plurality of floor tools, wherein the plurality of pickup tubes are configured to be in fluid communication with the vacuum;
• and
• a locking mechanism to secure the floating frame to the mounting frame when the apparatus is moved to a raised position from a lowered position;
• wherein in the lowered position the floating frame and the plurality of pickup tubes are configured to float and move freely relative to the mounting frame based on undulations in a floor surface over which the plurality of floor tools travel;
• wherein the plurality of floor tool adapters include a longitudinal offset in a direction of travel of the floor tools over the floor surface and a lateral offset in an orthogonal direction to the direction of travel and wherein the plurality of pickup tubes have varying length such that the plurality of floor tool adapters include the longitudinal offset in the direction of travel of the floor tools over the floor surface.
