1. A robotic surface treating device, comprising:
- a dust bin;
a sheet of cleaning material;
means for moving the sheet of cleaning material relative to a surface to be treated; and
a housing including a compartment having an open end for separately removably receiving the dust bin and the sheet of cleaning material;
wherein the means for moving the sheet of cleaning material comprises a first roller suitable for letting out a roll of the sheet of cleaning material, a second roller suitable for reeling in the sheet of cleaning material, and a motor to cause the sheet of cleaning material to transfer between the first roller and the second roller; and
wherein the means for moving the sheet of cleaning material further comprises a sensor for monitoring the sheet cleaning material let out by the first roller and providing feedback to facilitate automatic adjustment of the rate at which the sheet is being transferred from roller to roller.

Abstract
A robotic surface treating device that can perform carpet sweeping, hard-surface dry sweeping/wiping, and hard-surface sweeping/mopping is disclosed. The robotic surface treating device includes a sweeper brush, a dust bin for collecting debris from the brush, a reel-to-reel sheet of cleaning material, and a fluid delivery system for delivering fluid from a fluid reservoir onto the sheet of cleaning material and/or onto the surface to be treated. The dust bin, reel-to-reel sheet of cleaning material, and the fluid reservoir are separately installed from the top of the device, and may be separately removed for replacement.
