A device (20) for cleaning surfaces is provided utilizing a web (94) of a tackified sheet material movably secured between rollers (56, 58) on the device (20) that enable the web (94) to be moved over the surface in opposite directions. The device (20) includes a supply roller (56) and a take-up roller (58) secured to opposed ends of the web (94) of adhesive sheet material, with at least one roller (56, 58) including a biasing mechanism (82) disposed within the roller (56, 58). The web (94) can be engaged with the surface by passing over a number of idler rollers (98) positioned between the supply roller (56) and take-up roller (58). The biasing mechanism (82) is designed to bias the movement of the web (94) onto the take-up roller (58), such that the mechanism (82) can be selectively operated to advance the web (94) from the supply roller (56) to the take-up roller (58) to expose a clean section of the adhesive sheet material (94). A synchronization mechanism (41) is also connected between the rollers (56, 58) to enable the rollers (56, 58) to rotate in a synchronous manner, regardless of the amount of the web (94) that is positioned on the rollers (56, 58) to continually tension the web (94) a proper amount. The device (20) also is designed to enable the supply roller (56) and take-up roller (58) to be removed as a unit for replacement and disposal after the entire length of the web (94) of adhesive sheet material has been utilized to clean a surface or surfaces. The rollers (56, 58) can be disposed within a housing (50, 202) having a handle (22, 205) thereon to facilitate use of the device (20). The handle (22, 205) can extend from one side of the housing (50) or can be secured to top surface of the housing (202).
