  • Patent number: 9248974
    Abstract: Devices for removing particulate from surfaces may include at least one belt coupled with at least one guide to rotate the belt(s) about the guide(s). A vacuum cavity may be disposed around a portion of the belt(s) to remove captured particulate therefrom when a negative pressure is introduced in the vacuum cavity. A surface may be cleaned by rotating a dry belt about a guide and positioning a portion of the dry belt on the surface to capture and collect particulate. A portion of the dry belt can pass into a vacuum cavity, and collected particulate may be removed from the dry belt into the vacuum cavity. A cleaning apparatus may be formed by coupling a belt to a guide so the belt can rotate around the guide. A vacuum cavity can be disposed to encompass a portion of the belt. Other aspects, embodiments, and features are also included.
