Abstract: Cleaning devices which use cleaning sheets affixed in traps are disclosed. The traps comprise first and second jaws, each comprising base and forward portions, each forward position having a forward surface. The forward portion of the second jaw is flexible in at least a first direction, such as towards a surface over which the device is configured to move. When the second jaw is relaxed, the forward portion of the second jaw is substantially coplanar with the forward portion of the first jaw and the forward surfaces are proximate or touching. When the second jaw is flexed in the first direction (e.g., by the application of a force from a user), the forward surface of the forward portion of the second jaw moves in the first direction, away from the forward surface of the first jaw. This opens a gap through which a portion of a sheet may be inserted.

The cleaning head includes two shape-changing resilient tubes separated by an air gap opposing the vacuum airway. The cleaning head is operable in a first configuration, where the two shape-changing resilient tubes rotate against a cleaning surface engaged by the cleaning head to agitate debris on the cleaning surface to pass through the air gap and into the vacuum airway, and a second configuration, where both shape changing resilient tubes deform opposite one another to roll an object larger than the air gap to pass into the vacuum airway.

Each roller includes a resilient elastomer outer tube and a partially air-occupied inner resilient core configured to bias the outer tube to rebound. The core includes a hub and resilient spokes extending between the inner surface of the outer tube and the hub. The spokes suspend the outer tube to float about the hub and transfer torque from the hub to the outer tube while allowing the outer tube to momentarily deform or move offset from the hub during impact with debris larger than the cross sectional area between the two rollers.
