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.
