The cleaning device (100) includes a motor (102), one or more shafts (104, 108) coupled to the motor (102) and el ---- coupled to one another via at least one universal joint (106), and a cleaning mechanism (110) for removing biofoul from the target ir----- surface. The cleaning device (100) includes an alignment mechanism (216) that restricts the cleaning mechanism's movement to improve Il © biofoul removal. The alignment mechanism (216) can include bearings, spring components, dampening material, adhesion components, f'1 floatation objects, or a combination thereof.
