Abstract
A forward articulating cleaning and removal apparatus for cleaning a drainage structure. An example apparatus includes a housing to extend into a structure to be cleared and/or removed, through an open end of the structure to be cleared. The example apparatus also includes a distal edge formed on the housing to cut or loosen debris. At least one coil within the housing moves the cut or loosened debris away from the distal edge formed on the housing to a proximal end of the housing. A debris escape opening is formed in the proximal end of the housing. A stem at the proximal end of the housing is provided for connecting to a rotational power source to drive the housing. The example apparatus includes at least one cutting edge on the distal edge of the housing and/or the at least one coil within the housing.
