Patent ID: 7243389

Claim:
A cleaner for a fluid environment having a surface to be cleaned, the cleaner comprising: a housing; a friction support having a first end coupled to the housing and a second free end for frictional contact with the surface to be cleaned, the friction support pivotally mounted to the housing at an angle to the surface to be cleaned, such that, upon application of a downward force, the friction support will oscillate between a first orientation and a second orientation about an axis generally lateral to the downward force; and a pair of elongated biasing members coupled between the friction support and the housing, each elongated biasing member including a first end integrally formed with the friction support and a second end coupled to the housing, the pair of elongated biasing members being located on opposite sides of the friction support with respect to the first end of the friction support, the pair of elongated biasing members acting to return the friction support from the second orientation to the first orientation upon removal of the downward force.
