Abstract

An elongated hand held scrubbing device has a pair of motor-driven rotary hubs, onto which a variety of easily replaceable cleaning heads can be temporarily mounted. Different types and styles of cleaning heads can be used based on the type of scrubbing, buffing, wiping or cleaning required. The elongated device has a pivot making it easier to scrub hard to reach locations.

Dependent claims

A motorized scrubber comprising:

a first elongated body portion having opposed first and second ends defining a handle for said scrubber, said handle having a first longitudinal axis passing through said first and second ends defining said handle,
a second elongated body portion having opposed first and second ends defining a head and neck for said scrubber, said head and neck having a second longitudinal axis passing through said first and second ends defining said head and neck,
means for pivotally connecting said head and neck to said handle such that said head and neck is movably adjustable relative to said handle through a range of positions where said first axis is co-linear with said second axis in a first position and where said first axis makes an angle with respect to said second axis in a second position,
a cleaning member;
axle means for supporting said cleaning member for rotation about an axis extending orthogonally with respect to at least said second axis, means on said head and neck proximal to said first opposed end of said elongated body portion for mounting said axle means for rotation thereon,
motor means for rotating said axle means to cause said cleaning member to rotate about said orthogonal axis, said first elongated body portion having a first hollow interior space, said motor means being mounted in said first hollow interior space and having an output shaft,
transmission means for connecting said motor means output shaft to said axle means,
said second elongated body portion having a second hollow interior space, and
said transmission means extending through said second hollow interior space and being movably adjustable through said range of motions of said head and neck relative to said handle,
wherein said cleaning member comprises a hub adapted to mounted on said axle means, said hub having a removable head mounted thereto, said removable head comprising a hemispherically shaped hollow housing for defining an enclosed reservoir adapted to contain a liquid cleaning substance, said housing comprising a porous wall for allowing said substance to flow from said reservoir to the exterior of said housing during rotation of said cleaning member on said axle means.

a first cleaning member having a work engaging face, said first cleaning member being removably coupled to said first hub such that said work engaging face of said first cleaning member projects in a first outward direction;
and,
a second cleaning member having a work engaging face, said second cleaning member being removably coupled to said second hub such that said work engaging face of said second cleaning member projects in a second outward direction oppositely oriented relative to said first outward direction,
wherein said first end of said first elongated body portion is shaped so as to define a mounting cylinder, and further wherein said second elongated body portion comprises a first half section including a first pivot half section with a first neck half section projecting therefrom, and a second half section including a second pivot half section with a second neck half section projecting therefrom, said first and second pivot half sections being rotatably mounted to opposed ends of said mounting cylinder such that said first and second neck half sections are positioned in an abutting relationship.
