Abstract: A brush and roller cleaner includes a hollow canister to receive a spray wand. A control knob pivots with respect to the canister to direct pressurized liquid from apertures of the spray wand. A top cap assembly mates with the canister in one of two positions, 180 degrees offset from one another. The top cap assembly has a tool holding assembly that is capable of holding a paint tool or roller. The tool holding assembly rotates in response to the liquid output from the spray wand apertures. The top cap assembly is capable of holding a roller in a first or second position. The roller rotates within the canister in response to the liquid output from the spray wand apertures to clean the roller cover. A handle for the cleaner supports a roller frame clip for holding the roller in a first or second position.

Abstract: A battery pack with a housing, at least one battery cell contained within the housing, a first terminal and a second terminal. The housing includes a substantially ovoidal surface which is substantially symmetric about a first axis of symmetry and a second axis of symmetry which is transverse to the first axis. The surface has first and second substantially linear terminal openings. The first opening extends substantially parallel to and is non-coincident with the first axis, while the second opening extends substantially parallel to the second axis. The first and second terminals are disposed within the housing adjacent to the surface. The first terminal is accessible through first opening and the second terminal is accessible through the second opening. A device for using the battery pack is also provided.
