Okedokee, here are my droids:
The Janitor Droid is a General Grievous from the Jedi vs. Sith Battlepack (same as Sneak Preview) with a dollar store figure's head and boots. The hands are from a Darth Maul figure (the one with the spinny right hand).
The Bucketbot is a POTF2 R5-D4 figure with the head cut off. I added some cut up fake credit cards for the "rim" and to cover up the droid's innards.

Backstory on Janitor Droid:
The Crusader Class Assassin Droid was employed by Count Dooku to assassinate a high ranking politician on Tralfa, a planet that refused to submit to the demands of the Separatists. Unfortunately for Dooku, the Republic forces arrived in time to reinforce the Tralfa Home Defense Army and the Crusader Class Assassin Droid was captured intact (the auto-self destruct was damaged in the skirmish). The targeted politician was a proud man and decided to "show" Dooku and other Separatists that he was not afraid of their thwarted assassination attempts; he converted the Crusader Class Assassin Droid into a Janitor Droid for the Home Defense Army Training Depot.
- The droid's jetpack was converted to a cleaning chemical dispensing unit and his machine gun/energy bladed hands have been replaced with rubber gloves. His advanced night-targeting system has been replaced with a black light for maximum dirt and grime removal.
