Name the program: android cleaner kills crew

I'm trying to remember which franchise this TV ep is from:

The lead characters find a spaceship. All the crew are missing/dead. Only "survivor" is an android, responsible for maintaining ship including cleaning. After detective work, at the end it turns out the android went a bit mad due to isolation for long periods in space and blamed the human crew for creating the mess he had to clean up, so he killed them so that things would stay clean.

I think it may have been a Trek episode, maybe Voyager?

TIA!
