The Cyber Clean is a... some sort of... a thing designed to help stick to and pick up the human waste (I mean dead skin and hair, nothing rude) that tends to accumulate wherever humans sit still for long periods of time. It's uses a "combination of viscosity and elasticity" to sink into recesses and pick up dirt. It was probably developed by NASA as a way for astronauts to get bits of pasta out of the command console.
It can't do anything about the vast collection of movies and images you may have accidentally saved to a folder, though, while "researching" on the internet. You'll have to delete that yourself in a hurry when the police kick down the door at 4.00am.
