Well, let's see...
The Cleaner appears to have recovered, so you probably can't do a lot without stunning it again.
It's indiscriminate, so you might be able to buy time hurling debris at it. Whether this would make it larger, more sluggish, if it's smart enough to only eat living allies and not crates of tourist fodder, is all up in the air.
It's probably dumb as a rock, so you can probably lure or otherwise attempt to play it without much incident. I suspect it's too dumb to properly trick, but getting it to favor attacking one of you over the other is probably a simple matter of proximity, for instance.
It has no visible eyes, is covered in a metal shell, and is made entirely of goop. Almost assuredly this thing sees through electromagnetic fields or some other such nonsense. Or its whole body is an optical/chemical/auditory sensor in addition to being resilient murdergoo, in which case external screaming intensifies. But more likely you can blind or lure it with the right electronic fuckery, such as might be found in the ship's engineering or reactor.
Since it scours everything it touches, it probably doesn't have a very good grip, which raises the feasibility of just venting the thing. Also synergizes with presumed dumb-ness in luring/lack of creativity once the suction starts. How bad a grip is up for debate, unfortunately.
We're not sure how the thing handles sturdy materials, like locked ship doors. It might just bore through them, but I suspect it's a little more discriminating to avoid eating the whole ship it's turned loose on. It might ignore them, it quite likely slithers through air ducts looking for delicious meats. Nonetheless, I'd give just running through and shutting a door much better success rates than against more intelligent foes.
