You can probably make a washing machine spin so fast that it'll pretty much dry the clothes out of the washer. Spinning a drum that fast would probably be a good lawsuit if anyone gets hurt though.
You'd be amazed how much more water you can get out of things like towels with one of those. Chuck something light like a fleece or acrylic jumper in and it comes out dry enough to wear.
I'd venture that the main problem is that it requires care to run, you can't just toss stuff in, and you really can't have foolish teenagers deliberately putting a load all on one side to 'see what happens'.
The load would need to be balanced unless it had impractically massive shielding or some kind of auto-balancing system. Without those, the centrifuge would create a big hazard to itself and anyone nearby.
With some care you can sprag the lid switch so they run with the lid open, and then toss things in when it's going at the 20,000RPM or whatever speed they get up to.
If you can get the insides really clean, you can juice about 60 oranges at once.
