How is this ethnic cleansing if they're only targeting non-citizens and leaving Roma who are citizens?
EU free movement is less 'free' than many people realise; there are restrictions on it that most states never actually bother to enforce.
Namely, freedom of movement is basically for the purposes of work. You can move for other reasons, but the receiving state is entitled to deport you on grounds of public security, for example if you get a criminal conviction. They can also bar your entry if you're, say, an extremist. Also, if you're deemed to be an unreasonable burden on the public purse, they can toss you out as well.

So, they could be deported back to Romania or whichever country they hold citizenship of, but they're not going to be welcome there either. And there would be considerable public support for it.
Anyway, there are probably plenty of other 'drains on society' that could be deported, but you don't see them being targeted.
