Don't be silly now, they have irrigation for that, Soapy is obviously clued up, it's a hot tub you use whilst having an open top tour of the island.
Anyway, I'm out here pricing up some solar panel work. As Malta is just about the most southerly point in the EU they're having 8,500 apartments fitted with solar panel systems for the expected influx of immigrants from N. Africa.

They're talking about each unit cleaned on a 6 weekly basis.
