Class M extractors — the class that covers most real site work. Plaster, clay, ceramic, paint, lime, varnish, wood, concrete, cement and screed all fall here, which is to say almost everything that isn't asbestos. Containers run from the compact MIDI up to 48 litres, and AUTOCLEAN models clear the main filter on a cycle so suction holds through the day rather than tailing off. Machine-specific variants pair with the long-reach sander and the renovation grinders. If you're unsure which class you need, M is the sensible default — it costs a little more and covers a great deal more.
