m/s aggitation with micro fibre cloth
the dri master was from hydra master, good price
expensive but worth it, cant recall at the moment how much exactly, but like any thing in the end its worth paying for, as dring times are minimised, cleaning time is cut by around half an hr , on an average suite.
Mike will be able to give you a clearer verdict on both tools, as he has used both , but to me its swings and roundabouts.
