These type of machines are aimed at large contract cleaning firms who consider 14k to be small change.
When you compare Ionics prices to these cleaning firm's labour cost then it is really peanuts. Say you have 200 employees on £15k a year and 10 managers on £25k a year and one area manager on £50k a year then this equals over £3 million a year in labour cost before tax and NI so spending £14,000 on a machine is nothing to them.
