I have a Millennium that has over 110,000 washes on it and it hasn't missed a day yet. An hour here and there for routine maintenance but nothing serious. You should know that Futura may be phasing out the Millennium as they have a new machine, The Impulse, that incorporates all the good stuff from the Revolution and the Millennium, plus adds a turbo arm to take care of the front and back where the Futura systems were lacking before. Check with your distributor for more details. Just so you know, I am a distributor for Futura in Houston.
