I'd be working at about the same rate in a typical furnished office situation, but with an assistant. Last Saturday we did just over 400sq.M in 5 hours.

For the benefit of those who haven't followed the discussions on this topic elsewhere, I would agree with you that a T/M will always remove more soil, but in some situations, a low moisture system such as Dry Fusion will actually leave the carpets LOOKING cleaner. My experience, and others, is that the protector in Dry Fusion is leading to the carpet looking cleaner for longer and extending the cleaning intervals. Then we have the situation which I will have in 2 weeks time cleaning an office block in London. The van will be parked a taxi ride away. There is absolutely no way a T/M would be allowed to be parked there. Ever!
As has been said on many occasions by many people. A machine is just a piece of kit. Every cleaning system has a valid and valuable role within the marketplace. What's more important is that it is used correctly and for the right reasons.
Safe and happy cleaning:)
