what do you expect your cleaner to have done

[festiveface]

in say, 2 hours?

whats feasible to expect to be done in that time in a big house?

depends on how big the house is I suppose.

clean bathroom (s)
wash/hoover floors/carpets
clean kitchen
tidy clutter

That would be 2 hours worth I think.

what could you get done in 2 hours in your house? I think the same is reasonable.

I would say hoover throughout, clean kitchen, bathroom and dust/polish
