Hand held steam cleaners

I bought one of these in the Hope it would half the time spent cleaning especially the kitchen tiles , windows etc as well as the bathroom. But it came I unpacked it. Filled it with water , cleaned a small area ,but then when the water needed refilling, I had to wait ages for it to cool before I could release the top to refill, also holding down the steam button made my thumb ache , so it’s going back , having to wait half an hour before I can refill defeats the object of a time saving gadget,
Has anyone else got one or a recommendation , I did like the results on the small are I did steam clean ?
