Buying a vapor steam cleaner

Soon,we will be moving to our new house and since the previous owner left the house for almost 5 months already,I guess we have to do some general cleaning.We have seen the place and we know that it has many dirts and stains on the floor tiles and grout and the other places of the house.Surely,it's hard to clean it,so we need to buy a home steam cleaning machine.We've seen a lot of good vapor steam cleaners at Refresh Your Home site,which give us some ideas and infos on what's the best to buy and how to use this multi-purpose appliance.Now,we still have to decide which one we have to buy.
