Query: Safe buy if you are unsure

After researching most of the units out there, I finally chose the McCulloch. If it is grout you want to clean, this one works. Easy to use, good steam, still takes some scrubbing, but if you saw my grout before using this unit, you would be amazed. I had settled into accepting my grout would just be a darker color for now on. NOT! So, if you are unsure, not that my word carries the weight of gold, this unit works like it should to my specifications. IT is not magic, but it works reliabley. Just my thoughts.
