I have one of them too and does have a splash gaurd?? Personaly it shouldn't be advertised as an upholstery tool....
It can be used as a stair tool (even tho that little solution pipe that is attached to it is a royal pain in the ars*!! when it comes to doing the edging)
I use mine to great effect for doing behind toilets, and other tight spaces for example, the space between the side of an immpossible to move wardobe and the wall. If your wand is to wide for it etc
You should save your pennies wayne and buy the CFR hand tool. They are a tad pricey at around £350 after VAT but they last YEARS (aparantly) and as soon as you use one you'll think its the best money you spent
IMO does a better cleaning job than the drimaster handtool and the drying times are great once you have mastered it.
