I had great hopes for this hand-held steam cleaner. I tried it out on my bike yesterday, focussing on the snowflake rims and other parts of the motor. Does it steam? Yes, like a baby dragon. How effective is it? Well, imagine if an airbrush had a steam attachment. The target area is very, very small, like 1/4" in diameter. It would take a long time to clean anything very large, like a motorcycle. The brush attachment seems to help some, but its diameter makes it hard to get to those "hard to reach" spots. Plus, it only holds 9 oz. of water, which limits its efficiency even more. I think it will work fine for parrot cages, but my experiment only made me realize how dirty my bike is. :) Today I'll try it together with some degreaser. The whole idea was to avoid the degreaser, but that isn't an option. It's more of a toy than anything else. barbz
