I came on line to see if there was a user guide that had more information, with no luck. In both the user guide and on the box it says the brushes are color coated for specific use, however nowhere on the box, in the user guide, or on line do they explain which color is for what use. It would also be helpful if there were examples of things it cleans or even a video. Extremely disappointed in the information in the user guide and would have tried a different brand had I known the user guide was useless and less than informational. I have had a steamer in the past it also worked great but was very heavy - this one is light, easier to use, and worked just as well. I've only had it a day but it did a great job on my windows and in the bathroom. Have yet to try it on my grill but that is next on my list.
