Hi Guys, Thanks for the kind words. Most machines ( rotary) I looked at modifying before I built from scratch used 5" wheels and they were tough to go up certain steps that had a big overhang on the step itself. These 6" I find climb steps very easy, even with a full tank. I think part of the ease of use is the precision sealed ball bearings that spin very easily and the 3rd wheel that helps to distribute the weight (89 pounds empty). You can remove the tank and carry up also as the Mini does have a front lift handle. If the tank stays in and its not completely full I use the chassis or base lift handle and one of the handles on the tank. I never carry up the steps, I use the wheels. The lifting part was in and out of the van. I still clean and use the Mini to go up steps in one property that has 8 buildings, each with 2 floors. I wanted to get this on video with my 4 11" wife taking it up steps but I already was running long on time.Hope this helps.
