We've all seen thesetypes of items on the shopping channels and they promise wonders, well, they actaully do. I didn';t want to spend a shopping channel price for one and I liked this item. You will not be disappointed at all !! I know it only has a small tank and would power a staem train, but it last long enough and anyway, after using this for ten minutes, you need a break from all the cleaning anyway. I used it for the first time to clean my oven. I used an old thick towel on the end instead of the little pad as it would have gotten dirty in no time. I took all on 10 mins to clean the inside to a shine. I would highly recomend this product.
