It may have a small diameter (12") but with the right amount of GPM (2.0+) behind it, it'll clean an area in one pass! It has the splash proof skirting, quick connect tip to the wand, and a high-pressure filter. Westinghouse also offers all the replacement parts for the cleaner; instead of expecting you to buy another unit if it breaks. Which is something, as a DIY'er, I appreciate.
