Who doesn't want to get their work done faster? A surface cleaner is included that cleans faster and more effective than nozzles alone! Equipped with a Honda GC engine, this hard worker provides you with optimal performance around the house. Includes a welded steel frame and 12" Never-Flat wheels. MegaShot is a Simpson staple in quality use and workmanship, so we don't think you'll be disappointed in the way it operates (or the way it feels!). With the surface cleaner bundle, you really can't go wrong at this price point!

Simpson went above and beyond on this model, combining great components with a low cost! This model features a powerful Simpson 420cc Commercial Series engine and a triplex pump that delivers 4 GPM at 4400PSI! There isn't much under the sun you can't clean with those specs. The adjustable unloader lets you adapt to the job at hand without fuss, increasing or reducing PSI on demand. You won't find that on consumer models. The 13" pneumatic tires absorb vibration and are ready for construction-grade terrain. The triplex plunger pump design runs cooler and lasts longer than axial pumps, plus they can be rebuilt if you ever had an issue. All around, our favorite recommendation for this category.
