This big machine has superb storage capacity. There’s a clip for the lance, the hose wraps around a handy reel and the cable is neatly stashed on the side. It feels well built, too, with a quiet motor for its size. The long lance and hose give you loads of room to move around, and it performed well in the cleaning test. The price is a little high, however, while the unit is rather bulky.
