SentinelThe Sentinel sweeper is powered by an 83-hp Cat 3054C diesel and uses oil-bath, sealed, multidisc brakes. The 3.4-cubic-yard stainless-steel hopper can be elevated to 9.5 feet for dumping. This four-season sweeper, with its Vario Sweeping Brush option, can sweep around obstacles and on top of curbs. Its center-suspended floating main broom adjusts automatically to surface conditions, and its dry-filtering system for the main brush cleans air to 5 microns.
