The sweeper also has a seat occupancy switch that shuts down the engine if the operator leaves the seat and a Thermo-Sentry hopper sensor that alerts the operator to excessive heat in the debris hopper.
Tennant says productivity is improved with easy access to all routine inspection and maintenance points as well as no-tool dust filter and brush change out. The sweeper’s nanofiber canister filter lasts three to five times longer than a traditional panel filter, according to the company.
Options available include dual side-sweeping brushes, vacuum wand and steel tower bumpers. The S20 is also available in a battery-powered version.
