The Scout is the newest member of the Simplicity lineup. It's a powerful canister that puts more control at your fingertips. The Scout has a digital panel that lets you control the power level depending on your floor type. 
 
Retractable cord; extendable metal wand; large wheels and caster; multiple filtration layers: these are features all included and will enhance your cleaning experience. An indicator light on the digital panel lets you know when its time to change the bag. 
 
The Scout Plus is the enhanced version of the Scout canister. Instead of the combo floor tool, the Scout Plus has a turbo power nozzle with a durable metal brushroll and headlight. The handle on the hose has wireless control of the power level - it syncs to the digital panel.
