The Carpet Pro CPU-2 is a true commercial machine and includes many conveniences not found in a typical commercial machine including an Easy Bag Change System and a By-Pass Motor System. The Carpet Pro CPU-2 also uses a Motor By-Pass System which means all of the dirt goes directly into the bag and NOT through the motor. This means you can pick up a nickel or screw and not worry about braking a set of fans which is a common problem in many other commercial machines. Instead of using plastic or wood for the brushroll or plastic for the baseplate, the Carpet Pro CPU-2 uses metal for both part increasing durability and preventing a broken brushroll or baseplate. The brushroll is sealed off with rubber end caps preventing hair and debris from getting caught in the brushroll and melting either the side wall of the machine or the brushroll; a problem commonly found many other vacuum cleaners. The Carpet Pro CPU-2's brushroll uses Commercial-Grade Stiff Gold Bristles to ensure you are getting the most dirt out of your rugs as possible. The Carpet Pro CPU-2 has a hose inlet located at the back of the machine allowing the user to insert an optional hose and tools if ever necessary. The Carpet Pro CPU-2 uses a commercial grade 40-foot cord so you can plug in once and clean an entire floor in many cases! The cord is heavy duty and yellow so the user is aware of the cord at all times. To prevent you from spending time unravelling the cord, the Carpet Pro CPU-2 has a Quick Cord Release located on the cord hook. This allows for simple hassle-free cord removal. Since the handle takes a lot of stress when used the Carpet Pro CPU-2 has a metal handle for increased durability. The User has to be comfortable while using the machine which is why the handle has been fitted with foam for comfort. The Foam also prevents slippage while the machine is in use. The Built-In Furniture Guard helps protect furniture and walls if the this vacuum were to ever bump into walls or furniture.
