Cordless Blowers are portable units normally intended for homeowners in indoor or light duty outdoor maintenance. Even though they are less powerful in comparison to gas-powered or electric-powered blowers, they are perfect for sawdust or grass clippings.
The majority of cordless blowers are lightweight, since they require no cord or gas to operate. They are designed for light-duty cleanups. Rechargeable batteries ranging from 12 to 18 volts run them. Though the power may be minimal and operating time may be limited, they are the quietest and the most convenient blowers for non-commercial users.

Backpack Blowers
Backpack blowers are more commonly used by professionals and are mostly powered by 2-stroke gasoline engines. The harness, which has a blower fit into it, is worn on the operator's back. The engine and fan are also placed on the backpack frame with a hand-held hose and spout to direct the airflow. Backpack blowers are powerful, convenient and have larger, more efficient fuel tanks and air filters and therefore, longer duty cycles.
Blowers
There are many types of Blowers -- leaf blowers, industrial blowers, snow blowers, etc, Each type has different subtypes such as backpack, handheld, corded and cordless, wheeled, electric-powered and gas-powered, and so on. Each type and subtype differs in function and purposes. For example, while some of them may be specifically manufactured for home maintenance, other more powerful units are aimed at commercial users.
Blower Fans
Fans utilize power from a motor to generate a volumetric flow of air at a given pressure, and are considered low-pressure air pumps more often than not. A propeller converts torque (turning force) from the motor (typically permanent split capacitor AC induction motors or brushless DC) to increase static pressure across the fan rotor and to increase the kinetic energy of the air particles.
Leaf Blowers
Leaf blowers were first manufactured in Japan during the 1970s, and made their debut in the Untied States towards the end of the decade. The annual sales by 1990, reached an estimated 800,000 in the country. It has become very popular due to its efficiency and effectiveness in ground maintenance. Today, leaf blowers are used by almost every family for cleaning patios, lawn trash, leaves, etc.
