Handheld Vacuum Cleaner is a device comes with an comfortable shoulder strap and a brush and hose for easy cleaning. They have the motor and dust collector (using a bag or bagless) in a separate unit, usually mounted on wheels, which is connected to the vacuum head by a flexible hose. Their main advantage is flexibility, as the user can attach different heads for different tasks and maneuverability(the head can reach under furniture and makes it very easy to vacuum stairs and vertical surfaces).
