Abstract
Abstract A vacuum cleaner is provided having a handle assembly (200) and a floor engaging unit (100) pivotally mounted thereto, which includes a vacuum pump formed by a motor mounted to a base. One or more lamps are provided within the floor engaging unit (100) for directly light forardly of the vacuum cleaner through a horizontally elongated lens. The handle assembly (200) includes a housing (201) pivoted to the floor engaging unit (100), and a handle (202) extending from the opposite end thereof. A rigid or semirigid dirt tube extends longitudinally in one side of a recess in one side of the housing (201), and has a lower end coupled via a flexible tube to the outlet of the floor engaging unit. The dirt tube has a forwardly extending port in its other end to receive a disposable dust bag adapted to be removably assembled in the front recess. A further recess is provided in the rear of the housing for releasably receiving a rechargeable sealed lead acid battery assembly box, which includes the battery, a recharging circuit including a recharging light, and a circuit breaker that is accessible at the rear of the vacuum cleaner for being manually reset. A control board is provided at the upper end of the housing (201), including a switch enabling operation of the machine either with or without use of the lights. An indicator, such as a row of LEDs is also provided on the control board, to indicate the charge condition of the battery to the user.
