ABSTRACT:
A rechargeable snow removal device for displacing snow from a variety of locations may include a portable frame with a plurality of wheels. Further, the device may include a primary snow intake section connected to a front end of the frame, a power-actuated vacuum mechanism, and an exhaust nozzle for discharging snow away from the frame. Also, the device may include first and second power sources, preferably a power cord and rechargeable battery respectively. A mechanism for directing and interrupting power from the first and second power sources to the vacuum mechanism may also be included, such that the device may continuously receive power from at least one source. A power distribution interface may be controlled by a user interface and may operate a plurality of switches to direct power from the sources accordingly. Additionally, an auxiliary snow intake section may be included for collecting snow in limited space areas.
