An improved self-anchoring umbrella, the umbrella comprising a canopy and pole, a retractable auger disposed within the pole of the umbrella. The retractable auger is operated using an electric motor and portable power source, and a switch allowing a user to provide power to the electric motor which rotates a drive head with spiral teeth engaged within spiral grooves in the pole. The umbrella may further include a table portion, and extendable stabilizing legs disposed in the lower portion of the pole. When the auger portion is screwed into sand or other surface and the stabilizing legs are engaged with the surface, the invention provides a stable umbrella for outdoor recreation and other purposes.
