Abstract
A cleaning device for spherical-shaped covers for light fixtures and security cameras. The device has a plurality of flexible blades with an expandable cleaning pad attached to the tips of the blades. As the device is pushed onto a spherical dome cover, the blades flex outward permitting the pad to expand to the farthest end of the exposed dome. The device is rotated thereby rotating the cleaning pad and in the process, wiping the cover clean.
