A squeegee with ergonomic handle and non-loosening pivotable blade. The squeegee includes a handle for one of attaching to a pole and holding in a hand of a user, a blade portion pivotally mounted to the handle for side to side pivotal movement relative thereto, and pivoting apparatus for pivotally mounting the blade portion to the handle for side to side pivotal movement relative thereto. A flat longitudinal side of a threaded shaft of a specifically configured bolt contacts, and locks against, a flat longitudinal side of a specifically configured throughbore in the handle preventing loosing and rotation of the specifically configured bolt relative to the handle when the blade portion is pivoted relative to the handle, with the tapering of a head of the specifically configured bolt creating a mechanical advantage of increased friction between the head and the flared portion of a specifically configured throughbore in the blade portion, and with the pivoting apparatus being positioned at a slanted edge of the blade portion and the side of the handle and not the center of the blade portion and the center of the handle preventing the blade portion from hitting the hand of the user when it pivots to an extreme.
