As typified by prior art U.S. Pat. No.: 2,057,142 (Fry--Oct. 13, 1936); U.S. Pat. No. 2,738,580 (Rice--Mar. 20, 1956); U.S. Pat. No. 2,855,668 (Ottenad--Oct. 14, 1958); and U.S. Pat. No. 3,830,310 (Williams--Aug. 20, 1974): plunger-actuated surface-treating devices extending along an upright longitudinally extending central-axis and having a downwardly thrustable plunger member toward a lower-end surface-impacting tool are suggested in prior art teachings. However, such prior art plunger-actuated surface-treating devices are fraught with several disadvantages and deficiencies such as, but not limited to: are not structurally adaptable to efficiently dislodge variously randomly encountered topical-surfaces from their underlying substrates; are operationally unreliable for their intended purposes; are too heavy to be conveniently and reliably operated by variously physically endowed persons for the surface-treating intended purposes; and are not economically acquirable nor maintainable by the intended operational population.
