The DeWalt and Grabo Hand-Held Suction Lifting Tool-providing up to 265- and 375-pounds lift capacities, respectively-will reportedly work on a wide range of surfaces (non-porous, semi-porous, rough-textured). The tools' built-in pressure sensors automatically control the battery-powered vacuum pump to produce and maintain the required degree of suction. They both reportedly create, within seconds, a secure seal to most any surface, and both feature a digital pressure-gauge display screen, an audio alarm, and a double-action button.
