Behind the Innovation: Nimo Rotem’s quest to build better power tools

Nimo Rotem, a mechanical engineer and inventor, has significantly advanced the power tools industry through two major innovations: Nemo Power Tools and the GRABO vacuum-lifting system. Nemo Power Tools originated from Rotem’s work designing custom underwater equipment for military and scientific use, including for the U.S. Navy and Israeli Defense Forces. His key breakthrough was developing a pressurized internal chamber within tools that balances the external water pressure, preventing water ingress and allowing drills, grinders, and impact drivers to operate reliably up to 50 meters underwater. This patented technology enabled Nemo Power Tools to serve niche underwater markets where conventional tools fail. Rotem’s second major innovation, the GRABO, was inspired by a rock climbing experience and addresses the challenge of safely lifting heavy, awkward materials on construction sites. GRABO is a portable electric vacuum lifter that uses an electric pump to create negative pressure between its foam seal and a surface, forming a strong vacuum grip even on rough, uneven, and porous materials
