Available from Grabo (Nemo Power Tools), the Ottovac Digital looks like a traditional suction cup but uses a built-in electric motor to pull air and hold vacuum automatically on smooth, non-porous surfaces (like metal).
The tool provides a steady hold rated for up to 220 lb.
Meanwhile, the digital display shows current pressure readings in either psi or bar and gives a real-time estimate of the cup’s safe working load in pounds or kilograms. This takes the guesswork out of knowing how much the cup is actually holding at any moment.
