OTTOVAC
The electric suction cup

OTTOVAC By GRABO

Introducing the OTTOVAC by GRABO, a groundbreaking power tool designed to revolutionize glass handling and installation for glaziers. The OTTOVAC is a portable electric vacuum cup that simplifies lifting and placing glass and other smooth, flat surfaces. Unlike traditional pump-action suction cups, the OTTOVAC achieves a secure hold with the push of a button and releases pressure just as easily.

Eliminating the need for manual pumping, this tool integrates a revolutionary automatic on/off sensor that maintains optimal vacuum levels. The sensor automatically activates the pump to build suction and stops once the necessary vacuum is achieved, preventing over-suction that could damage or “pop” the glass. Should suction levels decrease, the tool re-engages, maintaining a safe hold throughout use. When the vacuum pressure in the cup reaches -55 kPa, the pump stops after a brief delay; if it drops below this level, the pump restarts automatically to ensure stability.

The OTTOVAC safely supports up to 150 kg (330 lbs) and is powered by a high-performance lithium-ion battery with two single-cell 18500 Li-ion batteries. This battery technology ensures a consistent, long-lasting power supply for both professional and DIY applications.

Charging is simple with a Type C USB port, allowing the OTTOVAC to be recharged from various sources, including computers, wall adapters, or power banks, offering flexibility and convenience for any work environment.
