Discover the GRABO® HighFlow

The ultimate cordless power tool that grips even the most extremely porous pavers.

Where GRABO® leaves off, the HighFlow picks up. This is the most powerful tool we've created. With a vacuum flow rate of 1500 cubic liters per minute, there has never been a handheld, portable vacuum tool this powerful that grips the most porous materials.

With our brilliant new pistol-grip design, easily lift, grip, move, or install heavy, porous materials on the job site with precision and confidence.

The GRABO® HighFlow is GRABO®'s most advanced tool, offering more power and improved vacuum technology, revolutionizing how challenging objects are handled. Its innovative design features a SMART CUT foam seal and a user-friendly T-handle, significantly simplifying and improving the ergonomics of laying outdoor pavers.

Tailored for efficiency, the GRABO® HighFlow excels at handling rough, highly porous materials such as Dry Cast Pavers, ensuring a firm grip and safe handling, even on the most extremely textured material. It also offers a diverse range of suction plates, available in sizes 300×300mm and 400×400mm.

The top of the tool features a large LED digital display that shows your real-time PSI or BAR pressure, so users will always know how much pressure the tool is exerting. With our new powerful GRABO® 20V (18V EU) battery, the new HighFlow is rated to lift up to 242 lbs (110 kg) when used with our 400mm suction plate.

HighFlow Airflow Control

Dial in the airflow you need

HighFlow's high-volume pump pulls air faster than any other GRABO®, so leaky and extremely porous surfaces can still hold a strong, stable vacuum. The clear analog gauge lets you watch pressure build in real time and confirm every grip before you lift.

A balanced, ergonomic handle stays comfortable through long sessions, while the dual-battery system keeps the pump running on demanding rough materials.

High-volume vacuum, built for porous lifts

The HighFlow pump moves significantly more air per minute than a standard GRABO®, so it can pull a working vacuum on materials that would defeat a typical lifter - raw timber, rough concrete, untreated stone, and other open-grain surfaces.

Watch the digital display build to your target pressure, then let the pump cycle automatically to maintain the seal while you move and place each load.
