Grabo GRABO-NG2BFB Cordless Vacuum Suction Cup Lifter Kit


GRABO NEMO PORTABLE ELECTRIC VACUUM CUP A new and revolutionary way to lift and handle tiles, Glass, concrete, dry walls, plywood furniture and much more. Designed for flooring professionals, Glass installers, carpenters, movers, construction workers and more. Nemo Power Tools builds quality premium tools which are built to last and get the job done every time. Each product is the result of years of great engineering, development and non-stop quality testing. Grabo is manufactured in-house in our privately owned and operated factory, where we control the full cycle of production and quality control. No third party contractors are used in the production, assembly, testing and packing of Grabo. Each Grabo is marked with a serial number and individually tested for pressure and strength before it is packed for delivery. In addition, several units of each production batch are tested until destruction in our own-site lab.

Lifting force under different conditions

Max Lifting Force

This table provides a rough estimation of the max perpendicular adhesion force and max parallel adhesion force on different materials. These values may vary depending on material and surface conditions.

Perpendicular Hold Parallel Hold P/P Ratio
Glass 170kg (375lbs) 120kg (265lbs) 0.7
Metal 110kg (242lbs 110kg (242lbs) 1
Plastic 100kg (220lbs) 100kg (220lbs) 1
Wood 100kg (220lbs) 65kg (143lbs) 0.65
Ceramic Tile 170kg (375lbs) 120kg (265lbs) 0.7
Rough Concrete 80kg (176lbs) 80kg (176lbs) 1
Drywall 75kg (165lbs) 65kg (143lbs) 0.87
Rough Slate 80kg (176lbs) 80kg (176lbs) 1

Pressure to perpendicular lifting force conversion
For a more accurate estimation, check the pressure gauge on your Grabo and use the table below to convert pressure values to max lifting force values. (Parallel holding force values can be calculated using the P/P ratio provided above for different materials.)

Pressure (bar) Max perpendicular holding force
-0.8 170 kgf/ 374 lbsf
-0.6 128 kgf / 281 lbsf
-0.4 85 kgf / 187 lbsf
-0.2 43 kgf / 94 lbsf
-0.1 21 kgf / 47 lbsf
