Traditional suction cups are only capable of creating a good seal with flat, clean and airtight surfaces such as glass. However, Grabo’s unique seal allows the tool to adhere to rough, etched surfaces.

The maximum surface roughness to which Grabo can attach to depends on the exact ‘profile roughness parameters’ (The geometry of peaks and valleys in the material) and is generally limited to an amplitude of about 2.5mm (0.1 inches). This capability allows Grabo to create a seal with the majority of patterned tiles, pavers and construction materials.

A porous surface is any surface that allows gas to flow through it. Many construction materials are porous to varying degrees. The most common porous construction materials are wood, concrete, rock, gypsum boards and many ceramics and tiles.

Standard “suction cups” can not hold porous materials for more than a few seconds, even if the surface is flat enough to create a seal. A vacuum cavity on top of a porous material will quickly fail as air seeps in through the material.

Grabo overcomes this and allows secure adhesion to these materials by constantly pumping out a large volume of air at a rate greater than the diffusion rate of air through the surface.

The physics behind the calculation of flow rates through different materials is both complex and interesting. The flow rate required from Grabo to keep a strong vacuum seal against a porous surface is generally described by a formula of generalized Murray’s law:

The flow rate is then multiplied by the surface area under the seal for a given pressure differential, which results in the flow rate and power requirement from Grabo’s internal electric pump, However, as interesting as engineering is, users of Grabo do not need to worry about science. All you need to know is the Grabo is designed to work well on some of the most common porous materials in the industry.
