Wood's Powr-Grip Vacuum Cups
Wood's Powr-Grip Vacuum Cups were created especially for glass handling and have become the industry's and glaziers' go-to tool all over the world. These pump-style vacuum cups enable the consumer to "place a handle" where and when they need it on flat glass, curved/bent glass, auto glass, pattern glass, stone, or any nonporous material. Wood's Powr-Grip V suction cups aren't like standard suction cups. They can provide a more reliable hold. Due to the whole face of the vacuum pad making contact with the glass, they can be used on glasses of almost any thickness with little chance of injury. The substance being treated releases quickly and easily, leaving no "after-stick" or residue behind.
The Woods Power-Grip 8" Flat Vacuum Cup model has a flat vacuum pad 20cm in diameter. A load capacity of 125 pounds per vacuum cup. A durable metal handle, fast attachment on smooth, nonporous flat surfaces, and ideal for use on glass and other smooth, nonporous flat surfaces. Not so versatile, is it? It also has a Red-line indicator that warns users of any vacuum loss. There's a Check valve feature that allows for repumping without loss of remaining vacuum and a release valve lever that permits quick and complete release. Lastly, it comes with a protective carrying case.
The GRABO Electric Vacuum Lifter is a cordless suction cup lifting system that uses an electric vacuum pump to create a strong suction and secure it to almost any surface. It operates on a variety of surfaces, including rough, porous, and wet ones. It's handy for repairing large-format tiles and handling tiles that have been back-buttered or primed.
The GRABO Electric Vacuum Lifter has a lifting capacity of 375 pounds. Plasterboard, checker plate, drain covers, worktops, doors, glass, stone slabs, concrete pavers, flagstones, textured tiles & glass, and many other surfaces are ideal. The GRABO Electric Vacuum Lifter is particularly effective on porous or rough materials (wood, concrete, rock, gypsum boards, natural stone tiles). A regular hard rubber suction cup wouldn't be able to hold. Air will pass through porous surfaces, causing a vacuum cavity formed by a standard suction cup to collapse after a few seconds. The GRABO works well on these surfaces because it continuously pumps out air faster than air leaks through the material. The GRABO Electric Vacuum Lifter is simple to use, with two buttons: a green one for simple vacuum pump on/off operation and a red one for fast suction pad release. It is an entirely cordless device, powered by a 14.8v Li-ion battery pack that lasts 1.5 hours of use and charges in 2 hours. Two battery packs are included with each lifter set to make it easier to handle bulkier materials. The device has two anchoring points where straps can be attached.
- In comparison to the Wood powr Grip vacuum cup, it is a lot easier to handle. With Wood's Powr Grip, the user must manually pump the plunger before attaching itself to a surface. And then, there is a back lever the user has to activate to release manually. It is not as tedious as I make it sound but having to deal with buttons is a lot easier, which is what the GRABO vacuum cup is activated by.
- Wood's Powr Grip Vacuum Cup isn't suitable for ALL surfaces, which means you can do a lot with it, but not much. The tool is excellent if you're dealing with flat, smooth, and nonporous surfaces like glass. You could say it was made explicitly for glass handling, whereas GRABO is the exact opposite! It's particularly great with porous, hard-surfaced materials like wood, concrete, rock, gypsum boards, natural stone tiles. Not only that, but it is also effective for smooth surfaces like glass.
- There are many restrictions with the Wood's Powr Vacuum Cup when placed side by side with the GRABO electrics suction cup. For instance, Wood's Powr suction cup hates Cold Weathers. It hates winter but loves summer; they are not designed for use at temperatures below 10° F or above 120° F (-12 & 49° C). The GRABO doesn't have such restrictions.
- Wood's Powr Vacuum Cup hates dirt. If the hand cup of the Wood's Powr VacuumPower does not function normally, there's a chance that the malfunction is due to the dirt that's on the cup face, or perhaps it's just in need of service. You are advised to first clean the cup face according to the directions to follow. With GRABO, dirt doesn't affect its efficiency. It's indifferent towards the dirt. Its users do not need to clean the surface or dry it before use. GRABO will attach itself firmly to dirty, wet, and even rough surfaces.
- For maintenance, both tools have rubber pads that are eventually going to wear out. Hence, the need to replace them once every two years or when damaged.
- Both tools are handheld and cordless.
There are many more differences and similarities, of course, but looking at the picture, it doesn't matter as long as they do what they are manufactured to do. If you have a task at hand, pick whatever tool works best for you.
