Just got the GRABO PRO Lifter 20 for my glass installation business, and it's a beast! The suction is super strong, making it easy to handle large glass panels without any stress. The battery life is impressive, and the digital display is a nice touch. It’s definitely made my job a lot easier
It is not possible to overstate how much I love this item. I love everything about it. Given how long the batteries last, the choice of using AA batteries instead of a proprietary battery pack was hands down the right call. The fact that the device actively monitors the pressure while on will save money. If it didn’t and the device started to lose pressure for any reason, then you would drop your work piece and that could be both expensive and dangerous. According to the manual, this device under absolute perfect conditions has been tested at 440lbs but is only rated for 220lbs.
The thing that really makes me smile though is how compact the device is. I remember watching MythBusters as a kid. In one episode Adam Savage built a suction cup climbing rig to scale a building. It was big, heavy, complicated, and probably cost more than buying four of these. He would have killed for this product back then.
It might seem like allot of money to spend on a suction cup and if you’re not using one all the time it probably is. But if you use big suction cups like this allot then you will be happy to pay for how much pain it will save your fingers.
I was skeptical at first, but the high friction rubber truly makes a difference. My GRABO now works better than ever.

Bought a spare Ottovac Li-Ion battery, and it's been a game-changer. I use my Ottovac for all sorts of lifting tasks and the last thing I need is for it to die in the middle of a project. The extra battery charges fast and lasts a good amount of time. If you’re using your Ottovac regularly, having an extra battery is a no-brainer.
