I work long hours so I got an extra battery for my Grabo so I don't have to wait for it to recharge. The battery itself lasts a long time and charges pretty quickly. If you’re using your GRABO for big projects or long days, having an extra battery is definitely worth it.
I recently added the GRABO Erguo S1 to my tool collection, I work in construction so this tool eases my back a lot. Its perfect for handling large awkward materials like drywall and glass panels. The build quality is top notch and it feels sturdy. The GRABO Erguo S1 has made my job much more efficient and less physically demanding. Highly recommend it to anyone who frequently works with heavy materials or has to bend down a lot.
I was able to try one of these out from a coworker last Friday. What a device! An elegant and convenient tool. I look forward to ordering my own. It is a great improvement from my home brew vacuum fixture. With some selective attachments I see great potential in not just lifting and holding panels, but also for holding fixtures as I drill or do router template work. This will be like a mag drill for non-magnetic materials. I have always liked the venturi vacuum generators for the shop and the woods grip for everyrhing else. This truly is the best of both. As long as the batteries charge faster than they are depleted in the tool I will be set.

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.
