    I was skeptical, thinking the electric pump was gimmicky. But the cup appeared robustly constructed and Grabo’s electric vac cups are successful in their industrial line, so I ordered the Ottovac, which is in a more conventional form factor.

    It is truly robustly constructed. I particularly like having a steel handle frame. While there are a number of plastic parts, including much of the pump itself and the pressure release, they are non-stressed parts. Weight bearing parts are stout and the weight ratings and limits reflect that.

    My need is to assist in appliance and furniture moving, often simply to get items away from walls, over obstacles like rugs and sills, and to put them on dollies. Vac cups provide handles where you need them and, when the item is vac cup appropriate, MUCH faster and easier to use than just about any other method aside from an electric or hydraulic lift.

    I tested the Grabo Ottovac on wood furniture, on glass, and on appliances. The furniture items were mostly clear wood finishes – poly, lacquer, etc. – with somewhat porous surfaces. The Ottovac did lose vacuum on these, but the pump kept the vacuum in the green zone, allowing me to use the cup with no issue. I wouldn’t carry something any distance this way, but for a quick lift, it’s terrific and something that’s often either not possible at all or dangerous with a manually-pumped vac cup. On the non-porous surfaces, the Ottovac works perfectly and holds vacuum like any good vac cup … but is easier to use.

    A couple of small things: First, I do have to give a bit of a push on the cup when starting in order to get the vacuum to grab initially. Second, the release “button” is wonderfully easy to reach and use, but is almost TOO easy. An inadvertent release on a vac cup can be very dangerous. I wouldn’t mind having the release positioned down somewhat so as to make it less likely to hit it accidentally. Finally, the metal handle is smooth. It feels good but is slippery if your hands are wet or sweaty. Use gloves or tape-wrap the handle.

    This is a very good product, well-made, and effective. A few tweaks and it would be perfect. As it is, it’s a substantial step up in usability from the value-priced cups on the market. You pay for that, but IMO it’s worth it.

    The only things I’ve been unable to grip with mine are objects in which either:
    A. …the surface is SO covered with particulate matter (e.g. covered in sand, dust, powder/flour, etc.) that the device is unable to form a seal, or…
    B. …something whose surface is not only irregular, but is also too porous to draw a vacuum against (roll of carpet, pile of pumice stone, a screen door, etc.), or…
    C. …something whose surface isn’t capable of supporting itself under any circumstances anyway (a pool of water, a pile of gravel, etc.)

    …and you know what? That’s all TOTALLY FAIR.

    One doesn’t pick up one of mankind’s most effective electromagnets and then grouse about it “”not working on non-metallic items””, or one of the world’s most-powerful acids, only to whine about it being “”unable to dissolve glass,”” either (or, at least, not without getting promptly lumped into the category of “”humans I hate on principle””).

    I CAN lift plywood, drywall/sheetrock/gypsum board/hardiback, tile, granite, marble, glass, metal of any sort, appliances, floor tools, cabinets, furniture… and gods only know what else I’ve yet to discover and/or simply haven’t thought to experiment with yet! Yanno the old saw about “”it’s not heavy, it’s just awkward!””? It’s genuinely shocking how true that actually is. We were able to move a California King mattress wrapped in plastic with NO problems. It was EASY with something to actually get a positive grip on.

    Hell: I was able to stick ONE of them to a finished ceiling, HANG PULLEYS from its integrated mounting brackets, and use IT, in turn, to HOIST A 90lb dust collector EIGHT FEET UP A WALL, then REST IT ATOP A SECOND ONE stuck to a bloody FINISHED INTERIOR WALL, tie off the rope, and leave it there – supported only by their respective suctions – until I had time to climb a ladder and lag bolt it in – OVERHEAD, AND BY MYSELF.

    Izzy Swan – genius inventor and all-around roaring badass – has done some really, REALLY cool brainstorming videos surrounding the use of them, too (I’m not affiliated in any way, just trés impressed):

    Yes: they’re expensive. But, I assure you: you’ll be stunned how many applications around the shop you’re likely to find.

    I was hesitant to try the GRABO Brace Seal, but I’m so glad I did. It’s made my work so much easier and more efficient. Highly recommend!
