    Changed our business forever, I don’t need to send two guys to install cabinets anymore, one guy can do it easily.

    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.

    Let me start by saying, if you can see this being useful, stop right here and just order it! I chose the older analog display model , well cuz I’m cheap… and this works just as well only cheaper!! Hands down best investment ever. So useful , picks up heavy natural slate material no problem , even the ones with natural uneven surfaces, unless it’s way uneven, but for the most part I’m completely blown away with how absolutely useful this thing is !!!

    Had borrowed one from a friend last winter and it worked well. I bought my own for a specific project I was doing. This tool works excellent. I laid a 175 sq.ft. stone floor (about 50 - 24""x24""x1 1/4"" stones and cuts) The stones weigh about 50 lbs and have a rough thermal finish. The Grabo lifted with no problem. I was showing it to a carpenter and even on a plywood wall I could not pull it off . Highly recommend this tool.
    Also only used half the battery life over the two days of setting stone.
