    1. Battery life very long
    2. Easy to use
    3. Works on any flat surface so it has so many other uses
    4. Made by GRABO
    5. Automatically reseals

    Surface has to be smooth, the professional Grabos I think allows a lot more give. Where if there are any ridge lines, it will not sanction. Though this is expected.

    Most people know the brand GRABO, so it was not sure why this device was also called OTTOVAC. Regradless it works great! I used this specifically to install 12×24 tiles and it would have been a PIT if I did not have this. Besides easily holding the tile and placing it on the thin set, it also allows you to “wiggle” the tile around to make sure you have full contact and coverage.

    I purchased this to help me lift and carry computer rack enclosure walls. Each weigh about 68 pounds and measure 40″ W x 75″ H x .5″ thick. I had two concerns when purchasing this. Would GRABO warp the wall? Would it hold without slipping? GRABO did not warp the wall and held on tight without slippage. I can trust this unit for my work. I like that it will automatically trigger the vacuum pump when the suction decreases. It happened while carrying a wall. It did not slip before or during the pumping. I plan on using this for glass chair mats, as well.

    I never thought a small accessory like this could make such a big difference, but the GRABO Brace Seal has been a game changer for me. 5 stars!

    This foam seal has improved the performance of my GRABO vacuum significantly. No more leaks!
