OTTOVAC Li-Ion Battery

So simple, these cabinet plates are genius and are real MVP on the job site.

Izzy did it again. Finally a smart way to hang cabinets.

Use these almost everyday moving pavers, awkward hold, but it’s better than bending down all day long.

I gave one to each of my installers for their install jobs. Great tools to have in the truck.

Our installers love using both the grabos alone and the grabos on the seam setter.

The seam setter worked out great, better than my old pump seamer.

The GRABO 90 Degree Stone Seam Setter is a game changer! I was able to achieve perfect 90 degree angles every time on my kitchen counters. I highly recommend this tool to anyone in the business.

I’ve been using it all day and the battery was still full , so far so good 👍 👌 😌

This is a very well made suction cup, that I was easily able to lift over 200 LBS of weight while using. This cup has multiple suction points, automatic shutoff of the pump, gauge, and strong metal frame. The pressure relief, on/off switch, are all easily located near the handle. The automatic vacuum is awesome, very quick to lock on and draw a strong suction. The unit takes four AA batteries, which I used rechargeable batteries, worked great. You can see in the photo, I was getting over .6 bar of suction. I would recommend this suction cup to anyone who needed one.

Hope this review helps you.

I unboxed this and attached it to the side of my safe. Pulled it around the shop. So, I got another one and attached foot holds with ropes to them. Now I’m climbing glass buildings like Spider-Man with them. You could probably pick up glass and tile with them, but I’d rather be Spider-Man, so that’s what I’m gonna do. In a world full of tile setters, be Spider-Man. Kirk out!

Works as advertised, hard to tell, but I am lifting a stove/oven combo in the pic. This thing is so cool, not just for glass, it works on metal and sheets of plywood too. Only have two small gripes, first is the controls are a little fiddlely, you hit the button to start the suction, it turns off automatically when it’s reached proper suction, the only thing you have to get use to is to turn it off before you release it, if you forget to turn it off and hit the release button it will start pumping up again, not a big deal just a small learning curve. The second gripe is it is battery powered and didn’t come with batteries. Again not a deal breaker but it would of been nice. I’m planning on ordering a second one so I have one for each hand. Awesome product.

Review source: Amazon

This is one of those tools that I would think, “that would be nice to have”–now it’s “how did I go so long without buying this?” This suction gripper is a must-have for people who need to move heavy objects with smooth surfaces–not just glass or large ceramic tiles! I found it incredibly useful for moving things like file cabinets–heavy as heck but without a place to grab onto!

The gripper is quick and easy to charge, comes in a nice molded vinyl carry case that snaps securely, with clear instructions. What’s not to like?

Review source: Amazon

This electric suction vacuum cup has impressive holding power. It is well made and all controls are easy to reach and use. It utilizes 4 AA batteries (not included) and comes in a robust protective case. So far I’ve tested this to carry glass and it does an excellent job. I plan on utilizing this mostly to install tile in showers but can be used in wide range of applications.

Review source: Amazon

I am using this to lift and hold 26ga metal siding.
I am not using it to move them but to lift and hold them in place while they are screwed in.
I had a manual pump one but it only lasted a couple of weeks, I have been using this one daily for close to a month now.
I am glad I spent the extra money on this one.
5 STARS

Review source: Amazon

Pros:
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

Cons:
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.

Overall:
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.

Review source: Amazon

I have a few manual pump suction clamps but they don’t compare to this one.

Pos.

Powered by commonly available AA batteries.
Easy to use.
One button control.
Suction gauge.
When the pressure falls vacuum automatically compensates.
Vacuum is automatic one powered on.
Nice hard case.
Great holding power.
Metal construction.

Negs

No repair/ maintenance parts as with others I have.

Review source: Amazon

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.

Review source: Amazon

What do you get?
A battery operated vacuum suction cup with carrying case.

How does it work?
Release the battery compartment, slide out the battery holder, install four AA batteries. Slide the holder back in and you’re ready to go.
Push the suction cup against a flat surface, press the green button and you’ll hear the vacuum pump start. There’s a suction guage that SHOULD start to move when the pump starts. IF it doesn’t, the cup is not properly sealed against the surface. Once the guage reaches the green “zone” and maintains it for 3 seconds the pump will automatically turn off. If the tool begins to lose it’s suction the pump will turn back on and attempt to restore the vacuum into the green zone.
Once you’re done. Simply push the green button a second time to turn off power to the pump. If you hit the vacuum release collar before you do this the pump will kick on and try to restore the vacuum. Not a huge deal, just push the button. But why make the pump work any longer than it has to.
You’ll notice that there are multiple filter holes in the suction cup, most of these tools only have one. I’m going to assume one goes to vacuum guage and one goes to a vacuum sensor. Just a guess. In the manual there are rudimentaty instructions on how to change the white vacuum filter. Basically “remove fitler with the tip of a screw driver. Then push the replacement filter into the bottom plate and secure it” One of those “it sounds simple enough until you have to do it” instructions
It somes with a nice cushioned carrying case to ptotect it. But doesn;t come with batteries. I took batteries that worked in my TV remotes, but they must have been close to depleted because the pump sounded like it was laboring. Put four fresh batteries in and it worked like a champ. So if you use this a lot you might want to invest in some rechargeable batteries.. The manual also suggests you remove the batteries when not in use.
It’ll grip glass, drywall, tile etc ANYTHING WITH A SMOOTH surface. You might dream about going all Mission Impossible with these and start climbing buidings. Obviously I’m not the first one to think that, since there’s a very specific warning in the manual about NOT doing so. (I still think it would be cool) Under IDEAL LAB CONDITIONS it’s rated at 440lbs. Under WORKING CONDITIONS it’s rated at half that or 220lbs. So I hope you’re not too heavy.
The benefit of this tool over others. NO pumping, there a guage to let you know the vacuum is holding and it automatically restores the vacuum should it begin to fail.
The ultimate question: Is it a good value at $150? If you just need it occasionally perhaps a PAIR of another brand for $60 will work for you. If you need this for your livelihood, it might be worth it. I’ll leave that up to you to decide.

As advertised

Review source: Amazon

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 !!!

Review source: Amazon

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.

While researching bluestone patio construction, mentioned was made of the Grabo. Naturally I had to have a closer look. It is an impressive design, well thought out, even down to the carrying case. It works extremely well. If you have a need for this kind of functionality, it is a superb tool.

Worth every cent. I have two year old Travertine Pavers that had some normal settling. I tried several things to lift them, but to no avail. This tool allows surgical removal of single tiles and easy, precise drop in as you put them back, all without damage to original pavers.

Review source: Amazon

This product works as advertised. I used it on a 24″x48″ porcelain tile floor job. It never lost suction and was a great asset for installing these large tiles while working alone. The unit was advertised as having 2 batteries and only came with one. The vendor was very prompt and proactive in getting an extra battery to me. Great product and fantastic customer service, I highly recommend both!

This little machine is very powerful. Great for carrying large sheet goods or tiles.

Review Source: ubuy.hu

The media could not be loaded. This gadgets does what the cheap $10 suction cups from the local hardware store cannot do. It lifts pavers that are not perfectly smooth. I am not sure if it lifts the kind of pavers that look like giant vitamin tablets (with lots of little holes/cracks). It does lift my 18 inch pavers from Home Depot that weight about 40 pounds each. The paver tiles are not perfectly smooth like marble. They have a texture, but they are not the large pores like on the cheaper pavers that are commonly sold in the hardware stores. Thank goodness I did not have to buy a suction gadget that requires an air compressor. This helps a lot because when I was dropping the paver tiles by hand they would disturb the flattened sand bed. Even if I dropped the paver just about 1 inch from the ground, the sand would be disturbed, and I would have pavers that were a little uneven. I would have to pull them up and fix the sand. With this gadget, I will not have to do that. I can lay the paver tiles with very good control and not disturb the level sand. I LOVE this thing.

The suction power of this thing is unbelievable…I tried all the round suction cups with the little thumb pumps…could not pick up my concrete pavers, not even close…I have very rough concrete pavers, they weigh 100lbs each and it has no problem, they are 24”x24”X2” thick solid concrete…even the ones with lots of air pocket holes in the tops it locks on and don’t let go, I will literally stick to anything remotely flat…I even hung from a sheet of plywood…no joke.

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.

I’m revising my previous review and apologize for the 1 star rating. I initially had a difficult time getting it to work properly and was frustrated with it when I wrote the review. I got it to work and I’m pleased! It’s a well made tool and I’m glad I made the purchase. Although, I wish it were a bit lighter and it wasn’t necessary to remove the battery to charge. Perhaps that’s a waterproofing issue. Minor though.

Review source: Amazon

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):

I have a bluestone patio set in stone dust that time to time needs to be reset due to settling. It is a snap to pick up a piece of bluestone with one of these. They never failed. I ordered a second one because I have a few very large bluestones that make it too hard to lift with just one.
