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 12x24 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.
This tool worked great, better than expected! On smooth to semi-smooth surfaces it has long-lasting holding power even after the pump is turned off. We used it on an acid-etched concrete panel and it carried the 120-lb panel with ease with the pump running continuously (which should be expected on this type of surface). They're fairly light weight and ergonomic, which beats the heck out of air cups with hoses and compressors attached.
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.
Sparky –
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.
