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 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 GRABO Foam Seal is a game changer! Easy to install and fits perfectly on all GRABO models.
