Works great on smooth granite or concrete
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.
The S1 has been a fantastic addition to my GRABO. So much easier and comfortable to lift heavy items now.

I bought an extra GRABO battery for my Pro, and it's been fantastic. The original battery is great, but having a spare means I dont have to wait for it to recharge. Switching between batteries is super easy, and the extra one doesn’t take up much space in my tool bag. Highly recommend grabbing an extra if you use your GRABO a lot.
