Hi, 

I purchased the robot last year and have been using it daily. However, I am unable to use the mopping function to its maximum. I cannot find the multi-surface floor cleaning agent anywhere online, and I can only use plain water to mop the floor. This defeats the purpose of its function because I have to mop the floor myself. 

When is the cleaning agent going to come out? I feel cheated because I have paid for all the functions and capabilities of this robot but only to use the basic one.
