DO NOT buy a GTC steam mop!
The handle broke when I assembled it. 
I exchanged it at HEB & the working one barely shoots any steam at all.
GTC brand products are sold only at HEB grocery stores.
I still haven't decided whether to go for a Haan like Vacuumfreeke's or a H2O steam mop X5.
Since I've never tried any steam mop, I need a bit more research on the H2O mop X5 before I buy it.
