After setting up the new Z60, I went to fill up the mop water tank. It's considerably smaller than the one on my previous robot from another brand, but that robot had spinning mop heads versus the roller brush of this vacuum, so potentially it's a lot more efficient. I'll post again after I've gone through a mopping run to see how much water is used. You can also see a comparison picture of the MOVA V50 Ultra (in white), and the Z60 (in black). They're actually very similar in overall size for both the vacuums and their dock's. #sponsored, #GetYourZ60, #Z60URC
