You should empty and rinse the dirty water tank every 1-3 cleaning sessions. If you skip this step, the tank can start to smell bad and become unhygienic for future mopping.Do all mopping robots have a dirty water tank?

No. Many simpler or older models only have a single water tank that drips onto a mop pad without rinsing it. These are cheaper but less effective at deep cleaning because the mop gets progressively dirtier with each pass.
