Good afternoon, regarding your problem that the MOVA V50 Ultra Complete does not use the detergent: Since the detergent is concentrated, about 1-2 ml of cleaning liquid is used with each use.
You can shake the dirty water tank and observe if foam forms to see if the device has used detergent when cleaning the mobs.
If you need further assistance, please provide your ticket number or contact us via Email:
