Choose the Ecovacs Half Year Accessories Kit for X11 series if you use a compatible X11 series robot vacuum and want a longer maintenance refresh so you have spare parts ready before suction or mopping performance drops. It is most useful for customers who run the robot regularly and do not want to wait until brushes, filters, or mop parts are already worn out.
This kit is for maintenance, not for upgrading the robot to a different model. If your DEEBOT is cleaning less evenly, leaving more dust behind, or the app/cleaning routine reminds you to change consumable parts, this type of accessory kit is the right place to start.
