If my Ecovacs unit died today I would order another one right away!
I had an X1 and had repaired a wheel then the freshwater solenoid went so I decided to upgrade to the X2. These robots keep 3200 sq ft impeccably clean. I never have to vacuum or mop. I decided to use the X1 every other day to vac and the x2 to vac and mop the other days to extend its life. They work tirelessly.
