Not good, poor quality from Eufy products
I bought this as a last try to fix my unit. I wanted to share my experience with the Eufy S1 Pro after owning two units. Unfortunately, both units had serious issues. The first one developed multiple problems within less than a year: Dirty water tank issues Mop roller lifting motor malfunction Loud and abnormal noise during dust collection Eventually stopped working completely Despite that, I decided to give it another try and purchased a second unit, planning to reuse parts from the first one if needed. However, the second unit failed even faster. After around 2 months, it stopped performing dust suction from the robot to the base station. At this point, I cannot recommend this product. The reliability has been very poor in my experience, especially considering the price. On a positive note, customer support has been responsive and helpful, but unfortunately, the product quality itself did not meet expectations.
