Perfect Replacement Roller Mop for Eufy Robot Vacuum
This replacement roller mop fits perfectly and works just like the original. Installation was quick and easy, and the quality feels durable and well-made.
It does an excellent job picking up dust and light debris while providing consistent floor cleaning performance. The roller is washable, easy to maintain, and holds up well after multiple cleaning cycles.
I appreciate that it restores the robot’s cleaning effectiveness without any compatibility issues. If you own a compatible Eufy model and need a replacement, this is a reliable option that keeps your robot performing at its best.
Highly recommended for maintaining optimal cleaning results.

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.
