Why are there water marks on the surface after cleaning?

Updated on 2024/02/19

1. The wiping pad might be too wet. Please wring the wiping pad out before use.
2. If the window is cleaned with a low frequency (quarterly or semi-annually), more dust will accumulate on the surface and the wiping pad will get dirty easily. Please replace or wash the wiping pad in time to achieve a better cleaning performance.
