The ECOVACS manufacturer obviously considers his own and is doing well. I tried it thoroughly and I have to say it is a great product.
I then used 2 more specific liquids for glass cleaning:
HALO Streakfree - it's fine
Windex - it's fine
I tried spraying water with a 20% vinegar and gave me good results but some halos.
Other tests with only water. Positive result only in the absence of obvious traces of dirt.
In conclusion, I think a good brand detergent gives excellent results, but I have a slight preference for the original ECOVACS product.
