After adsorption test, we found out that the filament of original gutter brush 75mm is too large and there’s large space between filaments, resulting in poor adsorption capacity.

In response to this situation, AOQUN gutter brush 75mm can be shipped after process inspection, finished product inspection and the delivery inspection. AOQUN filament has uniform density, no filament lost, so it greatly enhances the adsorption capacity of the gutter brush 75mm.

The quality of Aoqun gutter brush 75mm is excellent and acknowledged by the new and old customers.
