Oh dear again exceed Inovation brought this out about 7 years ago , catch up Herman . We are removing dirt from windows using a brush we don’t need heavy engineering for that it only weighs 200 grams
It's not the weight of what you have on the pole .
But the force you put on it especially having scrubber or doodlebug on the pole.
Where some people put a fair bit of force on it.
So in that case it would be necessary to have heavier duty angle adapter.
Most angle adapters are particularly weak when it comes to using it with force side ways.
