In case you don’t know gvs
Go on YouTube the have some videos showing the 51 mm cyclonic adaptation
They take readings of the airflow before and after modifying.
I nearly went for the cyclonic small machine
but they were out of stock.
There’s some good deals at present on the Aom
If I had £2000 to invest I would go for the GVS predator again watch their videos,
I’m not sure if I’m gonna like gutter cleaning 🤔
So been frugal 😁
Good luck with what you do mate
