Hi Chicken Man,
We have used the extreme brush's over the last couple of month, very impressed.
On all our SL brush's we have 6mm fine fan jets sourced form cleantech.
Question is, Do you have any pics of the extreme brush with fans fitted?
What size fans are they?
Sourced from where?
Did not think the extreme brush was suitable for fan fitting, not enough stock body on the brush.
Any tips would be very helpful
