A friend is selling this system so I said would post on here for him. I dont have a clue about window cleaning so I cannot answer questions personally .
The only info I have at this moment is .it is a 2 pole system. Says internal tank creates it's own water, whatever that means. Has a35ft and 25 ft poles ,different brushes , attachments and built into a 6x4ft trailer.
I do know barely been used and in excellent condition. He has other business commitments;hence sale.
Any interest you can get in touch and I will give you his number.
