I have been looking at the envirodri website wondering whether to buy the white standard brush or the black and white intermediate stiff brush. I already have the machine with the gold brushes and don't want to buy more than one more set of brushes.
The site says that the white ones are the most versatile of the brushes but given that I already have the gold ones which came with the machine I thought that the black and white may be best for me given that I am mainly concerned about tackling heavily soiled carpets.
Any observations appreciated.
