I ordered a replacement set of brushes for my HYYW70 patio brush cleaner on 22nd April, I have been chasing these parts since February, however when I contacted the parts department last Wednesday I was assured they had the parts and they would be delivered by Friday. They arrived Saturday, not an issue with the delivery being a day late. The Issue is that the box only contained 7 x brushes, and a full set of brushes is 9 x brushes, so I am still 2 x brushes short. Still unable to use my unit! What's going on? don't you know your own products? Surely you should know how many spare brushes make a set.
