Yes, I remember now, coming off the belt also. Best suppliers I have found is Windowcleaning stuff;Rugby your right full week and bucket has not been out of the van , so much easier and quicker not having to bend down to dip applicator .WCW stuffed up and sent belt instead of sprayer but was sorted y next day . Biggest problem is stopping it coming off belt when bending to do patio doors but will try modifying it . Have to work with less soap in mixture or it tends to leave lines when working in the sun .
