I have one of those. If you unscrew the spray lance the thread takes a standard, garden tap, Hozelock connector. Fit two female connectors on a piece of hose about 6 ins long.
Click on of them onto the garden tap connector you have just fitted. You can then fit a reducer connector into the other one. [Wintecs do them] This will fit into your microbore pole hose. dead easy, and a great piece of kit. Dai
