i did have a little trouble with the flocked brush, but i think that was down to me using the sl-x for the first time, on 2 and 3 ups, the pole is light and the brush to, i was used to the xtel and harris with sill brush, so i put it don to the lightness of the brush and working at height, i had trouble scrubbing with the flocked brush, or am i using the wrong one for that height for scrubbing power,
