I have a univalve on all my poles but on my 25 SLX  it only works if pole is extended. when collapsed it doesn't work which can be frustrating. Does anyone know why this is happening?

That would imply its catching on the interior of a joint, try moving to top section up a foot or so to see if this free's it, if it does shorten the length of hose from the univalve to the brush.
