Really don't see what the issue is with the cleaning i have had my Xtreme #2 for 8 weeks now and have cleaned maybe twice a week .
When i get home i quickly dismantle pole give each section a quick rinse down with water then leave to dry overnight then reassemble in the morning takes less than 5 minutes all in .
It doesn't matter whether you buy an Xtreme or SLX if you're more than happy to trash a brand new pole without cleaning it more so this time of year with crappy wet weather and more chance of getting dirt/grit inside pole then it really wont make any difference to the wear rate long term only your wallet will be hardest hit .
i couldnt be bothered to do that every night after a days work.i extend the sections and flush with water usually once a week and take it apart maybe once a month and do what you do.
i clean the pole hose a lot though when putting the pole in the van between jobs.obviously when you can feel grit in the pole.take it apart and clean it.sand is the worst!
im happy to buy a new main pole every 2 years.
i dont treat it with kid gloves.it gets used for nearly all work in its lifetime.(f/s/g,conny roofs,etc)as well as most window cleaning.
my xtreme mk 2 is now a back up pole
what will a main pole earn you in 2 years?80k-90k?
