I have three Nat, Sounds excessive I know, I have a 48 ft and two @ 36 ft. One 36 and the 48 are set up as power washer poles and the other is used as a support pole and for use with the gutter spike camera etc.
They are not the lightest of poles but they do need to have a bit of weight as this makes the both strong ,rigid and able to do some very tough jobs like using the spike to remove turf from gutters.
In my opinion they are fantastic for a range of jobs from cladding cleaning to use with the Omnivac.
One of my better investments. I have had two of my poles over 18 mths they get used most days and still look new.
Hope that helps
