Wasnt going to bother with a gutter VAC as I hate gutter wok but I have other needs to buy a wet VAC so to kill two birds with one stone was going to get a nisflik VAC as for a budget bit of kit seems to tick all the boxes.
Questions are
   Which model
   Where do I get extra hose (51mm and any adaptor) 
   Cheap poles as for low level domestic.
Thanks for any help.
Craig.
