Regarding Desjoyeux pools and other replies, I purchased a DEsjoyeux pool three seasons ago and have full experiance from the concept to completion . This is the third season of operation and I can comment as follows. The desjoyeux system is fairly simple to operate using a cotton filter bag, in normal usage I would change it three times a week . I have three bags which I pressure wash together 15 mins max, pool chemicals I use Le eclerc or Auchan products which are fine. The pool is ovaline and has roman steps at the shallow end , I would never ever contemplate using the filter steps as a route into or out of the pool . I do know of someone with a ten year old system the steps which appear more robust are the only exit and they have cracked however the filter system has worked very well for the ten years, so if you buy one get the roman steps . My pool has an overflow pipe and anyway you have a secondry pipe which can be connected and the pump will empty whatever you wish. The pump is removed after each season however you need to clean check clean and when necessary lubricate its also safe for the winter. It is true the electrics are in the filter section but mine has a safety cutout and more likely to have a problem with rain water than pool water. So all in all Im very happy. I did not want a rectangular pool with difficult acces that I have seen many times in France .
