DamoH,
thanks for visiting the forum. We do not see them very often in are area,,but think about this. (self cleaning) what have you ever seen out there in any product not in hot tubs that is self cleaning... even most kitchen ovens. they have a self clean cycle, but you still need to wipe it out. What they use as there self cleaning is the floor that acts a suction to pull water through the filter. and also you still need to physically pull the filter out to clean, you still need to add chemicals to help keep the spa clean. The biggest thing i would recomend is to visit several local dealerships see what they have and if your comfortable with them, buying local is a plus , service, parts, questions.. i still believe imo to look at D1, Hot Springs, Sundance, Jacuzzi,Marquis. to just name a few. hope this helps....enjoy your spa search.
