I have an Aqualtis AQXXF 149 PI and I am very pleased with it. It's a lot quieter than my old Hotpoint Aquarius. I like the flexibilty - being able to vary the temperature and spin speed etc. I am pleased with the washing results although I was disappointed that a 13 tog single duvet was a tight squeeze to fit in so didn't wash well when it should be able to wash a double. I have a bad habit of starting a wash then realising I've forgotten to put something in - with the Aqualtis you can press pause and the door will unlock at any stage. It can do this because the drum is tilted backwards so it doesn't matter if the drum has filled with water. Also the drum is higher than on standard washers which makes it more comfortable to load and unload. Another good feature that I like on mine is that it has a timer which tells you how long the cycle has left to run.
I would definitely recommend the Aqualtis because I find it more economical to run and because of the large drum it has cut down the amount of loads I need to do each week. It also looks really nice too!
