I have one of these.

because I don't have a wardrobe, just open hanging (designed for a walk-in dressing room)
It's only rated at 8kg though, so it's only for shirts.
Also, you have to be very gently pulling it down, and control its descent or it will crash at the bottom and the mountings will come away. There's a lot of force being transmitted through crappy plastic bits.
Looking at what you're doing it seems you'll get away with the pocket door. You should be very careful that you can still fit the washing machine in once the pocket door mech is taking up some width. I didn't find it difficult to fit but they are quite expensive.
