Yes, i own the JandR washable, and i love it.
i just douse it in whatever i'm cleaning it with wothout any worries and then re-put my hose cover from samn on it and bam, i have a sexy Hose.
It draws MUCh better than the Nammor as well. In the Nammor, the acrylic pieces restrict airflow. And the width of the inside of the hose where the smoke is pulled form is not really 3/4" , it's less, because the WHOLE hose (including the outer wrapping) is 3/4" exactly.
