Replaced my Ray Vac (2nd in 22 years) with Polaris 360 and am VERY HAPPY with it. Picks up a lot more than Ray and the bag does not lose anything when pulling it out of the water. Only thing was making an adapter for Polaris fitting (1.5 " to 3/4" wall fitting). Took a 1.5" female PVC fitting and placed a cap in it. Drilled a 3/4" hole in cap and cemented 3/4" male adapter to cap. Fits in threaded wall return perfectly and cost $3.00 for parts at Lowes. Plugged it in and runs great. Less PSI than Ray also.
