We return from a trip to Japan where my wife and I both used the hotel installed personal hygiene system with both front and rear spray. We both fell in love with the process. I researched the options and chose the Swash 1400 based on features, reviews, and cost. Installation was easy following the video instructions and included manual. Took about 15 minutes for this 77 year old. Works like a charm. Easy sequence modifications, position, temperature, pressure, oscillation, etc. Bought one and after installation and first few uses order the second. Very happy user.
