Hi all, I'm looking at purchasing a Pentair Warrior SE, as it seems to be the go to cleaner around here. I've seen posts about is buying the caddy worth it, but I haven't seen anything about the build quality of the caddys, and I've really only seen one or two pictures of it. My question is, is the caddy just a cheap pieces of plastic that will break wheels off unless you only roll it around flat concrete, or will it handle pebble walk ways, going up a over ledges, etc, and does anyone have a few pictures they could share? If it's going to break easily or not be very mobile, I'd rather buy a pneumatic wheeled hand truck and build something to hold the robot, controller, cord, etc. Thanks.
