Go

I'v heard they wont work right, theres been a lot of reviews and like a roomba they go in a random crazy pattern. So one area may get clean everytime, some spots will never be cleaned at all. plus there is no sand sensor or boundary sensor, so if it hits the sandbed, youre entire front will get scratched. Plus even me complaining about no maint time can spend 2 minutes with a magfloat lol. I think they're expected to be close to $200.
