Well, I AM a mod (heh, heh) and I'm not looking to close it yet. If Ben asks me to I will, but I think that robotic cleaners are SUCH expensive items that these serious issues with one brand are important.

I'm thinking if I don't get a positive resolution that this may be something to suggest for the Hall of Shame.

Meanwhile, I'm finding the Blue Diamond works quite well, and is very thorough despite its eccentricities.
