I found that kind of funny too. Beats me. :) This is my first one with a self-empty base and I'm surprised how much I like it. I don't think the pre-mapping self-empty units would have worked very well for me because they would usually get stuck, but I've been quite impressed at how well the j7 manages to avoid that. It does have an annoying quirk that it won't run if it's too dark, so I have to schedule it a little carefully or leave the lights on and schedule them to turn off. But I'm really happy with it overall.
