They are almost there I’d say, almost to the point they need to be where someone could be happy with their product. Let me give the analogy of a printer. If yours can run for months without getting jammed that’s good but changing cartridges is a hassle. If it runs for months without running out of toner, that’s hassle free. Not going to be a cheap printer, but hassle-free. ChillX has made scooping convenient where others have failed but, the AutoEgg cleaning, and changing the waste bag and replacing the litter isn’t streamlined enough to consider this the hassle-free technology. They need need to enlarge the waste drawer and automate those functions, in 10 years it will be hassle-free I predict.
