Sorry but was the auto empty not patented? Unlike software I thought you patented every small increment in the hardware world. If patented and still copied, was it their patent was not tight and allowed loopholes of modifications?
- MBCook 3y agoUnlike the brush thing I’ve never seen it discussed in regards to patents. I think someone else had made one before them, maybe a few. But they didn’t work well. They made the first one that actually worked well. Because of that I’m not sure how much they would be able to patent. Honestly it’s effectively a vacuum to vacuum out your vacuum. Maybe it was just considered obvious by the patent office. I do know that theirs could tell when it was full. Which is a nice feature. The Roborock docks, at least as of my model which is maybe two years old, couldn’t do that. Whether that’s due to design or just cost savings I have no idea.
