I was at iRobot for holiday season 2003; 1st gen Roomba was out, MANY of the returns piled up along the hallways of HQ.
One day the "director of sales"? walked into the standup meeting like Vince McMahon into the arena and slammed down this robot onto the coffee table that was a pitch-perfect copy of the Roomba, except it was tea green and had more colorful LEDs and sounds. "F this and F that" like we had any ability to stop that from happening. I did the teardown and it was a near-perfect mechanical copy like somebody walked the molds across the street. The PCB was different where they chose cheaper connectors. It was way prettier looking IMO. What they couldn't copy was the logic; the SW/uC was handled through a different chain so unless you literally stole a pile of programmed parts, you'd be on your own. The Roomba development team consoled themselves that the performance of floor coverage of this knock-off was worse than the original...but to be frank, both were only useful under limited circumstances that I found nobody I knew had. I'd have better luck with an old sweep-broom.
As an intern, those returns piling up were so they wouldn't get resold elsewhere or scavenged. And there were a LOT of returns; its a complicated design with a LOT of cables and connectors and some marginal components going out of the expected tolerances. One of my jobs was to strip out the batteries, lay these robots out in the back parking lot, and using a pointed steel rod, 'spear-fish' them to render them unusable. To make my work quick I'd aim for the 'brain' - the middle where the case was thin and I'd bust through the microcontroller part of the main PCB. Aim, 'crunch', make sure I 'killed' it, and then fling it into the dumpster. Nearly 20 years on, I fondly remember thinking 'I can't believe I get paid to do this!'
