Correction: a LogiTech PC mouse pointer works on the black knit fabric defeating detection by phototransistor tested. Maybe that mouse laser tech could make workable cliff sensors with a parallax method. Some Asian robot had a mouse in the bottom for navigation. Laser diodes require a special driver IC for their positive feedback qualities. At least it won't need a scroll wheel.

There exists a solution path there yes. The optical mouse on bottom of 980 is what distinguishes between hard floor and carpet for example by reading the raw signal in (analog). The IC in mice for example dumbs down the signal to just an XY delta. So need the raw signal

Of course, different signal processing. So an extra receiver on the carpet detector, with an angled focus on the laser beam for parallax might serve as a cliff detector at minimal cost, assuming carpet detection supplied. That feature is appearing on several brands now. Since carpet would be in range of the cliff detector maybe a single receiver could do both if just mounted at an angle with proper focus. I wonder if that carpet detector is fooled by any of the problem hard floors reported defeating the ordinary cliff sensors. Of course that is safe to turn off in a menu option.
Maybe the carpet is detected by texture signal variation while the bot moves, related to mouse movement sensing.

A TV remote IR receiver works on the problem black knit cloth. See hacking forum post. Maybe cheaper than laser tech. I also question whether that is needed to distinguish carpets from hard floors, with alternatives such as changes in brush and drive wheel drag affecting motor loads monitored.

Maybe Roomba needs laser tech for floor type detection because the innovative 800-900 series brush roller design does not show any drag effects on carpet useful like the brushes on other brands, if that is what they use -- methods not published.

Currently doing a funding round of investment. So will release information when the round closes

May use one of those two as a boost to a traditional round (not at liberty to confirm or deny at this stage), but will let this site know of that first when it comes around.
