Well, do you want an eye-safe laser? And want to operate outdoors? The Neato is about 5m indoors, 2m outdoors with a sun shade. That reflects a lot of effort

The Neato is about 5m indoors, 2m outdoors with a sun shade. That reflects a lot of effort fighting the "sun blindness" problem that having a powerful IR source shining in through your picture window causes for the vacuum cleaner.
Practically, you want to modulate the laser so that you can filter for an AC signal.

The deeper IR you can go and the narrower your filters on the receiving side the better. Other issue I had dealing with an IR comm link 30 years ago was it sucks compared to RF because your sensor aperture is very small compared to an antenna. And as you mentioned the the ground floor is much higher with IR than RF.
