They bleed money and are not revenue positive yet. And all those re-acquisitions indicate that none of their parent company could provide a nurturing environment to enable the company to make profit.
My two cents. If not military use or a very expensive niche use, e.g. for emergency services, then those things will have a pretty hard time to enter the mass-consumer market.
What will probably happen is that a Chinese company will be able to produce a 80% version of those machines for less than 1k. This is when those things will become interesting to consumers for whatever purpose those things can be used.
As long as the SPOT robot costs over 70k, nobody will even consider buying it.
