True, though very few (this says "over 1,500"[1]). And from everything I've seen, Spot appears to be a very expensive solution in search of a problem.

They also have Handle, a slow moving robot on wheels with an arm for moving boxes. No idea how many have been sold, but it seems to be even less than Spot.
