Yeah, that was just a nitpick. Sorry, this looks like a scam otherwise; I should have been clearer about that.

Aside from getting your clients sci-fi rocks off, why would you even go with humanoid legs? Some basic wheel-leg combination that can climb stairs would make way more sense in an indoor context. And that's not even getting into the non-robot maid ways to automatically water plants and vacuum, which are the two cited tasks it can do.
