A window-cleaning robot company raised about $7 million—but is the real opportunity selling robots?

Physical AI isn't as far away as you think. The Startup Ideas Podcast recently shared a case: Ozmo, a company that turned window cleaning into a subscription service. Building owners don't buy equipment; they pay for “clean windows.” Ozmo handles deploying and operating the robots. According to the podcast host's estimate, the company recently raised about $6 million to $7 million.

This model offers three entry points:

1. Start a company like this (the hardest).
2. Buy a few robots and rent them to people who need them.
3. Sell robots: there's a big opportunity for sales and marketing people.

Options 2 and 3 don't require a PhD.

Many people think Physical AI is a distant future like “The Jetsons.” But the podcast host believes we're almost there, and you'll see more businesses like this. He quoted his friend Brian Norgard: “The best way to sell software is to sell hardware.”

In other words, whether you build robots, rent robots, or sell robots, there's a place for you. The window in this video is proof.

One commenter said windows are an easy case: the owner pays, and there's no one in the building. But home robots are a completely different story: adult children pay, but Mom has to live with the robot, and she has to accept it. Trust comes before the pricing model.

Others felt option 2 isn't easy either: “Building robots is hard in itself.”

Another commenter wondered: robots-as-a-service works for windows, but would family members want to own that robot at home?

There's no standard answer to this question. But at least the window-cleaning robot has already climbed onto the glass. Physical AI has already begun.
