ABOUT TOP SUN POWER

Ten years making
outdoor robots that actually work

Top Sun Power is an outdoor robotics company founded in 2015, headquartered in Suzhou, China. Our focus is simple: build autonomous machines that work reliably outside — starting with the world's most common outdoor chore.

Our engineering team spans mechanical design, sensor fusion, computer vision and GNSS positioning. We were one of the first companies to ship a true wire-free robotic mower, and we're now on our fourth-generation platform.

Over 180,000 TurfBot robots are mowing lawns in 28 countries today. Every model carries a 5-year warranty, global service and monthly OTA software updates.

OUR PHILOSOPHY

What We Care About

🤖

Reliable Outside

An outdoor robot isn't useful unless it's as reliable as a fridge. Zero tolerance for "sometimes it works".

🧰

Hardware First

We don't cut corners on steel, sealing, motors. A robot that lives in the rain deserves to be built like it.

📡

Software Forever

Every TurfBot gets monthly OTA updates — your robot keeps getting smarter years after you bought it.

🌍

Global Service

We're only as good as our support network. 28 countries, 240+ authorized service partners.
