Quzhou Zhifeng takes 4.98% stake in pool-robot maker Siaotuo

What's the deal? Quzhou Zhifeng has made a strategic investment in Shenzhen Siaotuo Technology, acquiring roughly 4.98% of the underwater intelligent equipment maker. The deal was announced in July 2026.

What's the endgame? Siaotuo develops underwater smart hardware, focusing on robotics research, sales, and electronic products. Its patents span underwater robot drive structures, cleaning robot designs, and waterproof sealing technology.

Why now? Quzhou Dongfeng, investing through platform Quzhou Zhifeng, is targeting "hard tech" sectors including semiconductors, new energy, high-end equipment, and intelligent robotics. It has framed the small stake as limited in financial impact but strategically directional.

Siaotuo has built its business on price. Over the past two years it cut pool robots with roughly $1,000-level performance to about $400 and spent almost nothing on marketing, pushing global revenue past $100 million.

The signal: Service robots keep expanding into home cleaning niches — vacuum robots, lawn mowers, and pool cleaners. With underwater robotics still a blue-ocean market and targets scarce, industrial capital is placing small, direction-setting bets to stake out position early.
