W-robot X40 Enters US Market: Challenges Mill and Lomi

Traditional backyard compost tumbler

In 2026, American households’ food waste processing market welcomes a new player.

The W-robot X40 from Jiangsu, China, officially enters the US market, bringing 105 patents and a “fully automatic closed-loop” promise, directly challenging Mill and Lomi.

This isn’t a story of a Chinese brand “incidentally selling to America.” W-robot was designed from the ground up for North American single-family homes — those 40 million American households with yards, gardens, and composting habits.
