Our verdict
Both are on preorder with five-figure entry prices: the Echo Tabletop at $11,950 and the U1 Lite at about $17,650. The U1 is the more ambitious machine, with a full-body Pro trim that walks on flat indoor floors, and it outscores Echo on every dimension of our index. Echo stands still, but it speaks 100+ languages and is sold for delivery in the US, while the U1 launched in Mandarin through JD.com. Echo's deliveries aren't due until the second half of 2027.
- Pick Echo if
- Pick Echo if you're in the US, want a silicone companion from a maker that has shipped robots before, and don't need it to move.
- Pick UBTech U1 if
- Pick the U1 if you want a lifelike face on a body that walks and can work with a Mandarin-first launch.
