Composed from the two directory records, so it updates when they do.
Our verdict
Same maker, same silicone craft and the same Aria character, in two very different packages. The F-Series Aria outscores Echo on every dimension of our index, most of all reality (75 vs 20), but Realbotix stopped listing it in October 2026; it was last listed from $125,000 plus $199.99 a month. Echo is what Realbotix sells now: the Aria persona on an $11,950 Tabletop or a $59,950 Full Body, reserved today for delivery in the second half of 2027. Neither walks.
- Pick Aria if
- Pick the F-Series Aria only if Realbotix confirms it will still build one and you want its 17-motor face and wheeled base at a six-figure price.
- Pick Echo if
- Pick Echo if you want the Aria character at a five-figure price and are comfortable paying toward a robot that ships in 2027 at the earliest.
