Our take

aibo is still the most lifelike walking robot dog sold to consumers: 22 axes of motion, face recognition, home mapping, and a personality that develops through Sony's cloud.

Our take in full, what's good, what's not

aibo is still the most lifelike walking robot dog sold to consumers: 22 axes of motion, face recognition, home mapping, and a personality that develops through Sony's cloud. Sony announced in June 2026 that it is ending Japanese sales once stock runs out; U.S. sales and support continue for now, so this is a last-call purchase. Budget for the cloud plan ($300/year after the included three years), a two-hour battery, and the fact that it is not sold in Illinois or Baltimore because of biometric-privacy laws.

Good
  • Walks, plays, and recognizes people better than anything else on this list
  • Sony support and parts still available in the U.S.
  • Includes three years of the required cloud plan
Not
  • Roughly $3,000, then $300/year
  • Discontinued in Japan; long-term support risk
  • Two-hour battery; indoor flat floors only

Who it's for

An adult enthusiast with the budget who wants a walking dog and accepts end-of-life risk.

Who it's not for

  • Discontinued in Japan; long-term support risk
  • Two-hour battery; indoor flat floors only

How we know this, and sources

Specs and prices come from the manufacturer's own pages and press releases, checked on September 5, 2026; owner-reported limitations come from published reviews and caregiver forums. We have not yet tested this unit hands-on — what that means. Price confidence: medium. Confirm on the manufacturer's site before buying.

Price note: CONFLICTING: Sony's last published US price was $2,899.99 (Feb 2024 Espresso Edition press release; original 2018 launch price). 2026 sources report $3,199.99 (HomeBotRadar, Aug 2026) and AFP wire (June 26, 2026) says aibo 'retails for more than $3,000' in the US — consistent with Sony's 2025 US tariff-driven price increases. Sony's US store page could not be fetched; verify on us.aibo.com/store before publishing. Price includes 3-year AI Cloud Plan; renewal $300/year after.
