01 Classification

What each one does on its own.

The Autonomy Ladder is the same five rungs for every robot on the site. A rung describes the conditions a robot handles without you, not how good it is.

Any task, any setting

Finishes familiar jobs on its own

02 Assessment

Where they actually differ.

The Robovations Score is nine inputs across three pillars, each weighted as shown and each scored so that more is better. A robot can lead on one and trail on another, which is the point of showing them apart. Cost of ownership and data handling are reported on each robot's own page and are never averaged into the score.

03 Measured against the class

How far apart is a long way?

A number only means something next to the spread it sits in. Each track below is the real range across every classified robot in the class, with the median marked.

04 Ownership

What the numbers leave out.

The trade-off

What each design gives up to be good at what it is good at.

LOVOT 3.0

LOVOT self-navigates and self-charges without direction, but its operating cycle between charges is short: approximately 30-45 minutes of activity per 15-30 minutes of charging.

The unit price is a single upfront cost, but GROOVE X’s own documentation states an additional monthly software fee is necessary for the device to operate day to day.

Sony Aibo ERS-1000

You are buying emotional attachment to a proprietary closed system. Sony controls the subscription and the service behind it, and nothing documented lets an owner keep full function locally if either ends. Sony has never closed an aibo cloud service; the precedent that does exist is the end of official repair support for the 1999 to 2006 line, in 2014.

Eight years of ownership stories prove Aibo’s reliability and engagement value. But the lack of practical task capability means the robot does not reduce household workload, it adds one more device to maintain and charge.

Who each one is wrong for

Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.

LOVOT 3.0
Buyers outside Japan, mainland China, or GROOVE X's listed regions
No official US, or broader, retail channel was found; importing through a third-party proxy service adds substantial cost.
Anyone wanting a one-time purchase with no recurring cost
GROOVE X's own pricing documentation states a monthly software-usage fee is necessary for the device to function day to day, on top of the unit price.
Buyers wanting a task-performing robot
The manufacturer explicitly does not position LOVOT as automating household chores.
Sony Aibo ERS-1000
Owners expecting autonomous home task capability
Aibo is a companion, not a task robot. It has no gripper, and it does not clean, carry or fetch. The one exception is aibo Patrol, a named Sony feature on the premium plan: Aibo walks a scheduled route through the home, looks for registered people and reports back through the app. Sony offers it as entertainment rather than as a security system, and it does not reduce any household workload.
Buyers uncomfortable with mandatory cloud subscriptions
Full behavioral learning and app interaction require $13/month cloud subscription. Offline mode is severely limited; feature gating is aggressive.
Owners with poor home network or privacy concerns
Aibo carries two cameras, the nose camera and a dedicated SLAM camera, maps the rooms it moves through, and enrolls up to 100 faces to tell people apart. It needs Wi-Fi for behavioral updates and interaction syncing, behavior data syncs to Sony's service, and no local-only operation mode is documented.

What stays your job

The upkeep ownership hands back to you, whatever the autonomy level says.

LOVOT 3.0
  • Monthly: Keep the software fee current, reported at approximately 9,900-19,800 yen across GROOVE X’s service tiers; GROOVE X states it is required for daily operation.
  • Monthly: Wipe its cameras and touch-covered body surfaces with a dry cloth.
  • As needed: Maintain its fabric covering and clothing; GROOVE X sells interchangeable outfits as accessories.
  • As needed: Keep the Nest (model LN110) powered and unobstructed; LOVOT docks itself for a 15-30 minute recharge after every 30-45 minutes of activity.
  • As needed: Maintain the Wi-Fi connection; software updates arrive from GROOVE X’s cloud as part of the subscription.
Sony Aibo ERS-1000
  • Daily: Charging on the station; 2-3 hour runtime per charge.
  • Weekly: Clean the eye lenses and the nose and SLAM camera windows to remove dust and fingerprints; light surface wipe-down.
  • Monthly: Subscription payment verification ($13/month for cloud features).
  • Every 3-6 months: Joint lubrication check if movement becomes stiff or grinding appears.
  • As needed: Sony repair service for actuator wear. Sony publishes no price list for repairs.
05 Evidence

How much each of these is standing on.

Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.
