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.

V
Generalized
Any task, any setting
IV
Environmental
Handles new obstacles without help
III
Conditional
Finishes familiar jobs on its own
II
Assisted
Runs preset routines, needs rescue

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.

Eufy RoboVac 30C

Boundary strips are the only containment method, no map, no virtual walls, no app-based room selection. Flexibility is the cost.

BoostIQ buys carpet performance with half the runtime: eufy publishes about 100 minutes on hard floors in standard mode, about 50 minutes in BoostIQ mode on carpet and about 40 minutes at maximum suction on medium-pile carpet.

Shark ION Robot 750

App scheduling and voice control arrived early for the price tier, but navigation is sensor-reactive, so coverage is approximate and cleaning order is not controllable.

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.

Eufy RoboVac 30C
Homes larger than 2,000 sqft needing single-session coverage
100-minute runtime cannot cover sprawling layouts in one pass; return-to-dock requires manual restart.
Multi-floor homes or frequent room reconfiguration
No map persistence between locations; boundary strips must be repositioned for each new space.
Owners wanting autonomous room-to-room transitions
Lacks mapping; cannot select target rooms or avoid specific areas without physical boundary strips.
Households with thick or high-pile carpet
Standard suction is 1,500 Pa, and BoostIQ 2nd generation raises it automatically within 1.5 seconds when the robot needs more. The cost is endurance: eufy publishes about 100 minutes on hard floors in standard mode, about 50 minutes in BoostIQ mode on carpet and about 40 minutes at maximum suction on medium-pile carpet. Owner reports document reduced pickup on plush surfaces.
Homes with heavy pet shedding on carpet
eufy describes a 3-point cleaning system with a rolling brush and a squeegee blade, and notes it sweeps up trodden-down hair; BoostIQ lifts suction on rugs. Owner forums still report visible hair clumping on carpet in heavy-shedding homes.
Shark ION Robot 750
Homes needing room-targeted or zoned cleaning
With no mapping, the 750 cannot clean specific rooms or honor virtual zones; physical BotBoundary strips are the only containment tool.
Users wanting multi-floor persistence without manual intervention
The 750 stores no map on any floor, so there is nothing to save, switch or resume. Each run is an independent random pass over whatever the robot reaches.
Owners prioritizing hands-off maintenance
No self-emptying dock; manual bin emptying required every 2-3 sessions in typical homes.
Homes with thick or high-pile carpet and heavy pet shedding
Shark publishes no suction rating for the ION 750, so there is no manufacturer figure to compare it against other machines on. Owner reports document clumping on deep carpet with pet hair.
Owners wanting the latest firmware support
Shark has moved focus to newer ION models; older firmware updates are infrequent.

What stays your job

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

Eufy RoboVac 30C
  • Weekly: Empty dust bin; check the rolling brush for hair tangles.
  • Monthly: Wipe sensors and brush contact points with a dry cloth.
  • Every 3-6 months: Inspect dock for dust accumulation; wipe charging contacts.
  • As needed: Replace a length of boundary strip when the adhesive stops holding; clear fiber wraps from the wheel undercarriage; replace the rolling brush or squeegee blade when worn. eufy publishes no replacement interval or price for either part.
Shark ION Robot 750
  • Weekly: Empty dust bin; check primary brush for hair tangles.
  • Monthly: Wipe sensor windows with a soft cloth; clean wheel undercarriage.
  • Every 3-6 months: Inspect charging dock contacts and clean with dry cloth.
  • Annually: Replace primary brush (~$30); replace secondary side brush (~$15).
  • As needed: Reposition BotBoundary strips when the furniture layout changes; there is no map to update.

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