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

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.

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 11S

The 11S trades a map for a price: at around $120 it sits close to entry-level Wi-Fi robots, and what it gives up is not scheduling, which the remote handles, but mapping, room selection and any control from outside the house.

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 11S
Multi-floor homes or large open-plan spaces
No mapping means unpredictable coverage on large footprints. Owner reports document repeated pass-over same areas on homes over 800 sqft.
High-pile carpet and heavy pet-hair homes
eufy rates the 11S for hard floors through medium-pile carpet, and BoostIQ lifts suction when the robot detects it needs more. Above that pile depth the machine is outside its rating, and owner reports describe hair tangling in the brush.
Remote-triggered or app-managed cleaning
There is no Wi-Fi and no app, so nothing can be started, checked or changed from outside the house. The remote holds one recurring daily schedule, but there is no day-of-week selection, no room selection and no status reporting.
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 11S
  • Weekly: Brush check and hair removal on pet homes.
  • Monthly: Dust bin emptying and cliff-sensor cleaning.
  • As needed: Remote battery replacement (every 6-12 months).
  • Every 3-6 months: Filter tapping and replacement (~$8 per filter).
  • As needed: Wheel cleaning on tile or transitions.
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.
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.
