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.

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 Robot Vacuum Auto-Empty C10

The slim 2.85in body and point-laser/infrared navigation keep the design low-profile and the price low, but independent testing found this comes without a dedicated obstacle-avoidance sensor.

Bagged auto-empty at the dock reduces manual dust disposal to roughly every 60 days, but the robot itself remains vacuum-only with no mopping option.

Roborock S4 Max

No object recognition: with LiDAR, cliff sensors and a bumper but no camera, the S4 Max maps a room accurately and still drives into the cords, socks and pet messes that camera-equipped models identify and route around.

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 Robot Vacuum Auto-Empty C10
Homes wanting mopping capability
This model is vacuum-only; it has no mopping hardware.
Homes with frequent floor clutter or loose cables
Independent testing found no dedicated obstacle-avoidance sensor, so the robot does not detect or route around small objects.
Households with thick carpet, dark stairs, or thin furniture legs
Reviewer reports cited difficulty in these specific conditions.
Roborock S4 Max
Owners wanting hands-off dust management
The S4 Max charges on a plain floor-standing base with no auto-empty function. Emptying the 0.46 L bin by hand every one to two runs is part of using it, and no auto-empty retrofit exists for this model.
Large open-plan homes over 2,500 sqft
Single charge supports 110–130 minutes runtime on carpet; large floor plans require multi-session scheduling or manual recharge.
Homes prioritizing quiet operation
Flagship models run 65–68 dB; the S4 Max runs 68–70 dB in standard mode. Noticeable in sound-sensitive environments; use eco mode (quieter, slower) for off-peak times.
High-pile carpet with heavy pet debris load
Suction is solid for daily maintenance but trails S8-series flagships. Owners with thick matted carpet or weekly pet shedding may need stronger brush design.

What stays your job

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

eufy Robot Vacuum Auto-Empty C10
  • Dust bag: Replace the dock’s 3L disposable bag on a roughly 60-day cadence.
  • Pre-run tidy: Clear cords, socks, and small objects before each run, since independent testing found no dedicated obstacle-avoidance sensor.
  • Dock placement: Requires a clear, hard, even surface for reliable docking, per research on this model.
  • Setup: Set no-go zones and multi-floor maps once in the eufy Clean app.
Roborock S4 Max
  • After every 1-2 uses: Empty the 0.46 L onboard dustbin into the trash. The S4 Max is bagless and has no auto-empty dock, so there is no bag consumable to buy.
  • Monthly: Inspect main brush for bristle loss and embedded hair; clean wheel and side brush; rinse the bin and check its seal.
  • Every 6-8 months: Replace main brush (~$14–18) if bristles show notching or loss.
  • Annually: Replace filter (~$8–14).
  • Every 12-18 months: Replace side brush (~$8–12) depending on pet presence and usage.
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.
