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.

Lefant M5 Pro Robot Vacuum and Mop

The all-in-one dock reduces manual dust and mop-wash upkeep to a roughly 120-day cadence, but the camera-less sensor array trades some object-detection accuracy for that design.

Combined vacuum-and-mop cleaning runs in a single pass, but no dedicated mop-only mode was available in the version a fetched review tested.

Roborock Q8 Max+

The budget price is real (under $600 with self-empty dock) because obstacle handling is Reactive Tech rather than a camera. The robot detects obstacles without identifying them, and it holds roughly 1.5 inches off walls and baseboards, which costs edge and corner pickup.

The 350 ml electric tank means it vacuums and mops in one pass, but the dock only empties dust. There is no mop washing or auto-dry, so the cloth is attached, rinsed, and dried by hand every time.

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.

Lefant M5 Pro Robot Vacuum and Mop
Homes with frequent floor clutter or loose cables
A fetched review found the robot can drag or run over small objects it does not detect with its camera-less sensor array.
Buyers wanting fully mopped edges and baseboards
A fetched review measured roughly 7cm of unmopped space along edges since the roller mop does not extend to the sides.
Buyers needing a confirmed multi-year reliability record
The model launched around January 2026; independent field and failure data remain limited.
Roborock Q8 Max+
Cluttered homes with toys, cords, or obstacles
Reactive Tech detects obstacles without identifying them, so cords, socks, and pet waste are not recognized as distinct hazards. Clutter still needs a pre-run pickup or app no-go zones.
High-pile carpet homes
Automatic carpet boost raises suction on detection and the dual rubber rollers agitate pile, but deep extraction from thick carpet stays a job for an upright. Expect surface pickup on high pile.
Owners wanting a dock that washes the mop
The Q8 Max+ mops, but the RockDock Plus only empties the dust bin. The mop cloth is attached, rinsed, and dried by hand after every mopping run.

What stays your job

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

Lefant M5 Pro Robot Vacuum and Mop
  • Cadence: Empty the roughly 120-day dust bag and rinse the base station periodically.
  • Water/solution refill: Refill the dock’s clean-water supply on a shorter, unspecified cadence than the dust bag.
  • Setup: Set no-go zones and multi-floor maps once in the app.
  • Manual pickup: Clear cables, cords, and small objects before cleaning runs since the camera-less sensor array can miss them.
Roborock Q8 Max+
  • Weekly: Dust bin empty from robot (dock does the work, but manual verification suggested).
  • After each mopping run: Rinse and dry the mop cloth by hand; the dock does not wash it.
  • Every 2-4 weeks: DuoRoller hair removal and cleaning (~5 minutes).
  • Monthly: Main filter replacement or cleaning (~$6-10 per filter).
  • Quarterly: Dock contact cleaning to prevent oxidation and connection issues.
  • Every 6-8 weeks: Dock dust bag replacement (2.5 liter bag, rated up to seven weeks).
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.
