All robot vacuums. Every measure below is plotted against the full class, so a difference can be read against how much the class itself varies.

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

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?

04 Ownership

What the numbers leave out.

The trade-off

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

Ecovacs Deebot T9+

Storing a map per floor removes relearning, but the robot cannot move between floors, so multi-level cleaning stays a manual carry.

The air freshener is a proprietary consumable: capsules are rated at up to 60 days each and change nothing about how the machine cleans.

Roborock Qrevo 2 Pro

The dock washes and dries mop pads at temperatures usually reserved for pricier docks, but structured-light sensors cannot see a charging cable the way a camera-equipped flagship can.

Auto Mop Removal parks the mop before carpet; carpet-border misreads however still let the robot begin mopping onto an area rug until a no-mop zone is drawn.

2.4GHz-only Wi-Fi: a home running a merged or 5GHz-first network may need to split bands before the robot will connect.

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.

Ecovacs Deebot T9+
Homes with high-pile carpet or thick shag
The mop plate has no automatic lift and comes off by hand before a run over deep pile. Vacuuming works on carpet; mopping and carpet cannot be scheduled into the same hands-off run.
Budget-conscious buyers seeking basic multi-floor coverage
TrueMapping premium adds $150-200 over single-floor models. Benefit diminishes in homes where one floor covers 80% of living space.
Owners avoiding consumable cartridges or frequent maintenance
The air freshener uses proprietary capsules, rated by Ecovacs at up to 60 days each. Mop pads are removed and washed by hand after mopping runs; the station handles dust only.
Roborock Qrevo 2 Pro
Floors with loose cables, cords, or ribbons
Independent testing found the robot picks up nearly every unflattened cable it crosses; its structured-light sensors cannot distinguish thin cords from open floor the way a camera can.
Networks that only offer 5GHz Wi-Fi
The robot connects on 2.4GHz exclusively; a router broadcasting only a 5GHz band, or one merged without a 2.4GHz option, will not complete setup.
Large homes above roughly 3,000 sq ft
No independent test of coverage above 3,000 sq ft was found; the 253-minute rated runtime is unconfirmed against a layout this size in a single session.
Deep or high-pile carpet needing verified deep-clean suction
20,000 Pa is a mid-tier suction figure and no independent test of thick, high-pile carpet performance has been published for this specific model.
Homes with area rugs needing hands-off no-mop zoning
A documented review found the robot began wetting a dining room rug before its boundary was manually outlined; carpet-edge detection is not fully automatic on rugs.

What stays your job

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

Ecovacs Deebot T9+
  • After mopping runs: Remove and wash the mop pad; the station does not wash or dry it.
  • Monthly: Clean the main filter and clear hair from the rubber brush and side brush.
  • About every 60 days: Replace the station dust bag, which Ecovacs rates at up to 60 days of hands-free operation, and the air freshener capsule if that feature is used.
  • Every 3-6 months: Replace the main filter and inspect the brush for wear.
  • Annually: Replace the main brush, side brush and mop pads as wear becomes visible.
Roborock Qrevo 2 Pro
  • Weekly: Check the main brush and side brush for tangled hair, cables, or cords.
  • Monthly: Empty or replace the dock’s self-sealing dust bag and wipe the water tank.
  • Every 3-6 months: Replace mop pads and inspect the main brush for wear.
  • Every 3-6 months: Rinse or replace the washable filter per manufacturer guidance.
  • Annually: Replace the side brush and check the dock’s heating element for scale buildup.
  • As needed: Reseat the dust-roller compartment if the robot will not dock; one review documented this out of the box.
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.
