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.

Ecovacs Deebot T20 Omni

Hot-water wash adds cleaning capability but not autonomy because the dock cycle is 2-3 hours; autonomous operation remains scheduled, not on-demand.

TrueDetect 3D replaces the X1 Omni’s camera, which takes in-home imaging off the machine but also removes camera-based object recognition; obstacle detection is laser-only.

Roborock Qrevo Edge S5A

The Multifunctional Dock 3.0 takes over emptying, washing, drying and refilling, but it is a full-size station that needs a permanent spot near an outlet, and its own clean and waste water tanks are still filled and emptied by hand.

Standard dock requires monthly intervention, yet the robot maps like a $1,200 flagship; capability ceiling is high, but ownership floor is unchanged.

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 T20 Omni
High-pile or dense Berber carpet homes
Mop lifting is marginal; owner reports show reduced effectiveness on high-pile surfaces. Brush entanglement remains an issue.
Owners unable to accommodate periodic app-based scheduling
Hot-water wash cycle is 2-3 hours; scheduling conflicts with typical household routines unless owner programs into a low-traffic window.
Homes with sparse Wi-Fi 2.4 GHz coverage
Both robot and dock require stable 2.4 GHz connectivity. 5 GHz-only networks are not supported.
Compact apartments under 1,000 sqft with limited outlet proximity
The station needs a 120V outlet and a clear floor position 17.6 x 16.9 inches with 22.8 inches of height above it. No plumbing or drain is involved, but in a studio that is a permanent piece of floor furniture.
Roborock Qrevo Edge S5A
Homes with no permanent floor space for a full-size station
The Multifunctional Dock 3.0 holds water tanks, a dust bag and a drying fan. It needs a fixed position on a hard floor next to an outlet and is not a base that gets stowed between runs.
Owners who want a dock with no disposable consumables
The station collects into disposable dust bags rated for up to seven weeks. Bags, mop pads and the filter are ongoing purchases rather than washable-forever parts.
Owners wanting hands-off operation
Dust runs for weeks unattended and the mop pads are washed and dried automatically, but the station's own clean and waste water tanks are filled and emptied by hand. This is low-touch, not no-touch.
WiFi-dependent smart-home integrations
Works over 2.4 GHz Wi-Fi. Homes running 5 GHz-only networks need a separate 2.4 GHz access point for the robot to join and stay connected.

What stays your job

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

Ecovacs Deebot T20 Omni
  • After every use: Check mop pads for hair tangles and debris; the station washes and dries them automatically.
  • Weekly to fortnightly: Clean the motor filter and pre-filter; wipe the station tray and exterior.
  • As the station prompts: Empty the 4 L dirty-water tank, refill the 4 L clean tank, and replace the dust bag when full.
  • Every few months: Replace the motor filter and pre-filter.
  • Every 6-8 months: Replace mop pads, brush roll and side brush.
Roborock Qrevo Edge S5A
  • Weekly: Check the main brush and side brush for wrapped hair; refill the station’s clean-water tank and empty its waste tank.
  • Monthly: Rinse the dust filter and wipe the LiDAR window and cliff sensors with a microfiber cloth.
  • Up to every 7 weeks: Replace the dock dust bag when the app reports it full; Roborock rates the bag for up to seven weeks of collection.
  • As wear shows: Replace mop pads, filter and brushes. Roborock publishes no fixed interval or price for these parts.
  • As needed: Wipe the dock tray if residue builds up between its own hot-water self-clean cycles.
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.
