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.

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.

Ecovacs Deebot T30S Combo

Combo consolidation reduces device-count friction but increases failure-point surface area compared to single-unit alternatives.

Station-side pad washing at 158 F keeps a clean pad on the robot without an owner task, and the bill is a large permanent station position plus hand-filled clean and waste tanks.

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.
Ecovacs Deebot T30S Combo
Owners wanting a single compact appliance
The bundle is three things to house: a LiDAR robot, a separate 2.65 lb cordless stick vacuum with four attachment heads, and an Omni Station that needs a permanent floor position.
Minimalist or rental spaces
Large docking footprint limits placement options. No lightweight alternative if main unit fails or requires service.
Water-damage-sensitive environments
Mop tank, heated rinsing system, and dock drainage introduce water exposure risk. Unsuitable near electronics or carpeted basements.
Budget-conscious buyers
The bundle price covers a robot, a cordless stick vacuum and an Omni Station together. Buyers who want only the robot are paying for a second machine they may not use.
Owners requiring offline operation
App scheduling and firmware updates depend on cloud connection. No documented local-only mode; cloud dependency is hard requirement.

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.
Ecovacs Deebot T30S Combo
  • After every run: Handled by the Omni Station, which empties the dustbin, washes the mop pads at 158 F and dries them with hot air.
  • Weekly, or as mopping requires: Refill the 4 L clean water tank and empty the 3.5 L waste tank.
  • After every handheld use: Empty the handheld dust bin.
  • Monthly: Clean the LiDAR window and the TrueDetect 3D lens; check the ZeroTangle roller and side brush for wrapped fiber.
  • Roughly every 60 days: Replace the 3 L auto-empty dust bag, which is the interval Ecovacs rates it for.
  • As pads lose absorbency: Replace the mop pads. Station washing extends their life but does not remove wear.
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.
