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.

03 Measured against the class

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.

iRobot Roomba Plus 575 Combo

Compact footprint, compact suction: the 46% smaller chassis that fits under beds and sofas runs 25,000 Pa, below iRobot’s higher-suction combo tiers.

Runtime and weight go undocumented because iRobot has not published them, even though suction, dock temperatures and mop mechanics are all fully specified.

Seven weeks old: no independent reliability record exists yet.

Shark Matrix Plus

Multi-pass grid coverage is thorough but slow: crossing the same area repeatedly takes longer per room than a single-sweep pattern.

The base automates bin emptying for up to 60 days but does nothing with water, so filling the tank, rinsing the pad and swapping it stay manual.

Vacuuming runs unattended while mopping is a job you set up: the 2-in-1 saves buying two machines, but only one half of it is autonomous.

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.

iRobot Roomba Plus 575 Combo
Homes larger than roughly 3,000 sqft on one level
iRobot has not published runtime, weight or recharge-and-resume specifics for this SKU, so single-charge coverage of large single-level layouts is unconfirmed.
Thick, high-pile or shag carpet needing deep-clean suction
25,000 Pa is iRobot's compact-tier suction, below its higher-suction AutoWash-dock combos; dense high-pile pickup is not independently documented for this model.
Buyers who need a proven multi-year reliability record before purchase
The 575 Combo launched 28 Jul 2026; no independent teardown, failure report or owner-forum thread yet exists to evaluate the dock or the robot itself.
Owners needing confirmed battery runtime before buying
iRobot has not published runtime, battery capacity or the robot's weight for this SKU, so per-charge coverage cannot be confirmed ahead of purchase.
Owners wanting truly zero-touch maintenance with no dock refills
The AutoWash Dock automates emptying, washing and drying, but its water reservoir and detergent supply still need periodic manual refills despite the documented months-long hands-off window.
Shark Matrix Plus
Multi-level homes or stair-dependent layouts
Robot cannot navigate stairs. Each floor requires separate mapping and scheduling, and the base has to be moved with it or duplicated per level.
Floors that are rarely cleared before a run
The robot routes around obstacles it detects, but cords, socks and pet toys left down still need picking up first. Households that will not do a pre-run tidy get less complete coverage.
Large homes requiring continuous same-day mop coverage
The 300ml tank is filled by hand and the base does not refill it, so mopping a large floorplan means interrupting the run. Not autonomous for sequential mopping.
Households expecting vacuum and mop in one hands-off pass
Mopping is a manual setup: the pad and the 300ml tank are prepared by hand and the base does nothing with water. Vacuuming is the autonomous half of the machine; mopping is a job you start.
Cloud-privacy-focused households
Room maps, cleaning history and schedules are held in the Shark account rather than only on the robot. Navigation is LiDAR, so no camera imagery of the home is involved, but there is no documented local-only mode.
Owners requiring full autonomy without supervision
Bin emptying at the base is handled for up to 60 days, but retrieving a stuck robot, filling the mop tank and swapping pads remain owner tasks.

What stays your job

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

iRobot Roomba Plus 575 Combo
  • Weekly: Check the DualClean spinning mop pads for hair or debris wrap before mop-inclusive runs.
  • Weekly: Empty the onboard dustbin if the AutoWash Dock is skipped for a run away from the dock.
  • Monthly: Clear hair or debris from the main brush and swiveling side brush.
  • Monthly: Refill the AutoWash Dock’s detergent supply used in the ~167°F pad-wash cycle.
  • Every 3-6 months: Replace the onboard filter to help maintain suction near the rated 25,000 Pa.
  • Every 3-6 months: Wipe the ClearView Pro LiDAR turret and PrecisionVision sensor housing free of dust.
  • As needed: Empty and rinse the AutoWash Dock’s clean and waste water reservoirs when the app prompts.
Shark Matrix Plus
  • After every mopping run: Rinse the mop pad and empty any water left in the tank.
  • Weekly: Check the side brush and brushroll for wrapped debris; fill the 300ml tank before each mopping run.
  • Monthly: Clean dock sensors and charging contacts with a dry cloth; wipe the LiDAR turret and the cliff sensors on the underside.
  • Every 30-60 days: Empty the bagless base, which is rated to hold 60 days of debris.
  • Every 3-6 months: Replace or deep-clean the mop pad. The brushroll is self-cleaning and tangle-resistant, so hair removal is an occasional check rather than a routine chore.
  • Annually: Replace the base filter (cost $12-18) and inspect the brushroll and side brush for wear.
  • As needed: Retrieve the robot if it wedges under low furniture, clear cords before a run, reset Wi-Fi after router changes.
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.
