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.

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?

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.

Dreame X30 Ultra

MopExtend improves edge and corner coverage on the robot’s own detection, and the reach it adds is 4 cm, not a room’s worth. It is a mount that swings within the machine’s footprint, not an arm that extends past it.

Automatic pad detach and in-place washing remove the weekly mop chore. The price is a base station 23.2 inches tall on a 13.4 by 18 inch footprint that has to stay put beside an outlet.

iRobot Roomba Max 705 Vac

Peak suction trails the category leaders: iRobot publishes no Pascal figure for the 705 and rates it at 180 times the 600 series, while third-party figures put it near 13,000 Pa, roughly 5,500 to 17,000 Pa below current Roborock flagships depending on which one is meant. The 705 answers carpet with Carpet Boost, four suction levels and anti-tangle rubber brushes rather than with peak pressure.

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.

Dreame X30 Ultra
Homes above roughly 2,600 sq ft of continuous floor
Dreame states 243 m2, about 2,615 sq ft, on a single charge. Larger continuous layouts mean the robot recharges partway through and resumes, which lengthens the job rather than stopping it.
Owners wanting minimal dock footprint
The base station measures 13.4 by 18 inches on the floor and stands 23.2 inches tall, so it needs a permanent position against a wall beside an outlet rather than a cabinet slot.
Wi-Fi 5 GHz-only networks or band-locked systems
2.4 GHz is required to provision the robot and reach it from the app; without it there is no pairing, no scheduling and no multi-floor map management. The mechanical behaviors, MopExtend and the carpet pad handling, run on onboard detection and are unaffected by connectivity.
Budget-focused buyers
Street pricing $799-999 seats X30 Ultra in mid-to-premium range. Older Dreame models (L10s Ultra) deliver sealed-floor capability at $549-699 with lower arm-maintenance overhead.
Owners expecting a reaching arm
MopExtend is a mop mount that swings out 4 cm (1.57 in) within the robot's own footprint on edge detection. It does not extend into spaces the robot cannot drive to, and it plays no part in carpet coverage.
iRobot Roomba Max 705 Vac
Homes that need mopping as well as vacuuming
This is the vacuum-only SKU and it does not mop. iRobot sells a Combo version of the same platform that does, and the two listings read almost identically, so the SKU is worth confirming before purchase.
Owners wanting mopping and vacuuming in one cycle
No mopping arm or tank. Requires separate unit or manual floor care. Adds operational complexity if kitchen / entryway spills are frequent.
Owners who do not want a consumable dock at all
The AutoEmpty dock is bagged. iRobot rates a bag at up to 75 days and the box includes one spare bag and one spare filter, after which bags run about $10 to $15 each. A bagless dock or a bin-only robot avoids that line item entirely.

What stays your job

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

Dreame X30 Ultra
  • After every run: Handled by the station, which washes the mop pads in place with 60 C water and dries them with hot air; pads come off and go back on without owner involvement.
  • Every 3-4 weeks in typical use: Refill the 4.5 L clean water tank with ordinary tap water and empty the waste tank. The station dispenses Dreame’s own cleaning solution into the clean water.
  • Weekly: Wipe the station’s docking contacts and the robot’s sensor windows; clear hair from the main brush and side brush.
  • Every 3 months: Replace the auto-empty dust bag (~$15-20 per bag; expected lifespan 8-12 weeks in typical use).
  • Every 6 months: Replace main brush and side brush (~$30-40 per set), or as wear becomes visible.
  • As pads lose absorbency: Replace the mop pads. In-place washing extends their life but does not remove wear.
iRobot Roomba Max 705 Vac
  • Weekly: Check the dual rubber brushes for hair wrap and clear the edge-sweeping brush.
  • Monthly: Clean or replace the robot’s filter; inspect the dock brush and charging contacts.
  • Up to every 75 days: Replace the AutoEmpty dock bag, which iRobot rates at up to 75 days. The box ships with a spare bag and a spare filter.
  • Annually: Clean the LiDAR window and the PrecisionVision camera, and inspect the dock mechanics.
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.
