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.

Any task, any setting

Handles new obstacles without help

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.

None of these robots carries a scored assessment yet, so there is nothing to plot here. The classification and evidence below still apply.

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.

Dreame L50s Pro Ultra

100°C mop washing and a 4 cm climb are the headline, and no independent test has yet measured either.

The dock handles dust for up to 100 days; water still means tanks unless you buy the hookup kit.

iRobot Roomba Max 875 Combo

You are paying for a claimed 3x carpet improvement that nobody outside iRobot has independently measured.

Hot-water roller washing removes manual mop upkeep because the dock handles the wash and dry cycle itself; it also converts a simple nozzle clog into a heating-circuit and pump fault to troubleshoot.

Zero field history at launch: every dependability figure here rests on a spec sheet, not an ownership record.

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 L50s Pro Ultra
Buyers in the United States
Dreame sells it in India and a Benelux retailer lists it; no US sale is announced.
Owners who never want to handle water tanks
The 4.5 L clean and 4.0 L used tanks are filled and emptied by hand unless the separately sold water hookup kit is fitted.
Buyers who want independent cleaning results first
Smartprix has published only first impressions, with a full review still to come; no outlet has published test results.
Low furniture under 11 cm
Dreame lists the robot at 103.8 mm tall.
iRobot Roomba Max 875 Combo
Renters or homes without dedicated dock floor space
The AutoWash Dock needs permanent AC power and a fixed footprint; moving it means the robot has to re-orient against its stored LiDAR map, which is disruptive for temporary living situations.
Owners of delicate, fringed or tasseled area rugs
SealForce lowers a physical skirt around the cleaning head on carpet detection; iRobot has not published guidance on tasseled or loose-weave rugs, and a lowering skirt is a plausible snag point worth flagging.
Multi-floor homes wanting one dock per level
iRobot has not published multi-dock or portable-basestation support for this model; carrying the robot between floors means re-establishing the map each time rather than a dedicated dock per level.
Buyers wanting an established field record before purchase
The Max 875 Combo shipped September 2, 2026. There is no owner-report history yet on roller wear, dock water-circuit durability, or long-run map stability.

What stays your job

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

Dreame L50s Pro Ultra
  • Weekly: Refill the 4.5 L clean water tank and empty the 4.0 L used water tank, unless the hookup kit is fitted.

  • As needed: Refill the floor cleaning solution for automatic dosing.
  • As needed: Replace mop pads, filters and brushes when worn.

iRobot Roomba Max 875 Combo
  • Weekly: Refill the dock’s clean-water tank and empty any wash-tray residue.
  • Monthly: Clear hair from the roller mop and side brush; wipe sensor windows and wheels.
  • Every 3-6 months: Replace the carbon AllergenLock debris bag, rated by iRobot for up to 90 days of collection.
  • Every 3-6 months: Check the dock’s water lines for mineral buildup if filled with hard water.
  • Annually: Replace the robot’s filter and inspect dock hose connections for wear.
  • As needed: Wipe the SealForce skirt and cleaning-head seal so it lowers and seals correctly on carpet.
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.
