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.

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.

Not compared, because fewer than two of these robots carry a published figure: Price, Runtime, Charge time, Noise, Weight.

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 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.

MOVA E50 Pro Ultra

Skipping a camera keeps video out of the home, and testsiegertv scored obstacle avoidance 6.5 of 10.

The MaxiReach pad reaches along edges, while the fixed side brush left debris in testsiegertv’s corner test.

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 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.
MOVA E50 Pro Ultra
Floors often scattered with cables or small toys
testsiegertv saw it push a charging cable and small toys, and Maniaques reports cables and small toys often swallowed.
Kitchens where corner crumbs matter
The side brush does not extend, and testsiegertv's corner test left most oat flakes behind.
High-pile rugs
The pads lift 10.5 mm but cannot be dropped off, so testsiegertv suggests setting high-pile rugs as avoid zones.
Long-haired pets without the optional brush
The standard rubber brush needs regular hair removal, per Maniaques; the CleanChop brush is sold separately.

What stays your job

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

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.
MOVA E50 Pro Ultra
  • As needed: Refill the 5 L clean water tank and detergent tank, and empty the 4.5 L dirty water tank; Maniaques notes the tanks must be removed to check their levels.
  • As needed: Replace the 3.2 L dust bag, which lasts up to 100 days per MOVA and testsiegertv.
  • As needed: Remove hair from the rubber main brush, per Maniaques.
  • As needed: Rinse the dock’s filter basin under water, per testsiegertv.
  • As needed: Replace mop pads, side brushes and the dustbin filter; MOVA sells E50 series packs.
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.
