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

One action, on command
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 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 S70 Pro Roller
Hard-floor mopping and vacuuming scored top marks in I’mTech’s test, while carpet edges and corners were left uncleaned.
The turretless dToF sensor keeps the robot 91.5 mm tall, and I’mTech saw it dither while finding its bearings.
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 S70 Pro Roller
- Deep or long-pile carpet
- I'mTech rates carpet vacuuming up to 10 mm pile only and saw it miss carpet edges and corners.
- Owners who never want to clean the roller
- After four test homes, I'mTech found the roller and the area under it needed washing by hand.
- Cupboards with tight top clearance
- The dock stands 496 mm tall and needs about 300 mm above it to lift out the water tanks, per I'mTech.
- Buyers who want voice assistant control
- I'mTech found no Alexa, Google, Siri or Matter support.
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 S70 Pro Roller
- After every use: Empty the 4.5 L dirty water tank, per I’mTech.
- As needed: Refill the 5 L clean water tank and the 600 ml detergent tank.
- As needed: Hand-wash the roller and roller bay; I’mTech found this necessary after four test homes.
- As needed: Replace the 3.2 L dust bag, about every 2-4 months per I’mTech.
- Every 3-6 months: Replace side brushes and the robot dustbin filter, per I’mTech.
- As needed: Replace the roller mop every 1-3 months and the CleanChop main brush every 6-12 months, per I’mTech.

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.
