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

II
Assisted
Runs preset routines, needs rescue
I
Manual
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.
MOVA V70 Ultra Complete
Reaching arms clean what a round robot circles around, and they add two more moving mechanisms to keep working.
Bagless emptying saves the cost of bags; the price is a loud empty cycle that Gear Diary flagged.
Roborock S8 Max Ultra with Refill & Drainage System
The dock takes over every water chore, and in exchange it needs plumbing work before its first run.
Structured-light obstacle avoidance keeps a camera out of the home; Vacuum Wars found the camera model avoided obstacles better.
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.
MOVA V70 Ultra Complete
- Households sensitive to a loud dock
- Gear Diary found the auto-empty cycle loud, though short.
- Floors with grout lines and dried residue in joints
- Basic Tutorials found dried residue in floor joints needed multiple passes, even though open-surface coffee stains cleared in one.
- Homes with low desk bases and platform furniture
- Basic Tutorials saw obstacle detection that was mostly reliable but once tried to climb a desk base.
- Buyers who want a camera-free robot
- The MOVA app includes remote camera viewing, per Basic Tutorials, so the robot carries a camera through the home.
Roborock S8 Max Ultra with Refill & Drainage System
- Renters or homes without a nearby water line and drain
- The dock must connect to a water supply and a drain within Roborock's stated distances, which many layouts cannot provide.
- Buyers who want a camera for obstacle recognition
- It uses structured light rather than a camera, and Vacuum Wars found the camera-equipped S8 MaxV Ultra avoided obstacles better.
- Dock sites behind a threshold over 2 cm
- Roborock's installation guidance warns against thresholds, tracks or steps above 2 cm between the dock and the cleaning area.
- Buyers who need an independent test of the plumbed version
- Vacuum Wars tested the standard-dock S8 Max Ultra and said it had not reviewed the refill and drainage variant.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
MOVA V70 Ultra Complete
- Weekly: Refill the 4 L clean-water tank and empty the 3.5 L dirty-water tank; Gear Diary got at least three mopping sessions per fill.
- Every 3-6 months: Empty and wash the bagless EcoCyclone dust container, rated for up to 100 days.
- As needed: Refill the two cleaning-solution compartments.
- Monthly: Rinse the dust container filter and wipe the DToF sensor and cliff sensors.
- As needed: Replace mop pads, side brush and main brush as they wear; spares ship in the box.
Roborock S8 Max Ultra with Refill & Drainage System
- As needed: Replace the 2.5 L dock dust bag; Roborock sells 6-packs.
- Every 3-6 months: Refill the 580 ml detergent tank, which Roborock says lasts over three months.
- As needed: Check the water inlet and drain connections for leaks, per Roborock’s installation notes.
- As needed: Replace mop cloths and edge mop cloths; Roborock’s US store sells both.
- As needed: Replace the washable filters and main brush pack, which Roborock’s US store sells for the S8 Max Ultra.
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.
