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.

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?

04 Ownership

What the numbers leave out.

The trade-off

What each design gives up to be good at what it is good at.

Dyson 360 Vis Nav

Premium price ($1,199) funds suction power and real-time obstacle detection, not dock automation. The dustbin remains manual: you are paying for cleaning power, not convenience.

Cleaning performance is strongest on hard floors and low-to-mid pile; owner reports show reduced effectiveness on shag and high-pile carpet despite the 65 air watt rating.

Xiaomi Robot Vacuum X20 Max

The hot-water mop wash is real, but it costs upfront. Dock price is $150-200 higher than vacuum-only competitors; mop-pad longevity gains repay roughly 18-24 months of typical use.

8000Pa suction performs well, but noise and power draw scale with it. Owner reports cite 70+ dB in max mode, and running at that setting draws the battery down faster, so a large floor area takes more dock returns to finish.

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.

Dyson 360 Vis Nav
Hands-off operation seekers
Manual dustbin emptying every 1-3 cycles conflicts with zero-touch operation; the 360 Vis Nav has no auto-empty dock. Not suitable for owners wanting to forget about maintenance.
Small apartments or modest-size homes
In spaces under 2,000 sqft, mid-tier LiDAR vacuums deliver comparable coverage at a materially lower price. The documented advantage at this price is suction power, which matters less in smaller homes with lighter soil loads.
Budget-conscious buyers
Priced at the category ceiling; competitors offer Level III autonomy and self-emptying at lower price points. Suction power is what the premium buys.
Homes with thick, high-pile carpet
Owner reports document higher motor load and occasional suction loss on shag and deep-pile surfaces despite peak power rating. Standard and low-pile surfaces are within documented capability.
Xiaomi Robot Vacuum X20 Max
High-pile carpet or shag homes
Owner reports document suction loss and brush clogging on shag. The mop pads lift 10 mm on carpet detection, so the constraint here is pile depth rather than the pairing of mop and carpet.
Renters or frequently rearranged layouts
Dock footprint is substantial (16-20 inches deep); perimeter mapping relies on fixed setup. Layout changes reset mapping.
Homes with 5 GHz-only Wi-Fi networks
Xiaomi flagships support 2.4 GHz only. Networks without legacy band require secondary band or band-steering router configuration.
Owners wanting lowest total cost of ownership
Mop pads (~$18-24 per pair), water-tank filters, and brush replacements add $80-120 annually; dock itself carries premium vs mid-tier alternatives.

What stays your job

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

Dyson 360 Vis Nav
  • Daily: Empty dustbin if shedding is high (multi-pet homes); weekly for low-shedding households.
  • Weekly: Tap out the washable filter; rinse monthly and air-dry fully before reinstalling.
  • Monthly: Replace filter pack if clogging persists (~$20 per replacement set).
  • Every 3-6 months: Clean brush rollers and side brush; check dock charging contacts for debris.
  • Annually: Inspect wheel treads for wear; replace if grip is lost (~$15 per wheel pair).
  • As needed: Manually retrieve robot from under-furniture traps; digitally update no-go zones.
Xiaomi Robot Vacuum X20 Max
  • Weekly: Inspect and remove hair from main brush; rinse dust bin if over-full.
  • Monthly: Clean filter (dry brush or tap-out); rinse water tank.
  • Every 3-6 months: Replace mop pads (~$20-24 per pair); replace dust-bag insert (~$20-30 per set).
  • Annually: Descale water tank if hard water present; inspect dock nozzles for mineral buildup.
  • As needed: Replace main brush if hair and debris persist after cleaning (roughly 6-9 months in shedding homes).
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.
