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.

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 R1 Nurovi Dry
At $549 the R1 keeps the R2’s navigation and the same 21,000 Pa suction on the same 352 mm chassis. What the lower price removes is wet cleaning, not sensing: the R2 costs more for mop hardware and a washing dock, and both robots map the same way.
iRobot Roomba i3+ EVO
The i3+ EVO navigates without a camera, on a gyroscope and a floor-tracking optical sensor, which is what separates this tier from the i7 and s9 above it. The same choice cuts both ways: nothing on board can photograph a room, and the robot maps by driving the floor rather than by seeing it, so the map has to be rebuilt when the layout changes.
Mid-tier positioning means it sits between the budget i4 (no dock) and flagship s9+ (smaller body, more powerful brush); buyers must choose between saving $250 or gaining the s9+’s corner-reach design.
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 R1 Nurovi Dry
- Anyone needing mopping in the same device
- The R1 has no mop hardware at all. Buyers wanting wet cleaning need the R2 Wash+Dry or the R3 Spot+Scrub UV instead.
- US buyers wanting to purchase immediately
- No confirmed US ship date or retailer listing existed at launch; UK availability began same-day but the US window trails into later September.
- Buyers who want independent verification first
- No independent reviews, owner reports, or teardowns exist yet; every published figure so far traces back to Dyson's own launch materials.
- Buyers comparing on published battery or sound figures
- Dyson publishes run time and charge time but no battery capacity, no sound rating, and no onboard bin volume for the R1. Anyone shopping on those numbers has nothing to compare.
iRobot Roomba i3+ EVO
- Units still running pre-EVO firmware
- Imprint Smart Maps reached the i3 and i3+ as a free update in 2022. A unit that has not been updated lacks smart room selection and Keep Out Zones until it is.
- Owners avoiding recurring consumable costs
- The Clean Base uses disposable bags, rated at about 60 days of daily use per bag. Smart mapping itself is free and has never carried a subscription, but the dock's bags are an ongoing cost that the non-plus i3 does not have.
- High-pile or shag carpet households
- Owner reports document brush jamming and suction loss on high-pile carpets, consistent with other iRobot models in this tier.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Dyson R1 Nurovi Dry
- Every 90 days: Empty the dock’s 2.6 L bin; the dock is bagless and empties the robot after each run.
- Monthly: Clean the Twin-capture debris separator to maintain suction.
- Monthly: Wipe down and inspect the extending side sweeper for hair wrap.
- Every 3-6 months: Clean or replace the robot and dock filters; Dyson has not published an interval.
- As needed: Clear the anti-tangle brush bar of tangled hair and debris.
- Annually: Inspect wheels and sensors for dust buildup.
iRobot Roomba i3+ EVO
- Weekly: Check main brush for hair tangles and debris.
- Every 2-3 weeks: Remove main brush and side brush to clean matted hair and carpet fibers.
- Every 60 days: Replace the Clean Base bag (~$8-12 each). The robot empties itself into the dock, so there is no routine bin emptying.
- Monthly: Wipe dock interior and charging contacts for dust accumulation.
- Every 6-8 months: Replace side brush (~$20-25).
- Annually: Replace main brush (~$35-40) and HEPA filter (~$20-25).
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.
