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.

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: Suction.

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 705 Vac

Peak suction trails the category leaders: iRobot publishes no Pascal figure for the 705 and rates it at 180 times the 600 series, while third-party figures put it near 13,000 Pa, roughly 5,500 to 17,000 Pa below current Roborock flagships depending on which one is meant. The 705 answers carpet with Carpet Boost, four suction levels and anti-tangle rubber brushes rather than with peak pressure.

Roborock Q8 Max+

The budget price is real (under $600 with self-empty dock) because obstacle handling is Reactive Tech rather than a camera. The robot detects obstacles without identifying them, and it holds roughly 1.5 inches off walls and baseboards, which costs edge and corner pickup.

The 350 ml electric tank means it vacuums and mops in one pass, but the dock only empties dust. There is no mop washing or auto-dry, so the cloth is attached, rinsed, and dried by hand every time.

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 705 Vac
Homes that need mopping as well as vacuuming
This is the vacuum-only SKU and it does not mop. iRobot sells a Combo version of the same platform that does, and the two listings read almost identically, so the SKU is worth confirming before purchase.
Owners wanting mopping and vacuuming in one cycle
No mopping arm or tank. Requires separate unit or manual floor care. Adds operational complexity if kitchen / entryway spills are frequent.
Owners who do not want a consumable dock at all
The AutoEmpty dock is bagged. iRobot rates a bag at up to 75 days and the box includes one spare bag and one spare filter, after which bags run about $10 to $15 each. A bagless dock or a bin-only robot avoids that line item entirely.
Roborock Q8 Max+
Cluttered homes with toys, cords, or obstacles
Reactive Tech detects obstacles without identifying them, so cords, socks, and pet waste are not recognized as distinct hazards. Clutter still needs a pre-run pickup or app no-go zones.
High-pile carpet homes
Automatic carpet boost raises suction on detection and the dual rubber rollers agitate pile, but deep extraction from thick carpet stays a job for an upright. Expect surface pickup on high pile.
Owners wanting a dock that washes the mop
The Q8 Max+ mops, but the RockDock Plus only empties the dust bin. The mop cloth is attached, rinsed, and dried by hand after every mopping run.

What stays your job

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

iRobot Roomba Max 705 Vac
  • Weekly: Check the dual rubber brushes for hair wrap and clear the edge-sweeping brush.
  • Monthly: Clean or replace the robot’s filter; inspect the dock brush and charging contacts.
  • Up to every 75 days: Replace the AutoEmpty dock bag, which iRobot rates at up to 75 days. The box ships with a spare bag and a spare filter.
  • Annually: Clean the LiDAR window and the PrecisionVision camera, and inspect the dock mechanics.
Roborock Q8 Max+
  • Weekly: Dust bin empty from robot (dock does the work, but manual verification suggested).
  • After each mopping run: Rinse and dry the mop cloth by hand; the dock does not wash it.
  • Every 2-4 weeks: DuoRoller hair removal and cleaning (~5 minutes).
  • Monthly: Main filter replacement or cleaning (~$6-10 per filter).
  • Quarterly: Dock contact cleaning to prevent oxidation and connection issues.
  • Every 6-8 weeks: Dock dust bag replacement (2.5 liter bag, rated up to seven weeks).
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.
