All robot vacuums. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.
Where each one suits you.
The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.
| Condition | Roomba Max 775 Combo |
|---|---|
| Home size | |
| Under 1,500 sqft | GoodCapable but overkill for apartment-sized spaces; faster-cycling mop-only units suit compact homes better. |
| 1,500 – 3,000 | Good30,000Pa suction completes most 2-floor homes in one run; hot-water mop ideal for kitchen and bathroom flooring. |
| Over 3,000 | GoodExtended runtime and auto-empty dock handle large homes across multiple rooms; multi-floor mapping navigates complex layouts. |
| Primary floors | |
| Hard floors | GoodHot-spray mop and motorized wash cycle excel on tile, hardwood, and vinyl; no manual water changes required. |
| Low / medium pile | Good30,000Pa suction and motorized side brush deliver reliable pickup on low-pile and twist carpet; mop compatibility requires no-mop zones. |
| High pile / shag | DependsiRobot flagships document suction loss on shag and high-pile; mop performance on thick carpet may require manual intervention on heavily matted areas. |
| Mopping needs | |
| Vacuum only | GoodStrong vacuum; the mop lifts or detaches when not needed. |
| Light mopping | GoodActive mopping system covers routine floors easily. |
| Frequent mopping | GoodPressure or rotating mop with self-wash is built for frequent mopping. |
| You want to… | |
| Empty bin myself | GoodAuto-empty and hot-water dock reduce daily contact, but weekly water-tank refills, mop-pad swaps, and dock cleaning remain necessary. |
| Empty occasionally | GoodHot-water dock and motorized wash cycle handle most routine maintenance; weekly checks and monthly consumable swaps keep effort moderate. |
| Set-and-forget | PoorHot-water dock and mop-pad washing require weekly intervention; no truly set-and-forget configuration available for combo units. |
A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
What the score is built from.
Nine inputs across three pillars, each weighted as shown and each scored so more is better. A robot can lead on one and trail on another, which is the point of showing them apart.

How far apart is a long way?
A number only means something next to the spread it sits in. Each track is the real range across every classified robot in the class, with the median marked.
These robots share no measured specification with enough published figures to plot. That is a gap in the record, not a finding about the robots.
What the numbers leave out.
Written on each record, and the only thing here every robot on the site carries.
The trade-off
What each design gives up to be good at what it is good at.
iRobot Roomba Max 775 Combo
You are paying flagship money for the dock rather than the navigation. The AutoWash Dock is not new hardware, it has been iRobot’s mop-washing base since the Combo 10 Max in 2024, but it is where most of the price and all of the floor space goes.
Hot-water capability removes manual mop-fill friction, but it shifts dock failure modes from simple (a clogged nozzle) to compound (water circulation, heating, the roller wash cycle). Recovery means dock troubleshooting, not just a part swap.
Longitudinal data is thin. The machine launched in June 2026, so owner reports on roller wear, the dock’s water circuit and long-run map stability are still sparse. The classification rests on published specification more than on accumulated field evidence.
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 775 Combo
- Homes with frequent layout changes
- The stored map is what the robot routes against, and a major furniture rearrangement means updating it before zones and schedules line up again. Lighting is not part of this: LiDAR maps in the dark.
- Renters or homes with restrictive power outlet placement
- The AutoWash Dock needs permanent AC power and a dedicated footprint of 17.7 x 16.7 x 17 in at about 19 lb. There is no battery-dock option, and moving the dock means the robot has to re-establish itself against the map. Smaller fixed-dock units suit temporary living better.
- Owners prioritizing absolute minimum maintenance
- A dock with clean and dirty water tanks is more to look after than an auto-empty base: tanks to fill and drain, a wash tray to wipe, and a debris bag to change. An auto-empty-only vacuum has one of those chores.
- Single-floor apartments under 1,500 sqft seeking mop-only performance
- Oversized for a mop-only home in both senses: the robot is 14.7 in front to back and the dock claims a permanent 17.7 by 16.7 in of floor. Vacuum-to-mop time is weighted toward vacuuming, and a dedicated mop unit is simpler in a compact space.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
iRobot Roomba Max 775 Combo
- Weekly: Refill the clean-water tank and empty the dirty-water tank; wipe the wash tray.
- Monthly: Clear hair from the brushes and the roller mop; clean the side brush, wheels and sensor windows.
- Every 3 months: Replace the dock’s debris bag, which iRobot rates for up to three months of collection.
- Every 3-6 months: Check the dock’s water lines and tanks for mineral buildup if you fill with hard water.
- Annually: Replace the robot’s filter and inspect the dock’s hose connections for cracks.
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.
| Robot | Evidence status | Sources reviewed | Last assessed |

Evidence status counts the sources behind a classification, not their kind. A high count can be maker documentation and price coverage, so read it as how much was reviewed rather than as independent testing. How we weigh evidence.
