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.

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.

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.

Lefant M5 Pro Robot Vacuum and Mop

The all-in-one dock reduces manual dust and mop-wash upkeep to a roughly 120-day cadence, but the camera-less sensor array trades some object-detection accuracy for that design.

Combined vacuum-and-mop cleaning runs in a single pass, but no dedicated mop-only mode was available in the version a fetched review tested.

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.
Lefant M5 Pro Robot Vacuum and Mop
Homes with frequent floor clutter or loose cables
A fetched review found the robot can drag or run over small objects it does not detect with its camera-less sensor array.
Buyers wanting fully mopped edges and baseboards
A fetched review measured roughly 7cm of unmopped space along edges since the roller mop does not extend to the sides.
Buyers needing a confirmed multi-year reliability record
The model launched around January 2026; independent field and failure data remain limited.

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.
Lefant M5 Pro Robot Vacuum and Mop
  • Cadence: Empty the roughly 120-day dust bag and rinse the base station periodically.
  • Water/solution refill: Refill the dock’s clean-water supply on a shorter, unspecified cadence than the dust bag.
  • Setup: Set no-go zones and multi-floor maps once in the app.
  • Manual pickup: Clear cables, cords, and small objects before cleaning runs since the camera-less sensor array can miss them.
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.
