Does it vacuum and mop in the same run?

Yes. It vacuums and mops, and the dock washes the mop roller after mopping. You can also run vacuum-only passes on carpet.

How does the self-washing dock work?

The dock sprays and scrubs the PowerSpin roller with hot water and downward pressure, then dries and stores it. It also empties debris, which iRobot says gives up to 90 days of hands-free maintenance.

Will it handle pet hair?

The hair-cutting bristle brush and anti-tangle Edge-Sweeping brush are designed to reduce hair wrap. Owners report fewer tangles than with older brushes.

Can it map more than one floor?

Yes. PrecisionVision AI and ClearView Pro LiDAR map up to three levels, so it can clean multiple floors with saved maps.

What comes in the box?

The robot, the AutoWash dock, an extra AutoEmpty bag, an extra filter, an extra side brush and a bottle of cleaning solution.

Is it worth it over a plain robot vacuum?

If you want mopping without washing pads by hand and have hard floors plus carpet, the self-wash dock and stronger suction justify it. If you only vacuum carpet, a simpler Roomba does the job for less.

What reviewers say

Owners rate it very highly, with the self-washing mop and strong suction standing out. Most praise how little hands-on maintenance it needs. A few note the dock's size and that the mop roller still needs periodic cleaning.

What people mention

Self-wash dockPraisedOwners like that the dock washes the mop roller with hot water so they rarely handle a wet pad.
SuctionPraisedUsers report stronger carpet pickup than earlier Roomba models.
Hair wrapPraisedThe cutting brush and anti-tangle side brush keep long hair from wrapping the rollers.
Dock sizeCriticisedSome owners find the AutoWash dock large and hard to place in tight rooms.
Mop upkeepMixedThe mop is largely self-cleaning, but owners say the roller and dock tray still need periodic manual cleaning.
