Will it fit under my furniture?

The robot stands 4.1 inches tall, so it slides under most sofas and cabinets with a few inches of clearance. The dock is larger at 23.2 inches tall and 19.4 inches deep, so plan floor space near an outlet.

How often will I need to empty the dock?

The dock uses a 3.2 L dust bag, so it holds weeks of debris before needing a swap. Its 4.5 L clean water tank and 4 L dirty water tank also last many sessions between refills and empties.

Can it handle thresholds between rooms?

It clears obstacles up to 20 mm tall, so it can cross most door sills and low thresholds between rooms without getting stuck.

How much control do I get over cleaning zones?

You can set no-go zones and store multi-level maps for up to 4 floors. That lets you block off areas and pick specific rooms to clean on each level.

Does it keep the mop pads from smelling?

The dock auto-washes the pads with water heated to 140°F and adds detergent automatically. It also air-dries the pads afterward, which helps prevent musty odors between cleans.

Which voice assistants work with it?

It supports both Amazon Alexa and Google Assistant, so you can start or stop cleaning with voice commands through either platform.

The good

Pros

8,300 Pa suction with dual rubber brushes clears everyday dust and pet hair
LiDAR plus RGB camera and 3D structured light navigate tight spaces reliably
Dock empties dust, refills water, and washes mop pads at 140°F on its own
210-minute runtime covers large homes on a single charge
Stores maps for up to 4 floors with no-go zones and selective room cleaning
Liftable mop and main brush protect carpet during mopping runs

The trade-offs

Cons

Vibrating mop pads scrub less effectively than dual spinning pads on stuck-on messes
No anti-tangle brush design, so long hair can wrap around the rollers
The dock cannot clean itself, so its tray needs occasional hand cleaning

How the numbers stack up

Performance vs the category

At 8,300 Pa, suction is on the modest side (median 15,000 Pa).
Runtime comes in at 210 min, right around the category median (category median 200 min).
At 20 mm, threshold clearance is about average for the robots we track (median 20 mm).
Mop pressure of 3.5 N is on the modest side (category median 10.5 N).
Dock dust bag comes in at 3.2 L, larger than most, ahead of about 59% of robots (category median 3 L).

Who it's for

Owners of larger, mostly hard-floor homes who want a truly hands-off routine. It suits multi-story households that value strong navigation, room-by-room control, and a dock that handles emptying, refilling, and pad washing on its own.

Who should skip it

Anyone who needs deep scrubbing of dried, sticky messes should look at a dual spinning mop instead. Homes with heavy long-hair shedding may also struggle without an anti-tangle brush.

The bottom line

Our take

The Mova S20 Ultra pairs confident LiDAR navigation with a dock that automates nearly all the upkeep, making daily cleaning genuinely low-effort. Its vibrating mop and non-tangle brushes hold it back from top-tier scrubbing, but for hard-floor homes wanting convenience, it delivers.
