Will the S8 fit under my furniture?

At 3.8 inches tall, it slides under many couches, beds, and cabinets. Its 13.9-inch width lets it navigate between chair legs and tighter gaps.

Can it handle thresholds between rooms?

It climbs obstacles up to 20 mm, so it clears most door sills and transition strips between rooms on the same floor without getting stuck.

Does it keep carpet dry while mopping?

Yes. The mop lifts 5 mm when it detects carpet, and Smart Carpet Cleaning boosts suction on rugs so the pad never drags moisture across them.

Can I block off certain areas?

Yes. It supports no-go zones through the app, so you can fence off pet bowls, cords, or a play area you would rather it avoid.

How adjustable is the mopping?

The mop offers 3 moisture levels and vibrates at 3,000 RPM with 6 N of pressure, so you can dial in a lighter pass or a wetter scrub for different floors.

How often do I need to empty the robot?

The onboard bin holds 400 mL and the water tank holds 300 mL. Without a self-emptying dock, plan to empty the bin and refill water by hand regularly.

The trade-offs

Cons

Vibrating mop pad scrubs less effectively than dual spinning or roller systems.
No self-emptying dock, so you empty the 400 mL bin by hand.
The dock cannot wash mop pads or refill the water tank automatically.
1-year warranty is shorter than what many competitors offer.

How the numbers stack up

Performance vs the category

At 6,000 Pa, suction is below the typical robot (median 15,000 Pa).
Runtime comes in at 180 min, on the modest side (category median 200 min).
At 3,229 sq ft, single-run coverage is larger than the typical robot (median 2,150 sq ft).
Threshold clearance of 20 mm is about average for the robots we track (category median 20 mm).
Noise comes in at 68 dB, louder than most (category median 64 dB).

Who it's for

Great for multi-story homes with a mix of hard floors and carpet, where strong vacuuming and reliable furniture navigation matter more than deep mop scrubbing. Ideal for owners comfortable with a little hands-on upkeep.

Who should skip it

Skip it if you want a fully hands-off setup with self-emptying and auto mop washing, or if scrubbing stuck-on kitchen messes is your main goal.

The bottom line

Our take

The S8 delivers dependable LiDAR navigation, solid suction, and genuine multi-floor mapping in a capable mid-range package. Its vibrating mop and manual dock upkeep are the tradeoffs, but for carpet-and-hardwood homes that value smart navigation over heavy scrubbing, it holds up well day to day.
