Will it fit under my furniture and clear thresholds between rooms?

At 3.8 inches tall, it slides under many sofas and cabinets. It climbs obstacles up to 20 mm, so most door sills and low thresholds are no problem.

How much space does the charging dock need?

The dock measures 20.5 inches tall, 13.4 inches wide, and 19.2 inches deep, so plan for a sizable footprint near an outlet. It handles auto-emptying, mop washing, and air drying in that space.

Can I keep it out of certain rooms or areas?

Yes, no-go zones let you block off spaces like a pet feeding station or a room with cables. Combined with its multi-level maps for up to 4 floors, you get room-by-room control across the whole home.

How does it keep the mop pads from smelling?

The dock washes the mop pads automatically after cleaning, then air-dries them so they do not stay damp. It also collects the waste water on its own into the 3.5 L dirty tank.

Which voice assistants does it work with?

It supports Amazon Alexa, Google Assistant, and Apple, so you can start or stop cleaning by voice. You also get 30 mop moisture levels to dial in through the app for different floor types.

Does it handle long hair and pet fur without tangling?

Yes, it uses a single rubber main brush with anti-tangle design to reduce hair wrapping. That helps keep maintenance low in homes with shedding pets or long hair.

The good

Pros

LiDAR mapping stores up to 4 floor plans for whole-home coverage.
Dual spinning mop pads actively scrub hard floors, not just wipe them.
180 minutes of runtime handles large layouts on a single charge.
Auto-emptying dock, mop washing, and air drying keep upkeep minimal.
Auto-refilling clean tank tops off the robot mid-clean without your help.
3D structured light avoids cords, shoes, and toys during runs.

The trade-offs

Cons

10,000 Pa suction trails higher-powered rivals on deep-pile carpet.
The mop turns at just 200 RPM, gentler than stronger spinning systems.
The dock cannot rinse and clean itself between mop washes.

How the numbers stack up

Performance vs the category

Suction of 10,000 Pa is on the modest side (category median 15,000 Pa).
Runtime comes in at 180 min, on the modest side (category median 200 min).
Threshold clearance of 20 mm is about average for the robots we track (category median 20 mm).
At 64 dB, noise is about average (median 64 dB).

Who it's for

Multi-story households with mostly hard floors who want set-and-forget cleaning. It suits people who value tidy mopping and light upkeep, and who like controlling rooms and no-go zones from an app.

Who should skip it

Homes packed with thick, high-pile carpet that needs heavy suction, or anyone wanting the most aggressive mop scrubbing available, will be happier with a higher-powered model.

The bottom line

Our take

The QV 35S delivers genuinely low-maintenance, whole-home cleaning with sharp LiDAR mapping, active dual spinning mops, and a dock that empties, washes, and refills on its own. Cleaning power sits at the mid-range, so it shines on hard floors more than deep carpet.
