Best on Grok (avg #1.5), weakest on Claude (#18.0)
This model cleans and mops well and holds its own against a newer model in the line, though it trades some conveniences for a bulkier body and hair-tangle issues.
Owners love the advanced automation and quiet cleaning power, but mopping performance divides them—some find it excellent on tile while others struggle with coverage and water management.

About
What it is.
Roborock's S9 MaxV Ultra sits at the top of the brand's robot vacuum lineup, pairing suction cleaning with an automated mopping system in a single bagless, cordless unit. It works with a dock that handles washing and refilling duties for the mop, reducing the amount of manual upkeep the machine otherwise demands. Obstacle avoidance is handled through Roborock's camera-based ReactiveAI system, letting the unit navigate around furniture, cords, and clutter on its own.
Built for households that want whole-floor cleaning left to a machine rather than managed by hand, it integrates with Amazon Alexa for voice control and fits into a smart home routine alongside other connected devices. It's suited to anyone standardizing on Roborock's ecosystem for consistent, hands-off floor care.
The verdict
The S9 MaxV excels at automated carpet cleaning with strong suction and near-silent operation, earning consistent buyer praise, though its mopping function proves inconsistent—excellent on tile for some owners but unreliable in coverage and water management for others.

What owners single out
In their words
“My wife an I are very pleased with the S7 max and the dock. We had an irobot 8 series and the upgrade to mopping capabilities has been nothing short of amazing. Our house is one level, 90% tile, and short pile area rugs. Having had the new system for a few weeks our floors are very clean.”
Trebacz · verified purchase · us.roborock.com
“If you are buying this for the mopping feature, find a different company. This design has a ton of flaws. First, people buy a robot to avoid having to do extra work. We should not be required to wet the mopping pad before use. I have the dock clean the pad prior to use. It lasts for about 40 feet before leaving tiny wet strips on the floor. It also leaves wheel tracks in the mopping section.”

For you if
Look elsewhere if
You need a proven, low-risk robot vacuum you can trust to work consistently.
Roborock is an established brand with 424 buyer reviews showing 4.7/5 consensus. High reliability and maintenance ratings signal a mature, settled product with broad trust.
You want a flagship robot vacuum from an established, respected brand.
Roborock is a tier-3 brand with strong market presence; the MaxV Ultra is positioned as a flagship model with premium features and design, fitting the connoisseur's expectation of prestige and polish.
You demand top-tier cleaning performance and reliability from a robot vacuum.
High buyer rating (4.7/5, 424 reviews), strong cleaning power and automation, proven reliability. Mopping is mid-tier, which slightly tempers the perfectionist fit, but overall a near-flagship…
You love smart home gadgets and appreciate thoughtful design and performance.
Strong automation, high cleaning power, and quiet operation appeal to enthusiasts. However, the data doesn't highlight distinctive design aesthetics or passionate reviews about sensory experience…
You want a robot vacuum that works out of the box with minimal fiddling.
Mid-tier ease of setup and software suggests some configuration needed. The dual mopping attachment and automation features add complexity compared to basic models, making it less of a safe default.
You want a robot vacuum that cleans well but won't break the bank.
At ~$1210, it's a premium-tier price point. Cheaper rivals like the Roomba 694 (~$175) or 360 Vis Nav (~$350) cover the basics for a fraction of the cost, making this a poor fit for budget-conscious… Consider Roomba 694.

Frequently asked
What buyers want to know.
What is the Roborock S9 MaxV Ultra best at?
Reviewers say it delivers strong overall cleaning performance and excels at automated carpet cleaning with strong suction. The large internal water tank allows extended mopping between refills, and the mop pad lifts very high to keep carpets dry.
Does it have hair-tangling problems?
Yes. Reviewers note the dual roller brush system tangles easily with long hair around the axles, and the built-in hair-cutting system is not very effective at preventing this.
Who should buy this model?
It's best for buyers who want strong cleaning performance and a large water tank and don't mind an older chassis design. It's not a good fit for households with pets or long hair, since the roller system tangles easily.
How does it compare to newer models in the line?
