❓ Frequently Asked Questions
Which robot vacuum is better for pet hair?
The Roborock Qrevo S is the better choice for pet hair thanks to its higher suction power of 18,000 Pa compared to the Narwal Flow 2's 8,200 Pa. It will pick up more shedding in a single pass, especially on carpet.
Does the Narwal Flow 2 mop automatically?
Yes, the Narwal Flow 2 has an auto-cleaning dock that scrubs and rinses the mopping pads after every cleaning run, so you never have to touch dirty water. The Qrevo S requires manual water refills and tank emptying, making its mopping less convenient.
Which robot vacuum is quieter?
The Narwal Flow 2 is quieter at 67 decibels compared to the Roborock Qrevo S at 75 decibels. That 8-decibel difference is noticeable in real life, making the Flow 2 better for work-from-home situations.
Is the Qrevo S good for hard floors?
Yes, the Qrevo S handles hard floors well and is a generalist that works on any floor type. However, if mopping is important to you, the Narwal Flow 2 is the better choice since its auto-cleaning dock makes mopping actually convenient.
Which app is easier to use?
The Narwal Flow 2's app is simpler and more intuitive, focusing on essential features like starting cleans and scheduling. The Roborock Qrevo S app has more customization options with no-go zones and granular suction control, but it can feel overwhelming for basic use.
Which robot vacuum should I buy if I have mostly hard floors?
The Narwal Flow 2 is the no-brainer choice for hard floors since it combines vacuuming with automatic mopping, and the dock handles all the wet-cleaning work. If you also have significant carpet or pets, the Qrevo S might be worth considering for its stronger suction.

So you're thinking about getting a robot vacuum—maybe you've heard one humming around a friend's house, or you're just tired of pushing a regular vacuum up and down your hallway. You've narrowed it down to two seriously popular models: the Narwal Flow 2 and the Roborock Qrevo S. But here's the thing: they're actually built for different kinds of homes. One is obsessed with making your floors sparkle *and* shine, while the other is a generalist that handles whatever flooring chaos you throw at it. So which one belongs in your home?
The Narwal Flow 2 is for anyone who's sick of mopping—it's basically a robot that cleans your hard floors while also vacuuming, and its dock does the cleanup so you never touch dirty water. The Roborock Qrevo S is for people who want one really dependable vacuum that handles carpet, tile, and everything in between, without the mopping bells and whistles.
In this post, we'll walk through how they clean, how they navigate your home, what their apps are like, how loud they are, and how much bang for your buck you're getting. By the end, you'll know exactly which one fits your life.
Narwal is a Chinese robotics company that's become famous for innovative mopping docks that do the wet-cleaning work for you—they're usually priced in the $700–$900 range and skew toward people with hard floors. Roborock is the bigger, more established name in robot vacuums (owned by the same parent company as Dreame), with models ranging from budget-friendly to premium, and they're known for rock-solid navigation and reliability on any floor type. Both are well-reviewed, both have solid warranties, and both will happily work in most homes.
Mopping: The Narwal's Secret Superpower
The Narwal Flow 2 doesn't just mop—it has an auto-cleaning dock that scrubs and rinses the mopping pads after every cleaning run, like a tiny car wash for your robot. The Qrevo S has a mopping option, but it's honestly an afterthought; you'll need to refill water manually and empty the dirty water tank yourself, which defeats the purpose of owning a robot. If mopping is non-negotiable for you and you have mostly hard floors, the Flow 2 is a no-brainer.
Vacuuming Power: Both Are Strong, Different Strengths
The Qrevo S has higher suction power (18,000 Pa, which is a measurement of air pressure—think of it like how hard the vacuum is "pulling" dirt up) and genuinely excels on carpet, especially if you have pet hair or heavy debris. The Flow 2 is no slouch (8,200 Pa), but it's designed with the assumption you're mostly dealing with hard floors and light carpet. On deep carpet or if you have shedding pets, the Qrevo S will pick up more dirt in one pass.
Navigation: Both Use Smart Mapping, Flow 2 Is Slicker
Both robots use LiDAR (a laser scanner that maps your room like a bat using echolocation) to figure out where they are and what's in their way. The Flow 2's app is slightly more intuitive and the robot seems snappier about avoiding obstacles—in real homes, it just feels less "confused" in tight spaces. The Qrevo S is equally capable but its app has more buttons and menus, which can feel overwhelming if you just want to press "clean" and walk away.
Noise Level: Flow 2 Wins by a Whisper
The Narwal Flow 2 runs at about 67 decibels (roughly the sound of a normal conversation), while the Qrevo S is closer to 75 decibels—which doesn't sound like much, but in real life, that 8-decibel difference means the Qrevo sounds noticeably louder, especially if you're home while it's cleaning. If you work from home or have a light sleeper in the house, the Flow 2 is the less intrusive choice.
The App & Smart Features: Qrevo Has More Options, Flow 2 Is Simpler
The Roborock app lets you set up no-go zones (areas the robot won't enter), schedule cleanings, and tweak suction levels with granular control. The Narwal app is simpler and focuses on what matters—starting the clean, checking the map, and setting a schedule—but it doesn't overwhelm you with options. If you like tinkering with your tech, Qrevo wins. If you prefer to set it and forget it, Flow 2 is less fussy.
Value: Flow 2 for Mopping Fans, Qrevo S for Versatile Floors
The Flow 2 (around $799) is worth every penny if you have hard floors and hate mopping. The Qrevo S (around $749) is slightly cheaper and better for homes with mixed flooring—carpet, tile, and wood all together. Neither is a budget option, but both deliver excellent quality. If you're choosing purely on price with no mopping needs, Qrevo S edges ahead; if mopping matters, Flow 2 is the investment.
So, which one should you buy?
Here's the honest truth: these two robots are solving different problems. The Narwal Flow 2 is built for hard-floor homes where mopping is the chore you want to eliminate—its auto-cleaning dock is genuinely clever and saves you from ever touching dirty water. The Roborock Qrevo S is the all-rounder that handles carpet and hard floors with equal confidence and doesn't pretend to be a mopping wizard. Neither is "better" in an absolute sense; it's about matching the robot to your home's layout and your cleaning pet peeves.
Your gut feeling matters here. If you walked through your house and thought "I'd pay good money to never mop again," the Flow 2 is your answer. If you looked at your mix of carpet, tile, and hardwood and thought "I just need something that handles it all," the Qrevo S is the one. Both will work reliably for years, both have solid support, and both will give you back the weekend hours you used to spend cleaning. You can't go wrong—just go with what solves *your* problem.
