Ultimate Roborock Breakdown: 2025 Buyer Guide

If you’re overwhelmed by Roborock’s sprawling lineup, you’re not alone. This guide distills the key differences among each series—Q, S, Qrevo, and Saros—so you can decide which features are worth paying extra for and which you can skip. From budget-friendly models to premium robots with cutting-edge capabilities, we’ll help you focus on the must-know points and find a Roborock that fits both your home and your wallet.

This guide cuts through the noise to get to the real differences users will experience with the Roborock lineup, so it will attempt to simplify the details for a broader understanding of how Roborock organizes its lineup. However, we will also include our detailed tables of all of the official specs from Roborock for you to go deeper into the numbers. And, as always, you can refer to our in-depth reviews, which will be linked throughout this guide, for more information on the Roborock robots that we have reviewed.

How to Navigate This Guide

This guide starts at the entry level series and the lowest priced models within that series and explains the key differences between the models as features are added, enhanced, or replaced. You can start with the lower tier models within each series and go up from there, so you can find the most affordable option to meet your requirements.

We didn’t post the prices in the body of the guide, as these change frequently with sales and mark-downs, but we did use the MSRP list price from Roborock to determine the order for the product list.

Price-First Shopping

If low price is your primary metric, look to the Q Series first, as these models tend to be the most affordable. Jump to Q

Entry-level models in the S line can also fit tighter budgets, while higher-level models will include more premium features (and higher price tags.) Jump to S

The Qrevo series starts in the mid-range for pricing and goes up to premium as they include greater innovations in automation and navigation technology. Jump to Qrevo

The Saros series is Roborock’s newest premium lineup, carrying cutting-edge innovations that also come with premium price tags. Jump to Saros

Feature-First Shopping

As a general rule, features increase with price. Entry-level models may lack advanced mopping or navigation enhancements, while premium robots can wash and dry their mopheads automatically, detect obstacles more accurately, or even integrate with a home’s plumbing for hassle-free refills.

If features are more important to you than price, focus on the features descriptions and upgrade maps to see where your preferences appear in the lineup. Remember that premium models have more features, and that this guide is arranged by price from lowest to highest.

Roborock Commonalities

Every model in Roborock’s lineup, regardless of series, includes app control, an adaptive route algorithm, and third-party voice control integration. This means even the most budget-friendly Roborock offers intelligent navigation paths, scheduling, and the option for basic voice commands.

Overview: Q Series

The Q Series is Roborock’s most budget-friendly lineup. While these models don’t offer premium features like auto mop washing or high-end obstacle avoidance, they do provide laser-based navigation, reliable suction (ranging from 4200 Pa to 5500 Pa), and the option of auto-empty dustbins in their docks (indicated by a “+”). Most Q robots have basic mopping attachments, making this series ideal for buyers who want core functionality without extras.

Q Series Features

All Q models rely on LDS (laser) navigation for systematic cleaning, with some additions in specific models.

Q models carry a 5200mAh battery, with an official runtime of 240 minutes on quieter settings—except for Q7 variants, which are rated at 180 minutes. Coverage typically spans 300 sqm, although the Q5 Pro officially covers up to 350 sqm.

The presence of a “+” in any model name (e.g., Q5 Pro+, Q7 Max+) indicates an auto-empty dock, which is the only docking automation in the Q Series. No Q model dock includes mop-cleaning or tank-refilling capabilities.

Most of the Q models feature a simple, fixed mop, with the exception of the Q5 Max+, which has no mop pad at all. It is not a combo vacuum/mopping robot, so if you only want a Roborock robot vacuum at the lowest price you can get it, the Roborock Q5 Max+ (Amazon Link) is the model is for you.

Q Series Mopping

All other Q robots feature a simple, fixed mop. This pad must be attached or removed manually and washed by hand. It does not lift over carpets and it has no scrubbing action: it is a wet pad that the robot pulls behind it on the floor. There are more advanced mopping features in other Roborock series, but this is a simple, economical way to get your floors vacuumed and mopped.

Q Series Navigation and Obstacle Avoidance

The entire Q lineup uses LDS lasers (LiDAR) to map and navigate your home. This means they create an internal map of your house and determine the best routes to take to maximize battery life, go around and under furniture, and avoid stairs.

Obstacle Avoidance is different from navigation. Obstacle avoidance is the robot’s ability to recognize and go around items in its path, like socks, phone chargers, or the dreaded pet waste. This is not standard on all Q models, so if obstacle avoidance is important to you, you need to go with the Q8 Max or Q8 Max+. The Q8 Max uses Roborock’s Reactive Tech obstacle avoidance.

Q series Brushes

The Q series uses two kinds of main brushes, the DuoRoller and the Single Rubber. DuoRoller brushes are two brushes that spin counter to one another to maximize suction and minimize hair tangles. The Single Rubber brush is what it sounds like: a single brush with rubber instead of bristles, as bristles have been known to worsen hair wrap.

All Q models have a fixed side brush, meaning it does not extend or retract.

Q Dock Features

The Q series has two options for a dock: a simple charging station, or a dock with auto-empty dustbin, which sucks the debris from the robot’s onboard dustbin and stores it in a bag in the dock. Any Q model with a “+” in the name will have an auto-emptying dustbin in the dock.

Q series Suction Ratings

Most Q Models have a suction rating of 5,500Pa, with the exception of the Q7 Max, which has a suction of 4,200Pa, possibly as a result of its single rubber brush.

Q series Threshold limits

Q models can handle thresholds up to 20mm.

Q Series Models

Despite what looks like a large lineup, there are only four base Q robot models: the Q5 Max, the Q5 Pro, the Q7 Max, and the Q8 Max. Models with the “+” added to their name come with a dock that automatically empties the robot’s dustbin instead of a simple charging dock. The Roborock Q lineup can be summarized as follows:

• Q5 Max+ is strictly vacuum-only, featuring 5500 Pa suction and a DuoRoller brush. It has LDS navigation and app controls.
• Q5 Pro / Q5 Pro+ is an upgrade to the Q5 Max in that it introduces a simple fixed mop pad.
• Q7 Max / Q7 Max+ uses a single rubber brush with 4200 Pa suction and a shorter listed runtime of 180 minutes. Advanced navigation software sets it apart from Q5 variants.
• Q8 Max / Q8 Max+ increases suction to 5500 Pa and uses larger bins, a DuoRoller for more power, and a longer runtime. The Q8 Max also is the only Q with obstacle avoidance with the addition of Reactive Tech, which suggests No-Go Zones and goes around obstacles on the floor so you don’t have to tidy up as much before the robot cleans

Overview: S Series

S8 vacuums occupy a mid-to-premium space, blending high suction, automatic mop lifting, and sonic mopping to handle a range of flooring with minimal user intervention.

S Series Features

Roborock’s current S series robots all include a DuoRoller main brush and a vibrating mop pad that lifts itself when vacuuming carpets, preventing accidental wetting of rugs and dramatically increasing mop automation.

A robust navigation system—consisting of laser sensors, obstacle avoidance, and carpet sensing—further enhance performance.

The battery is standardized at 5200mAh with a rated runtime of 180 minutes.

Most models stand about 96.5mm tall, aside from the MaxV variant, reaching 103mm.

S Series Mopping

All models in the S series use a mop pad that vibrates for scrubbing action and lifts over carpets. The technology for this pad is called VibraRise (for both vibrating and rising) and there are three generations in the S Series.

VibraRise 1.0	VibraRise 2.0	VibraRise 3.0
One-point vibration, 3000 vibrations/minute, 5mm lift	Two-point vibration, 3000 vibrations/minute, 5mm lift	Two-point vibration, 4000 vibrations/minute, 20mm lift
Models: S8/S8+	Models: S8 Pro Ultra	Models: S8 Max Ultra, S8 MaxV Ultra

For added coverage, the S8 MaxV Ultra (Amazon Link) has an Extra Edge Mop – a second, mini mop pad – on the side of the robot body for better cleaning at the edges of the room.

S Series Navigation and Obstacle Avoidance

The entire S lineup uses LDS lasers (LiDAR) to map and navigate your home. Navigation is how robot vacuums create an internal map of your house and determine the best routes to take to maximize battery life when they go around and under furniture and avoid stairs.

Obstacle Avoidance is different from navigation. Obstacle avoidance is the robot’s ability to recognize and go around items in its path, like socks, phone chargers, or the dreaded pet waste. This is standard on all S models, but different models use different technologies.

• Reactive 3D uses 3D structured light and infrared imaging, and appears on most S8 models.
• Reactive AI (generation 2.0 in the S8 series) uses 3D structured light in combination with an RGB camera to identify objects and move around them. Roborock has also made use of the RGB camera for enhanced Pet Features. If you have heard about Roborock vacuums taking picture of your pets, finding your pets when you are away from home, or turning down their main brush when avoiding your pets, this is the feature they were talking about.

S series Brushes

The S series uses two kinds of main brushes, the DuoRoller and the DuoRoller Riser.

DuoRoller brushes are two brushes that spin counter to one another to maximize suction and minimize hair tangles.

DuoRoller Riser brushes, new in the S8 series, are the same as the original DuoRollers except they also rise when the robot senses high pile carpets, to prevent pulling in the fibers of the carpet and possibly stalling the machine.

FlexiArm side brushes extend further to clean in corners. These are more common in higher tiered models.

Fixed side brushes do not extend or retract.

S Dock Features

The S series has four options for a dock, depending on the model:

• a simple charging station (S8)
• a dock with auto-empty dustbin (S8+), which sucks the debris from the robot’s onboard dustbin and stores it in a bag in the dock, denoted by the “+” as in the Q series
• a RockDock with an auto-emptying dustbin, a mop washing and drying station, and auto-refilling tank with other features. The user periodically refills the clean water tank and empties the dirty water tank. This option signaled by the word “Ultra” in the name (S8 Pro Ultra, S8 Max Ultra, S8 MaxV Ultra)
• a Refill and Drainage System which has a lot of the same features as the RockDock, but with the addition of integrating into your houses plumbing system for full mopping automation (no naming clues, available in variations of S8 Max Ultra and S8 MaxV Ultra)

Charger Only	Auto Empty Dustbin	RockDock “Ultra” Dock	Ultra Dock with Integrated Plumbing Option Available
S8	S8+	S8 Pro Ultra, S8 Max Ultra, S8 MaxV Ultra	S8 Max Ultra, S8 MaxV Ultra

S series Suction Ratings

Suction ratings are not always a reliable measure of a robot vacuum’s actual performance, but they do indicate more sophisticated technologies and premium features. The S8 series ranges from 6000Pa to 10000Pa.

Model (With Amazon Links)	Suction
S8 S8+ S8 Pro Ultra	6000Pa
S8 Max Ultra	8000Pa
S8 MaxV Ultra	10000Pa

S series Threshold limits

S models can handle thresholds up to 20mm.

S Series Models

• S8 and S8+ introduce a vibrating mop pad that lifts over carpets, allowing the robot to vacuum carpets and mop hard floors in the same run. The standard S8 comes with the robot and a basic charging station, while the S8+ pairs that same robot with an auto-empty dustbin in the dock.
• S8 Pro Ultra introduces a more advanced dock that automatically refills the water tank, washes and dries the mop pad, and empties the robot’s dustbin. This unit also lifts its main brush, giving high pile carpets more room. 
• S8 Max Ultra has the same features as the S Pro Ultra with the addition of Intelligent Dirt Detection, auto detergent dispensing, an integrated plumbing option as well as 8000Pa of suction.
• S8 MaxV Ultra added an extending side brush and extra edge mop system as well as an RGB Camera for advanced object recognition and pet features as well as 10000Pa of suction.

Overview: Qrevo Series

The Qrevo Series is Roborock’s answer to those seeking fully automated mopping—complete with washing, drying, and tank refilling in their specialized docks. These mop-cleaning features come standard with every robot in the Qrevo series, as well as auto-empty dustbins, which does away with the “+” and “Ultra” naming conventions of the earlier series. They have a mid-level tier and a premium tier, with their most premium models frequenting the top of our Best Robot Vacuums List.

Qrevo Series Features

All Qrevo vacuums include dual spinning mopheads that lift away from carpets, preventing accidental wetting of rugs.

Their specialized docks manage both auto-emptying of the dustbin and mop maintenance, drastically cutting down on user intervention.

Entry-level variants use a single rubber brush and lack some upgrades to the dock and robot body, while higher-level Qrevos introduce DuoRoller or DuoDivide brush systems, higher suction levels, and innovative obstacle recognition and avoidance.

Qrevo Series Mopping

The hallmark feature in the Qrevo series uses Dual Spinning Mop Pads that lift out of the way when the robot senses carpets.

A nice feature that you will see in higher-level Qrevo models is an extending mophead for edge and corner mopping. This takes the FlexiArm technology that Roborock used first in side brushes on the S series and applies it to the Qrevo mopping system.

Qrevo Series Navigation and Obstacle Avoidance

For Navigation, the Qrevo line uses LDS lasers (LiDAR) to map your home (with one exception – see below). This means they create an internal map of your house and determine the best routes to take to maximize battery life, go around and under furniture, and avoid stairs. LiDAR is mounted on the top of the robot, which brings the profile of the robot up slightly to accommodate the LiDAR.

Obstacle Avoidance is different from navigation. Obstacle avoidance is the robot’s ability to recognize and go around items in its path, like socks, phone chargers, or the dreaded pet waste. Obstacle Avoidance is standard on all Qrevo models, but different models use different technologies.

• Reactive Tech was first introduced on the Q8 Max, and reappears in the Qrevo series. It is a more entry-level obstacle navigation that uses sensors and algorithms to detect and avoid obstacles in its path.
• Reactive AI uses 3D structured light in combination with an RGB camera to identify and avoid objects as low to the ground as 3cm and as wide as 5cm. Roborock has also made use of the RGB camera for enhanced Pet Features. If you have heard about Roborock vacuums taking picture of your pets, finding your pets when you are away from home, or turning down the power on their main brush when avoiding your pets, this is the feature they were talking about.

Qrevo series Brushes

The Qrevo series uses three kinds of main brushes: the single rubber, the DuoRoller Riser, and the new DuoDivide.

• The Single Rubber brush is what it sounds like – one rubber brush without bristles, as bristles worsen hair wrap.
• DuoRoller Riser brushes, first seen in the S8 series, are the same as the original DuoRollers except they also rise when the robot senses high pile carpets to prevent pulling in the fibers of the carpet and stalling the machine.
• DuoDivide brushes, new in the Qrevo series, are available on the premium Qrevos. They are two small brushes with a space between them so that hair can slip through without wrapping around the brush. This design is extremely effective at avoiding tangles.

The lower tiered models have a fixed side brush, meaning it does not extend or retract, while the premium tiers have an extending side brush, called FlexiArm, to clean in corners.

Qrevo Dock Features

The Qrevo series has simplified options for docking. Docks with automatic mop cleaning and drying, auto-empty dustbins, and auto-refilling tanks are standard with Qrevo robot vacuums, doing away with the “+” and “Ultra” naming conventions.

The more premium robots do get some docking perks, however.

• Lower tier Qrevos wash the mops and dry the pads with warm air.
• Higher tier Qrevos wash their mop pads with hot water and feature Intelligent Dirt Detection – which can detect excessive dirt in the water and triggers a rewash of both the mops and the floor – and Automatic Detergent Dispensing

Mop Washing and Drying, Auto Empty Dustbins	Hot Water Mop Washing, Intelligent Dirt Detection/Automatic Detergent Dispensing
Qrevo Qrevo S Qrevo Plus	Qrevo Pro Qrevo MaxV Qrevo Slim Qrevo Master Qrevo Curv Qrevo Edge

These are Amazon links. As an Amazon Affiliate, we earn a commission if you make a purchase, at no additional cost to you.

Qrevo series Suction Ratings

Suction ratings are not always a reliable measure of a robot vacuum’s actual performance, but they do indicate more sophisticated technologies, premium features, and raw power. The Qrevo series ranges from 5500Pa to 18500Pa.

Model	Suction
Qrevo	5500Pa
Qrevo S Qrevo Plus Qrevo Pro Qrevo MaxV	7000Pa
Qrevo Master	10000Pa
Qrevo Slim	11000Pa
Qrevo Curv Qrevo Edge	18500Pa

These are Amazon links. As an Amazon Affiliate, we earn a commission if you make a purchase, at no additional cost to you.

QREvo series Threshold limits

Q models can handle thresholds up to 20mm until the innovations of the Curv and the Edge, where the thresholds can go up to 40mm if they are tiered.

Qrevo Models

• Qrevo (Amazon Link)
  • Baseline with dual spinning mops, 5500 Pa suction, and a single rubber main brush.
• Qrevo S (Amazon Link)
  • Baseline variant with dual spinning mops, 7000 Pa suction, and a single rubber main brush.
• Qrevo Plus (Amazon Link)
  • Adds a FlexiArm mophead, improving edge and corner cleaning.
• Qrevo Pro (Amazon Link)
  • Introduces enhanced dock features (Intelligent Dirt Detection, Hot water mop cleaning, automated detergent dispensing)
• Qrevo MaxV (Amazon Link)
  • Introduces an RGB camera to the lineup for more robust obstacle avoidance and pet features
  • Intelligent Voice Assistance for hands-free control.

Here, there is a feature jump. These models make notable leaps in functionality compared to the entry tier:

• Qrevo Slim (Amazon Link)
  • Upgrades to 11,000 Pa suction and a DuoRoller brush system for better agitation.
  • Slim Profile: Replaces the top-mounted LDS laser with 3D ToF navigation, reducing overall height.
  • Adds a lifting main brush and an extending side brush—both new to the Qrevo line.
• Qrevo Master (Amazon Link)
  • Similar features to Slim but returns to LDS for navigation (hence a taller body).
  • Suction is slightly lower (10,000 Pa) compared to the Slim’s 11,000 Pa, but overall performance remains high-end.
• Qrevo Edge (Amazon Link) (sub-variant: S5A)
  • 6400mAh battery, covering up to 400 sqm with a 240-minute runtime—best in Qrevo.
  • Introduces DuoDivide anti-tangle roller brushes, highly effective against hair wraps.
  • Introduces threshold crossing of 4cm, over the usual 2cm threshold limit. 
  • The main Edge model has an RGB camera for pet and obstacle recognition. 
  • The sub-variant is without the camera, the main brush lifting, or the voice assist features.
• Qrevo Curv (Amazon Link) (sub-variants: S5X, 5XC, 5A1)
  • Mostly mirrors Qrevo Edge in core functionality but with a rounded “dice-shaped” dock
  • Multiple sub-variants differ slightly in battery size, brush lifting, and voice assistance, often with smaller batteries than the main Curv, resulting in shorter runtimes.

Qrevo Series Upgrade Map

Refer to this table to see the pricing order of the Qrevo series, starting with its base model, and going up the line to see what is added or changed as the lineup moves up the pricing scale. Note that there is a significant feature jump starting at the Qrevo Slim.

Overview: Saros Series

Finally, the Saros Series represents Roborock’s next leap into hands-off automation, with only three models so far – all of them in the premium price range: Saros 10, Saros 10R, and Saros Z70. Each raises the bar beyond even the high-tier Qrevo and S8 robots, featuring detaching mop pads, retracting LiDAR, and, in the case of the Saros Z70, a robotic arm for moving small obstacles out of its path.

We earn a commission if you make a purchase, at no additional cost to you.

Saros Series Features

All models in the Saros series will purportedly have a profile height of 79.8mm, which is Roborock’s slimmest yet.

The battery is standardized at 6400mAh (higher than Roborock’s usual of 5200mAh) with a rated runtime at or over 180 minutes.

Saros Series Mopping

There are two mop types in the Saros Series: The latest generation of VibraRise 4.0 with the mini edger mop head (first seen in the S series), and the spinning mop pads of the Qrevo series with the extending mop head.

VibraRise 4.0 and Mini Edge Mop	Dual Spinning Mop Pads with Extending Mop Head
Two-point vibration, 4000 vibrations/minute, 18mm lift, detaches into the dock when not in use	Two spinning pads that lift 22mm for carpet, FlexiArm extending mophead
Models: Saros 10	Models: Saros 10R, Saros Z70

These are Amazon links. As an Amazon Affiliate, we earn a commission if you make a purchase, at no additional cost to you.

Saros Series Navigation and Obstacle Avoidance

There are two Navigation systems, depending on the model:

• A top-mounted LDS laser sensor (LiDAR) that can retract from its top-mounted position to bring the profile of the robot down for low clearances. The LiDAR can continue functioning through a wide window in the front until the clearance raises again.
• The next generation of StarSight 2.0. StarSight 2.0 builds on the original StarSight’s 3D ToF approach by introducing vertical structured light alongside its existing dual-light system. It projects a structured pattern—often invisible to the human eye—onto walls and furniture, then measures how that pattern distorts. This added vertical information allows the vacuum to construct a more detailed 3D map of taller or narrower obstacles that a single-plane sensor might overlook. This system has no top-mounted LiDAR.

Obstacle Avoidance is different from navigation. Obstacle avoidance is the robot’s ability to recognize and go around items in its path, like socks, phone chargers, or the dreaded pet waste. In the case of the Saros series, the Vertical Structured Light that is used in the navigation also serves as the obstacle avoidance technology.

Saros series Brushes

The Saros Series uses the DuoDivide brush system, first seen in premium Qrevo models. This design is made up of two brushes side by side with a space between them to prevent hair from wrapping around the brush. We have found this to be an effective design in our tests.

The Saros series introduces the FlexiArm Riser anti-tangle side brush, which not only extends to reach into corners, but also retracts away when not in use to prevent collisions and unnecessary use of the brush.

Saros Dock Features

The Saros series has complete utility in their docks. If Roborock offers it, the Saros dock has it. The features on the dock include:

• Hot water mop cleaning
• Hot water dock self-cleaning
• Intelligent Dirt Detection
• Auto Mop Removal
• Auto Detergent Dispenser
• Auto Tank Re-filling
• Auto Dust Emptying
• Warm Air Drying
• 2.5 hour fast charging

There is also an option to purchase a dock with integrated house plumbing with the Saros 10 and 10R models, but not on the Saros Z70 as of this writing.

Saros series Suction Ratings

Suction ratings on the Saros series reach all-time highs in their official specs:

Model	Suction
Saros 10 Saros Z70	22000Pa
Saros 10R	19000Pa

These are Amazon links. As an Amazon Affiliate, we earn a commission if you make a purchase, at no additional cost to you.

Saros Threshold Crossing

The Saros series will use the new Roborock AdaptiLift technology first seen in the Qrevo Edge and Curv to cross single thresholds of 30mm and tiered thresholds of 40mm.

Saros Series Models

The Saros series is still young at the time of this writing, with the Saros 10 and Saros 10R scheduled for release in February 2025 and the Saros Z70 for later in the year. These are the only three models that have been announced, and they do not seem to differ much in terms of premium versus entry level. They do use different technologies, however. The major difference among these models will naturally be the industry-first robotic arm on the Saros Z70.

• Saros 10 (Amazon Link)
  • Retracting LiDAR for slim 79.8mm profile
  • Vertical structured light for obstacle avoidance
  • Complete docking features with option for plumbing integration
  • 22000Pa suction
• Saros 10R (Amazon Link)
  • StarSight 2.0 navigation
  • No top-mounted LiDAR, 79.8mm profile
  • Vertical structured light obstacle avoidance
  • Complete docking features with option for plumbing integration
  • 19000Pa suction
• Saros Z70
  • StarSight 2.0 navigation
  • No top-mounted LiDAR, 79.8mm profile
  • Vertical structured light obstacle avoidance
  • Complete docking features
  • 22000Pa suction
  • Industry-first Robot Arm

Closing Thoughts

From the budget-minded Q Series to the ultra-premium Saros lineup, Roborock offers a broad range of robot vacuums tailored to different homes and priorities. If you simply want reliable cleaning on a smaller budget, the Q models suffice. For mixed floors and those wanting more automation, the S8 lineup adds a self-lifting mop and optional dock features that reduce hands-on maintenance. The Qrevo series amps up mopping capabilities and suction potential, while Saros introduces the next generation of autonomous cleaning—pushing innovation with retracting sensors, robotic arms, and self-detaching mop pads. Whichever way you choose, understanding the differences in each tier helps you pick a robot vacuum that balances cost, convenience, and performance.
