I imagine you‘re trying to decide between Roborock and Roomba robot vacuums. As someone who analyzes smart home gadgets to determine the best option for different needs, let me provide my in-depth perspective…
These two brands sit at the top of the robot vacuum market. While both Roborock and Roomba offer excellent floor cleaning performance leveraging advanced technology, key factors like navigation sensors, battery capacity, suction power, smart home connectivity and compatibility with hard floors can sway which model ultimately suits your home best.
In this comprehensive guide, we’ll unpack those differentiators across areas like mapping accuracy, runtime, carpet cleaning efficacy, app integration, maintenance demands and more while comparing specific models head-to-head. By the end, you‘ll have clear insights to pick if a Roomba or Roborock cleaner aligns closest with your priorities for convenience, cleaning ability and automation.
Let‘s dig in…
How Roborock and Roomba Navigate Your Floors
Any robot vacuum‘s cleaning consistency heavily relies on its navigation system to accurately map rooms while avoiding obstacles.
Roborock devices use a combination of laser distance sensors (LDS) and simultaneous localization and mapping (SLAM) algorithms. The LDS optical laser beams scan surroundings up to 6 meters away to determine room dimensions and object locations down to millimeter precision based on the time signals take to bounce back.
That digital floorplan then enables SLAM technology plot the most efficient cleaning path while confirming the robot‘s posed location as it moves. Premium Roborocks incorporate front-facing cameras as well for additional object recognition. Models can save multiple floor maps – handy when cleaning different rooms or levels regularly.
By contrasts, Roombas localize using iAdapt visual simultaneous location and mapping (vSLAM). Relying on an upward facing camera along with floor tracking sensors, vSLAM continually processes images of ceilings while creating an ongoing map of rooms and obstacles. Roombas also determine their position approximately every millisecond using integrated motion sensors.
This visual mapping data allows Roombas to navigate in orderly rows across floor areas. Certain Roomba models also provide "Imprint Smart Mapping" allowing you to label mapped rooms and target specific areas to clean.
Both approaches provide excellent navigation tailored to robot vacuums. But LDS laser scanning combined with SLAM generally enables Roborocks to map surroundings and plot courses even more precisely.
Suction Smackdown: How Roborock and Roomba Compare
Navigating flawlessly matters little if the vacuum lacks the raw suction power to lift debris, dirt and pet hair from carpets and hard floors.
Let’s examine the maximum suction power of Roborock and Roombas using the most telling metric – Pascals (Pa):
| Brand | Model | Max Suction (Pa) |
| Roborock | S7 MaxV Ultra | 5100 |
| Roborock | S7+ | 2500 |
| iRobot | s9+ | 40x |
| iRobot | i3+ | 10x |
As the figures show, Roborock‘s highest-end model beats even the most powerful Roomba available in raw suction – an impressive 5100 Pa. Mid-tier Roborocks like the S4 still reach 2000 Pa suction pressure.
That said, Roombas counterpunch relying less on brute suction force and more on overall cleaning system efficacy. Roomba utilizes a proprietary 3-Stage Cleaning System combining counter-rotating brushes, edge-sweeping brushes and adjustable vacuum intake for excellent pickup across floor types – especially deeper shag carpets.
So Roborock takes the trophy for most intense suck while Roomba may clean some surfaces more thoroughly thanks to clever brush systems and placement.
Onboard Batteries: Runtimes Head-to-Head
Additionally critical metric separates the bots – how long they run before requiring a mid-job recharge break. Check out battery capacities by charge:
| Brand | Model | Battery | Runtime |
| Roborock | S7 MaxV Ultra | 5200 mAh | 180 min |
| iRobot | s9+ | 3,950 mAh | 120 min * |
*Per April 2022 CNET review
As shown in the table above, not only do Roborocks integrate markedly larger batteries, but those cells translate to significantly longer cleaning times between charges – up to 180 minutes for the S7 MaxV Ultra.
The majority of Roombas average just 60-90 minutes before needing juice. That‘s usually enough for 1-2 average rooms. But Roborocks‘ 3+ hour runtimes let you clean multiple large areas or even entire levels of homes on one charge.
For anyone frustrated by frequent recharge breaks slowing down the cleaning process, Roborock bots provide vastly better battery endurance over Roombas to maintain cleaning momentum.
Smart Home Integration
Virtually all Roborocks and Roombas connect with popular smart home platforms via apps plus voice control:
Roborock
- Mi Home app (iOS & Android)
- Alexa & Google Assistant voice commands
Roomba
- iRobot HOME app (iOS & Android)
- Alexa & Google Assistant voice commands
Through the apps, you can start cleaning cycles, schedule vacuums, monitor progress, and designate specific room cleaning. Roombas perhaps provide slightly more metrics like dirt detection notifications.
But Roborocks enable greater customization like no-go zones you want to cordon off and the ability to save multiple floor plans.
Both integrate extremely well overall with major smart ecosystems and allow extensive (if not always necessary) remote control through well-designed apps. For most homeowners‘ needs, capabilities are likely on par.
The Game-Changing Convenience of Roborock‘s Mopping
Here‘s an exclusive trick up Roborock‘s sleeve – several models like the S7 double as robot mops, not just vacuum cleaners.
Using built-in water tanks, sonic vibration and microfiber cloths, compatible Roborocks can simultaneously vacuum and mop hard floor surfaces like wood, tile and vinyl. The high frequency vibration scrubs stubborn dried spills while suction eliminates lifted grime.
This 2-in-1 design provides outstanding convenience for homes with a healthy mix of hardwoods and carpets, eliminating the need to breakout a separate manual or steam mop. It also simplifies scheduling – you can clean all floors in one autonomous job.
Roomba does not sell integrated mopping models currently. So Roborock offers a true uniqueness proposition for the cleaning versatility enabled by its mop/vac hybrid approach.
Price Comparison: Good, Better & Best Models
With insight into those key performance metrics and features, how do prices shake out between Roomba and Roborock across good/better/best budget tiers?
| Good 😃 | Better 😎 | Best 🤩 | |
| Roborock | S4 Pure ($280) | S5 Max ($420) | S7 Max Ultra ($1,000) |
| Roomba | i3+ ($350) | s9 ($650) | i7+ ($900) |
A few takeways:
- Roborocks provide more advanced mapping/navigation capabilities even at lower price points
- You need to step up higher in Roomba‘s range to get premium features
- But Roombas counter with greater carpet cleaning optimization
Around the $300-600 mid-tier, expect very comparable results. At the highest end, Roborocks like the S7 Max Ultra provide more next-gen advantages but cost more than top Roombas.
Let‘s now move onto ideal real-world applications given those pros and cons.
Ideal Use Cases
Based on the robot vacuum advantages I detailed for Roborock versus Roomba, here are home situations I typically recommend each for:
Roborock Works Best If You Have:
- Large or multi-story houses given long battery runtimes
- Lots of hard floors suitable for Roborock‘s mopping abilities
- Tight budgets but still want quality mapping/navigation & high suction
Roomba Works Best If You Have:
- Mostly carpets and rugs where Roomba‘s brushes excel
- Apartments/small homes fitting Roomba‘s 60-90 min charge
- Pets like dogs/cats thanks to Roomba’s carpet optimization
- Existing Amazon/Google smart home ecosystem to leverage voice controls
As I‘m sure you can relate to, home layouts and needs vary widely. Carefully matching the robot vacuum‘s strengths to your floors, rooms, obstacles and smart capabilities ensures the best experience.
The Bottom Line
While both provide outstanding autonomous cleaning leveraging advanced technology, Roborock models generally edge out Roombas in crucial areas like:
- Runtime thanks to substantially bigger batteries
- Navigation and mapping precision courtesy of LDS sensors
- Integrated mopping with certain Roborock models – a true gamechanger for hard floors
But Roomba remains tough to top for no-fuss vacuuming if you primarily have carpets and small-medium spaces.
I hope mapping out those subtle differences assists to determine if a Roborock or Roomba aligns best to meet your needs and home layout. Both companies make exceptional robot vacuum cleaners. Identifying the ideal match comes down to the precise cleaning scenarios and features offering the greatest convenience for your living environment.
