FAQ

What core features of the Saros 20 have been upgraded compared with the Saros 10R?

The Saros 20 introduces a series of major upgrades over the Saros 10R. Suction power has been increased to 36,000 Pa, while downward mop pressure has been enhanced to a maximum of 13 N. The upgraded AdaptiLift™ Chassis 3.0 lifting system significantly improves obstacle-crossing capability, allowing the robot to overcome double-layer thresholds up to 4.5 cm + 4.3 cm. Additional upgrades include dust bag drying, an increase in mop washing temperature to 100°C, expanded obstacle recognition capabilities, and the introduction of SmartPlan® 3.0. The exterior has also been upgraded with a brushed metal finish, improving both durability and premium feel.
How has the cleaning performance of the Saros 20 been improved?

The Saros 20 features a 36,000 Pa high-performance suction system, combined with the DuoDivide® main brush system and a 100% anti-tangle design, delivering powerful deep-cleaning performance on carpets. For mopping, it applies up to 13 N of downward pressure and supports 100°C hot-water mop washing, enabling more effective removal of stubborn stains. The FlexiArm side brush and extendable mop ensure thorough cleaning along edges and in corners.
Has the obstacle avoidance system of the Saros 20 been improved?

The Saros 20 retains its 3D ToF navigation system, using the StarSight Autonomous System at the front and the StarSight Navigation System at the rear-left, while receiving significant software-level enhancements through algorithm optimization. It can now identify over 300 types of obstacles, with notably improved lateral avoidance accuracy, ensuring smoother and more precise navigation in complex home environments.
What is SmartPlan® 3.0?

SmartPlan® 3.0 is Roborock's next-generation intelligent cleaning system with advanced planning features. It analyzes home layouts and user behavior patterns to automatically generate and execute personalized cleaning plans. The system supports multi-floor mapping, zone-based priority settings, and real-time adjustments via the Roborock app. Set it once, and the robot handles the rest.
What upgrades have been made to the Saros 20 docking station?

The Saros 20 multi-functional docking station supports 100°C hot-water mop washing, 55°C hot-air drying, automatic detergent dispensing, auto-emptying, automatic water refilling, and self-cleaning. A newly added dust-bag drying system helps prevent moisture buildup and odors, ensuring long-term hygiene and freshness throughout the entire cleaning system.
What are the design and manufacturing features of the Saros 20?

The Saros 20 features a unibody brushed-metal exterior, delivering a premium appearance while offering enhanced resistance to wear and scratches. Its 7.98 cm ultra-slim body allows it to easily clean under sofas, beds, and other low-clearance furniture. Combined with the AdaptiLift™ Chassis 3.0, the robot adapts seamlessly to both carpets and hard floors, significantly increasing overall cleaning coverage.
Does the Saros 20 support video calls and voice control?

Yes. The Saros 20 is equipped with a built-in RGB camera that supports video calling, allowing you to remotely check on your home at any time. It also features a built-in voice assistant, enabling hands-free voice control of cleaning functions for a more intuitive smart-home experience.
What improvements does the Saros 20 offer for carpet cleaning?

The Saros 20 features a Brush Stabilization Module that works in conjunction with the AdaptiLift™ Chassis 3.0 multi-stage lifting system. This combination keeps the main brush in a precisely controlled position, improving carpet-cleaning performance and significantly enhancing the pickup efficiency of larger debris.
How well does the robot handle thresholds? What types of thresholds can it pass over?

The Saros 20 supports a maximum threshold-crossing height of 8.8 cm, making it suitable for a wide range of home environments. It can easily cross single thresholds such as door sills up to 4.5 cm, as well as double-layer thresholds like balcony tracks combined with door sills up to 4.5 cm + 4.3 cm. This allows it to adapt smoothly to sliding doors and other complex floor transitions.

1.Based on internal testing by the manufacturer, under test conditions where the first threshold height does not exceed 4.5 cm, the gap depth between the two thresholds is greater than 12.0 cm and does not exceed 14.0 cm, and the second threshold height does not exceed 4.3 cm, the robot is capable of crossing double-layer thresholds with a combined height of up to 8.8 cm. Actual performance may vary depending on environmental conditions and actual user usage.

2.Based on available public information, Roborock's industry-first AdaptiLift™ 3.0 chassis (2024) enables this feature, which gained dynamic carpet cleaning in Q3 2025.

3.Based on internal testing by the manufacturer. Actual perforrmance may vary depending on environmental conditions. This function needs to be manually enabled in the Roborock app.

4.The body height of the robot vacuum is 7.98 cm. Due to slight vertical flexibility in the front structural components, the robot may achieve limited passive compression when entering low-clearance spaces, allowing access down to 7.95 cm. However, please note that scraping may occur. Actual performance may vary depending on environmental conditions.

Get one, you won’t regret it!!

Amazing machine! Bought for saving the job of vacuuming and mopping once a week but why wait? I’ve discovered you can have pristine floors and carpets all the time and it does a lot better job than me and I thought I was thorough! Lots of unexpected extras like the two way audio, video viewing, ‘Find My Pet’ and manual manoeuvring! If I’d known how awesome this machine was, I’d have had one sooner!!

Life changer

Being an early adaptor of robovacs (since 2021) and purchasing the Saros 20 as a replacement I was honestly blown away by how efficient and customisable this specific robovac is. Nearly the entirety of my ground floor is either LVT or Tiles and the vac and mop feature is fantastic. There are no streak marks left behind, the cleaning options offer a great deal of flexibility and the noise is minimal. The best recommendation or seal of approval is my wife has no complaints and she's now absolved me of my weekly vac and mop chores. Great result.

Fantastic does an amazing job So simple to set

Only 1 thing I would change if it came with a couple of vacuumed bags with a zip on the bottom. I managed to get 3 and they are great.

Early days but instantly impressive. Will help with cleaning following disability

Amazed how quick and easy and reliable it was to set up. I thought mapping would take ages, it was seconds. Looking forward to trying settings for a couple of weeks before I set up automatic routines. I was disappointed that the ‘set’ did not include floor cleaning solution. I was very excited to set up and use instantly but found I needed to buy their own solution. Not convenient having to wait further. Also I am still waiting for points on account to offset further purchase of solution and accessory pack. Waiting to hear back from support.

Works great

First robotic vacuum; works really well and very easy to use

Amazing product!

Fantastic upgrade on Saros10

Fantastic upgrade on Saros10.

The best purchase

The best purchase.I have three dyson, but this one it is in first place

I bought the most expensive model that just does not work

I bought the most expensive model, believing it was the best, and if there were any problems, a company like Robrock would have engineers who could resolve the issue instantly or replace the machine under consumer rights. No such luck; still waiting after 3 weeks.

Hi, thanks for reaching out. We apologize for the trouble with your robot. Please rest assured that our support team is currently working with you via email to resolve this issue. Should you require any additional help, please don't hesitate to reply to us directly. Best regards!

Don’t buy customer services difficult to contact and extremely slow

Very poor broke after 2days,don’t buy, still awaiting a replacement customer services extremely slow and helpful

Dear Customer, we are truly sorry for the trouble you’ve encountered. Our records show that our support team is currently assisting you with this matter. Please feel free to reply directly to our email if you need any additional help or have further questions. We are always here for you.

Think it is a great purchase

Think it is a great purchase. As we have three Labradors it covers around 200 sqm of hard flooring every evening for us. It saves us a lot of time. All I would say is make sure you do your bit with making sure it is kept clean

Roborock Saros 20 - Great Tech

Roborock Saros 20 is our first robot vacuum and mop. It’s great in terms of cleaning and suction power. It has got stuck a few times and we’ve had to add a few no go areas into the software. If I could I’d say 4.5, basically not quite perfect yet but a great product.
For the price I thought it might not really perform but it absolutely does, great product overall and with a few improvements in software it will be very hard to beat. I’d recommend it happily

Easy to set up and

Easy to set up and map

Ordered and paid 16 days ago. Still not received. No support number to call, no online chat facility. Slow communication by email. Still waiting for my product. Protracted courier investigation now initiated which could take another 14 days apparently. Not the kind of service tou expect when you buy a premium product.

Very disappointing product

I was so excited to get this but have been very disappointed. The mop mounts keep falling off. We are awaiting a returns label, without much success! This is not a good company when something has gone wrong! This is the problem of dealing with a Chinese company. I wish I'd bought it from Amazon.

Hello, we are very sorry that you are experiencing problems with your robot vacuum. We see that our support team is helping you with the issue. Should you require further assistance, please do not hesitate to contact us via the email directly.

Highly recommend this

Highly recommend this, it feels like a new member of family, a helpful maid AND a little pet at the same time. Love it

Very easy to set up and operate

Very easy to set up and operate, maps very well and cleans well, into corners and close to edges. Quiet in operation. Expensive, but worth it.

A Helpful addition but far from perfect.

Overall, I’ve been pleased with the robot hoover, especially the mopping function, which has made a noticeable difference on our wooden and tiled floors. It does a really good job of keeping these areas clean with minimal effort.

The vacuum performance has been a little disappointing, particularly on carpets, where it often leaves dirt and debris behind. I’ve also noticed that when it crosses thresholds, the movement can cause the bin to dislodge and spill some of the collected rubbish back onto the floor, meaning there is often extra cleaning needed afterwards.

For hard floors, the mop function is a real strength, but I expected better vacuum performance, especially on carpets and around transitions between rooms.

Excellent

Confused someone in middle of cleaning The name

Confused someone in middle of cleaning

The name is Rocky but the voice is women voice

APP is not much friendly better to select the room/rooms then select vacuum/mop/ both

Sometime miss some rooms during cleaning

Unbelievably good

Unbelievably good, AMAZING… you have changed my life! I can’t believe how happy this robot hoover has made me… I come down in the mornings to a clean fresh house, no dog hair, squeaky clean floors!!!

Its been okay! Dont think its worth the amount i paid but hayho! I feel for the price it could be better.

It cleans very well

It cleans very well. The only downside is that it doesn’t always want to go over high thresholds and doesn’t clean that particular room
