Roborock Saros 20: what you get, and what you still do

What does it cost, and who sells it?

$1,599.99 on Roborock’s US store on Nov 14, 2026, the same as on Oct 20.

Roborock shows no sale on it: its “compare at” price is the same $1,599.99. Roborock calls it “a 2026 flagship robot vacuum cleaner”.

Next to the price, Roborock promises free shipping, returns “for any reason in 30 days of delivery”, a one-year limited warranty and 24/7 support. Its return terms add that “all accessories and the original packaging are required for any returns and refunds”, and that “A penalty may be imposed if any accessories are missing.” So keep the box for the first month.

Other sellers

Amazon has a Saros 20 listing sold by Roborock (checked Oct 31, 2026). As with every Amazon listing, we show a Check price button, not a price. Roborock’s “Where to Buy” list names 16 sellers, its own store among them, including Best Buy, Home Depot, Target and Walmart. Those links go to Roborock’s brand pages, not to this model, and we haven’t checked those four for the Saros 20 yet.

What does the dock do?

In Roborock’s words, it “supports 212 °F hot-water mop washing, 131 °F warm-air drying, automatic detergent dispensing, auto-emptying, automatic water refilling, and self-cleaning.”

It works from tanks: a clean-water tank you fill and a dirty-water tank you empty. Roborock doesn’t mention a plumbing kit for the Saros 20 on its product page or in its manual, so as far as Roborock’s pages say, it can’t be connected to your water supply.

In the box: the robot, the dock and its base, a power cable, the rotating mop module, one dust bag, one mop pad and the user manual.

What do I still have to do?

Clean the brushes and filter every two weeks, and replace the mop cloths, side brush, main brushes and filter on Roborock’s schedule.

Roborock Saros 20 FCC User Manual, Routine Maintenance. Read Nov 14, 2026.

The manual doesn’t say how long a dust bag lasts, and Roborock doesn’t give the bag’s capacity. One practical line from the manual: “Always install a dust bag before putting back the dust container cover to avoid auto-emptying without the bag.”

What do replacement parts cost?

Mop cloths are $39.99 for four on Roborock’s US store, the only part listed for the Saros 20 by name.

Not ranked. Roborock’s US store, its own listings only, before tax. Checked Nov 14, 2026.

We don’t add these up into a yearly cost. Roborock gives replacement ranges, not one figure, and how often you replace parts depends on your home.

What about cleaning solution?

Only Roborock’s own, if you use any.

The manual says to “only use cleaning solution recommended by Roborock”. Among its safety lines: “To Reduce the Risk of Fire and Electric Shock due to internal component damage, use only roborock cleaning solution intended for use with this appliance.” Roborock’s warranty also leaves out damage caused by “cleaning solutions not manufactured or explicitly approved by Roborock”.

You don’t have to use any. The manual says: “If no floor cleaning solution is used daily, you may skip this step or disable Smart Cleaning Solution Filling in the app.” Roborock publishes its solution’s ingredients and safety data sheet.

Which floors can it handle?

Door sills up to 1.77 in, carpet pile up to 1.18 in once you turn that on in the app, and furniture as low as 3.14 in, in Roborock’s words.

Roborock, Saros 20 product page, checked Nov 14, 2026. Saros 20 FCC User Manual, read Nov 14, 2026.

Neither page says where “high pile” starts, so we show the carpet lines side by side rather than call them a conflict. Roborock doesn’t state the battery’s runtime or the robot’s noise; the battery is “6,400 mAh Lithium-Ion”.

Does it need the app, an account or a subscription?

No subscription is mentioned anywhere we looked. The app does most of the work; two buttons do the basics.

• SubscriptionNot mentioned

  Roborock’s app page, the Saros 20’s page and its user agreement name no price or paid plan. Roborock app page

• Security updatesAt least 2 years

  Roborock promises “software security updates for robotic vacuum cleaners for a minimum of 2 years”, counted from no later than the day it went on sale on Roborock’s site. Security support policy

• The serviceCan change

  Roborock’s user agreement says it “may change, suspend, restrict, terminate or revoke the rights of our services at any time without notice”. User agreement

Without the app: two buttons on the robot start a clean and, with the robot on its dock, empty the bin or wash the mop cloths. Any button pauses it. The manual doesn’t say what else works without the app or the internet.

Turning Wi-Fi off: the manual says to “press the Reset button until you hear a voice message. Then wait for 5 minutes and the WiFi will be automatically deactivated.” The Reset button is under the magnetic top cover and a rubber plug.

Voice and smart home: a built-in “Hello Rocky” voice assistant, and “Matter Protocol Compatible (Siri Shortcuts / Alexa / Google Home)”, in Roborock’s words.

It has a camera. What does Roborock say about images and data?

The Saros 20 has “a built-in RGB camera that supports video calling, allowing you to remotely check on your home at any time.”

Roborock’s Trust Center describes how its robots handle images, video and voice. It speaks of all its models, not the Saros 20 by name.

• Obstacle photosKept on the robot

  “saved on the robot in an encrypted format”; when you view one in the app, “The cloud acts only as a temporary communication channel and does not store the image.”

• Video callsPassword first

  Each needs “a gesture password in the app”, is end-to-end encrypted, and “Once the call ends, the real-time video stream is immediately cleared”.

• VoiceDepends on the model

  “Most models process voice commands entirely offline”; “select online models” send encrypted voice to the cloud. Roborock doesn’t say which group the Saros 20 is in.

• Where data is keptBy region

  “in data centers based on your registered region”. To see what your robot collects, Roborock says to open the app, choose the robot, then Settings, then Product Information.

Roborock’s website privacy policy, last updated Feb 27, 2025, lists data centers “in China, Germany and the United States”. That policy covers Roborock’s websites and store; the app has its own policy, shown in the app, which we haven’t read. The Trust Center says each product’s certifications are on its product page; the Saros 20’s page lists none.

What does the US warranty cover?

One year, from Roborock, for robots sold in the US by Roborock or its “authorized resellers, authorized distributors”.

The year starts on the day you buy it (in California, the day it’s delivered). Without a receipt, it starts three months after the robot left the factory.

1. 1Email RoborockClaims go to [email protected].
2. 2Roborock choosesRepair, a “new or refurbished unit”, or a refund of the price.
3. 3Cover carries onA repaired or replaced robot is covered for 90 days or the rest of the year, whichever is longer.

Not covered, among others: “Consumable components of the Product, such as brushes”; normal wear and cosmetic damage; damage from parts or cleaning solutions Roborock hasn’t approved; “failure to perform routine maintenance”. The warranty is void if the robot is “purchased, used, or operated outside the United States of America.”

Extended warranty: Roborock sells these only on its own store, only when you order the robot. It calls one “a service contract, not an insurance product”, and it ends if you sell the robot. No extended-warranty option appeared on the Saros 20’s page when we checked; Roborock’s terms say that means none is offered for that product.

Safety, in Roborock’s words

From the Saros 20 FCC User Manual.

• “Do not allow to be used as a toy. Close attention is necessary when used by or near children.”
• “Do not put any low objects (such as shoes, mats) near raised areas like stairs. Otherwise, the robot may fall down caused by malfunctional sensors.”
• “To prevent the robot from falling or causing injury, make sure there are no height drops (such as cliffs or steps) near the threshold, and ensure the surrounding area is safe.”
• “Keep hair, loose clothing, fingers, and all body parts of people and pets away from seams, openings and moving parts of the product to avoid possible injury.”
• “To prevent water damage, make sure that the floor where the robot operates is free of water.”
• “Caution, hot surface. Do not touch the clean water dispensers or drying air outlets.”

What we can’t answer yet

Roborock doesn’t say, or we haven’t been able to read its answer.

1. How long does the battery run on a charge, and what does a new one cost? Roborock lists neither.
2. How long will the app support the Saros 20 beyond the two-year security-update minimum?
3. Are its voice commands handled on the robot or in the cloud?
4. What does the app’s own privacy policy say?
5. Which “Saros Series” parts fit the Saros 20?
