If you want a robot vacuum that can do much more than simply collect dust, the Roborock S8 Pro Ultra is a model worth considering.
This premium robot vacuum and mop was designed to automate many of the tasks that normally require your attention. It can vacuum floors, mop hard surfaces, empty its dustbin automatically, wash its mop, dry the mop, and refill its water supply through its multifunctional docking station.
That level of automation is the main reason the S8 Pro Ultra is different from cheaper robot vacuums.
Instead of buying a small robot that simply cleans your floor and then returns to a charging station, you get a complete cleaning system designed to reduce daily maintenance.
The S8 Pro Ultra also includes 6,000Pa suction power, LiDAR navigation, Reactive 3D obstacle avoidance, dual rubber brushes, sonic mopping, intelligent mop lifting, multi-floor mapping, app control, and smart-home compatibility.
But there is one important question:
Is the Roborock S8 Pro Ultra still worth buying today?
The answer depends heavily on the price you can get it for.
Because newer robot vacuums have entered the market, paying the original premium price may not always be the best decision. However, if you find the S8 Pro Ultra at a strong discount, its combination of automation and cleaning features can still make it an attractive option.
In this detailed review, we will look at everything you need to know before buying it, including the price range, specifications, cleaning performance, pros and cons, maintenance, and who should or should not buy it.
Roborock S8 Pro Ultra: Quick Verdict
Our overall impression: 8.2/10
The Roborock S8 Pro Ultra is a polished, highly automated robot vacuum and mop whose biggest strength is the RockDock Ultra — a single station that washes, dries, refills, and empties so you barely have to think about floor care.
Suction is strong, the dual rubber brushes are great for pet hair, sonic VibraRise mopping is a meaningful step above passive cloths, and LiDAR navigation is reliable.
However, the S8 Pro Ultra is no longer the newest generation of Roborock technology. Newer flagships have arrived with stronger suction, smarter obstacle avoidance, and more advanced edge cleaning. The 3.8/5 Amazon rating from 883 reviews is also worth taking seriously before you spend this much money.

What Is the Roborock S8 Pro Ultra?
The Roborock S8 Pro Ultra is a high-end robotic vacuum cleaner and mop.
Its main purpose is to reduce the amount of manual floor cleaning you need to do.
The robot can move around your home, map rooms, vacuum dirt, mop hard floors, detect obstacles, return to its dock, empty collected dust, wash its mop, dry the mop, and refill water.
This means the S8 Pro Ultra is not simply a robot vacuum.
It is closer to an automated floor-cleaning system.
That makes it particularly interesting for busy households, people with pets, families, and anyone who does not want to spend time vacuuming and mopping every day.

Roborock S8 Pro Ultra Price
The price is one of the most important things to consider before buying the S8 Pro Ultra.
This is a premium robot vacuum, and it was originally positioned at the high end of the robot vacuum market.
However, the price can change significantly depending on Amazon promotions, seller discounts, availability, and whether the product is sold new or through another listing.
Expected Price Range
A reasonable range to use when evaluating this product is approximately:
$700–$1,000
The S8 Pro Ultra becomes much more attractive when you find it near the lower end of that range.
For example, paying around $700–$800 can make the S8 Pro Ultra a much more interesting purchase than paying close to its original premium pricing.
If the price is approaching $1,000 or more, you should compare it with newer Roborock models and competing robot vacuums before buying.
Important: Amazon prices can change at any time. The price shown when you click the purchase button may be different from the price shown later.
6,000Pa Suction Power
One of the main specifications of the S8 Pro Ultra is its 6,000Pa suction power.
This provides strong cleaning power for everyday household dirt.
The robot can pick up common debris such as:
- Dust
- Crumbs
- Hair
- Pet hair
- Dirt
- Small particles
- Everyday floor debris
However, suction power is not the only factor that determines cleaning performance.
The brush design, navigation system, cleaning pattern, floor type, and airflow all affect the final result.
The S8 Pro Ultra combines its suction power with a dual rubber brush system.
This is particularly useful for homes with pets because hair can become tangled in traditional brush systems.
The rubber brushes are designed to help collect hair while reducing some of the problems associated with conventional bristle brushes.
Dual Rubber Brush System
The S8 Pro Ultra uses two rubber brushes that work together to collect dirt and debris.
This design can be useful on both hard floors and carpets.
One of the biggest advantages is pet hair.
If you have a dog or cat, hair can quickly accumulate around the house.
A robot vacuum that runs regularly can help keep that buildup under control.
However, no robot vacuum should be considered completely maintenance-free.
Hair can still accumulate around the brushes and other parts of the robot, so occasional manual maintenance is still necessary.
Sonic Mopping Technology
Vacuuming is only one part of the S8 Pro Ultra.
The robot also includes a sonic mopping system.
Instead of simply dragging a wet cloth across the floor, the mop vibrates against the surface to help loosen dirt.
This can be useful for removing everyday marks and stains from hard flooring.
The robot can help clean surfaces such as:
- Tile
- Hardwood
- Vinyl
- Laminate
- Other compatible hard floors
The mopping system is particularly useful for everyday maintenance.
If someone spills a drink, leaves footprints, or brings dirt into the house, regular automated mopping can help keep the floor cleaner between deeper cleaning sessions.
Intelligent Mop Lifting
One problem with robot mops is that wet mop pads should not be dragged across carpets.
The S8 Pro Ultra addresses this with intelligent mop lifting.
When the robot detects carpet, it can raise the mop.
This allows the robot to transition between hard floors and carpets without requiring you to manually remove the mop every time.
For homes with mixed flooring, this is a very useful feature.
RockDock Ultra: The Most Important Feature
The RockDock Ultra docking station is arguably the biggest reason to buy the S8 Pro Ultra.
Many robot vacuums can automatically return to a charging dock.
The S8 Pro Ultra goes much further.
The dock can perform several maintenance tasks automatically.
Automatic Dust Emptying
After the robot finishes cleaning, it can return to the dock and automatically empty its dustbin.
This means you do not need to manually empty the robot after every cleaning session.
For pet owners, this can be especially useful because the robot may collect large amounts of hair and debris.
Automatic Mop Washing
After mopping, the robot can return to the dock and wash its mop.
This eliminates one of the most annoying parts of owning a robot mop.
You do not have to remove the mop after every cleaning cycle and wash it manually.
Automatic Mop Drying
The dock can also dry the mop after washing it.
This helps keep the mop ready for the next cleaning cycle and can help reduce unpleasant smells caused by leaving a wet mop inside the dock.
Automatic Water Refilling
The system can refill the robot's water supply from the dock.
This further reduces the amount of maintenance you need to perform.
Together, these features make the RockDock Ultra a major advantage over simpler robot vacuums.
Reactive 3D Obstacle Avoidance
Robot vacuums need to deal with real homes, and real homes are rarely completely free of objects.
There may be:
- Shoes
- Toys
- Cables
- Pet toys
- Furniture
- Other objects
The S8 Pro Ultra uses Reactive 3D obstacle avoidance to help identify and avoid obstacles.
This can reduce the chance of the robot becoming stuck.
However, it does not mean the robot can recognize every object perfectly.
Before starting a cleaning cycle, it is still a good idea to remove loose cables, small objects, and anything that could interfere with the robot.
Battery Life
The S8 Pro Ultra offers up to approximately 180 minutes of battery life under suitable conditions.
Actual runtime can vary depending on:
- Suction level
- Floor type
- Cleaning mode
- Mopping
- Navigation
- Home size
If the robot needs more power, it can return to the dock to recharge.
For large homes, automatic recharge and continued cleaning can be very convenient.
Smart App Control & Smart Home
The S8 Pro Ultra can be controlled through a smartphone app.
You can use the app to manage different aspects of cleaning.
For example, you can:
- Start cleaning
- Stop cleaning
- Schedule cleaning
- Select rooms
- Select cleaning zones
- Create no-go zones
- Manage maps
- Adjust cleaning settings
- Monitor cleaning progress
This means you do not have to manually press a button every time you want the robot to clean.
You can schedule it to clean while you are away from home.
The S8 Pro Ultra also supports smart-home integration with platforms such as Amazon Echo and Google Home, allowing voice commands to start, stop, or pause cleaning depending on your smart-home setup.
Is the Roborock S8 Pro Ultra Good for Pet Hair?
Yes, it can be a good option for pet owners.
The dual rubber brush system is designed to help collect hair and debris while resisting tangling better than traditional bristle brushes.
The automatic dust emptying system is another major advantage.
If you have a dog or cat that sheds heavily, you can schedule regular cleaning so the robot collects hair before it builds up.
However, heavy pet owners should expect to perform occasional maintenance because hair can still accumulate around brushes and other components.
For everyday pet-hair maintenance, the combination of strong suction, rubber brushes, and an auto-empty dock makes the S8 Pro Ultra one of the stronger older-generation Roborock picks.

Who Should Buy the Roborock S8 Pro Ultra?
The S8 Pro Ultra is best for people who value automation.
You have pets
Pet hair can quickly cover floors. Automated cleaning can help keep your home under control.
You have a large house
The mapping, long runtime, and automated dock are particularly useful for larger homes.
You have hard floors and carpets
The vacuum and mop combination makes it versatile.
You want minimal daily cleaning
If you hate vacuuming and mopping every day, this is exactly the type of product designed to help.
You want automatic mop maintenance
The automatic washing and drying functions are major benefits.
You have a busy lifestyle
You can schedule cleaning and allow the robot to work while you are away.
You want smart-home integration
The ability to use an app and compatible smart-home systems adds convenience.
Who Should NOT Buy It?
The S8 Pro Ultra is not the best choice for everyone.
You may want another product if:
- You have a very small apartment — The large dock can take up valuable floor space.
- You have a limited budget — There are much cheaper robot vacuums available.
- You only need basic vacuuming — If you do not care about automatic mop washing, drying, dust emptying, or water refilling, you can save money with a simpler model.
- You want the newest technology — Newer flagship robot vacuums may offer more advanced features.
- You do not have much floor to clean — If your home is very small, the advanced automation may not justify the cost.
How Much Maintenance Does It Need?
One of the biggest misconceptions about premium robot vacuums is that they require zero maintenance.
The S8 Pro Ultra dramatically reduces maintenance, but it does not eliminate it.
You should still periodically:
- Clean sensors
- Check brushes
- Remove tangled hair
- Clean filters
- Empty or maintain water tanks
- Clean the docking station
- Check wheels
- Replace consumable parts when necessary
The advantage is that you do not have to perform these tasks every day.
Final Verdict: Should You Buy the Roborock S8 Pro Ultra?
The Roborock S8 Pro Ultra remains a powerful premium robot vacuum and mop.
Its combination of 6,000Pa suction, dual rubber brushes, sonic mopping, LiDAR navigation, Reactive 3D obstacle avoidance, automatic dust emptying, automatic mop washing, automatic mop drying, automatic water refilling, multi-floor mapping, and smart-home control makes it much more than a basic robot vacuum.
Its biggest strength is convenience.
Once properly configured, the robot can handle much of the routine floor cleaning without requiring you to constantly interact with it.
For busy households and pet owners, this can make a noticeable difference.
However, the S8 Pro Ultra is not automatically the best purchase at every price.
Its 3.8/5 rating from 883 reviews is worth considering, and newer robot vacuums may offer improved technology.
The best strategy is therefore to buy the S8 Pro Ultra when Amazon offers it at a substantial discount.
Our Recommendation
Recommended for: busy families, pet owners, larger homes, mixed flooring, and people who want maximum cleaning automation.
Not recommended for: small apartments, budget shoppers, people who only need basic vacuuming, and buyers who want the newest generation of robot vacuum technology.
Price Target
- Good Deal: $700–$800
- Fair Deal: $800–$900
- Consider Alternatives: $900–$1,000+
Because Amazon prices change frequently, check the current price before ordering.
Bottom line: If your main goal is to reduce the amount of work required to keep your floors clean, the Roborock S8 Pro Ultra has many of the features you want. It is powerful, highly automated, smart, and capable of both vacuuming and mopping. Buy it when the discount is strong — around $700–$800 it is a compelling premium robot vacuum for people who want hands-off cleaning. If the price is close to $1,000, take a little more time to compare newer alternatives before making the purchase.
Frequently Asked Questions
Quick answers to the most common questions about the Roborock S8 Pro Ultra — based on the official spec sheet, customer feedback, and how the robot performs in real homes.
Is the Roborock S8 Pro Ultra still worth buying?
It depends on the price. Around $700–$800 it is a very attractive premium robot vacuum and mop with strong automation (RockDock Ultra), 6,000Pa suction, sonic VibraRise mopping, LiDAR navigation, and dual rubber brushes that handle pet hair well. At $1,000 or more, you should compare it with newer Roborock and competitor flagships. The 3.8/5 Amazon rating from 883 reviews is also worth considering before buying.
Does the S8 Pro Ultra vacuum and mop at the same time?
Yes. It is a combined robot vacuum and mop with sonic VibraRise mopping that vibrates the mop pad against the floor to loosen dirt. It also features intelligent mop lifting, so when the robot detects carpet, it raises the mop to avoid dragging wet pads over carpet fibers.
What does the RockDock Ultra do?
The RockDock Ultra is the multifunctional docking station that ships with the S8 Pro Ultra. It can automatically empty the robot's dustbin, wash the mop after each cleaning run, dry the mop with hot air to prevent odor, and refill the robot's internal water tank. Together, these features dramatically reduce how often you need to interact with the robot.
Is the S8 Pro Ultra good for pet hair?
Yes, generally. The S8 Pro Ultra uses dual rubber brushes instead of traditional bristles, which resist hair tangling and work well for picking up dog and cat hair from hard floors and carpets. The auto-empty dock also helps because the collected hair is sucked out of the robot into a sealed dust bag. Very heavy-shedding homes should still expect occasional brush maintenance.
How long does the battery last?
Roborock advertises up to approximately 180 minutes of runtime under suitable conditions. Real-world runtime depends on suction level, mop usage, floor type, cleaning mode, and your home layout. The robot can return to the dock, recharge, and resume cleaning automatically, so large homes do not need to be cleaned in a single battery cycle.
Does it work on carpet and hard floors?
Yes. The S8 Pro Ultra is designed for mixed-floor homes. On hard floors it vacuums and sonic-mops in the same pass. When it detects carpet, intelligent mop lifting raises the mop pad to keep the carpet dry while the brushes and suction continue cleaning.
Does it work with Alexa and Google Home?
Yes. The S8 Pro Ultra supports Amazon Echo (Alexa) and Google Home voice control, in addition to the Roborock / Xiaomi Home smartphone app. You can start, stop, or pause cleaning, send the robot back to its dock, and check status with simple voice commands.
What is the Amazon ASIN?
The Amazon ASIN associated with the Roborock S8 Pro Ultra in this review is B0BVB5PTDK. Prices on that listing can change frequently, so always check the current price before ordering.
What is a good price for the S8 Pro Ultra?
For this older-generation premium model, approximately $700–$800 is a particularly attractive price. $800–$900 is still reasonable depending on condition and alternatives. Above $900, it becomes worth comparing newer Roborock and competitor flagships (such as the S8 MaxV series or current Dreame L-series) before buying.
Does it still need maintenance?
Yes. Despite the high level of dock automation, you will still need to refill clean water, empty dirty water, replace the dust bag, clean the dock washing tray, wipe sensors, check the dual rubber brushes for tangled hair, and replace the mop pad, side brush, and filter on a schedule. The exact frequency depends on your home, especially the number of pets and how often the robot runs.
