Updated August 2024
Robotic vacuums have come a long way from being simple cleaning gadgets to becoming integral parts of smart homes, offering advanced features that make everyday life easier. The Dreame L20 Ultra and the Roborock S7 MaxV Ultra represent the pinnacle of this evolution, boasting impressive specifications, intelligent navigation, and multifunctional capabilities. While both models are designed to deliver top-notch cleaning performance, they cater to slightly different needs and preferences. In this comparison, we’ll explore how these two models differ in terms of price, design, vacuuming and mopping efficiency, app functionality, built-in camera utility, additional features, and battery life to help you decide which one fits your lifestyle best.
Key Takeaways
The Dreame L20 Ultra, with its formidable 7000Pa suction power and 6,400mAh battery, offers robust cleaning performance and extended run time, ideal for larger homes. Its MopExtend™ Edge-Cleaning feature ensures even the tightest corners are spotless, complemented by a smart AI for obstacle avoidance and advanced connectivity through the Dreamehome app. On the other hand, the Roborock S7 MaxV Ultra, though slightly less powerful at 5100Pa, excels with its innovative sonic vibration mopping, ReactiveAI 2.0 for superior obstacle detection, and a sophisticated Empty Wash Fill dock, which minimizes manual maintenance. The S7 MaxV Ultra’s 5,200mAh battery still delivers up to 3 hours of cleaning, backed by recharge-and-resume functionality and seamless integration with the Roborock app, making it a formidable contender in any smart home setup.

#1 Price & Design
Dreame L20 Ultra
When it comes to price, the Dreame L20 Ultra and the Roborock S7 MaxV Ultra are both premium options, with the Dreame model priced at $1,499.99 and the Roborock slightly more affordable at $1,399. Both vacuums come with substantial base stations, but the Dreame’s is notably larger, standing at 60.7 cm tall, 42.6 cm wide, and 49.9 cm deep, compared to the Roborock's 16.6 x 19.8 x 16.5 inches.
The Dreame L20 Ultra features a sleek design with a 350ml dustbin, a 4.5-liter water tank, and retractable mops, while the Roborock S7 MaxV Ultra includes a 400ml dustbin and a 200ml water tank, with a semi-circular mopping pad. Although the Roborock's low-profile lidar sensor makes it slightly shorter at 3.8 inches, allowing it to navigate under more furniture, the Dreame L20 Ultra compensates with its sturdy design, highlighted by its tri-pronged side brush, dual mops, and front-facing lights. Both robots include lidar scanners and multiple control buttons on top, making operation straightforward. While the Dreame's aesthetic is more modern with its microphone for status updates, the Roborock focuses on functional design, albeit with a less visually appealing exterior.
#2 Vacuuming and Mopping Performance
Roborock S7 Maxv Ultra
In terms of performance, the Dreame L20 Ultra and the Roborock S7 MaxV Ultra offer top-tier cleaning capabilities, but each has its strengths. The Dreame boasts an impressive 7000Pa suction power, ensuring thorough dirt pickup across various surfaces, while the Roborock follows closely with 5100Pa, which is enhanced by its auto-adjusting suction when transitioning to carpets. The Dreame's dual mop pads provide a "squeaky-clean" finish, bolstered by its ability to raise the mops up to 10.5mm when detecting carpeted areas, while the Roborock employs sonic vibration technology, scrubbing at 3,000 times per minute to effectively remove stubborn stains. The Dreame's mops are also blow-dried with warm air after cleaning to prevent mildew, a feature not present in the Roborock. However, the Roborock's auto-lifting mop is particularly useful for mixed flooring environments, while the Dreame excels with its MopExtend™ Edge-Cleaning feature that tackles nooks and crannies effectively. Both models perform admirably in vacuuming, but the Dreame's higher suction power gives it a slight edge in overall dirt and debris removal.
#3 Companion App & Capabilities
Dreame L20 Ultra
Both the Dreame L20 Ultra and the Roborock S7 MaxV Ultra come equipped with robust companion apps that enhance the user experience through smart controls and customization. The Dreamehome app, compatible with iOS and Android, allows users to set up various cleaning modes, monitor the vacuum’s status, and even activate the camera for remote viewing. Meanwhile, the Roborock app is known for its simplicity and reliability, offering seamless WiFi connectivity and integration with Alexa and Google Assistant.

Dreame's app also provides a detailed post-cleaning report, showing the cleaning route, identified obstacles, and a history of cleanings. Roborock's app, however, takes smart mapping to the next level with 2D, 3D, and matrix map views, enabling users to split their homes into different rooms and zones, optimizing the cleaning process. While both apps offer high levels of control, Dreame's AI-driven mapping and obstacle detection give it an edge in adaptability, though Roborock's detailed room mapping and cleaning schedules are equally compelling for users who want to fine-tune their cleaning strategy.
#4 Built-in Camera
Dreame L20 Ultra
The inclusion of built-in cameras on both the Dreame L20 Ultra and the Roborock S7 MaxV Ultra adds a layer of versatility and functionality, particularly for those who appreciate smart home integration. Dreame’s camera can be activated through the app, allowing for a live feed of its cleaning path, which is useful for monitoring the vacuum’s progress or checking on your home while you’re away. The Roborock S7 MaxV Ultra goes a step further with its ReactiveAI 2.0 Obstacle Avoidance System, which utilizes an onboard camera, light, and AI chip to navigate around objects and even function as a two-way talk surveillance system. This means the Roborock not only avoids obstacles more efficiently but also adds an extra layer of home security, offering a dual-purpose feature that Dreame's camera does not.
#5 Additional Features
Roborock S7 Maxv Ultra
Additional features are where both the Dreame L20 Ultra and Roborock S7 MaxV Ultra truly shine, each bringing a unique set of capabilities to the table. The Dreame L20 Ultra is packed with advanced features like the MopExtend™ Edge-Cleaning, which excels in cleaning tight corners and edges, and its Deep Clean mode, which tackles tough stains with ease. Its smart AI for obstacle avoidance ensures a smooth cleaning experience, and the dust bag’s 75-day capacity minimizes the need for frequent maintenance.
On the flip side, the Roborock S7 MaxV Ultra impresses with its Empty Wash Fill dock, which not only self-empties and refills but also cleans the mopping pads, reducing manual intervention to a minimum. Additionally, the Roborock’s sonic vibration mopping and dual rubber brush design enhance its ability to scrub and pick up debris effectively. While Dreame’s warm air drying of the mops is a thoughtful touch, Roborock’s complete self-maintenance setup, including its self-cleaning mop pads and auto-lifting mop, offers a more hands-off approach.
#6 Battery Life and Connectivity
Dreame L20 Ultra
Battery life and connectivity are critical factors in choosing a robotic vacuum, and both the Dreame L20 Ultra and Roborock S7 MaxV Ultra deliver commendable performance in these areas. The Dreame L20 Ultra is equipped with a massive 6,400mAh battery, allowing for up to 180 minutes of cleaning time, making it ideal for larger homes. The Roborock S7 MaxV Ultra, while slightly behind with a 5,200mAh battery, still offers an impressive 3-hour runtime, with the added benefit of a recharge-and-resume feature that ensures it can finish the job even if it needs to pause for a recharge.
In terms of connectivity, Dreame supports Apple’s Siri, Amazon’s Alexa, and Google Assistant, making it versatile for various smart home setups. Similarly, Roborock is compatible with Alexa and Google Assistant, but its integration with the Roborock app’s smart mapping and scheduling features makes it exceptionally user-friendly. While Dreame’s larger battery might appeal to those needing extended cleaning sessions, Roborock’s efficient use of battery life and connectivity features ensures it remains competitive, particularly for users who value seamless operation within their smart home ecosystem.
