DREAME L40s Ultra AE Robot Vacuum and Mop White 19 vs Roborock 2026 New Qrevo S Pro Robot Vacuum and Mop

Suction Power and Cleaning Performance

The DREAME L40s Ultra AE offers a slightly stronger suction at 19,000Pa compared to the Roborock 2026 New Qrevo S Pro’s 18,500Pa. This means the DREAME model has an edge in picking up both tiny dust particles and larger debris, such as oatmeal or pet food, from various surfaces. Its powerful suction is especially effective on carpets, where it also excels at embedded pet hair removal.

Meanwhile, the Roborock Qrevo S Pro maintains robust suction suitable for everyday cleaning, effectively lifting dust, crumbs, cat litter, and pet hair. While its suction is marginally lower, it still performs well on hard floors and carpets, supporting a thorough clean. Both models are designed for pet-friendly homes, but the DREAME’s stronger 19,000Pa suction may provide an advantage in tackling tougher messes and deep carpet cleaning.

Brush Systems and Hair Management

The DREAME L40s Ultra AE employs a dual-brush system featuring a liftable rubber brush and a TriCut brush designed to cut through long hair and prevent tangling. This combination allows it to adapt to different cleaning scenarios, from floor gaps to carpets, reducing maintenance due to hair wrap.

In comparison, the Roborock Qrevo S Pro features an anti-tangle system with a zero-tangle side brush and an all-rubber main brush. It also includes an omnidirectional wheel designed to simplify maintenance by reducing hair wrap. Both models clearly prioritise pet hair management and ease of upkeep, but the DREAME’s TriCut brush offers a unique cutting function that may better handle longer hair, while the Roborock relies on anti-tangle design to minimise hair buildup.

Mop Technology and Maintenance

Both robotic vacuums provide advanced mopping capabilities with self-cleaning features, but their approaches differ. The DREAME L40s Ultra AE uses MopExtend technology, allowing it to glide around furniture legs, floor gaps, and edges for wider coverage. Its dock, the all-in-1 PowerDock, boasts a fully automated post-cleaning system that auto-empties dust for up to 100 days, dries mops with hot air, cleans the washboard, and uses 75°C hot water to wash mop pads, tackling tough stains and grease without manual intervention.

The Roborock Qrevo S Pro also features an upgraded dock with hands-free cleaning. It empties dust into a sealed 2.7L bag lasting 7–9 weeks and uses 167℉ (75℃) high-temperature self-cleaning to refresh mops after each use. Additionally, it employs 113℉ (45℃) warm air drying to keep mops ready for the next clean. While both docks automate maintenance, the DREAME’s 100-day dust auto-empty capacity exceeds the Roborock’s 7–9 week bag life, potentially reducing how often users need to manage waste.

Obstacle Avoidance and Navigation

Both robots incorporate smart obstacle avoidance, but with some distinctions. The DREAME L40s Ultra AE is powered by a Smart 3DAdaptObstacle Avoidance system that can detect and avoid up to 120 types of objects, including shoes, cables, and socks, reducing the risk of bumps or getting stuck. This system supports confident navigation around complex home environments.

The Roborock Qrevo S Pro uses smart obstacle detection to avoid common household items such as shoes, toys, and furniture legs. It also features a low-profile design at 3.8 inches, enabling it to clean under beds and sofas where dust often accumulates. While both models offer precise navigation, the DREAME’s system highlights a higher number of detectable obstacles, which may translate to fewer interruptions during cleaning.

Carpet Cleaning and Customisation

Both robotic vacuums offer tailored carpet cleaning strategies but with different features. The DREAME L40s Ultra AE allows users to opt for carpet avoidance to protect yoga mats or play mats, boost suction on carpets, enable intensive double-pass carpet cleaning, or prevent wetting of low-pile carpets by lifting the mop up to 10.5mm. This flexibility supports a customised approach based on carpet type and user preferences.

The Roborock Qrevo S Pro similarly adapts to carpet types with boosted suction and a 10mm mop-lifting feature to protect carpet fibres. It also provides customised cleaning modes for different rooms, adjusting settings automatically with AI-powered Roborock SmartPlan 2.0 based on floor types and cleaning history. The Roborock’s AI integration offers dynamic optimisation, while the DREAME provides more manual control over specific carpet-related functions.

Docking Stations and Waste Management

The docking systems of both models enhance hands-free operation but vary in capacity and functionality. The DREAME L40s Ultra AE’s PowerDock auto-empties dust for up to 100 days, dries mop pads with hot air, and cleans the washboard using 75°C hot water. This comprehensive dock aims for fully automated post-cleaning care, minimising user maintenance.

Conversely, the Roborock Qrevo S Pro’s upgraded dock empties dust into a sealed 2.7L bag designed to last 7 to 9 weeks and refreshes mop heads with 75°C self-cleaning and 45°C warm air drying. While effective, the Roborock’s dust collection interval is shorter, requiring more frequent attention. Both docks significantly reduce manual cleaning but the DREAME’s extended dust capacity offers a more convenient solution for less frequent emptying.

Price and Value

The DREAME L40s Ultra AE is priced at C$880.94, making it the more affordable option compared to the Roborock 2026 New Qrevo S Pro, which is listed at C$999.99. This price difference of roughly C$119 suggests that the DREAME provides strong value, especially considering its higher suction power, longer dustbin emptying interval, and advanced brush system.

That said, the Roborock offers AI-powered cleaning optimisation and a slightly more compact design, which some users might find valuable for specific home layouts. Both models cater well to pet owners and busy households, but the DREAME’s lower price combined with its advanced cleaning and maintenance features may appeal more to budget-conscious shoppers seeking powerful performance.

Which should you buy?

Choosing between the DREAME L40s Ultra AE and the Roborock 2026 New Qrevo S Pro depends on priorities like suction strength, maintenance convenience, and smart features. The DREAME stands out with its stronger 19,000Pa suction, longer dust auto-empty interval of up to 100 days, and unique TriCut brush designed for tangling prevention. Its all-in-1 PowerDock offers a highly automated post-cleaning experience that reduces user upkeep significantly.

The Roborock Qrevo S Pro, while slightly more expensive at C$999.99, excels with AI-powered cleaning plans that customise settings room-by-room and a low-profile design for better under-furniture reach. Its dock also provides hands-free maintenance but requires more frequent dust bag changes every 7 to 9 weeks.

For users prioritising maximum suction, extended maintenance intervals, and a lower price, the DREAME L40s Ultra AE is the better choice. Those seeking intelligent AI-driven cleaning and a compact profile might prefer the Roborock Qrevo S Pro despite its higher cost and slightly lower suction. Both models are excellent for pet owners and busy households, so the final decision should consider which features align best with your home and cleaning habits.
