Introduction
The Dreame L10s Ultra Gen 2 represents a 2024 flagship model equipped with a comprehensive multifunction base, whilst the Roborock Q7 L5+ or BF+ Plus arrives in 2025 as a more streamlined option focused primarily on vacuuming with auto-emptying capabilities. These two models occupy different positions within the robot vacuum landscape, which becomes evident when examining their technical specifications and cleaning approaches.
The Dreame model targets users seeking a complete hands-free cleaning solution with both vacuuming and mopping handled automatically. The Roborock alternative appeals to those prioritising reliable vacuuming performance with self-emptying convenience, without the added complexity of automated mopping systems.
Power and Suction
Suction power clearly favours the Dreame L10s Ultra Gen 2, which generates 10,000 Pa compared to the 8,000 Pa produced by the Roborock Q7 L5+ or BF+ Plus. This 2,000 Pa difference translates into noticeably stronger pickup, particularly beneficial for homes with carpets or pets that shed heavily.
The brush configurations differ as well. The Dreame employs a simple brush design, whilst the Roborock relies on a bristle brush. Neither model features anti-tangle technology in the main brush, meaning households with long hair may need to perform regular maintenance on both units. The side brushes on each model remain fixed without extension or elevation capabilities, and neither incorporates anti-tangle features for the side brush either.
What matters in practice is that the higher suction of the Dreame provides a performance cushion for deep cleaning tasks, though the Roborock's 8,000 Pa still handles everyday debris competently across hard floors and low-pile carpets.
Mopping
The mopping systems reveal the most significant divide between these two robots. The Dreame L10s Ultra Gen 2 utilises dual rotating mops with extension capability and a movement system that helps reach edges more effectively. These mops lift 10.5 mm when carpets are detected, preventing unwanted dampness on soft surfaces.
The Roborock Q7 L5+ or BF+ Plus features a static mop without any lifting mechanism. This means the mop remains in contact with all surfaces during operation, making it unsuitable for homes with mixed flooring unless you manually remove the mop pad before cleaning carpeted areas.
Crucially, the Dreame base washes the mops with cold water during and after cleaning, then dries them using hot air to prevent odours and bacterial growth. The Roborock base provides no mop washing or drying functionality whatsoever. For anyone serious about maintaining genuinely clean floors rather than simply spreading dirty water around, this distinction matters enormously. The Dreame also includes a detergent dispenser to enhance cleaning results, another feature completely absent from the Roborock.
Neither model offers automatic mop removal at the base, dirt detection in mops or on floors, nor heated water for floor cleaning. Both use cold water for their mopping operations.
Navigation System
Both robots employ LiDAR navigation via a 3D laser turret, ensuring accurate mapping and efficient route planning. However, the Dreame L10s Ultra Gen 2 supplements this with a frontal 3D laser sensor that enables obstacle avoidance, whilst the Roborock Q7 L5+ or BF+ Plus lacks this additional sensing capability.
The Dreame specifically recognises pets, allowing it to navigate more carefully around animals. The Roborock provides no object recognition features. Neither model includes an AI camera, LED lighting for night vision, or remote camera access. The Dreame does incorporate CleanGenius AI for intelligent cleaning adaptation, a feature not present in the Roborock.
In homes with varied obstacles, children's toys, or pets, the Dreame's enhanced sensing provides tangible benefits by reducing the likelihood of collisions or getting stuck.
Autonomy and Battery
Battery specifications show a substantial advantage for the Dreame L10s Ultra Gen 2, which houses a 5,200 mAh cell delivering 240 minutes of runtime. The Roborock Q7 L5+ or BF+ Plus contains a 3,200 mAh battery with no specified runtime duration.
This extended autonomy proves particularly valuable in larger properties where a single cleaning session might otherwise require mid-clean recharging. Both robots can climb obstacles up to 20 mm high, handling standard door thresholds and low-pile carpet edges without difficulty.
Intelligent Features
Neither the Dreame L10s Ultra Gen 2 nor the Roborock Q7 L5+ or BF+ Plus incorporates a robotic arm. Both models support external voice assistants including Alexa and Google Home, allowing voice control integration within existing smart home ecosystems.
The Dreame's CleanGenius AI functionality adjusts cleaning parameters based on detected conditions, whilst the Roborock operates with more conventional programming without adaptive intelligence.
Multifunction Cleaning Base
Both models provide automatic dust bin emptying into base-mounted bags. The Dreame base holds a 3.2-litre dust bag compared to the 2.7-litre capacity in the Roborock base, meaning slightly less frequent bag replacements.
The fundamental difference lies in mopping support. The Dreame L10s Ultra Gen 2 base washes mops with cold water and dries them using hot air, maintaining mop hygiene automatically. It also stores 4.5 litres of clean water and 4 litres of dirty water, with a detergent dispenser for enhanced cleaning. A plumbing connection kit is available as a separate purchase for those wanting to eliminate manual water management entirely.
The Roborock base offers none of these mopping support features. It functions purely as an auto-empty station without water tanks, mop washing, or drying capabilities. Neither base includes automatic tray cleaning or UV disinfection.
Dimensions
The robot bodies measure similarly, with the Dreame L10s Ultra Gen 2 at 350 mm diameter and 97 mm height, whilst the Roborock Q7 L5+ or BF+ Plus spans 325 mm diameter and 99 mm height. The Dreame's slightly lower profile may help it access beneath certain furniture pieces more easily, though the 2 mm difference proves marginal in real-world use.
Base dimensions differ dramatically. The Dreame base measures 340 mm wide, 590.5 mm tall, and 456.7 mm deep—a substantial footprint reflecting its multifunction capabilities. The Roborock base is considerably more compact at 212 mm wide, 259 mm tall, and 178 mm deep, occupying far less floor space but offering correspondingly fewer features.
Anyone with limited space needs to consider whether the Dreame's larger base justifies the mopping automation it provides, or whether the Roborock's compact station better suits their available area.
Real-World Usage Experience
The Dreame L10s Ultra Gen 2 suits larger homes thanks to its 240-minute runtime and 5,200 mAh battery, comfortably handling extensive floor areas without recharging interruptions. Its 10,000 Pa suction and pet recognition make it particularly appropriate for households with shedding animals. The comprehensive mopping system with automatic washing and drying delivers genuinely hands-free floor maintenance across hard surfaces.
The Roborock Q7 L5+ or BF+ Plus works well in smaller properties where the 3,200 mAh battery proves sufficient. Its 8,000 Pa suction handles everyday debris effectively, and the compact base fits more easily into tight spaces. However, the static mop without washing or drying requires manual intervention and limits its appeal for anyone wanting fully automated mopping.
For mixed flooring with both hard surfaces and carpets, the Dreame's mop lifting prevents dampening rugs inadvertently, whilst the Roborock requires manual mop removal before vacuuming carpeted areas. Neither model offers particular advantages for specific floor types beyond these mopping considerations.
Conclusion: Which Should You Choose?
Choose the Dreame L10s Ultra Gen 2 if: you want comprehensive automation covering both vacuuming and mopping without manual intervention. It suits larger homes thanks to extended battery life, and works particularly well for pet owners needing stronger suction and intelligent obstacle navigation. The multifunction base justifies its footprint if you value genuinely automated floor washing rather than basic wiping.
Choose the Roborock Q7 L5+ or BF+ Plus if: you prioritise vacuuming performance with auto-emptying convenience in a compact package. It makes sense for smaller properties where space is limited and mopping automation isn't essential. The simpler system may also appeal to those preferring straightforward operation without the complexity of water tank management and mop maintenance systems.
The decision ultimately hinges on whether automated mopping with washing and drying justifies the Dreame's higher investment and larger base footprint, or whether the Roborock's focused vacuuming approach with space-saving design better matches your cleaning priorities and available space.
