Introduction
The Dreame L10s Ultra Gen 2 and Dreame L10s Ultra Gen 3 represent two consecutive generations within the same product line, separated by roughly a year. The Gen 2 launched in 2024, whilst the Gen 3 arrived in November 2025. Both are high-end robotic vacuum cleaners with multifunction bases capable of washing and drying mops, making them suitable for homes looking for a comprehensive cleaning solution that handles both vacuuming and mopping with minimal manual intervention.
These models target users who want automated floor care without constantly emptying dust bins or wringing out dirty mops. The presence of a multifunction base means the robot returns periodically to clean its mops during mopping sessions, ensuring floors get scrubbed with fresh pads rather than spreading dirt around.
Differences at a Glance
- Suction power: 10,000 Pa versus 25,000 Pa
- Extendable side brush: absent in Gen 2, present in Gen 3
- Battery runtime: 240 minutes versus 231 minutes
- Self-cleaning tray: Gen 2 lacks it, Gen 3 includes third-generation technology
- Base depth: 456.7 mm versus 457 mm
- Base height: 590.5 mm versus 590 mm
Power and Suction
The most striking technical upgrade between these two generations lies in suction power. The Dreame L10s Ultra Gen 2 delivers 10,000 Pa, which handles everyday dust, crumbs, and light debris without trouble. The Gen 3, however, jumps to 25,000 Pa—a substantial increase that should prove useful for homes with thick rugs, pet hair embedded in carpets, or particularly dusty environments.
Both models use a simple main brush design without anti-tangle features. Neither lifts the main brush during mopping, which is fairly standard at this level. The side brush setup differs: the Gen 2 uses a fixed side brush, whilst the Gen 3 incorporates an extendable side brush. This extension allows the Gen 3 to reach further into corners and along skirting boards, improving edge cleaning performance during vacuuming sessions.
Neither model offers side brush elevation during mopping or anti-tangle technology for the side brush. In practice, this means occasional manual cleaning to remove wound-up hair or fibres.
Mopping
The mopping system remains largely consistent across both generations. Each uses dual rotating mops that extend outwards with a swinging motion, helping to scrub right up to edges and partially under furniture overhangs. Both lift their mops by 10.5 mm when encountering carpets or rugs, preventing wet pads from soaking fabric surfaces.
Water temperature for floor mopping stays cold in both models. The multifunction base washes the mops with cold water and dries them using hot air, which speeds up drying and reduces the risk of unpleasant odours or bacterial growth. Neither robot automatically detaches its mops at the base for vacuum-only runs, nor do they detect dirt levels on mops or floors to trigger additional cleaning passes.
For households with mixed flooring—tiles, laminate, and occasional rugs—the 10.5 mm mop lift should suffice for most low-pile carpets. Thicker rugs may still require manual intervention or designated no-go zones.
Navigation System
Both the Dreame L10s Ultra Gen 2 and Gen 3 rely on a 3D LiDAR turret for mapping and navigation, paired with a front-facing 3D laser sensor for obstacle detection. This combination allows the robots to build accurate floor plans and avoid common household items like shoes, cables, or chair legs.
Pet recognition is included in both models, which can be useful for avoiding pet bowls or toys scattered across the floor. Neither incorporates an AI camera, LED lighting for night vision, or remote camera access. Curtain detection is absent, so care should be taken with long drapes that might interfere with the robot's path.
The CleanGenius AI cleaning feature appears in both generations, adjusting suction and mopping intensity based on room type or detected floor conditions. This automation reduces the need for manual tweaking via the app.
Battery and Autonomy
Battery capacity sits at 5,200 mAh for both models. Interestingly, runtime differs slightly: the Gen 2 manages 240 minutes, whilst the Gen 3 runs for 231 minutes. The nine-minute reduction likely stems from the Gen 3's significantly higher suction power drawing more energy, even though the battery itself hasn't changed.
For most homes, either runtime provides ample coverage. A full charge should comfortably handle flats or houses up to around 200 square metres, depending on floor layout and obstacle density. Neither specification sheet lists charging time, but typical recharge cycles for batteries of this capacity hover around three to four hours.
Smart Features
Both robots can climb obstacles up to 20 mm high, which helps them transition over door thresholds, thick rugs, or slightly uneven flooring without getting stuck. Neither includes a robotic arm for additional object manipulation, nor do they feature a proprietary voice assistant built into the robot itself.
External voice assistant compatibility is present in both models, allowing control via Alexa or Google Home. This enables voice commands for starting, stopping, or sending the robot to specific rooms without opening the app.
Multifunction Base
The base station handles dust collection, mop washing, and mop drying for both models. Dust bags hold 3.2 litres, which typically lasts several weeks before needing replacement. Clean water tanks measure 4.5 litres, whilst dirty water tanks hold 4 litres—generous capacities that reduce refill frequency.
A detergent reservoir is included in both, dispensing cleaning solution during mop washing to improve hygiene and tackle stubborn grime. Neither base offers UV disinfection or automatic mop changing.
The key difference here is the self-cleaning tray. The Gen 2 lacks this feature, meaning the tray where mops are washed can accumulate residue over time and requires manual cleaning. The Gen 3 introduces a third-generation self-cleaning tray that automatically rinses itself, reducing maintenance effort and keeping the base fresher longer.
Both models offer an optional connection kit for plumbing integration, sold separately. This allows the base to draw fresh water and drain dirty water directly, eliminating the need to refill or empty tanks manually. It's a convenience feature rather than a necessity, suited to users who want truly hands-off operation.
Dimensions
The robots themselves are identical in size: 350 mm diameter and 97 mm height. This low profile should allow them to slip under most sofas, beds, and cabinets, reaching dust that often gets neglected.
Base dimensions are nearly identical as well. Width stays at 340 mm for both. The Gen 2 base measures 590.5 mm tall and 456.7 mm deep, whilst the Gen 3 is 590 mm tall and 457 mm deep—differences so marginal they won't affect placement in any meaningful way. Both bases require a fair amount of floor space, so plan for roughly half a metre of depth and width when choosing a location.
Real-World Use
For smaller flats or homes with predominantly hard flooring, the Gen 2 offers solid performance. Its 10,000 Pa suction handles daily dust and light debris, and the multifunction base keeps mopping efficient. However, the lack of a self-cleaning tray means you'll need to scrub the base's washing area every few weeks to prevent grime build-up.
The Gen 3 suits homes with pets, thick carpets, or larger floor areas where higher suction makes a noticeable difference. The 25,000 Pa power digs deeper into carpet fibres and picks up embedded pet hair more effectively. The extendable side brush improves edge cleaning, which matters in rooms with lots of skirting or furniture pushed against walls. The self-cleaning tray reduces hands-on maintenance, making the Gen 3 a better fit for users who want to minimise interaction with the robot and its base.
Both models handle mixed flooring reasonably well thanks to mop lift, though very thick rugs might still need manual vacuuming. The 20 mm obstacle-climbing ability helps with standard door thresholds but won't conquer unusually tall transitions.
Conclusion: Which Should You Choose?
Choose the Dreame L10s Ultra Gen 2 if: you have a smaller home with mostly hard floors, your budget is tighter, and you don't mind occasional manual cleaning of the base's washing tray. The 10,000 Pa suction and 240-minute runtime cover everyday cleaning tasks without issue, and the multifunction base still delivers proper mop washing and drying.
Choose the Dreame L10s Ultra Gen 3 if: you live in a larger home, have pets that shed heavily, or want the strongest suction available for deep carpet cleaning. The extendable side brush improves corner coverage, and the self-cleaning tray cuts down on maintenance. The nine-minute reduction in runtime is a minor trade-off for the substantial power increase and added convenience features.
