Introduction
This comparison brings together three robot vacuum cleaners launched between 2024 and 2025, each representing a different approach to automated home cleaning. The Mova E30 Ultra arrived in 2024 as Dreame's secondary brand offering, whilst the Dreame L10s Ultra Gen 3 landed in November 2025 with third-generation improvements. Completing the trio is the Roborock QV 35A from 2025, representing the world's leading robot vacuum manufacturer.
All three feature multifunction bases that handle dust emptying, mop washing with cold water, and hot air drying. They're designed for households seeking minimal maintenance, though their capabilities differ notably in suction power, navigation precision, and overall performance. The Mova targets users wanting solid features at a more accessible price point, whilst the Dreame pushes performance boundaries with significantly higher suction. The Roborock sits between them, offering the brand's renowned reliability.
Suction Power and Cleaning
The suction power comparison reveals the most striking difference between these models. The Dreame L10s Ultra Gen 3 delivers an exceptional 25,000 Pa, which represents a substantial leap over the Roborock QV 35A's 8,000 Pa and the Mova E30 Ultra's 7,000 Pa. In practical terms, this means the Dreame can tackle deeply embedded dirt in carpets and extract debris from tile grout with considerably more force.
All three models use a simplified main brush design, and none offer brush elevation during mopping. The Dreame distinguishes itself with an extendable side brush that reaches further into corners and along skirting boards. The Roborock takes a different approach with an anti-tangle side brush, particularly useful in homes with long hair or pets. The Mova lacks both features.
None of the models elevate their side brushes when mopping, which can be a consideration for those wanting to avoid flicking water around during wet cleaning sessions.
Mopping System
Each robot employs dual rotating mops, but the Dreame L10s Ultra Gen 3 adds functionality the others can't match. Its mop extension system pushes the mop pads outward to reach edges and corners more effectively, complemented by Roboswing technology that creates a subtle swaying motion to clean underneath furniture overhangs and tight spaces.
Mop elevation is present across all three, though with slight variations. The Mova E30 Ultra and Dreame L10s Ultra Gen 3 both lift their mops 10.5 mm when transitioning to carpets or rugs, whilst the Roborock QV 35A manages 10 mm. These differences are minimal in real-world use, but the extra half millimetre might matter on particularly thick carpet edges.
All three clean floors with cold water and wash their mops in the base using cold water as well. Hot air drying is standard across the range, helping prevent odours and bacterial growth on the mop pads between cleaning sessions. None of the models automatically detects dirt on mops or floors, nor do they remove the mops at the base for vacuum-only operation.
Navigation System
LiDAR navigation with rotating turrets features on all three robots, providing accurate room mapping and efficient cleaning paths. The distinction emerges in their obstacle avoidance capabilities.
The Mova E30 Ultra and Dreame L10s Ultra Gen 3 both incorporate 3D laser sensors at the front, allowing more precise detection of low-lying obstacles and furniture legs. They also include pet recognition, useful for avoiding pet bowls, toys, or unexpected accidents. The Roborock QV 35A lacks both the 3D sensor and pet recognition, relying on its standard LiDAR and basic obstacle detection.
None of the three includes a front-facing camera, LED lighting for night vision, or remote camera access. For households wanting visual monitoring capabilities, these aren't the models to consider.
Intelligent cleaning systems are present throughout: CleanGenius on the Mova and Dreame, SmartPlan on the Roborock. These optimize cleaning patterns based on room layout and previous sessions, though none offers AI-powered stain recognition.
Battery and Autonomy
Battery capacity is identical at 5,200 mAh across all three models, but runtime tells a different story. The Dreame L10s Ultra Gen 3 achieves 231 minutes of operation, whilst the Roborock QV 35A manages 180 minutes. The Mova E30 Ultra's autonomy data isn't available for comparison.
For larger homes, the Dreame's extended runtime means fewer interruptions for recharging mid-clean. The Roborock's 180 minutes still covers substantial ground, typically sufficient for properties up to around 150-180 square metres in a single run.
Smart Features
All three robots can climb obstacles up to 20 mm high, handling door thresholds and low-pile rug edges without difficulty. This capability is standard across the range and performs reliably in typical home environments.
External voice assistant compatibility is universal, with Alexa and Google Home integration allowing voice control for starting, stopping, or sending the robot to specific rooms. None incorporates its own voice assistant, relying instead on these established platforms.
Multifunction Base
The base stations handle dust emptying, mop washing with cold water, and hot air drying across all three models. Capacity differences become relevant for maintenance frequency.
The Mova E30 Ultra and Dreame L10s Ultra Gen 3 share 3.2-litre dust bags, 4.5-litre clean water tanks, and 4-litre dirty water tanks. The Roborock QV 35A has slightly smaller capacities: a 2.7-litre dust bag, 4-litre clean water tank, and 3.5-litre dirty water tank. In practice, this means the Roborock requires more frequent bag changes and water refills in larger homes.
The Dreame L10s Ultra Gen 3 stands apart with third-generation automatic tray cleaning, which maintains the washing tray hygienically between sessions. It also includes a detergent dispenser, adding cleaning solution during mop washing for better results. Neither the Mova nor Roborock offers these features.
An optional plumbing connection kit is available for the Dreame, though it's purchased separately and not a built-in feature. This allows automatic water refilling and drainage for those wanting to eliminate manual tank maintenance entirely. The Mova and Roborock don't offer this option.
Dimensions
The robots themselves are remarkably similar in size. The Mova E30 Ultra and Dreame L10s Ultra Gen 3 both measure 350 mm in diameter and 97 mm in height. The Roborock QV 35A is fractionally larger at 353 mm diameter but slightly lower at 96.5 mm. These minimal differences won't affect which furniture they can clean beneath.
Base dimensions vary more noticeably. Whilst width remains consistent at 340 mm across all three, the heights differ. The Mova E30 Ultra's base reaches 590.5 mm, the Dreame 590 mm, and the Roborock is notably more compact at 521 mm. Depth also varies: the Roborock extends 487 mm, compared to around 457 mm for the Mova and Dreame. For those with limited space or specific cupboard installations, the Roborock's lower profile might prove advantageous.
Real-World Performance
The Dreame L10s Ultra Gen 3 suits larger properties where its 25,000 Pa suction, 231-minute runtime, and 3.2-litre dust capacity work together to cover extensive areas thoroughly. The extendable brush and mop with Roboswing movement deliver superior edge cleaning, particularly valuable in homes with complex layouts or abundant skirting detail. The third-generation tray cleaning and detergent dispenser reduce maintenance involvement.
Homes with pets benefit from the Mova E30 Ultra or Dreame L10s Ultra Gen 3 due to their pet recognition capabilities, though the Dreame's significantly higher suction makes it more effective at lifting embedded pet hair from carpets and upholstery edges.
The Roborock QV 35A offers reliable performance for medium-sized homes, with its anti-tangle side brush proving useful in households with long hair. The more compact base fits into tighter spaces, and Roborock's reputation for app stability and long-term reliability appeals to those prioritizing consistent operation over cutting-edge features.
All three handle hard floors, parquet, and low to medium-pile carpets effectively, with their 10-10.5 mm mop elevation protecting most rug types during mopping cycles.
Conclusion: Which Should You Choose?
Choose the Mova E30 Ultra if you want a capable robot with multifunction base features at a more accessible price point, particularly if you value 3D sensors and pet recognition but don't need the highest suction power or longest runtime.
