Introduction
The Mova E30 Ultra and Mova E40 Ultra represent two generations of robot vacuum cleaners from Mova's premium range. The E30 Ultra launched in 2024, whilst the E40 Ultra arrived in 2025 with several meaningful upgrades. Both models feature multifunction bases that handle automatic dust emptying, mop washing with cold water, and drying—though the newer model introduces hot air drying. These are comprehensive cleaning systems designed for users who want minimal manual intervention, particularly in homes with mixed flooring types.
At first glance, the two models share many core specifications. They're identically sized, use the same battery capacity, and employ similar navigation systems. The differences, however, lie in suction power, mop extension capabilities, and a few refinements in the cleaning system that could matter depending on your home environment and cleaning expectations.
Power and Suction
Here's where the comparison becomes particularly interesting. The Mova E40 Ultra offers 19,000 Pa of suction power—nearly triple the 7,000 Pa found in the E30 Ultra. In practical terms, this means the newer model can extract embedded dirt from carpets more effectively and handle larger debris without multiple passes. For homes with pets or high-traffic areas, this difference becomes noticeable quickly.
Both models use a standard main brush without anti-tangle features, and neither offers brush elevation during mopping. The side brush setup is where things diverge slightly: the E40 Ultra incorporates anti-tangle technology on its side brush, which helps reduce maintenance time if you deal with hair regularly. Neither model extends or elevates the side brush, so corner cleaning relies on navigation precision rather than mechanical reach.
The 5,200 mAh battery capacity is identical across both robots. The E40 Ultra specifies 210 minutes of runtime, which should comfortably cover larger homes in a single session. The E30 Ultra doesn't list autonomy figures, though the battery capacity suggests similar performance under comparable conditions.
Mopping
Both robots use dual rotating mops and elevate them by 10.5 mm when encountering carpets or rugs. This clearance works well for low-pile carpets but may not fully protect thicker rugs during mixed cleaning sessions. The mopping water remains cold in both cases—no heated water reaches the floor itself.
The E40 Ultra introduces mop extension with movement capability, allowing the mops to reach closer to skirting boards and into corners. The E30 Ultra lacks this feature, so edge mopping coverage will be less thorough. For homes with extensive hard flooring and detailed edges, this becomes a meaningful advantage.
Neither model automatically detects dirt on mops or floors to trigger re-mopping, and neither can automatically detach mops at the base for vacuum-only sessions. You'll need to manage mopping tasks manually through the app or remove mops physically if you want pure vacuuming across carpeted areas.
Navigation System
Navigation hardware is essentially identical. Both models use a 3D LiDAR turret combined with a frontal 3D laser sensor for obstacle detection. Pet recognition is available on both, which helps the robots navigate around animals without getting stuck or causing disturbance. Neither includes a frontal AI camera, LED lighting for night vision, or remote camera access—features sometimes found in competing premium models.
The CleanGenius AI cleaning system appears on both robots, managing room recognition, cleaning schedules, and route optimisation. In daily use, navigation performance should feel very similar between the two models, with differences in cleaning results stemming more from suction power and mopping refinements than mapping capability.
Battery and Autonomy
With matching 5,200 mAh batteries, both robots share the same energy foundation. The E40 Ultra specifies 210 minutes of runtime, which translates to substantial coverage before returning to the base. This autonomy suits larger homes or thorough cleaning sessions that include multiple rooms with varied floor types.
Charging times aren't specified for either model, though typical recharge cycles for batteries of this capacity range between three and four hours. The multifunction base handles charging automatically, so the robot returns when needed and resumes cleaning if the job isn't finished.
Smart Features
Both models can climb obstacles up to 20 mm high—sufficient for most door thresholds and minor floor transitions. Neither includes a robotic arm for object manipulation, nor do they feature proprietary voice assistants. Integration with external voice platforms like Alexa and Google Home is supported on both, allowing basic voice control for starting, stopping, or returning to base.
The CleanGenius AI system manages intelligent cleaning patterns, but without dirt detection sensors on the floor or mops, the robots won't automatically identify heavily soiled areas for extra attention. Cleaning thoroughness depends more on scheduled frequency and suction strength than adaptive intelligence.
Multifunction Cleaning Base
Both bases handle automatic dust emptying into a 3.2-litre bag, mop washing with cold water, and mop drying. The clean water tank holds 4.5 litres, whilst the dirty water tank manages 4 litres. This capacity supports multiple cleaning sessions before manual refilling or emptying becomes necessary.
The E40 Ultra upgrades mop drying to hot air, which accelerates drying time and helps prevent odours or bacterial growth on the mop pads. The E30 Ultra uses cold air drying, which works but takes longer and may not be as effective at odour prevention over time.
An optional detergent tank can be purchased separately for the E40 Ultra, dispensing cleaning solution during mop washing at the base. The E30 Ultra doesn't offer this option. Neither base includes automatic tray self-cleaning, UV disinfection, or plumbing connection—features that remain in higher-tier models from other brands.
Base dimensions are identical: 340 mm wide, 590.5 mm tall, and 456.7 mm deep. You'll need similar floor space for either model, so placement considerations don't change between the two.
Dimensions
The robots themselves are identical in size: 350 mm diameter and 97 mm tall. This height allows them to slip under most furniture, though very low-clearance beds or sofas may still pose challenges. The compact profile suits typical home layouts without requiring special accommodation.
With matching dimensions, neither model has an advantage in tight spaces or under-furniture access. Your choice won't be influenced by size constraints.
Real-World Use Experience
For smaller homes or flats with primarily hard floors, the E30 Ultra handles daily maintenance comfortably. The 7,000 Pa suction manages surface debris and light dirt without issue, though deeper carpet cleaning or embedded pet hair may require more frequent sessions.
The E40 Ultra suits larger homes, particularly those with pets or mixed flooring. The 19,000 Pa suction tackles carpets more aggressively, and the 210-minute autonomy ensures complete coverage in spacious layouts. Mop extension improves edge cleaning along skirting boards, which becomes more noticeable in open-plan spaces with extensive hard flooring.
Hot air mop drying on the E40 Ultra reduces maintenance attention—mops dry faster and stay fresher between uses. For households running daily cleaning cycles, this small refinement adds up over time. The optional detergent tank further reduces manual intervention, though it's an additional purchase.
Both models require similar upkeep: emptying the dirty water tank, refilling clean water, and replacing the dust bag when full. The E40 Ultra's anti-tangle side brush may reduce hair-clearing frequency if you have long-haired occupants or pets.
Conclusion: Which to Choose?
Choose the Mova E30 Ultra if: you have a smaller home with mostly hard floors, don't need maximum suction power, and want to save money on a capable robot vacuum with multifunction base features. It handles routine cleaning well and includes the core conveniences of automatic dust emptying and mop washing.
Choose the Mova E40 Ultra if: you need stronger suction for carpets or pet hair, have a larger home requiring extended runtime, value better edge mopping with mop extension, or prefer hot air mop drying for faster, fresher results. The optional detergent tank and anti-tangle side brush add convenience for users wanting minimal hands-on maintenance. This model represents a more future-proofed investment if you expect cleaning demands to grow.
