Introduction
Choosing between the Mova E30 Ultra and the two Roborock models we're presenting requires a good understanding of what type of cleaning you need. The Mova E30 Ultra is a robot launched in 2024 with a complete multifunction base, whilst the Roborock QV 35A from 2025 also incorporates this automatic mop washing technology. The third model, the Roborock Q7 L5+ or BF+ Plus from 2025, represents a more basic proposition focused exclusively on vacuuming with auto-empty.
The fundamental difference lies in the mopping system. Two of these units feature stations that automatically wash and dry the mops, guaranteeing practically zero maintenance for weeks. The third dispenses with these functions and uses a traditional static mop, making it an option designed for those who prioritise vacuuming or have tighter budgets.
Power and Suction
Suction power marks a first clear difference. The two Roborock models reach 8,000 Pa, whilst the Mova E30 Ultra stays at 7,000 Pa. In practice, this variation may be particularly noticeable on carpets or when there's accumulated pet hair, although both levels are sufficient for most homes.
All three units mount simple-type main brushes, without advanced anti-tangle technologies. None raises the main brush during mopping, something common at this price range. Where a specific advantage does appear is in the Roborock QV 35A's side brush, which incorporates an anti-tangle system. This reduces manual maintenance and prevents tangles of hair forming around the side arm, a frequent problem in homes with pets.
None of the three models features an extendable or liftable side brush. For homes with long-haired animals, the QV 35A's anti-tangle side brush represents a real advantage over the Mova E30 Ultra and the Q7 L5+ or BF+ Plus.
Mopping
Here we find the most important difference in this robot vacuum comparison. The Mova E30 Ultra and the Roborock QV 35A integrate two rotating mops that are automatically washed at the base with hot water and dried with hot air. This system guarantees that the mops return clean to the floor on each pass, notably improving mopping quality compared to traditional systems.
The Roborock Q7 L5+ or BF+ Plus mounts a static mop that doesn't wash or dry automatically. You'll need to remove it, wash it by hand and reattach it each time it mops. It doesn't lift the mop either, which means that if you activate mixed vacuum-mop mode, the mop will drag across carpets or areas you'd prefer to keep dry.
The Mova E30 Ultra lifts the mops up to 10.5 mm, slightly more than the Roborock QV 35A's 10 mm. Both can pass over thin carpets without wetting them when mopping. None of the three models extends the mops to better reach edges nor automatically removes the mops at the base to perform vacuuming only.
For those seeking minimal maintenance and effective mopping, choosing between the Mova E30 Ultra and the Roborock QV 35A makes more sense than opting for the Q7 L5+ or BF+ Plus, unless mopping isn't a priority.
Navigation System
All three robots use LiDAR turret with laser mapping, which ensures precise navigation and creation of detailed maps of the home. However, the Mova E30 Ultra adds a front 3D laser sensor that improves detection of low and small obstacles. This model also incorporates pet recognition, useful if you have dogs or cats and want to avoid areas where they usually rest or eat.
The Roborock QV 35A features obstacle avoidance, but doesn't specify a 3D laser sensor nor specific pet recognition. The Q7 L5+ or BF+ Plus directly dispenses with advanced avoidance systems, limiting itself to basic LiDAR. This means it may collide with small objects like cables, toys or slippers, something the other two models avoid with greater precision.
None integrates a camera with remote access, night vision LED nor curtain detection. The Mova E30 Ultra incorporates AI intelligent cleaning (CleanGenius), whilst the Roborock QV 35A uses SmartPlan. The Q7 L5+ or BF+ Plus lacks these intelligent functions.
Autonomy and Battery
The Mova E30 Ultra and the Roborock QV 35A mount 5,200 mAh batteries. The QV 35A specifies 180 minutes of autonomy, sufficient to clean homes of up to 200 m² in a single charge. The Mova E30 Ultra doesn't detail the exact minutes, but with the same battery capacity should offer similar performance.
The Roborock Q7 L5+ or BF+ Plus drops to 3,200 mAh, a considerable difference that limits its autonomy. In large houses it may need intermediate recharges, something the other two models avoid without problems. This is worth bearing in mind if you live in a large space or with several floors.
Smart Functions
All three robots overcome obstacles up to 20 mm in height, allowing them to pass over door joints, thick cables or small level changes without getting stuck. None incorporates a robotic arm nor its own voice assistant, although all three are compatible with Alexa and Google Home for external voice control.
Multifunction Cleaning Base
The Mova E30 Ultra and the Roborock QV 35A feature multifunction bases that auto-empty dust, wash the mops with hot water and dry them with hot air. The main difference lies in the tank capacities. The Mova E30 Ultra offers 3.2 litres of dust bag, 4.5 litres of clean water and 4 litres of dirty water. The Roborock QV 35A slightly reduces these figures: 2.7 litres of dust, 4 litres of clean water and 3.5 litres of dirty water.
In practice, the Mova E30 Ultra allows you to space out emptying the dust bag and refilling clean water more, especially useful in large homes or with pets that generate lots of hair and dirt. The Roborock QV 35A still offers weeks of autonomy, but will require slightly more frequent maintenance.
The Roborock Q7 L5+ or BF+ Plus only auto-empties dust into a 2.7-litre bag. It doesn't wash or dry mops, and lacks water tanks in the base. Its station is much more compact: 212 mm wide, 259 mm high and 178 mm deep, compared to over 450 mm depth of the multifunction bases.
None of the three integrates self-cleaning wash tray, UV disinfection, detergent tank, automatic mop changing nor plumbing connection.
Dimensions
The Roborock Q7 L5+ or BF+ Plus is the most compact, with 325 mm diameter and 99 mm height. The Mova E30 Ultra reaches 350 mm diameter and 97 mm height, being the lowest of the three. The Roborock QV 35A measures 353 mm diameter and 96.5 mm height, practically identical to the Mova in height.
These millimetric differences barely affect the ability to pass under furniture. All three can slip under standard sofas or beds without problems. Where things do change is with the bases. The Mova E30 Ultra and the Roborock QV 35A require ample spaces due to their multifunction bases, whilst the Q7 L5+ or BF+ Plus station occupies less than half.
Real-World User Experience
For large homes over 120 m², the Mova E30 Ultra or the Roborock QV 35A are more suitable thanks to their 5,200 mAh batteries and multifunction bases with generous tanks. The Q7 L5+ or BF+ Plus may fall short on autonomy and requires manual intervention for mopping.
If you live with pets, the Roborock QV 35A's anti-tangle side brush reduces maintenance. The Mova E30 Ultra compensates with its specific pet recognition and front 3D laser sensor, which better avoids feeders, toys or occasional droppings. The Q7 L5+ or BF+ Plus lacks these advantages.
In homes where mopping is fundamental, the choice narrows to Mova E30 Ultra or Roborock QV 35A. Both automatically wash and dry mops, guaranteeing consistent results without touching anything for weeks. The Q7 L5+ or BF+ Plus only makes sense if you prioritise vacuuming exclusively or have a more limited budget.
Conclusion: Which to Choose?
Choose the Mova E30 Ultra if you're looking for the largest tank capacity in the base (3.2 litres of dust, 4.5 litres of clean water), value pet recognition and the front 3D laser sensor, and prefer to space out maintenance to the maximum. Ideal for large homes with animals and users who want to completely forget about cleaning for weeks.
Choose the Roborock QV 35A if you prioritise 8,000 Pa of suction power, the anti-tangle side brush and the reliability of Roborock as a world-leading brand. It offers a complete multifunction base with slightly smaller tanks than the Mova, but sufficient for most homes. A good option for those seeking balance between advanced features and brand confidence.
Choose the Roborock Q7 L5+ or BF+ Plus if mopping isn't a priority, you have limited space for the base, or you're looking for a more economical solution focused on vacuuming with auto-empty. Suitable for small flats without pets, mainly hard floors that don't require frequent mopping, or as a complement to other manual floor cleaning.
