Introduction
The Dreame X40 Ultra and the Xiaomi Robot Vacuum 5 Pro represent two high-end propositions in the robot vacuum market with multifunction base stations. The Dreame model arrived in 2024, whilst the Xiaomi launched in 2025. Both are designed for users seeking complete autonomy in home cleaning, with vacuuming, mopping and automatic mop maintenance capabilities.
We're talking about devices designed for medium or large homes that require effective mopping in addition to vacuuming. The differences between them are concentrated in aspects such as suction power, brush configuration and some details in the base station that can make a difference to the daily user experience.
Power and Suction
The most notable difference in this section is suction power. The Xiaomi Robot Vacuum 5 Pro offers 20,000 Pa, a figure considerably higher than the 12,000 Pa of the Dreame X40 Ultra. In practice, this translates to greater capacity for removing ingrained dirt from carpets or heavy debris on hard floors.
The brushing system also presents interesting variations. The Xiaomi features a TriCut 3.0 brush, which combines bristles with blades designed to cut hair and prevent tangles. The Dreame is equipped with a simple brush, less specialised in this aspect. For homes with pets, this can make a difference in maintenance.
Both models lift the main brush during mopping, which prevents it from getting wet and improves mopping efficiency. However, only the Dreame X40 Ultra also lifts the side brush during these sessions, a detail that can reduce splashing and improve results at edges.
Both are equipped with an extendable and anti-tangle side brush, which facilitates corner cleaning and reduces maintenance in this area.
Mopping
Both robots use two rotating mops for mopping, a system that offers good results on hard floors. The Dreame X40 Ultra integrates the Roboswing system, which performs a lateral movement to introduce the mop under furniture and overhangs. The Xiaomi also features mop extension, although without specifying this type of movement.
Mop lifting presents differences: the Xiaomi Robot Vacuum 5 Pro raises them up to 15 mm, compared to the 10.5 mm of the Dreame. This can be relevant when passing over short-pile carpets, although for thicker carpets both models will require care.
An exclusive function of the Dreame X40 Ultra is automatic mop removal at the base station. When you only want to vacuum, the robot removes the mops without manual intervention, something the Xiaomi doesn't offer. For homes with many carpets or areas that only require vacuuming, this represents an advantage in convenience.
Both robots detect dirt on both the mops and the floor, adjusting the scrubbing or washing as necessary. The base station of both washes the mops with hot water and dries them with hot air, which helps keep them hygienic and odour-free.
Navigation System
The Dreame X40 Ultra features a 3D LiDAR turret, whilst the Xiaomi uses a retractable LiDAR. Both systems allow precise mapping and efficient route planning. The Xiaomi's retractable LiDAR can offer advantages when passing under very low furniture, although its height of 88 mm is already quite reduced.
In terms of artificial intelligence, the Dreame integrates a dual camera and the AI Sage 11.0 Quantum system, capable of recognising up to 120 objects. The Xiaomi also features an AI camera and recognises up to 200 objects, a higher figure that can translate to better obstacle avoidance in complex environments.
The Dreame X40 Ultra specifically identifies pets and curtains, two elements that may require adjustments in cleaning. The Xiaomi does not specify these recognition functions. Both allow remote access to the camera and feature LEDs for night vision.
Autonomy and Battery
The Dreame X40 Ultra stands out with a 6,400 mAh battery that offers up to 194 minutes of autonomy. The Xiaomi Robot Vacuum 5 Pro features a 5,200 mAh battery with 140 minutes of autonomy. The difference is considerable: almost an hour more of continuous work for the Dreame model.
For large homes, this extra autonomy can mean completing the cleaning in a single session without the need for intermediate recharging. The Xiaomi, with its greater suction power, consumes more energy, which partly explains this difference despite being a more recent model.
Smart Functions
Both robots overcome obstacles, although with slight differences: the Dreame X40 Ultra can surmount up to 22 mm in height, whilst the Xiaomi reaches 20 mm. In practice, both values are sufficient for passing over thin carpets and small level changes between rooms.
Both devices are compatible with external voice assistants such as Alexa or Google Home, facilitating voice control without needing to open the mobile application.
Multifunction Cleaning Base Station
The base stations of both models include auto-emptying of the dust bin, mop washing with hot water and drying with hot air. The Dreame X40 Ultra incorporates second-generation tray self-cleaning, whilst the Xiaomi also features this function without specifying generation.
An important difference: only the Dreame X40 Ultra includes a detergent tank in the base station. This allows dispensing cleaning product during mop washing, improving mopping results. The Xiaomi does not offer this option.
The dust bag capacity is greater in the Dreame: 3.2 litres compared to 2.5 litres for the Xiaomi. The water tanks are also slightly larger in the Dreame model: 4.5 litres of clean water and 4 litres of dirty water, compared to 4 and 3.8 litres respectively in the Xiaomi.
The Dreame X40 Ultra allows the purchase of an optional plumbing connection kit, although it must be purchased separately. The Xiaomi does not offer this possibility.
Dimensions
Both robots have the same diameter: 350 mm. Height is where the main difference appears: the Xiaomi Robot Vacuum 5 Pro measures 88 mm, whilst the Dreame X40 Ultra reaches 97 mm. These 9 mm can determine whether or not the robot passes under certain low furniture, sofas or beds with little clearance.
The base stations present similar dimensions, with slight variations. The Dreame measures 340 mm wide, 590.5 mm high and 456.7 mm deep. The Xiaomi is somewhat wider (360 mm) and deeper (470 mm), but slightly lower (572 mm). It's advisable to measure the available space before deciding where to position the base station.
Real-World User Experience
For large homes, the Dreame X40 Ultra offers clear advantages thanks to its greater autonomy and base station capabilities. The 194 minutes of continuous work allow covering large surfaces without interruptions, and the detergent tank adds a bonus in mopping. Automatic mop removal is especially practical if you alternate between areas with carpets and hard floors.
The Xiaomi Robot Vacuum 5 Pro excels in homes that prioritise suction power. The 20,000 Pa is ideal for thick carpets or pets that shed a lot of hair, especially combined with the TriCut 3.0 brush. Its lower height facilitates access under low furniture.
In homes with pets, the Dreame has the advantage of specific animal recognition and the detergent tank for keeping the mops cleaner. However, the Xiaomi compensates with its anti-tangle brush and greater suction power for picking up hair.
For users seeking maximum autonomy in maintenance, the Dreame offers greater capacity in the dust bag and water tanks, reducing the frequency of emptying and refilling.
Conclusion: Which to Choose?
Choose the Dreame X40 Ultra if: You have a large home that requires long cleaning sessions, you value automatic mop removal for alternating between vacuuming and mopping, you want to use detergent in mop washing, or you need greater capacity in the base station tanks to reduce maintenance. Also if you have pets and value their specific recognition.
Choose the Xiaomi Robot Vacuum 5 Pro if: You prioritise maximum suction power for thick carpets or difficult dirt, you need a lower robot to pass under furniture with little clearance, or you're looking for the highest number of recognised objects for obstacle avoidance. Its TriCut 3.0 brush is also an advantage if you have pets with long hair.
Both are high-end robots with complete multifunction base stations. The choice depends on whether you value more the autonomy and versatility of the Dreame, or the raw power and reduced height of the Xiaomi.
