Lefant M330 Pro Robot Vacuum with Mop vs roborock Saros 10 Robot Vacuum Cleaner 22

Navigation and Mapping Technology

The roborock Saros 10 offers a more advanced navigation system than the Lefant M330 Pro, featuring a combination of LiDAR, RGB camera, and structured light sensors, while the Lefant relies on dToF laser navigation. The Lefant M330 Pro uses dToF laser technology with a 15-metre scanning range to create accurate home maps, navigating intelligently around obstacles even in low light. It also employs wide-angle PSD sensors with a 190° detection range to minimise collisions. In comparison, the roborock Saros 10 utilises front triple structured light, an RGB camera, and VertiBeam lateral structured light, allowing for real-time obstacle detection and precise edge cleaning. Its retractable LDS sensor adapts height automatically, maintaining a 100° viewing angle even in challenging spaces. This reactive AI 3.0 system ensures the Saros 10 responds within milliseconds, making it better suited for complex home layouts.

Suction Power and Cleaning Performance

The roborock Saros 10 significantly outperforms the Lefant M330 Pro in suction power, delivering up to 22,000Pa compared to the Lefant’s 5,000Pa. This difference means the Saros 10 can lift more embedded dust, pet hair, and debris, making it especially effective for homes with pets or heavy dirt. The Lefant’s 5,000Pa suction is still strong for its price range and can handle everyday cleaning well, but it cannot match the Saros 10’s intensity. Additionally, the Saros 10 features a tangle-free main brush with TUV SGS dual certification, which enhances its cleaning efficiency by avoiding hair wrap and maintaining consistent suction. The Lefant is also pet-friendly with anti-tangle suction ports and anti-hair wrap technology, but its lower suction power limits its overall performance.

Mopping Capabilities

The roborock Saros 10 has a more sophisticated mopping system with its VibraRise 4.0 self-detaching mop, which can automatically assemble and disassemble for vacuuming and mopping transitions. It also uses Hot Water Sonic Vibration at up to 4,000 vibrations per minute for superior stain removal over a larger area. The Lefant M330 Pro features simultaneous vacuuming and mopping with a 200mL water tank and washable mop pad, providing a straightforward one-pass clean for sticky dirt. However, it lacks the advanced vibration or self-detaching technology found in the Saros 10. Furthermore, the Saros 10’s auto-lifting brush and mop system adapts to different surfaces, preventing moisture damage on carpets, whereas the Lefant simply avoids carpets during mopping. Overall, the Saros 10 offers a more versatile and thorough mopping experience.

Design and Build

The Lefant M330 Pro is an ultra-slim robot at just 9.5cm tall, allowing it to clean under low-clearance furniture like sofas and beds effectively. It also has wide-angle PSD sensors that detect obstacles within a 190° range to reduce collisions. The roborock Saros 10 is even slimmer at 3.14 inches (approximately 8cm), with a retractable LDS sensor and top-mounted ToF sensor that smartly adjusts height to maintain optimal cleaning angles in tight spaces and low light. Both vacuums are designed to access hard-to-reach areas, but the Saros 10’s additional sensor adaptability gives it an edge in complex environments. Additionally, the Lefant’s transparent 450mL dustbin makes it easy to check capacity, while the Saros 10’s dustbin size isn’t specified but is supported by a sophisticated RockDock Ultra station for maintenance.

Battery Life and Runtime

The Lefant M330 Pro offers up to 150 minutes of continuous runtime on a single charge, which is ample for moderate-sized homes and daily cleaning. The roborock Saros 10’s precise runtime details are not provided, but its advanced docking station supports fast charging and off-peak charging, suggesting efficient energy management. The Lefant’s runtime is a clear metric here, providing nearly two and a half hours of cleaning, while the Saros 10 likely matches or exceeds this with its flagship features and enhanced docking capabilities. For users prioritising longer uninterrupted cleaning, the Lefant’s stated runtime is reassuring, but the Saros 10’s infrastructure hints at strong endurance and quick turnaround.

Smart Features and App Control

Both robots offer smart app control and voice assistant compatibility, but the Lefant M330 Pro supports dual-band Wi-Fi (2.4G/5G) and can be controlled via the Lefant App with features like scheduling, no-go zones, and suction power adjustment. It also integrates with Alexa and Google Assistant for voice commands. The roborock Saros 10 boasts a more advanced perception system with AI-driven obstacle recognition and an intelligent docking station that includes self-cleaning, auto detergent dispensing, and self-refilling capabilities. These advanced features imply a higher level of automation and convenience, reducing user intervention. Although specific app functionalities for the Saros 10 are not listed, its integration with a smart RockDock Ultra suggests a more premium smart home experience.

Maintenance and Convenience

The Lefant M330 Pro is designed with easy maintenance in mind, featuring an anti-tangle suction port and a large transparent dustbin that allows users to monitor when it needs emptying. It also has washable mop pads, which help reduce replacement costs. The roborock Saros 10 takes maintenance convenience further with its New Generation RockDock Ultra docking station. This station offers hot water mop washing at 80°C, dynamic temperature settings for different stains, heated air drying at 60°C, and self-cleaning with warm water. Additionally, it has an intelligent dirt detection system and automatic detergent dispensing. These features dramatically reduce the frequency and effort of manual cleaning, making the Saros 10 ideal for those seeking a near-hands-free cleaning solution.

Which should you buy?

Choosing between the Lefant M330 Pro and the roborock Saros 10 depends primarily on your budget and desired level of cleaning sophistication. The Lefant M330 Pro delivers excellent value at £189.99, offering solid suction power, simultaneous vacuuming and mopping, and reliable navigation suitable for everyday use in typical homes. Its long 150-minute runtime and pet-friendly design are notable strengths for the price-conscious buyer.

However, if budget allows, the roborock Saros 10 at £899.99 provides a vastly more advanced cleaning experience with 22,000Pa suction, superior AI navigation, a highly effective VibraRise mopping system, and a near-automated maintenance dock. Its smart features and precision obstacle avoidance make it well suited for larger or complex living spaces, and for users who want minimal manual intervention.

In summary, go for the Lefant M330 Pro if you want a capable, affordable robot vacuum with good navigation and mopping in one device. Opt for the roborock Saros 10 if you prioritise cutting-edge cleaning technology, powerful suction, and a fully automated maintenance system, and are willing to invest significantly more for these premium features.
