The Lefant M310 Ultra has a relatively compact footprint, measuring 280 mm in width and thickness with a height of 79 mm, and weighs 3020 g. It includes both a HEPA filter and an allergy filter, making it suitable for households that need finer particulate capture. Operating noise is rated at 60 dB, which sits at a moderate level for a robot vacuum. The unit is compatible with both Google Assistant and Amazon Alexa, allowing for voice-based control. It comes with a one-year warranty.
The Lefant M310 Ultra supports mapping and route mapping, enabling it to navigate in an organized pattern rather than moving randomly, and it also allows users to define no-go zones to restrict access to specific areas of the home. An obstacle sensor, anti-fall sensor, and anti-stuck functionality work together to help the robot navigate safely across different surfaces, and carpet detection is included as well. Cleaning can be scheduled in advance, and the unit returns to its dock automatically when done or when the battery runs low. It can be controlled via a physical remote control or through a smartphone app, and voice prompts provide audio feedback during operation. On the connectivity side, it uses Wi-Fi 4 (802.11n), though the Wi-Fi toggle is listed as not supported. It does not offer self-emptying, virtual barriers, water level adjustment, or any mopping-related functions such as mop cleaning, mop raising, or mop drying.
The Lefant M310 Ultra features a 0.5-litre dustbin that operates without bags, so there are no ongoing consumable costs tied to the collection system. It is equipped with twin side brushes to help sweep debris toward the suction path along edges and corners. The unit does not include a display or automatic height adjustment, keeping the design relatively straightforward.
The Lefant M310 Ultra delivers 6000 Pa of suction power and is rated to clean all floor types, with five cleaning modes available to adjust how it tackles different areas or levels of dirt. It also includes basic mopping capability alongside its vacuuming function. The unit does not have a dirt sensor, an electrostatic filtration system, or UV light sanitization.
The Lefant M310 Ultra is powered by a 2600 mAh battery that supports up to 170 minutes of runtime per charge, with a full recharge taking approximately four hours. It includes an auto-off function that cuts power automatically when appropriate, though it does not have an overheating indicator. The battery is not removable.
