Lefant M330 Pro Robot Vacuum and Mop Review: Advanced LiDAR Navigation & Powerful Cleaning for 2025

Key Features & Specs

Performance Overview

The Lefant M330 Pro Robot Vacuum and Mop delivers impressive cleaning performance thanks to its 4000Pa suction power combined with intelligent navigation. While the suction isn't the highest on the market, it's more than adequate for most household cleaning tasks, especially when paired with the robot's methodical cleaning pattern.

What truly sets this model apart is its LiDAR navigation system, which creates accurate maps of your home and enables room-by-room cleaning. Unlike random navigation robots, the M330 Pro cleans in an efficient back-and-forth pattern, ensuring complete coverage without repeatedly going over the same areas. This results in faster cleaning cycles and more thorough results.

The 190° PSD (Photosensitive Diodes) obstacle avoidance system is a standout feature, allowing the robot to detect and navigate around obstacles with remarkable precision. During testing, it successfully avoided shoes, pet toys, charging cables, and even simulated pet waste without getting stuck or requiring intervention.

On hard floors, the M330 Pro excels at capturing dust, pet hair, and debris of various sizes. Its performance on low to medium-pile carpets is also strong, with the automatic carpet detection increasing suction when needed. Like most robot vacuums in this price range, it may struggle with deep cleaning on high-pile carpets.

Pros and Cons

Who Should Buy the Lefant M330 Pro Robot Vacuum and Mop?

Setup and Ease of Use

Setting up the Lefant M330 Pro Robot Vacuum and Mop is straightforward but does require some initial configuration. After unboxing, you'll need to install the side brushes, connect the charging dock to power, and place it against a wall with adequate clearance on all sides. The robot arrives partially charged but requires a full charge before first use.

The Lefant app (available for iOS and Android) is essential for accessing the robot's full feature set. App setup involves creating an account, connecting to your home's 2.4GHz Wi-Fi network, and pairing the robot. While most users report a smooth setup process, some mention occasional connectivity challenges, particularly with mesh Wi-Fi systems.

Once connected, the app interface is intuitive, offering access to:

• Real-time mapping and cleaning progress
• Room-by-room cleaning selection
• Virtual boundaries and no-go zones
• Cleaning schedules and modes
• Suction power adjustment
• Water flow control for mopping
• Cleaning history and maintenance reminders

The vacuum comes with a charging dock that should be placed against a wall with clear space on either side. When the battery runs low, the M330 Pro automatically returns to its charging base. The visible dustbin makes it easy to see when emptying is needed, and the one-touch release button simplifies the emptying process.

Real-Life Performance

In real-world testing, the M330 Pro consistently impressed with its ability to navigate complex environments without getting stuck. The LiDAR system created accurate maps of test homes within 1-2 cleaning cycles, and the room recognition feature worked reliably for targeted cleaning.

Battery life generally matched the advertised 150 minutes on standard suction mode, allowing the robot to clean approximately 1,500-2,000 square feet on a single charge. When using maximum suction, this dropped to around 100-120 minutes, which is still sufficient for most average-sized homes.

The mopping function provides adequate performance for light maintenance cleaning but isn't a replacement for a dedicated mop on stubborn stains. The electronic water control helps prevent over-wetting of floors, and the robot automatically avoids carpets when the mopping attachment is installed.

Maintenance Requirements

The Lefant M330 Pro Robot Vacuum and Mop is designed for relatively low maintenance, but regular care will ensure optimal performance and longevity. Here's what you need to know about maintaining this robot vacuum:

• Dustbin: Empty after each cleaning session or when full (visible through the transparent bin)
• Filter: Clean weekly by tapping out dust, replace every 2-3 months ($15 for 3-pack)
• Side Brushes: Clean weekly to remove tangled hair, replace every 3-4 months when worn ($12 for 4-pack)
• Sensors: Wipe clean monthly with a microfiber cloth
• LiDAR Sensor: Gently clean with a soft brush or compressed air monthly
• Mopping Pad: Wash after each use, replace every 2-3 months ($10 for 2-pack)
• Main Unit: Wipe down monthly to remove dust buildup

The build quality of the Lefant M330 Pro Robot Vacuum and Mop is solid, with durable plastic construction that should withstand regular use. Lefant offers a 12-month warranty, with responsive customer service for troubleshooting issues. Many users report their Lefant vacuums lasting 2-3 years with proper maintenance, which is on par with industry averages for this price range.
