Robot vacuums with a mopping function have come a long way in recent years—yet two problems persist with many models: The round, often rather bulky design frequently gets stuck in front of low furniture, and when mopping, the same supply of water is dragged across the floor until it itself becomes a source of dirt. For pet owners, a third annoyance often comes into play: pet hair that gets tangled around the brush roll and must be removed by hand after every cleaning cycle.
Lefant aims to address precisely these three issues with the M210 Pro Omni . The manufacturer—which, according to its own statements, has been producing everything in-house for over 20 years and can therefore avoid distributor markups—positions the model as a compact all-rounder: an ultra-slim 280-millimeter body for greater access under furniture, a roller mop with real-time fresh-water cleaning instead of mopping with dirty water, and a 100 percent tangle-free brushless suction port for households with pets. We’ll summarize what’s behind the technology, how the Lefant M210 Pro Omni stacks up against well-known competing models, and who should take a closer look at this robot vacuum.

Lefant M210 Pro Omni at a Glance
- An ultra-slim 280-mm body glides under beds, sofas, and kitchen cabinets and, according to the manufacturer, achieves up to 92% cleaning coverage
- Real-time fresh-water roller mop with a 4-step cycle (spray water → mop → scrape off dirt → drain dirty water)
- 20-cm mop roller with 240 rpm and constant contact pressure of 15 N to tackle dried-on stains like coffee, sauce, or milk
- 20,000 Pa suction power combined with a 100% tangle-free, brushless suction port—no replacement brushes required
- Two side brushes instead of the single brush common on many competing models, for better edge cleaning
- 800-ml dust bin without disposable bags; according to the manufacturer, it can hold up to two weeks’ worth of dirt
- All-in-one self-cleaning station with a 2.4-liter fresh water tank and a 1.5-liter dirty water tank: refilling, draining, rinsing the mopping roller, and drying all occur automatically

- Dual-band 2.4 GHz/5 GHz Wi-Fi, including compatibility with the Apple Watch
Sleek design: Smaller size, greater range
Many traditional robot vacuums with round bodies have a diameter of about 350 millimeters, which means they regularly get stuck in front of low furniture, bed edges, or kitchen baseboards. The Lefant M210 Pro Omni counters this with an ultra-slim 280-millimeter body that, according to the manufacturer, glides effortlessly under beds, sofas, kitchen cabinets, and other low furniture gaps.
In practice, this translates to a significantly larger cleaned area: Lefant specifies a cleaning coverage of up to 92 percent—a figure that, due to their design, larger competing models struggle to match, especially in apartments with plenty of low storage space or rooms with many nooks and crannies. According to the manufacturer, the compact design is intended to make a noticeable difference in the actual cleaning coverage, especially for smaller apartments or rooms with many furniture legs.
Real-Time Fresh-Water Mopping with On-the-Go Roller Cleaning
A key selling point of the M210 Pro Omni is its real-time fresh-water cleaning system. Unlike mopping functions that repeatedly drag the same batch of water across the floor, the M210 Pro Omni operates according to a complete 4-step cycle: spraying water, wiping and scrubbing, scraping off dirt, and then immediately removing the dirty water. This ensures that the floor is consistently wiped with fresh water rather than water that has already been contaminated.
This is made possible by a 20-centimeter-long mop roller that rotates at 240 revolutions per minute while applying a constant contact pressure of 15 newtons to the floor. According to the manufacturer, this is sufficient to reliably remove stubborn, dried-on stains such as coffee, soy sauce, fruit juice, milk, or ketchup—stains that simple mop pads or rotating mop heads often fail to remove.
20,000 Pa Suction Power & Tangle-Free Suction Port
In terms of pure suction power, the M210 Pro Omni delivers 20,000 Pa to pick up dust, crumbs, and pet hair from both carpets and hard floors. For households with pets, however, another detail is likely even more important: the 100 percent tangle-free, brushless suction inlet. Instead of a traditional brush roll—which hair tends to wrap around and must be manually cleared regularly—the M210 Pro Omni completely eliminates the rotating brush at the intake.
According to Lefant, this has two direct advantages: First, it eliminates the tedious task of cutting out tangled hair after each cleaning session; second, the suction inlet remains clear at all times, ensuring that suction power stays consistent over the long term rather than declining due to clogged brushes. This eliminates the need for additional replacement brushes as wear parts.
Two side brushes and a large 800-ml dust bin
While many competing models use only a single side brush, Lefant has equipped the M210 Pro Omni with two side brushes. This is designed to ensure that dirt and crumbs along edges, in corners, and at the legs of furniture are more reliably directed toward the suction port instead of being left behind.
The collected dirt is stored in an 800-milliliter dust bin inside the robot itself, which, according to the manufacturer, can hold up to two weeks’ worth of dirt without needing to be emptied. Since disposable dust bags are completely eliminated, households also avoid the usual ongoing costs for consumables.
All-in-One Self-Cleaning Station
At the heart of this maintenance-free design is the M210 Pro Omni’s all-in-one base station. It features a 2.4-liter fresh water tank and a separate 1.5-liter dirty water tank. When the robot returns to the station, the entire maintenance process runs automatically: fresh water is refilled, wastewater is drained, the mop roller is rinsed, and then air-dried.
For users, this means that no manual maintenance is required throughout the entire mopping process—no replacing mop pads, no manual refilling, and no emptying a dirty mop tank after each pass. According to Lefant, this—especially in combination with the real-time fresh water system—is designed to ensure that users practically no longer have to worry about the entire mopping process themselves.
Obstacle Detection and Patented Freemove Sensing Technology
To navigate around obstacles, the M210 Pro Omni relies on the PSD 2.0 obstacle detection system: 9 sensor sets provide a 190-degree detection angle with no blind spots.
This is complemented by the patented Freemove full-body sensor system, which, according to Lefant, is a globally patented all-around collision detection system. Multi-sensor fusion algorithms are designed to provide protection against getting stuck or jammed across the entire robot body—not just at a traditional, movable front bumper, as found on many other models. The seamless chassis design, which lacks moving mechanical parts, is also intended to prevent dirt and lint from becoming lodged in joints and crevices, which, according to the manufacturer, contributes to longer-lasting, more stable performance throughout the robot’s lifespan.
Seamless Smart Control
When it comes to connectivity, Lefant relies on dual-band 2.4 GHz/5 GHz Wi-Fi to avoid unstable connections and failed pairing attempts, which occasionally occur with devices that operate solely on the 2.4 GHz band. In addition, the M210 Pro Omni is compatible with the Apple Watch, allowing you to conveniently control the robot remotely while on the go. The control system also supports Google Assistant and Alexa for voice control, as well as voice prompts for status updates.
