The headline numbers here are the 450ml visible dustbin and the 150-minute runtime. A visible bin means the owner can see when it needs emptying without pulling out a phone or guessing from a light, and 450ml is a reasonable capacity for a compact robot that cleans a few rooms per run.
The 190° PSD obstacle avoidance is the feature that separates this model from the cheapest robots on the shelf. PSD sensors scan ahead of the unit and slow it before it bumps into furniture legs, cables or pet bowls, which cuts down on the nudging and dragging that plagues budget bots.
Multi-floor mapping is the other differentiator. The M330 Pro can store more than one floor plan, so a buyer who moves the robot between an upstairs and a downstairs can let it reorient instead of rebuilding a map every time. That is unusual at this price tier.

How the M330 Pro Is Built
The 450ml visible dustbin is the most practical design choice on the M330 Pro. Because the bin is clear, the owner sees the fill level at a glance, which matters in a home with shedding pets — a bin that fills quietly mid-run stops picking up hair without any warning. The trade-off is that a 450ml bin on a compact robot fills faster than the larger bins on premium models, so a full-house clean on a heavy-shedding day may need a mid-run empty.
The 190° PSD obstacle avoidance shapes how the robot moves through a room. PSD sensing is a light-based proximity system, and at a 190° spread it covers a wide arc in front of the unit. In practice, that means fewer hard collisions with chair legs and baseboards than a bump-and-go robot delivers, and less chance of dragging a charging cable across the floor.
Multi-floor mapping and customized cleaning work together for buyers with more than one level or more than one routine. The robot can hold separate maps and clean a chosen area on command rather than running the whole floor every time. The catch is that mapping accuracy on a budget sensor suite is not the same as the lidar-driven maps on premium robots — buyers should expect a good working map, not a pixel-perfect one.

Capacity, Runtime and Coverage
The 150-minute runtime is the number that decides how much floor the M330 Pro can cover in one charge. At that figure, the robot can handle a typical apartment or a single floor of a house on one run, with enough margin to finish a second pass in the main living area. Larger homes will need the robot to return to its dock and resume, which most modern robots handle automatically.
The 450ml bin pairs with that runtime in a predictable way: the longer the run, the more the bin fills. For a pet-free home with hard floors, one bin load covers several cleans. For a home with a heavy-shedding dog and wall-to-wall carpet, the bin may need emptying partway through a long run.
Carpet and pet hair are named as the target surfaces, which fits the brush-and-suction layout of a robot in this class. The M330 Pro is built to pull hair off low-pile carpet and hard floors, not to deep-clean shag. Buyers with thick carpet should set expectations for surface cleaning rather than a deep extraction.

Power, Connectivity and Customized Cleaning
The 2.4G/5G WiFi support is a genuine convenience at this price. Many budget robots are limited to the 2.4GHz band, which forces buyers to split their network or run a separate SSID. Dual-band support means the M330 Pro joins the home network most people already have, and the app can schedule cleans and adjust settings without a workaround.
Customized cleaning is the app-side feature that lets the owner set per-room or per-zone behavior — a stronger pass in the kitchen, a quieter run in the bedroom. This is where the multi-floor mapping pays off, because separate maps mean separate routines for each level.
The power tier here is entry-level, and that shapes what the robot does well. It is built for maintenance cleaning — daily passes that keep floors free of dust, crumbs and pet hair — rather than for rescuing a carpet that has gone weeks without attention. Buyers who want a robot to replace a weekly deep vacuum should look higher up the range.

Maintenance and Everyday Ownership
Routine maintenance on the M330 Pro is the standard robot-vacuum routine: empty the visible bin, clear hair from the brush, and wipe the sensors so the PSD obstacle avoidance keeps its accuracy. The clear bin makes the first task easy to judge, and the sensor wipe is the one owners of any PSD robot tend to forget.
The mop function adds a small amount of upkeep. Mopping robots in this class typically use a reservoir and a cloth pad, and the pad needs rinsing after use and replacing when it wears. Buyers should treat the mop as a light-duty freshening tool for hard floors, not a substitute for a proper mop on sticky spills.
Battery and dock care follow the usual pattern for a 150-minute robot: keep the dock clear, let the robot return on its own, and avoid storing it off the dock for long stretches. None of this is demanding, but it is the difference between a robot that lasts and one that gets relegated to a closet.

Strengths and Weaknesses
Trade-off: The M330 Pro trades premium-grade mapping precision and deep-cleaning power for a low price, so buyers who need a flawless map or a true carpet deep-clean will outgrow it.
The strengths sit where a budget buyer needs them: dual-band WiFi, a visible bin, wide-angle obstacle avoidance and multi-floor mapping are all features that make daily ownership easier, and they are rare together at this price. The 150-minute runtime covers a typical home without babysitting.
The weaknesses are the ones that come with the tier. Mapping is good but not lidar-precise, the bin is small enough to need emptying on heavy-shedding days, and the mop is a light freshening tool rather than a scrubber. None of these are dealbreakers for the right buyer — they are the reasons the price is what it is.

Who Should Buy the Lefant M330 Pro
The M330 Pro suits apartment dwellers, renters and pet owners who want scheduled maintenance cleaning without a premium outlay. It also fits multi-level homes where the robot can be carried between floors and allowed to reorient using stored maps.
It is not for buyers with wall-to-wall deep-pile carpet, households that expect a robot to replace a full weekly deep vacuum, or anyone who needs a mop that scrubs. Those buyers should budget for a higher tier. For everyone else, the M330 Pro covers the basics well.
