Pet hair pickup on hard floors was repeatedly described as strong.
Anti-tangle performance is one of the clearest strengths, with several reviewers reporting little or no hair wrapping.
Fine dust pickup on hard floors was a clear strength in everyday testing.
Multiple reviews said it handled larger hard-floor debris well, often in one pass.
The dock’s heated washing system is presented as a meaningful part of the automated cleaning experience.
Compared with competing robot mops, the UV-guided stain targeting and deliberate re-scrubbing feel more distinctive and more useful than most novelty features.
Reviewers repeatedly framed the M16 as unusually feature-rich for its price and as a meaningful step up versus earlier or pricier models.
Larger dry debris such as crumbs, coffee grounds, or snacks were generally handled well.
The low 95 mm profile helps the robot reach low-clearance areas more easily.
Maintenance looks manageable, with rinseable filters and largely self-servicing dock routines, but owners still need to empty tanks and keep an eye on debris capacity.
Ownership is lower-effort than many robots, but it still requires periodic brush, filter, roller, and sensor checks.
Mapping is usually fast and reasonably accurate, but one-floor-only maps, finicky room edits, and occasional routing glitches keep navigation from feeling fully premium.
Mapping was described as quick and accurate, with neat pathing and sensible room segmentation.
The mop lifting and detach-reattach system is widely praised because it avoids dragging wet pads over carpet and makes mixed-floor cleaning far more practical.
The mop-lift system was repeatedly noted as effective for protecting carpets and thicker rugs during mopping.
Mopping is the star of the show, with repeated praise for stain removal, return-to-scrub behavior, and floors that often look close to hand-mopped.
Mopping is one of the strongest parts of the package, especially for everyday grime, sticky spills, and more active scrubbing.
Running noise from the robot itself trends on the loud side, with at least one reviewer calling it rattly even at medium power.
Regular cleaning is usually described as quiet or manageable, but dock emptying and higher-power cleaning are noticeably louder.
Obstacle avoidance is above average and often strong around furniture, cables, shoes, and thresholds, though it is not flawless.
