One reviewer noted hair could get trapped in crevices and need manual attention.

Hair-removal channel feedback was mixed to negative due to hair wrapping or needing to pull lingering hair from the bin.

Under-furniture pickup was praised in one review for the thin wand and flexible head joint.

Under-furniture pickup was positive, with reviewers saying it handled under-furniture cleaning and tight spaces well.

The automatic shutoff behavior was described positively as motor protection when airflow is blocked.

Dirty-water sensing was a clear weakness in TechRadar's review because the display only showed clean-water level, not dirty-water buildup.

Dried-on stain performance ranged from excellent one- or two-pass results to needing many extra passes or struggling with overnight sticky stains.

Floor drying time was praised in two reviews, with quick drying and floors not left saturated after mopping.

Fresh liquid pickup was useful for small spills and standalone liquids, but multiple reviews warned against large wet spills or wet-solid mixtures.

One review highlighted the product's versatility as the factor that sets it apart from other wet-dry mops.

Mopping performance was useful for light cleaning, small spills, and general maintenance, but reviews agreed it is not a full true wet-dry or deep-clean replacement.

Sanitizing feedback was negative because the Submarine cannot steam-sterilize floors.

The lack of an auto self-cleaning cycle was a repeated weakness, making mop-head cleanup more manual than competing wet-dry vacuums.

The self-propelled mopping feel was praised as lightweight and easy to propel along.

Liquid delivery feedback was mixed: some liked the controlled water output, while others disliked the single wet mode and lack of water-flow adjustment.

The product does not provide steam cleaning, and one review treated that as a limitation versus hot, sterilizing mop methods.

Streaking and residue were recurring mop-head concerns, especially after pauses, large spills, dirty rollers, or uneven initial water flow.

Stuck resistance was weaker on rugs when suction was too high, requiring users to lower power.
