The onboard dustbin drew repeated criticism for poor usable capacity and filling quickly, even though auto-empty helped.

The bag system worked well with official bags, but a reviewer warned that poor-fitting third-party bags could disrupt auto-emptying.

Dust containment was a weakness in one owner review because hair and dust could spill when the bin was partly full.

Dust containment was mixed: one review found the internal bin nearly empty after auto-emptying, while another saw dust and litter left behind.

Corner cleaning was praised because the extending side brush and mop helped reach true corners.

Corner performance was mixed: one reviewer praised side-brush edge and corner cleaning, while another found crumbs left near the wall.

Reliability was mostly good, but one owner reported a map glitch that temporarily ruined the map.

Reliability evidence was mixed: one reviewer found it efficient and reliable, while another felt it fell short of expectations.

Bag and mop-related replacements were described as simple, including easy bag replacement.

Tool changes were mixed: brushroll hair cleanup was easy, but changing the non-detachable mop cloth was more awkward.

Hair-wrap resistance was mixed: some reviewers praised anti-tangle design, while tests found long hair still tangled badly.

Hair-tangle performance was mostly positive thanks to rubber dual rollers, though some tests still found tangles or middling rankings.

Value-for-money was split: Vacuum Wars called it exceptional, while one reviewer thought a cheaper Pro model cleaned similarly.

Value-for-money was split; high automation impressed some reviewers, but comparative and price-focused reviews questioned the premium.

Crevice pickup was a weak spot on default power, although maximum power improved results.
