We may earn a commission from retailer links. Commissions do not affect ratings, rankings, or verdicts. Observed prices are snapshots, not live offers.

The evidence is thin here — fewer than three model-level owner comments. The rating is calculated, but a single comment carries a lot of weight; the # Recommendations component stays low until more owners weigh in.

Who it suits

Not enough feature or theme evidence to say.

Who should skip it

  • You want one machine to vacuum and mop — this is vacuum only.
  • You want weeks between bin trips — there is no self-empty dock.
  • Your floors are cluttered with cables, socks, or pet toys — obstacle avoidance is not claimed.
  • You want a long track record — the owner evidence here is still thin.

What the specs mean in practice

Suction is rated at 2,000 Pa, higher than 2% of tracked models. Pa is a manufacturer figure, not measured airflow — owners judge cleaning by pet hair and carpet results, so treat it as a floor rather than a verdict.

A 150-minute runtime is below the roughly 180-minute norm; larger homes may see it return to recharge mid-clean.

The dock is listed as "charge-only".
