Verdict

The Roborock Q8 is a mixed bag: it offers great coverage, strong battery life, and outstanding hair-tangle resistance, but struggles with obstacle avoidance, dock noise, and mopping. It’s best suited for open spaces and pet hair, not for quiet homes with cluttered floors or people who want serious mopping.

Pros

  • Hair‑Wrap / Tangle Resistance 1 review 5.0
    Hair-tangle resistance is excellent: short and long hair tests leave almost no strands wrapped on the brush, and the Q8 ranks at the top for resisting hair build-up.
  • Ongoing ownership costs (bags, filters, batteries) 1 review 4.8
    Long-term consumable costs are low thanks to a generous dust bag and reasonably priced filters, giving the Q8 one of the lowest projected five-year ownership costs after the Q5.
  • Battery & Charging 1 review 4.0
    Battery life and coverage are strong, with the Q8 tying the Q5 for cleaning roughly twice the surface area of most rivals per charge, making it well-suited to larger homes.
  • Price & Value 1 review 4.0
    Considering its low five-year cost and strong cleaning and hair performance, the Q8 offers good value for buyers who prioritize vacuuming over quietness, advanced avoidance, or high-end mopping.
  • Overall opinion 1 review 3.8
    Overall, the Q8 is regarded as a capable budget-friendly option with great coverage, runtime, and hair handling but clear compromises in obstacle avoidance, dock noise, and mopping ability.
  • Hard Floor — Fine Dust Pickup 1 review 3.5
    On hard floors, the Q8 provides decent but not standout performance, usually picking up most flour and cereal but leaving a bit more debris than the top-ranked models in mixed-mess tests.

Cons

  • Noise level 1 review 3.2
    Noise levels are moderate, with average readings around 60 dB that place the Q8 in the middle of the pack—quieter than the loudest models but far from the quietest Q Revo designs.
  • Dock noise 1 review 2.0
    The dock is notably loud during auto-empty cycles, standing out as one of the noisiest stations tested and best placed away from frequently used living areas.
  • Mopping performance 1 review 2.0
    Mopping is largely ineffective, as the pad barely lightens dried stains during one-pass tests and leaves it grouped with the poorest performers for floor washing.
  • Obstacle Avoidance (Robot) 1 review 1.5
    Obstacle avoidance is weak, as the Q8 repeatedly runs into remotes, boxes, and taller items during tests, earning one of the lowest scores for avoiding everyday floor clutter.
