Roborock S8 Review (2026)
Roborock S8 review: sonic mopping, obstacle avoidance, and suction assessed for real homes, with a clear verdict, limitations, and alternatives.
Roborock S8
Sonic mopping meets smart navigation.
Our verdict
The Roborock S8 is the most complete robot vacuum package in its class. Sonic mopping that actually scrubs, a mop that lifts over carpet, and obstacle avoidance that handles everyday clutter make it the rare robot you can genuinely set and forget. It is a premium-tier product, but it earns the price with features that cheaper robots simply do not have.
What we like
- LiDAR navigation with 3D obstacle avoidance
- VibraRise sonic mopping
- Strong suction with carpet boost
What to watch out for
- Self-empty dock costs extra
- Mopping is maintenance-level, not deep clean
- App has a learning curve
Who it is for
Best for mixed-floor homes that want vacuuming and mopping from one robot, and for anyone tired of rescuing a dumb robot from cords and shoes.
Cleaning performance
The S8 pairs strong suction with a rubber brush roll that resists hair tangles better than bristle designs. On hard floors it picks up fine dust and larger debris in a single pass; on carpet it handles surface dirt well, though like all robots it is a maintenance cleaner rather than a deep-clean replacement.
Mopping
This is where the S8 separates itself. The sonic mop vibrates to scrub rather than just dragging a damp pad, and VibraRise lifts the mop over carpet so rugs stay dry. For homes with mostly hard floors, it meaningfully reduces how often you mop by hand.
Navigation and app
LiDAR mapping builds accurate floor plans with room divisions, no-go zones, and multi-floor support. Reactive 3D obstacle avoidance steers around shoes, cords, and pet toys instead of bulldozing through them. The app is among the most capable in the category, though the depth of options can overwhelm first-time users.

Questions, answered
Does the Roborock S8 mop well?
By robot standards, yes. The vibrating sonic mop scrubs noticeably better than drag-pad designs, and it lifts over carpet automatically. It maintains hard floors well but will not replace occasional manual mopping for stuck-on grime.
Can the S8 avoid pet waste?
Its Reactive 3D obstacle avoidance is designed to recognize and steer around common obstacles including pet waste, though no system is perfect. The Roomba j7+ has the more famous pet-waste avoidance guarantee in the category.
Is the Roborock S8 worth the premium price?
If you want one robot that vacuums and mops well with minimal babysitting, yes. If you only need vacuuming on hard floors, cheaper options like the Shark AI Ultra cover the essentials.
