Roborock S8 Max Ultra

Name: Roborock S8 Max Ultra
Brand: Roborock
SKU: 3666

Manufacturer: Roborock

The Roborock S8 Max Ultra is a full-featured robot vacuum cleaner designed to handle both vacuuming and mopping in a largely automated way. It supports self-emptying, returning to its docking station to offload debris without manual intervention, and includes auto docking, scheduled cleaning, and smartphone remote control through a companion app. Mapping and route-mapping capabilities allow it to navigate spaces methodically, while no-go zones and virtual barriers give users control over where the robot operates.

On the performance side, the S8 Max Ultra delivers 10000 Pa of suction power across four cleaning modes and is rated for all floor types. Its mopping system includes water level adjustment, mop raising for carpet transitions, and automatic mop drying at the dock. The robot runs on a 5200 mAh battery offering up to 180 minutes of runtime per charge, with a full recharge taking approximately 4 hours. It carries a HEPA filter with washable filter support, operates at 67 dB, and weighs 4900 g with a height of 96.5 mm. Alexa and Google Assistant compatibility is included, and the unit carries a one-year warranty.

Pros

Delivers 10000 Pa of suction across four cleaning modes, covering a wide range of floor types in a single unit
Self-emptying function reduces how often the dustbin needs manual attention
Mopping system includes automatic mop raising on carpets and mop drying at the dock, reducing hands-on maintenance
Supports mapping, route mapping, no-go zones, and virtual barriers for precise control over cleaning areas
180-minute runtime per charge allows extended cleaning sessions without interruption
Compatible with both Google Assistant and Alexa for voice-based control

Cons

Charge time of 4 hours is relatively long relative to the battery runtime offered
Dustbin capacity of 0.35 l is modest, which may require more frequent emptying in households without self-emptying use
Does not include a dirt sensor, so cleaning intensity cannot adjust automatically based on floor conditions
No voice prompts, which limits on-device feedback during operation
Battery is not removable, making in-field replacement or long-term servicing more difficult
French Repairability Index score of 6 out of 10 suggests moderate repairability, which may affect long-term serviceability

Who is this for?

This robot vacuum is well-suited to users who want a largely hands-off cleaning routine, thanks to its self-emptying function, auto docking, and scheduled cleaning support. Households with mixed flooring will benefit from its ability to clean all floor types, automatically raise the mop on carpets, and dry the mop pad at the dock without manual intervention. The extensive navigation toolkit — including mapping, no-go zones, virtual barriers, and obstacle sensing — makes it a practical fit for larger or more complex living spaces where precise control over cleaning zones matters. Users comfortable managing the robot through a smartphone app and voice assistants will find the Wi-Fi connectivity with Google Assistant and Alexa support a natural fit for their setup.

Who is this NOT for?

Users looking for a compact docking solution may find the setup impractical, as the docking station occupies over 80000 cm³, requiring a dedicated and reasonably sized floor area. Those who prefer a robot that provides on-device audio feedback during operation will be disappointed, as the unit lacks voice prompts. The non-removable battery and a French Repairability Index score of 6 make this a less suitable choice for users who prioritize long-term self-serviceability or easy component replacement. Additionally, the absence of a dirt sensor means the robot cannot automatically intensify cleaning in heavily soiled areas, which may be a drawback in environments that frequently deal with concentrated messes.
