Pa (Pascals)

The unit Roborock uses to rate suction strength — higher means more pull. Our lineup ranges from 5,500 Pa to 25,000 Pa. More Pa matters most for thick carpet and pet hair; on hard floors, the gap is less noticeable. A higher price doesn't always mean higher Pa — check the number itself, not the tier name.

mAh (Battery Capacity)

Battery size in milliamp-hours. We show this instead of a "square feet per charge" number because Roborock doesn't publish sq ft coverage for most models — mAh is the closest real, manufacturer-confirmed figure for how much home a unit can cover before it needs to dock and recharge.

Dual Anti-Tangle / Dual Zero-Tangle

Brush designs built to stop long hair and pet fur from wrapping around the roller — less time spent cutting hair out of the brush bar by hand.

LiDAR (PreciSense®, 360°)

A laser-based mapping system that builds a precise floor plan of your home, so the robot cleans in efficient rows instead of bumping around randomly.

StarSight™ Autonomous System

Roborock's current-generation Saros navigation platform — combines mapping and object recognition to handle complex, cluttered rooms with less manual "no-go zone" setup.

Reactive Tech / Reactive AI (2.0 / 3.0)

Obstacle-avoidance generations, in order of sophistication: Reactive Tech is the base version; Reactive AI 2.0 and ReactiveAI® 3.0 add smarter, more precise real-time object recognition so the robot steers around cords, shoes, and pet bowls instead of pushing through them.

OmniGrip™ Mechanical Arm

Exclusive to the Saros Z70 in our lineup — a 5-axis robotic arm that can physically pick up and move small objects (like a sock or a toy) out of its path, rather than just steering around them.

VibraRise® (2.0 / 4.0)

A mop pad that vibrates against the floor to scrub, rather than just dragging a wet cloth — and lifts up automatically when it senses carpet, so it doesn't soak your rugs.

FlexiArm™

An extending mop arm that reaches out to clean along edges and into corners a fixed mop pad would miss.

SpiraFlow / DuoRoller

Self-cleaning roller-style mop designs — the roller rinses itself with clean water during the cleaning cycle instead of dragging around one increasingly dirty pad.

AdaptiLift™ Chassis

Lets the robot automatically raise its mop and adjust its height when it transitions from hard floor onto carpet, so carpet doesn't get wet.

Auto-Empty

The dock empties the robot's dustbin into a larger bag automatically after each run — you empty the dock's bag every few weeks instead of the robot's small bin every day or two.

RockDock® Ultra

Roborock's most capable dock tier — beyond auto-empty, it can wash and hot-air dry the mop pads and, on "Refill & Drainage" configurations, plumb directly into your water line so you never manually refill or empty the mop's water tank.

Multifunctional Dock

A step below RockDock® Ultra — typically handles auto-empty plus mop washing, without the plumbed refill/drainage option.
