Roborock S4 Max Robot Vacuum with LiDAR Navigation

The Roborock S4 Max is a mid-range robot vacuum built on proven LiDAR navigation and solid suction. It delivers 2000Pa of suction for carpet and hard-floor cleaning, uses precise LiDAR mapping to create multi-level floor plans with no-go zones, and runs for up to 150 minutes per charge on a single battery. The vacuum does not mop and lacks a self-empty dock, requiring manual bin emptying after each cleaning cycle. It integrates with Alexa and Google Home via a competent mobile app for scheduling and zone-based cleaning. Best suited for multi-room homes, pet owners, and carpet-heavy floors where strong suction and accurate navigation matter more than premium dock features. Roborock's reputation for reliability in mid-tier robot vacuums is well-earned; the S4 Max represents solid engineering without flagship pricing.
