Key Technical Factors to Consider Before Buying
Suction Power and Surface Adaptability
Suction power in a Roborock Saros Z70 Robot Vacuum is measured in Pascals (Pa), and the range across our tested units spans from 3,000Pa entry-level models to 25,000Pa flagship configurations. Raw Pa numbers alone are not sufficient to judge real-world performance; the design of the main brush, the dustbin inlet geometry, and the motor efficiency all influence how effectively a unit extracts embedded debris from carpet fibers. The Dreame D30 Ultra CE, for example, delivers 25,000Pa and pairs it with 20 integrated spray nozzles on its washing system, making it one of the most capable units in this category for homes with both thick rugs and hard floors. To compare alternative configurations, check our hands-on review of why robot vacuum keeps getting lost lidar fix.
Carpet detection and automatic suction boost are equally important. Models like the Lefant M2 Plus (6,000Pa) and the Lefant M3 (15,000Pa) both feature automatic suction escalation when transitioning onto carpet surfaces, ensuring deeper fiber cleaning without requiring manual mode adjustments. When the mop pad is attached, both units also automatically avoid carpet zones to prevent moisture damage, a critical feature for mixed-surface homes.
Navigation Technology and Mapping Accuracy
LiDAR (Light Detection and Ranging) is the current standard for precision navigation in a Roborock Saros Z70 Robot Vacuum. Units equipped with LiDAR perform 360-degree real-time scanning to build accurate floor plans, enabling systematic row-by-row cleaning patterns rather than random-path coverage. The Roborock Saros Z70 takes this further with its StarSight Autonomous System 2.0, which combines LiDAR with VertiBeam Lateral Obstacle Avoidance to detect and navigate around 108 recognized obstacle types, including cables, furniture legs, and small objects. The iRobot Roomba 105X uses ClearView LiDAR for efficient row-based cleaning, while the Shark IQ RV2302AE employs 360-degree LiDAR Vision with Matrix Clean grid patterns for systematic coverage.
