<h2>Two Approaches to Navigation</h2><p>Modern robot vacuums use LiDAR or camera-based vision. Some premium models like the <a href="/robot-vacuums/roborock-s8-maxv-ultra">Roborock S8 MaxV Ultra</a> combine both.</p><h2>How LiDAR Works</h2><p>LiDAR uses a spinning laser sensor to create precise 3D maps. It measures distances by calculating how long laser pulses take to bounce back, creating centimeter-accurate room maps.</p><h2>How Camera Navigation Works</h2><p>Camera systems use onboard cameras with AI processing to visually recognize rooms and objects. iRobot PrecisionVision on the <a href="/robot-vacuums/irobot-roomba-combo-j9-plus">Roomba Combo j9+</a> uses this approach.</p><h2>LiDAR Advantages</h2><p>More precise mapping, works in complete darkness, faster map creation, and consistent performance. LiDAR robots clean more efficiently with fewer missed spots.</p><h2>Camera Advantages</h2><p>Better at identifying specific objects, can distinguish between obstacle types, and enables pet waste detection. Lower profile design without turret.</p><h2>Our Recommendation</h2><p>For most buyers, LiDAR navigation is better due to precision and consistency. Camera obstacle avoidance adds safety for pet homes. The best models combine both.</p>
