Source: dreametech.com (verified 2026-07-07) · corroborated by amazon.com. Re-fetched and verified 2026-07-09. The dreametech.com X40 Ultra product page confirms verbatim: 12,000Pa Vormax suction ("Maximum Suction (Pa) 12,000Pa" in its X40-vs-X30 spec table, plus "12,000Pa Vormax™ Suction"), auto-emptying into a 3.2L dust bag for up to 75 days (self_empty), MopExtend RoboSwing mopping with 158°F hot-water mop self-cleaning and hot-air drying (mopping), obstacle avoidance listed as "AI RGB + 3D Structured Light" that "identifies and avoids over 120 types of objects, from shoes to cables" with a built-in LED (obstacle_avoidance), and control "in the Dreamehome App" (app). It lists the battery only as 6,400mAh with no runtime in minutes, and shows a regular price of $1,199.99 (on sale $539.99). The Amazon retailer page (B0D534DYFR) corroborates the exact "dreame X40 Ultra" model (Model Number / ASIN confirmed) at 12,000Pa suction, 75-day self-emptying, Vacuum-and-Mop with 10.5mm mop lift, and supplies the navigation technology in its "Navigation Technical" field for the X40 Ultra column ("Lidar+ 3D structured+AI+LED"), so mapping is recorded as the normalized LiDAR Navigation category (LiDAR is explicitly part of the X40 nav stack; the manufacturer page never names the nav tech). release=2024: the Amazon "From the brand" description states Dreame "launched the Dreame X40 series in February 2024" (the manufacturer page does not state a launch date). battery_min is null: the manufacturer gives only 6,400mAh, and Amazon is internally contradictory (its comparison table shows 198min for the X40 Ultra column while the Product Information table lists 260 minutes), so no single runtime could be trusted (null beats a guess). Exact model confirmed as the X40 Ultra, distinct from the X30 Ultra column shown alongside it in both comparison tables.
