2026 verdict
Need 25000Pa and a 3-year warranty in one dock?
The Dreame L40 Ultra Gen 2 is the robot vacuum that wins every counted row, on price, reviews, warranty, 231-minute battery life, suction, and a 3.2L dock dustbin. The Roborock Qrevo Edge S5A still mops, washes and dries pads, and self-empties at 18500Pa and 180 minutes with Home Assistant already YES (the Dreame lists HA as upcoming OTA). Both LiDAR-map. Choose the Dreame L40 Ultra Gen 2 for power, tanks, and warranty; choose the Roborock Qrevo Edge S5A if you want Home Assistant today and the quieter 52dB Qrevo.
