Dreame D30 Ultra CE vs Dreame L40 Ultra Gen 2

Full Robot Vacuums comparison in 2026

Updated September 2026
Data from Amazon and official Dreame site.
2026 verdict
Same 25000Pa, and Gen 2 still takes the page: the Dreame L40 Ultra Gen 2 wins this robot vacuum comparison on price, a 231-minute battery, and a broader upcoming-platform path against the Dreame D30 Ultra CE.
The CE's only clear hardware edge is a 300ml onboard bin versus 250ml. Both list 3-year warranties, 3.2L bags, and LiDAR docks that wash and dry mops. Matter on the L40 Ultra Gen 2 is an upcoming OTA update, while the CE stays on Alexa, Google Home, and Home Assistant. Choose the Dreame L40 Ultra Gen 2 for the cheaper 25000Pa Dreame with extendable side-brush reach; choose the Dreame D30 Ultra CE if the larger onboard bin is the detail you care about.
