2026 verdict
Is the Dreame D30 Ultra worth the step up from the Dreame D20 Air Plus?
For most buyers, yes: this robot vacuum trades a modest price increase for 25,000Pa suction, up to 230 minutes of runtime, a 4.5L water tank and a dock that washes and dries the mop pad automatically, none of which the Dreame D20 Air Plus offers. The Dreame D20 Air Plus still holds the price advantage and carries a slightly bigger 4L dock bag, so it remains the cheaper way into Dreame's self-emptying lineup. Both share the same 3-year warranty and identical smart-home support. Buyers who want proper mop washing and drying and stronger suction should pay the difference for the Dreame D30 Ultra; those who mainly vacuum and want to spend less should stick with the Dreame D20 Air Plus.
