2026 verdict
Dreame D30 Ultra tops Dreame D20 Pro Plus on suction, mopping automation and water tank capacity in this robot vacuum comparison, delivering 25,000Pa of suction and a dock that washes and dries its mop pad, features the Dreame D20 Pro Plus does not have. The Dreame D20 Pro Plus punches back with a lower price, more runtime at up to 285 minutes, a bigger 500ml onboard bin and an unusually large 5L dust bag rated for 150 days. Both carry the same 3-year warranty and the same smart-home support. Buyers who mop regularly and want the dock to handle pad hygiene should pick the Dreame D30 Ultra; those who prioritize runtime and dust bag capacity at a lower price should pick the Dreame D20 Pro Plus.
