Dreame D30 Ultra vs Eufy E28

The Dreame D30 Ultra backs a three-year warranty (against one year for the Eufy E28) with stronger suction, a bigger water tank and a longer charge. The Eufy E28 pulls back with a higher owner rating and a broader smart home reach, supporting Apple HomeKit, Samsung SmartThings and Matter alongside Bluetooth, none of which the Dreame D30 Ultra offers. That portable deep cleaner is a genuine bonus for upholstery, stairs and car interiors that the Dreame D30 Ultra simply does not have. Buyers who want that extra tool and wider ecosystem support should pick the Eufy E28; those who want more raw cleaning power, a bigger tank and a much longer warranty at a lower price should choose the Dreame D30 Ultra.
