2026 verdict
A full mopping combo against a compaction-only vacuum: the Dreame D30 Ultra CE mops as well as vacuums, with a dock that washes and dries its own pads and empties itself, while the iRobot Roomba 205 skips mopping entirely and relies on an internal DustCompactor instead of a bagged dock. The Dreame D30 Ultra CE also runs longer per charge and reaches further into smart home platforms with Home Assistant support, and it ships with a much longer warranty. The iRobot Roomba 205's only real edge is its lower price, plus a smaller charging base that some buyers prefer over a bulky auto-empty tower. For anyone who wants vacuuming and mopping handled by one automated machine, the Dreame D30 Ultra CE is the stronger buy; those who specifically want to avoid a bulky dock and don't need mopping may still like the compact iRobot Roomba 205.
