Dreame D30 Ultra CE vs iRobot Roomba 105 Combo

Full Robot Vacuums comparison in 2026

Updated August 2026
Data from Amazon and official Dreame and iRobot sites.
2026 verdict
Both of these robots mop, but only one does the maintenance for you. The iRobot Roomba 105 Combo mops with water only, no detergent-free washing or drying of its pads, and has no self-emptying dock, so the bin still needs manual attention. The Dreame D30 Ultra CE's dock washes and dries its mop pads and empties the bin automatically, and it runs longer per charge, reaches Home Assistant on top of Google Home and Alexa, and carries a three-year warranty against one year on the iRobot Roomba 105 Combo. The iRobot Roomba 105 Combo's advantage is a lower entry price for buyers who want basic combined vacuuming and mopping without paying for automation. If hands-off maintenance matters, the Dreame D30 Ultra CE is the stronger buy.
