Data from the official Dreame and iRobot sites.
2026 verdict
Same self-washing dock idea, different battery math: the iRobot Roomba 505X matches the Dreame X50 Ultra on mopping automation and broad smart-home support, but it runs for a shorter stretch on a single charge, 180 minutes against 220.
The Dreame X50 Ultra comes out ahead overall on runtime and warranty length, while the iRobot Roomba 505X answers with a lower price and dual-band Wi-Fi. Both use LiDAR mapping and wash and dry their own mop pads automatically. Buyers who want the longest runtime and the longest warranty should choose the Dreame X50 Ultra; those prioritizing price with the same mopping automation can still do well with the iRobot Roomba 505X.
