Dreame L40s Ultra CE Robot Vacuum and Mop vs iRobot Roomba Max 715

The Roomba Max 715 is the safer pick for carpeted homes with pets and for anyone who wants low-maintenance, obstacle-aware cleaning. The Dreame L40s Ultra is the stronger choice for hard floors and for people who want real mopping, not just a mop attachment. The Dreame wins on raw suction, mopping hardware and self-washing mops; the Roomba wins on navigation, obstacle avoidance, app polish and a lighter, simpler design. Owners of the Dreame praise the TriCut brush for long hair and pet hair but report getting stuck on furniture and a learning curve in the app.

• Choose the Dreame L40s Ultra if you have mostly hard floors, long hair or shedding pets, and you want two spinning mops that wash and dry themselves.
• Choose the Roomba Max 715 if you have carpets, clutter or pet accidents to avoid, and you want set-and-forget emptying with a mature app.
