Our Verdict
DREAME L40s Ultra CE Wins
Boasts significantly higher 13,000Pa suction and a more advanced base that hot-air dries mops and holds 100 days of dust. Choose Roomba 104 for its bag-based self-emptying dock if that's preferred.

Frequently Asked Questions
Common questions about this comparison
Which robot vacuum is better for pet hair?
The DREAME L40s Ultra CE is superior for pet hair with its 13,000Pa suction and TriCut Brush, specifically designed to cut hair and prevent tangles. The Roomba 104 also vacuums pet hair effectively, but lacks this specialized brush technology for long hairs.
What's the main difference in suction power between the two?
The DREAME L40s Ultra CE offers a powerful 13,000Pa suction, explicitly listed. The iRobot Roomba 104 states "70X power-lifting suction" but does not provide a specific Pa rating, making direct comparison difficult based on raw numbers.
Which robot offers a more advanced self-emptying base?
The DREAME L40s Ultra CE has a more advanced base, holding 100 days of dust, refilling water, washing mops, and hot-air drying pads. The Roomba 104 self-empties for 75 days but requires bag replacement and lacks the comprehensive mop maintenance features.
How do they handle carpets while mopping?
The DREAME L40s Ultra CE features a mop self-raising function, lifting pads 10.5mm on carpets to prevent wetting. The iRobot Roomba 104 also automatically avoids carpets when in mopping mode, ensuring your rugs stay dry. Both protect carpets from moisture effectively.
Which robot vacuum has better battery life?
The DREAME L40s Ultra CE offers a longer battery life of 160 minutes, compared to the iRobot Roomba 104's 120 minutes. This provides the DREAME unit with extended cleaning cycles before needing to return to its charging dock.
