Pros & cons

- ✓5300Pa suction handles daily cleaning on hard floors and low carpet well
- ✓Long battery life covers large homes comfortably
- ✓Auto mop lifting keeps carpets dry during combined vacuum+mop runs
- ✓Dreame app has improved significantly with regular updates
- ✗No camera-based obstacle avoidance — bumps into small objects
- ✗No hot water washing — mop pads need occasional manual cleaning
- ✗Mopping is adequate but not as thorough as higher-end models
- ✗Dustbin is small at 350ml, relies heavily on auto-empty to compensate
Dreame L40s Ultra
- ✓Flagship-grade 19000Pa suction and hot water mop washing at a mid-range price
- ✓81% positive sentiment on r/RobotVacuums — praised for obstacle avoidance and pet hair
- ✓DuoBrush design shrugs off long hair that kills single-roller robots
- ✓MopExtend reaches baseboards and into corners most round robots miss
- ✓260-minute battery covers large homes in a single run
- ✗Carpet performance is good but not class-leading — fine dust stays in thick pile

- ✗Dreame app notifications are chatty out of the box
- ✗Frequent sale-price swings make it easy to overpay — wait for the $600s
