Pros & cons
Shark AI Ultra 2-in-1
- ✓Large 500ml dustbin means fewer empties between self-empty cycles
- ✓Widely available at Target, Walmart, and Costco with easy returns
- ✓LiDAR navigation creates accurate maps quickly
- ✓Self-empty base is smaller and more compact than many competitors
- ✓Good US-based customer support
- ✗Mopping is basic — passive drag-style, no spinning or pressure
- ✗No obstacle avoidance means it bumps into furniture and cables
- ✗Shark app is functional but clunky compared to Roborock or Dreame
- ✗No mop lifting — mop pad must be removed for carpet-only cleaning
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
- ✗Dock takes up serious floor space and the water tanks need weekly attention
- ✗Dreame app notifications are chatty out of the box
- ✗Frequent sale-price swings make it easy to overpay — wait for the $600s
