Overview
Not a single brush robot, this dreame model pairs a TriCut brush that slices long hair with a liftable rubber brush for crumbs and litter. MopExtend reaches edges, and AI obstacle avoidance steers around cables, socks and shoes.
Handling hair and large debris equally well is the reason to choose the dual brush setup. The listing has no specs table, so weight, runtime and dock size are unknown.
Who it's for
Homes with long haired pets and kids who spill cereal will use both brushes. Shoppers who compare battery runtime will find it missing.
Pros and cons
- Two brushes for hair and debris
- Cuts long hair to prevent tangles
- Long dust disposal interval
- Obstacle avoidance with AI
- Runtime not listed
- Wash temperature stated two ways
- Single band Wi-Fi
Performance notes
Pickup depends on choosing the right brush: the TriCut blade slices hair while the rubber brush lifts debris from gaps. Obstacle avoidance uses AI depth sensing to route around small objects. The dock washes and hot air dries mops after each job.
