How to choose
Suction and runtime
Suction and runtime decide how much floor a robot covers on one run. The ILIFE pairs 10,000Pa suction with a 150-minute runtime, the DREAME pairs 25,000Pa suction with a 231-minute runtime, and the roborock pairs 20,000Pa suction with a 253-minute runtime. The DREAME covers 1679 ft² in Quiet Mode. All three take app and voice control, so compare suction and runtime against the floor area you clean.
Mapping and obstacle avoidance
Mapping lets a robot plan routes room by room instead of wandering, and obstacle avoidance keeps it clear of shoes and furniture. The ILIFE uses LiDAR navigation with home mapping and No-Go Zones, and the roborock uses LiDAR with Quick Mapping and a 3D Map Display. The DREAME maps your home with precision and avoids obstacles with Smart Pathfinder and 3DAdapt. Pick the mapping style that matches the rooms and obstacles in your home.
Self-emptying docks and mopping
A self-emptying dock means fewer dustbin empties by hand, and mopping adds a wet pass after vacuuming. The ILIFE station holds 2.2L with 5 dust bags. The DREAME all-in-one dock cleans itself, and the roborock dock empties dust, refills the water tank, cleans the mop at 149°F, and dries it with 113°F warm air. The DREAME and roborock mop as well as vacuum, with extendable mops for edges and corners.
