Pros
  • Plumbed 249 mm dock with the refill and drain kit in the box
  • Legs for a 4.2 cm sill or a 6 cm double step, LiDAR retracted to 89 mm
  • The dock empties for 100 days, washes at up to 80 °C, dries and refills
  • Solid-state 3D sensing with no turret: 80 mm tall and still maps in the dark
  • Leaves the mop on the dock for carpet and lifts the chassis over 30 mm of pile
  • 36,000 Pa with a fully anti-tangle brush and an extending side brush
Cons
  • Needs a water connection and a drain, and the kit has to be fitted
  • 20,000 Pa, under half the 42,000 Pa of the X60 Pro Master on the same kind of dock
  • No noise figure or robot tank size published
  • Roborock publishes neither the dustbin nor the water tank capacity
  • One year of warranty
  • No plumbed drain: the dirty-water tank is still emptied by hand
Best for
  • Homes where the dock can stand by a water connection and a drain, in a kitchen, bathroom or on a balcony
  • Owners who never want to fill or empty a water tank again
  • Homes with a mix of hard floors and carpet
  • Low furniture that a LiDAR turret cannot fit under
