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
  • Five-axis arm lifts socks, slippers, tissues and small toys out of its path
  • Solid-state 3D sensing with no turret, in an 80 mm body
  • Mops lift, and come off entirely for carpet while the chassis rises and suction boosts
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
  • 22,000 Pa, well under the Saros 20's 36,000, at a higher price
  • No threshold height, bin or tank capacity on Roborock's page
  • The dock does not refill the water tank
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
  • Households with children or pets, where the floor is never quite clear
  • Low furniture that a LiDAR turret cannot fit under
