Cleaning type Whether the robot vacuums only or vacuums and mops, and any extra cleaning tool in the package. A vacuum-and-mop robot still needs water handling. Read the mop hardware and dock fields before assuming hands-free mopping.	Vacuum and mop with dual spinning mop pads; vacuum-only operation detaches the mop mounts automatically.

Navigation and obstacle sensing The documented mapping technology and obstacle-sensing hardware. LiDAR, ToF, camera and AI are hardware or software names. They do not establish how well a robot avoids a cable or a pet mess in your home.	StarSight Autonomous System 2.0: 3D ToF navigation without a LiDAR turret; obstacle sensing by 3D ToF, RGB camera and VertiBeam lateral sensing.The maker FAQ contrasts this with the retractable LDS used on Saros 10.

Manufacturer-rated suction The suction pressure figure published by the maker, where one exists. Each maker measures this figure its own way. It is a marketing number, not a cleaning result, and some makers publish none at all.	Not verified We have not verified this value. It is not a confirmed no or zero. Check the original source or ask the manufacturer if it affects your choice. The US page names HyperForce suction without publishing a Pa figure.

Mop lifts or retracts on carpet Whether the maker documents lifting, retracting or detaching the mop when carpet is detected. A lift height is a nominal figure. Thick rugs can exceed it, and some robots only lift in a particular cleaning mode.	Yes17 mm mop lift is stated, and the mop mounts can detach for carpet cleaning.

Dock empties the dustbin Whether the dock in the selected package transfers debris from the robot into a bag or container. Package-level fact.

Water handling at the dock How the selected package refills the robot and collects dirty water, with tank sizes where published. Dock tanks are still filled and emptied by hand unless a plumbing kit is part of the package. Detergent dispensing is a separate feature.	Dock refills the robot from a clean water tank and collects wash water in a dirty water tank; both dock tanks are filled and emptied by hand. A cleaning-solution cartridge slot is documented.

Robot body height The published overall height of the robot, including any sensor turret. Compare with the lowest furniture you want cleaned under.

Threshold crossing height The maximum ledge or threshold height the maker claims the robot crosses. A maker figure under its own test conditions.

Claimed runtime The longest published runtime per charge, with the mode and suction setting kept in the note. Runtime claims usually assume the quietest vacuum-only mode. Mopping, carpet boost and recharge-and-resume change the real session.	Not verified We have not verified this value. It is not a confirmed no or zero.

Robot dustbin capacity The published capacity of the dustbin carried on the robot. With an auto-empty dock the onboard bin matters less. Without one, it sets how often you empty by hand.

Questions to check before buying	No measured cleaning, suction, obstacle-avoidance or noise result is established here; names such as StarSight and HyperForce describe hardware and marketing. Height is converted from a design claim because the store's dimension line is garbled; verify furniture clearance against the manual drawing before relying on it.
