What the words in my tables mean

Real-time kinematic positioning. The mower uses satellite signals plus a correction signal, which places it much more precisely than ordinary GPS. That lets it follow a map of your lawn without a wire.

RTK where the correction signal comes over the internet from a network of base stations, not from an antenna in your yard. It needs a data connection. Segway says the i210 AWD needs no antenna where its service has coverage.

Segway calls it Network RTK; Mammotion calls it NetRTK. From navimow.com, i210 AWD product page, checked Oct 20, 2026.

Linked from Robot mowers: “Network RTK service”, “Antenna”.

A sensor that measures distance with pulses of laser light, so the robot can build a 3D picture of what’s around it.

“360° LiDAR” is Mammotion’s wording.

Linked from Humanoids: “Sensors” where the maker’s value names it.

The robot uses cameras to see where it is and what’s in its way.

Husqvarna’s own name for its wire-free navigation. With the Automower 410 iQ, Husqvarna includes an EPOS reference station (an antenna you set up) in the box.

Husqvarna’s term. From husqvarna.com, Automower 410 iQ product page, checked Oct 20, 2026.

A wire pegged down or buried around the lawn’s edge, which a mower follows to know where to stop. Of the mowers I list, only the Husqvarna Automower 410 iQ can use one, and it can also work without it.

A motor drives every wheel, not just the back ones. “Rear-wheel drive” means only the back wheels are driven.

Linked from Robot mowers: “All-wheel drive”.

The largest lawn the maker says the mower can look after, in acres. 1 acre is 43,560 sq ft. Where a maker sells several sizes, each size has its own figure, and “Will it suit my yard?” on Robot mowers matches the largest size sold. It’s the maker’s own maximum; makers don’t all say what conditions it assumes.

Linked from Robot mowers: “Lawn area”.

The steepest lawn the maker says the mower can handle. 100% is 45°, and 50% is about 27°. Makers give %, degrees or both, and I show their units.

Linked from Robot mowers: “Max slope”.

The robot has its own mobile data connection, so the app can reach it away from your Wi‑Fi. Some makers charge for the data after a free period.

Connect+ is Segway’s name for its 4G plan.

Linked from Robot mowers: “Mobile data”, “Subscription”.

Pascals, a unit of pressure. Makers quote suction in Pa, but each measures it its own way, so the figures don’t compare across brands and I never rank by them.

Linked from Robot vacuums: “Suction”.

A dock that sucks the dust out of the robot’s bin into a bag or container in the dock, so you empty it less often.

Linked from Robot vacuums: “Self-emptying dock”, “Empties its own bin”.

A salt pool makes its chlorine from salt dissolved in the water. ppm (parts per million) measures how salty the water is. “Safe below 5,000 ppm” is the maker saying the robot can be used in water up to that salt level.

Linked from Pool robots: “Saltwater-safe”.

The band where the water meets the pool wall.

Linked from Pool robots: “Cleans”.

Cordless runs on its own battery. Corded is powered through a floating cable from a power supply at the pool’s edge.

Linked from Pool robots: “Power”.

Glass with no raised frame round its edge, such as a balustrade or shower screen. The robot can’t stop against a frame, so it has to detect the edge itself.

Linked from Window robots: “Frameless glass”.

The smallest window the maker says the robot can clean.

Linked from Window robots: “Smallest pane”.

ECOVACS’ base unit for its OMNI WINBOTs. It stores the robot, powers it and anchors its cable. On the WINBOT W3 OMNI it also washes the pads.

ECOVACS’ term. From ecovacs.com, WINBOT product pages, checked Oct 30, 2026.

Linked from Window robots: “Station”.

How long the maker says the robot stays stuck to the glass if the power is cut, running on a backup battery.

Linked from Window robots: “Holds on without power”.

My status for a humanoid sold to developers and researchers to program and build on. It’s a platform, not a finished home helper. You can order one today.

Linked from Humanoids: “Status” where the maker’s value names it.

You can order or pay a deposit now, but the maker hasn’t started deliveries. Any delivery date is the maker’s estimate.

Linked from Humanoids: “Status” where the maker’s value names it.

Orders go through the maker’s sales contact form. There’s no public order button.

The maker takes reservations through a contact form. There’s no public order button.

The maker takes names for a waitlist only: no deposit and no order.

The maker is running a beta in homes before it sells the robot. Sunday Robotics’ beta is free.

Shown publicly by the maker, with no way to order it.

Whether the maker says the robot does tasks with no person controlling it. “With remote help” means the maker says a person may take over remotely.

Linked from Humanoids: “Works on its own”.

A person steers the robot from somewhere else, seeing through its cameras. 1X calls its operators “Experts”: 1X employees in the US, in sessions you schedule and accept. Weave says “teleoperation assistance when needed”. Fauna lets the owner pilot the robot.

“Experts” is 1X’s term. From 1x.tech, Weave’s and Fauna’s sites, checked Oct 21, 2026.

Linked from Humanoids: “Remote operators”.

The number of separate ways the robot’s joints can move. Makers count them for the whole body or per hand.

Linked from Humanoids: “Joints”.

A hand whose fingers move on their own, as opposed to a gripper or no hand.

Linked from Humanoids: “Hands”.

The weight the maker says the robot can lift or carry, often per arm.

Linked from Humanoids: “Payload”, “Arm payload”.

Whether the robot’s AI runs on its own computer or on the maker’s servers over the internet.

Linked from Humanoids: “On the robot or in the cloud”.

Software development kit: tools for writing your own programs for the robot.

Vision-language-action model: AI that takes in camera images and instructions and turns them into the robot’s movements.

“OmniSense VLA” is SwitchBot’s own model. From SwitchBot’s site, checked Oct 21, 2026.

Linked from Humanoids: “AI”, “AI inside” where the maker’s value names it.

A two-digit code for protection against dust (first digit) and water (second). Higher numbers mean more protection.

Linked from Humanoids: “Safety design” where the maker’s value names it.

A code the US Federal Communications Commission issues for a device with a radio (Wi‑Fi, Bluetooth, mobile data) before it can be sold in the US. It shows the radio was approved. It says nothing about electrical or fire safety.

Linked from Every robot page: “FCC ID”.

Marks from three testing labs (UL Solutions, Intertek and CSA Group) that the US safety agency OSHA recognises to test products against US safety standards. A listing means that model was tested for electrical and fire safety.

Linked from Every robot page: “UL”, “ETL (Intertek)”, “CSA”, “Nothing else found”; Humanoids: “Safety certifications”.

The US Consumer Product Safety Commission (CPSC) announces a recall when a product has a hazard and the company agrees to a repair, replacement or refund.

Linked from Every robot page: “Recalls”.

A CPSC warning about a product that hasn’t been recalled, usually because the company hasn’t agreed to a recall.
