Keeping a robot mower from walking off: PINs, GPS tracking and insurance

How real is the risk?

No reliable public figure exists for how often robot mowers are stolen, and the manufacturers who comment on it have an interest in reassuring buyers. Husqvarna's support page calls reported thefts relatively rare. Belrobotics, which makes commercial mowers, argues that a stolen robot is of little use to a thief because its charging station has to be installed and activated by a technician. Still, Mammotion's own security guide puts typical robot mower prices at US$1,000 to $4,000, and a machine like that sitting on a visible dock all summer is an obvious target.

Recovery stories show what the technology can do when it's set up properly. In 2020, the Martha's Vineyard Times reported that police on the island tracked a stolen Husqvarna 435X, listed in the police report at about US$5,199 retail, to a contractor's van using the mower's GPS. The owner then set off the mower's alarm remotely so officers could hear it inside the vehicle. That recovery depended on three things being in place before the theft: GPS, a data connection and an alarm the owner could trigger.

Layer one: the PIN and the alarm

Almost every current robot mower can be locked with a PIN. Husqvarna says an Automower can't be used without its code. If the code isn't entered within 30 seconds of pressing STOP, an alarm sounds, and lifting the mower sets it off immediately. Some models add a time lock that asks for the PIN at an interval you choose, and the mower is paired to its own charging station so it won't work with another one. Segway's anti-theft explainer says a Navimow's high-decibel siren keeps sounding until the PIN is entered, even if the mower is switched off, and that a lift alarm triggers after the mower is held up for a few seconds.

Pick a real code. Mammotion's security guide specifically warns against defaults like 1234 or 0000. And be realistic about alarms. The UK enthusiast site The Robot Mower points out that a pickup alarm only helps if someone is close enough to hear it, and thefts tend to happen when nobody is.

Layer two: GPS only helps if it can phone home

A tracker matters only if the mower can report its position once it has left your Wi-Fi. Husqvarna says its X-line models include a GPS unit that powers a geofence and lets you follow the mower's movements, while most other models need the Automower Connect kit as an accessory. Among current models in our coverage, the Husqvarna Automower 410 iQ (Husqvarna Automower 410 iQ review) and 420 iQ (Husqvarna Automower 420 iQ review) list PIN, alarm, geofence and GPS theft tracking, along with cellular connectivity.

Segway's page says budget Navimow models need the Access+ 4G module to enable anti-theft tracking, that the geofence radius is adjustable from 10 to 50 m, and that Navimow also works with Apple's Find My network. It also says cellular data is charged after an initial free period, though a sidebar on the same page describes data as free. Ask the retailer or Segway which applies to your model. The Navimow i110N (Segway Navimow i110N review) treats Access+ as optional, while Mammotion advertises built-in 4G with an included period on the LUBA mini 2 AWD (Mammotion LUBA mini 2 AWD 1500 review). Whichever you buy, find out what the connection costs after the free period, because a lapsed plan means no tracking.

Layer three: placement and habits

The cheapest deterrent is not being seen. The Robot Mower suggests placing the charging station out of sight of passers-by and hard to reach from outside the property, lighting it with a motion-sensor light, and considering a mower garage that hides both the robot and its power supply. Sunseeker's theft guide adds bolting down the charging station, scheduling mowing for when someone is home and bringing the mower in overnight.

Record the serial number and register the mower with the manufacturer as soon as it arrives. Mammotion recommends this, and the serial is the first thing police, dealers and insurers will ask for. A photo of the label stored off the device takes a minute.

In Canada, the off-season helps. Once the mowing season ends, the mower and any removable station parts can come indoors, which removes them from view for months. The guide to storing a robot mower through a Canadian winter (robot mower winter storage canada) covers that seasonal routine in detail.

Insurance: ask before you need it

Husqvarna and Belrobotics both say many home insurance policies cover robot mowers, and both tell owners to check their own policy. That caveat matters. The Robot Mower's author describes a UK insurer refusing to cover the mower and having to switch policies, and found that outdoor-contents limits varied widely between insurers. That's one owner's experience in another market, but it shows that cover can't be assumed.

In Canada, consumer insurance site MyChoice notes that home policies often set lower sublimits for theft of certain categories of property and for property in storage. Rather than guess, ask your own insurer or broker a few direct questions. Is a robot mower covered while it's outside on the lawn? Is there a limit for outdoor property? Does storage in a locked shed or garage change anything? How does the deductible compare with what the mower would cost to replace? Get the answers in writing, and keep the receipt, model and serial number with your home inventory.

If it goes missing

Husqvarna's theft checklist starts with a police report and its case number, then a report to your dealer with the serial number, model, the date it went missing and whether the charging station was taken too. Dealers can then flag the unit if it turns up for service. Sunseeker's guide adds a remote lock from the app, screenshots of the last known location and movement history for police and your insurer, and a request to the manufacturer to blacklist the serial number.

One piece of advice from Sunseeker is worth repeating: if the app shows where the mower is, give that location to the police rather than going to get it yourself.

From a tech standpoint

Anti-theft features work in layers, and the layer that gets a mower back is the one most often left unfinished: a GPS unit with a live data connection. Set the PIN, turn on the lift alarm and geofence, keep the dock out of sight, and make one phone call to your insurer before the season starts. That way you'll have a plan before you ever have to use it.
