Product recall: Husqvarna robot lawn mowers pose ‘a fire hazard’

A safety notice issued by the Office for Product Safety & Standards (OPSS) identified two models of robotic lawn mowers from manufacturer Husqvarna as “possibly a fire hazard due to charging pattern”.

Husqvarna’s Automower 435X and Automower 535 are the two models in question, responsible for five reported incidents where they caught fire while their batteries were being charged.

The OPSS also declared that these products failed to comply with the requirements of the Electrical Equipment (Safety) Regulations 2016, forcing Husqvarna legally to fix the issue.

Husqvarna is in the process of contacting product owners directly to arrange a replacement battery through its dealer network.

The company is also addressing issues caused by the charging model by releasing two mandatory software updates for affected models. These updates can be installed through Husqvarna’s Firmware Over the Air technology, or your local dealer who stocks Husqvarna models, and should extend battery life and resolve degradation issues.

How do robot lawn mowers work?

A robot mower

Robotic lawn mowers allow you to forget about mowing the lawn and, depending on the model, can cope with complex layouts and sloping lawns.

They work by mowing your lawn within a perimeter defined by perimeter wires. They also have a docking station, which they return to after each mowing session to recharge the lithium-ion battery. The perimeter wire, which allows them to detect the boundaries of your lawn, begins and ends at the charging station; this causes a small current to pass through the wire and creates an electromagnetic field which the trimmer can sense to keep it within its defined area.

It may sound quite scientific and technical, but in practice all you have to worry about is laying that boundary wire by hand and then securing it or burying it a few inches deep. (Some companies offer to do this service for you.) Once set up, your job should be fairly easy – the robot mower will power up and get to work on a schedule you determine, before returning to its charging station to recharge before. the next cut.

The way it roams around your yard between rests in its kennel-like charging station makes a bit of a robot mower the handiest and most useful pet you can have – and best of all, you don’t have to clean up after them. They cut the grass so finely that the clippings essentially melt into the ground, ensuring a nice tidy look in addition to providing the grass with nutrients.
