Can a robot mower mow in the rain?
Short answer
They're built for it, but makers disagree on whether they should. Husqvarna says its Automower iQ mows rain or shine; Mammotion's Luba 3 AWD detects rain, and Segway's Navimow pauses and heads home when the forecast turns, to protect the lawn from wet grass.
Which robots can do it?
- Husqvarna Automower 410 iQYes
Husqvarna says its Automower iQ mowers operate rain or shine; the 410 iQ is rated IPX5.
Good to know: Maker's claim and rating; IPX5 means protected against water jets, not submersion.
- Ecovacs Goat O800 RTKYes
Ecovacs rates the Goat O800 RTK IPX6 waterproof.
Good to know: Maker's rating, UK site; the page doesn't say whether it mows in rain. A German test noted slight trouble on wet slopes.
- Mammotion Luba 3 AWDYes
Mammotion lists rain detection and IPX6 waterproofing for the Luba 3 AWD.
Good to know: Maker's specs; the page doesn't say what the mower does when it detects rain.
- Segway NavimowYes
Segway says the Navimow i Series watches real-time weather forecasts and, when the weather changes significantly, pauses and returns to its dock to protect the lawn from wet grass.
Good to know: Maker's description, from the European site.
Why it matters
Mowers live outside, so owners want to know whether rain will damage the robot or leave a torn, clumped lawn.
Not proven yet
How each one cuts wet grass in practice, and whether mowing in the rain hurts the lawn over time; no test in our sources compared them in rain.
