Can I run my robot mower at night?
At night, better not. Robot mowers aren't named explicitly in the 32nd BImSchV, but they count as garden equipment: in residential areas they may run weekdays 7am–8pm — not at night and not on Sundays or public holidays. During night-time quiet hours (10pm–6/7am) no disturbing noise may carry outside. Many municipalities additionally ban night operation on animal-welfare grounds — nocturnal hedgehogs are often badly injured by robots. Injuring a hedgehog can trigger proceedings under the Animal Welfare Act.
📋 The rules
- Robot mowers count as garden equipment — run weekdays 7am–8pm
- Mowing in residential areas is banned on Sundays and public holidays
- During night quiet hours (10pm–6am) no disturbing noise outside
- Many municipalities ban night operation to protect hedgehogs
- Local by-laws, house rules and the TA Lärm can be stricter than the federal rule
🔓 Exceptions
- Very quiet units far from the boundary: usually fine during the day
- Purely private plots with no daytime disturbance to neighbours
- Commercial/industrial zones have different quiet hours
⚠️ Penalties & fines
Noise at the wrong time is an administrative offence; depending on the state immission-control act, fines run from a few hundred to several thousand euros. Repeated night disturbance lets a neighbour sue for an injunction. If the device injures or kills a hedgehog, that can breach the Animal Welfare Act or nature-conservation law (fine, in extreme cases prosecution).

❓ Frequently asked
Can my robot mower run at night?
Better not. In residential areas the quiet hours for garden equipment apply: weekdays 7am–8pm. Night and Sunday mowing is off-limits, and many municipalities expressly ban night operation to protect hedgehogs.
Why is night operation a problem?
Hedgehogs are nocturnal and curl up when threatened instead of fleeing — robot mowers then injure them badly. That's why many municipalities ban night running. Injuring a hedgehog can breach the Animal Welfare Act.
When may I run the mower?
On weekdays between 7am and 8pm, as long as no neighbour is unreasonably disturbed. On Sundays and public holidays mowing in residential areas is banned outright — even for quiet robots.
What could happen to me?
Noise at the wrong time is a fineable offence, and a neighbour can sue for an injunction. If a hedgehog is harmed, you may also face proceedings under animal-welfare or nature-conservation law.
Does this apply in my own garden?
Yes. The quiet hours protect the neighbourhood, not just rented flats. Even in your own garden you must observe them — though with very quiet units set back from the boundary, daytime use is usually fine.
