From Hibernation to the Slopes: Avoid 5 Robotic Lawn Mower Mistakes in April

For garden enthusiasts, April marks the start of the season. The grass seems to grow inches per hour, and the temptation is great to simply retrieve your trusty robotic lawnmower from the basement, place it on the charging station, and press "Start."

But beware: The transition from winter storage to the lawn is the most critical phase in the life of a robotic lawnmower. Those who are careless here risk not only an uneven cut but also expensive hardware damage.

To ensure your automatic helper doesn't have to go to the workshop in May, here are the five most common mistakes at the start of the season – and how to avoid them.

Mistake 1: "Shocking" the battery with cold

Many store their robotic lawnmower in the garage or garden shed. Even if it's mild during the day in April, nights can still be frosty.

The problem: Lithium-ion batteries hate cold. If you start or charge the robot at temperatures near freezing, the cell structure can be permanently damaged. Capacity drops rapidly, and the robot can no longer complete its usual routes.

• The solution: Wait until ground temperatures are consistently above 10°C before the first use. Before the first start, store the robot in a heated room for 24 hours so that the battery reaches room temperature.

Mistake 2: Dull blades as "grass killers"

A robotic lawnmower doesn't cut grass like a conventional mower – it shaves it. If the blades from last autumn are still installed, they are certainly dull or corroded by fertilizer residue.

The problem: Dull blades tear the grass blades instead of cleanly separating them. The result is frayed, white grass tips that make the lawn appear brown and make it susceptible to diseases.

Pro Tip: Always start the season with sharp blades. High-quality replacement blades for all common models can be found directly in our shop: Buy robotic lawnmower blades now.

Mistake 3: Underestimating the "jungle shock"

The lawn is often quite high in April. Sending the robot directly into 10 cm high grass overstresses the mechanics.

The problem: Grass that is too high causes cuttings to accumulate under the housing. The mowing motor has to work extremely hard and can overheat.

• The solution: Make the first cut with a classic mower or set the robot's cutting height to maximum on the first day and gradually work your way down.

Mistake 4: Neglecting the charging station and cable check

Over the winter, moisture and rodents in the garden can have done a lot of damage.

The problem: Corroded contacts prevent efficient charging. A small bite from a mouse on the boundary wire leads to unreliable driving behavior or error messages.

• The solution: Clean the charging contacts with fine sandpaper or contact spray and check the LED on the charging station for a stable signal.

Mistake 5: Ignoring the "hedgehog danger" in spring

In April, hedgehogs awaken from hibernation and are often still very slow.

The problem: Robotic lawnmowers often do not detect small obstacles in time. Since hedgehogs do not flee when in danger but roll up, accidents are common in spring.

• The solution: In April and May, never program your robotic lawnmower for night work. Only let it run between 9:00 AM and dusk.

Conclusion: A gentle start saves money

Your robotic lawnmower is a high-performance device. If you take the time in April for a quick check and new blades, your lawn will be the envy of the neighborhood in summer.

Good luck with the start of the 2026 season!
