FAQ
What type of grass are these electric mowers best suited for?+
These models work well on typical UK lawns, including mixtures of fescue, rye, and bluegrass. They're particularly effective with shorter grasses and won’t damage longer, coarser varieties as much as petrol alternatives.
How often should I charge the battery (if applicable)?+
Most models come with a rechargeable battery. Charge it after each use to ensure optimal performance. A fully charged battery typically provides 30-60 minutes of runtime depending on the grass length and mower speed.
What safety precautions should I take when using an electric lawn mower?+
Always wear appropriate eye protection and sturdy footwear. Never operate the mower near water sources, and ensure children are kept a safe distance away. Regularly check blades for damage and keep fingers clear of moving parts.
How do I empty the 40L grass box?+
Simply tilt the mower back slightly and tip the grass box out into a suitable waste container. Ensure the lid is securely fastened to prevent clippings from spilling during use.
Are these mowers easy to store?+
Their compact size makes them relatively easy to store, often in a garage or shed. Consider purchasing an optional storage bag for added protection against dust and dirt.
What is the typical battery life of these electric lawnmowers?+
The runtime varies depending on the specific model and grass length, typically ranging from 30 to 60 minutes on a full charge. Check the product specifications for precise details.
Can I use these mowers on uneven ground?+
While they're relatively easy to maneuver, it’s best to avoid extremely uneven terrain. Slightly sloping lawns can be managed with caution, adjusting speed accordingly.
What kind of maintenance do these electric lawnmowers require?+
Regularly clean the blades and housing with a damp cloth. Periodically check the battery charge level and store it correctly when not in use – ideally at room temperature.
Are there any specific accessories I should purchase?+
Consider purchasing an extension cord for convenient charging or a grass collection bag to improve clippings containment. A blade sharpening kit can also extend the life of your blades.

Electric mowers are significantly quieter than traditional petrol models, typically operating at around 80-90 decibels. This makes them a more considerate option for neighbours and reduces disturbance.
