The Kärcher RLM 4: a robust companion for your garden
When lawn mowing is fun: The Kärcher RLM 4 is the ideal partner for gardens up to 500 m2. A four-blade system ensures a thorough mowing result. The robotic lawn mower reaches the lawn edge down to a few centimetres (with a cutting width of 20 cm). Specially rubberized wheels allow it to climb gradients up to ± 45 %. Theft protection included: PIN code lock and alarm function ensure security.
Four knives for the perfect cut
With its unique four-blade system, the robot lawn mower ensures a thorough mowing result. While two-sided sharpened cutting blades trim the grass, two clearing blades take care of the dirt in the body of the robot. The robot mower reaches the lawn edge down to just a few centimetres and passes narrow areas with a width of up to 60 centimetres. Even more: The cutting blades of the robotic lawn mower can be mounted in the opposite direction as soon they are worn out and can therefore be used for a longer time.
A small mountaineer with a profile
Small but powerful: The Kärcher RLM 4 can handle gradients of up to ± 45 % without any problems. The rubberized wheels, which are equipped with a grippy profile, are responsible for optimum traction.
Intelligent multi-sensor technology
The robot lawn mower is equipped with collision, tilt, lift and loop sensors. When it rains, an adjustable rain sensor can be used to select if the robotic lawn mower should continue mowing – or drive back to the charging station. Apropos charging station: If the battery is almost empty, the robot mower returns back to its charging station automatically.
Simple operation combined with a high level of safety
Easily installed in your garden
The Kärcher RLM 4 can be put into operation in just a few steps: The robot lawn mower is started and stopped manually via a display and the mowing times are individually determined. One hand is enough to adjust the cutting height (between 25 and 55 mm). The special thing about this is that the cutting height is easily visible at all times because of an integrated magnifying glass.
Don’t give thieves a chance
The robotic lawn mower is not only a professional lawn mower, but can also score points in terms of safety: Choose your personal PIN code and protect your robot lawn mower with the PIN code lock and alarm function.
