Steer clear of ...

because just after 2 years - the end of the warranty period - an "electrical problem" occurred. I brought the instrument to the dealer and reclaims the device and obtain the information, the robot was hosed and all electronic internal parts are corroded. Furthermore, it was claimed that the device would have a rain sensor and should go when it rains in the charging station. The repair would cost about 800 euros, corresponding to a new device.

In fact, no pond, no puddles, no clean water. Only the previous summer was very rainy and therefore rain, the unit has shut down. In the manual nowhere an indication that rain would be a problem. When the device is about mowing idea: "... R40 Li can even mow in the rain, wet grass easily collects on the mower remains ...". Only at point Installation of the charging station: "The location must before splashing, eg from lawn sprinkler, be protected."

The mowing result, however, was very satisfactory, so I went in search of a rain-resistant device. In short, there is no. Husqvarna - Gardena belongs to - indeed offers an allegedly weatherproof Mower, however, is the expensive just around corners! and weatherproof, is not waterproof.

So I let myself be carried away to the builders merchants the confidence to buy in sales again, the same model, probably to avoid the reinstallation also to me.
Unpacking the unit and connected, and now comes the Hammer: message when device "charge current too high"! This has the result that the device does not load and thus is not ready for operation. Did it again complained and to get information that an incorrect transformer was enclosed. The zoom is now available for exchange.

Because it really makes Gardena easily and as a result, I can only advise every before buying!
