However, you can add additional functions and take greater control over the mower using an app on your smartphone. This lets you start and stop the mower remotely (though it only supports Bluetooth, so you still have to be in the vicinity). More crucially, it lets you control exactly when the robot should head out for a run, with two programmable mowing slots available for each day of the week, so you can really fine-tune your mowing. Add in a solid app that keeps an eye on the weather and schedules mowing times accordingly, dodging any days when you’d rather keep the lawn free from robot activity, and you’ve got one of the most intelligent robot lawn mowers around. Instead of randomly bouncing around your garden like more affordable robot mowers, the Bosch then works in stripes, efficiently starting at one end of the garden and mowing in lines until it’s all done. This doesn’t give you the same stripey lawn you’d expect from a mower with a roller, but some striping is still visible when it’s finished. More importantly, it hasn’t endlessly trundled over the same bits of lawn, so there’s much less wear and tear than we’ve seen with robot mowers that move randomly.

Rain detection: It’s better to let your grass soak up excess moisture before mowing it. A rain sensor will send your robot home if it starts to rain, and can delay mowing until it’s dry again. Installation: Installing a robotic mower is not difficult, but might be a cumbersome task in case of big lawns. All the autonomous mowers come with clear instructions that you can follow and finish the setup.The mower can move over an inclined path up to 8.5 degrees. To be honest, it’s not a great angle to cover because several other models can cover anything between 20 to 35 degrees. If you own a flat lawn, then there is no need to consider the inclined movement. However, if the garden has some high slopes then you should look at other options present on this list. If you service a robotic mower every year and don’t damage its housing, the life expectancy is up to 10 years. The battery adds to the operational cost because you need to replace the cells anywhere after 3 to 6 years; depending upon the make and model. Price range: Autonomous mowers are not affordable when compared to other versions. However, entry-level models are available at comparatively lower prices when compared to high ends options. No matter what is the price tag, you need to make sure that the machine can cover your lawn. There is no point spending on a tool that cannot maintain your garden properly.

Edge cutting: No robot mower can edge your lawn as well as you can but some can trim closer to your flower beds than others. To reduce secondary mowing, look out for models with offset blades. Unfortunately, all this innovation does come at a cost, since this is one of the priciest robot lawn mowers you’re likely to find on the market. Still, if you have a large lawn that you want neatly trimmed but you don’t want the hassle of laying wires, it’s certainly an effective option. All the robot mower draws power from a rechargeable lithium-ion battery that lasts between 3 to 6 years. The running time depends upon the make, model and the mowing conditions. Bottom Line Robomow RX12U is unique because it doesn’t have the common three-wheel movement. Instead, it has two wheels and a glider that provides you with better maneuverability. Such an arrangement gives it much more freedom and hence it’s one of the best robotic lawn mowers for complex areas. When it comes to actually mowing the lawn, the Bosch Indego S+ 500 is one of the best we’ve tested. The first time you mow, the Bosch travels around the perimeter wire to create the map of the area, which is stored in the robot’s memory. It cuts as it goes, ensuring you’ve got a solid perimeter cut as it goes.
