Maybe you’ve already experienced the magic of a robot vacuum cleaner, and are familiar with the benefits of owning a robotic machine to help around the house. Or, perhaps you’re just curious about robot lawn mowers and want to learn more. These machines tend to cost a bit more than your average robot vacuum cleaner, but enthusiastic owners agree that the convenience and amount of time saved by having a robot lawn mower do the work is worth the initial cost.

You’ll find a relatively broad range of prices, and for good reason. In general, the less expensive models tend to be more compact, and are best suited for gardens and other small spaces. Some are better for maintaining grass once it’s cut, rather than for tackling overgrown lawns. On the other hand, you can find larger and more powerful mowers that perform more like a regular lawn mower. However, the cost of this type of robot mower is often higher.

Aside from price tag and size, many shoppers look for specific features, such as battery life, theft protection and weather resistance. Many robot lawn mowers run on a Lithium-ion battery, which delivers emission-free power and typically requires a relatively short time to recharge. An automatic lawn mower understandably draws a lot of attention, and the thought of letting your mower run free when you’re not home may be troubling. Rest assured that many mowers come equipped with alerts, alarms and built-in PIN codes for added security.

While it’s best not to let the mower continue to operate in harsh weather conditions, some models can tolerate light rain. Even if your mower is designed to remain outdoors in heavier rain, the added moisture can cause issues with blades of grass getting stuck, among other problems. Those that can’t are equipped with a rain sensor, and simply return to their charging base until it’s dry enough to resume mowing.
