What to look for when choosing

The most popular and sought after brands of lawnmowers and robots are Bosch, Unisaw, Husqvarna, Gardena, Caiman, Wiper, Robomow, Viking, Wolf Garten on the Russian market. Type of battery. Inexpensive models are equipped with a lead-acid battery, but most cars have a lithium-ion battery. It has a high reload speed, there is no “memory effect" and self-discharge.

Lithium-ion batteries are divided into lithium-cobalt (500 cycles), lithium-manganese (up to 1000 cycles) and the most modern. lithium-iron-phosphate with a large number of recharge cycles (up to 2000) and increased operational safety. Some models are equipped with a solar battery in addition to the battery. Processing area. It ranges from 400 square meters. m up to 5000 square meters m. On a lawn with slopes and obstacles, the productivity of equipment decreases. in such cases, it is better to take a model with a small margin in processing area. Operating time without recharging. It can be from 45 minutes to 5 hours. The method and time of recharging.

The machine can connect to the charger manually or automatically when it returns to base with a low charge level. The time depends on the type of battery and ranges from 45 minutes to 20 hours. Mowing speed varies from 16 to 30 m / min. It affects not only the speed, but also the quality of the haircut. Cutting height adjustment. Some models have a fixed height, while others have the ability to adjust it between 20 and 80 mm. Type of cutting system. There are two main types: blade knives (even handle hard grass) or a disk with “floating” double-sided knives, which provides a more delicate haircut.

The speed of rotation of the knives on some models can reach 6000 rpm. It is better if it is automatically adjusted: but with an increase in the load on the knives (for example, wet grass), the machine reduces the number of revolutions of the knives, or even stops. This protects the device from quick wear and tear. The mowing width varies from 17 to 84 cm. The larger it is, the less the robot has to go in order to complete the work.

Size and arrangement of wheels. For a smooth lawn, a model with driving rear wheels is enough. The front wheels (one or two) of such machines rotate freely, providing the device with maneuverability. For more effective work on slopes and bumps, there are all-wheel drive robotic mowers with four independently working wheels. They have higher traffic, but more energy consumption. A way to define boundaries. Economy models adhere to the lawn with obstacle sensors. When encountering a curb or wall with a height of more than 10 cm, the machine changes direction. For such a robot, you will have to enclose the lawn with at least a decorative fence, and this is not always convenient and aesthetically pleasing.

Some models, in addition to obstacle sensors, have grass sensors and mow only in areas where grass touches the bottom of the chassis. When driving onto a track or bald spot, the robot changes direction. Similar models are intended mainly for small lawns (up to 800 m2), and their main drawback. low quality cutting edges. The installation of a restrictive fence near a reservoir, pits and other similar obstacles is necessary.
