Robomow RC 304 U
Product description

The robotic lawn mower Robomow RC 304u is suitable for an area of approximately 500 m2 according to the manufacturer’s recommendations. The area size takes into account the mower’s design parameters. The working area is defined by the boundary wire. The mowing method and the mowing movement is random. Continuous information about already mown area is not available. Robotic lawn mower returns to the charging station along the wire. The cutting width is 28 cm. The range for cutting height adjustment is from 15 mm to 60 mm. The robotic lawn mower Robomow RC 304u can mow the area of the maximum slope of 20 degrees or 36 percent. The motor of Robomow RC 304u is designed with brushes. The battery capacity is 2.4 Ah, which represents the overall energy of 62.4 Wh by the system voltage 26 V. The charging time is approximately 50-70 minutes. The robotic lawn mower with the full charged battery can mow for 60 minutes. The mower weight with the battery included is 11.1 kg.

For easy detection of the slope degree, we recommend using a digital spirit-level when selecting a robotic lawn mower. It allows you to measure the slope in degrees. To make sure that you correctly identify the maximum slope value on your lawn, it is necessary to measure it at multiple locations and take into account the highest value measured.
