Description of robot mower 1) Intelligent moving function Intelligently adjust moving speed according to lawn density, namely reduce moving speed in the areas with sparse grass and increase moving speed in the areas with dense grass and spiraling outwards in the areas with very dense grass. 2) Collision sensor There are collision sensors in front of the IMOWER.When it hits any obstacles, such as a tree or rock, it just reverses safely and selects a new direction before continuing 3)Rain sensors When it gets raining, it will find its own way back to the charging station. 4) Automatic charging IMOWER returns to the charging station when it senses its battery is almost empty. After being charged, it can continue operation according to preset procedure. It will stops in the charging station after it worked for three times and finished the third time charging. If you want it to continue working, you have to start it again. 5) Drive insects away by ultrasonic radar 6) Cutting height adjustment The cutting height is easily adjusted by turning the knob at the top of the mower, no need to touching the wet grassy mowing parts. 7) Blade safety control When people or animal comes closer, IMOWER can automatically stops the blade, and reverses safely and then turn to another direction. The blade will also stop as soon as it was lift up from the ground by any sides. 8) Remote control Realize startup/closedown of the mower, contron the direction, force it to go back to the charging station etc by means of the instruction of remote controller. 9)Theft protection systems The mower has Dual-boot function. It could not be started without the remote control. The buzzer in the machine will alarm suppose it was forced taken away by unauthorized person when it was working or charging. 10) Charging base contains electronic fence Before IMOWER can get to work, you will need to simply staple a electronic fence wire to the perimeter of the lawn. This wire can be sensed by the mower and will ensure that only this area of grass is cut. Once the wire has no power, IMOWER will stop at once, this can prevent it leaving the assigned range.
