Same summary

The 16-liter battery-powered automatic sprayer is suitable for users who need a reliable and mobile solution for spraying in the home garden or smaller agricultural areas. The included battery ensures that the device is immediately ready for use, as there is no need to purchase additional batteries. The 12 V voltage is suitable for occasional tasks and spraying on medium-sized areas, with the trade-off being a slightly shorter autonomy compared to higher voltage models. A brushless motor would be recommended for more intensive use, but this model does the job quite satisfactorily for basic garden tasks.
