Dear Sir/Madam I hope this letter finds you well. This is Gary Yu from Sungreat in China. I am excited to share some great news with you. Here are some key features and benefits that make our cleaning brushes stand out:1)Dry/Water mode.Our cleaning brush is equipped with a water outlet. When the water pump is put into the water, it can automatically water out without watering. The water washing function can better clean the solar panels and improve the power generation efficiency.2)Scalable. The length of our cleaning brush can be adjusted from 3.5m to 7.5m, and the length of the brush rod can be adjusted according to your needs, which is simple to operate.3)Automatic rotation.The rotating brush head has its own weight, which can increase the friction between the brush and the solar panel, remove stubborn stains more easily, save manpower and improve work efficiency. Some people worry that rotating the brush head will affect the control of the brush,our brush head speed is determined after continuous testing and adjustment, which can ensure your control of the brush under long-distance use.Compared with the traditional brush, it can effectively improve the efficiency by 185%.4)Unique Buoyancy Design: Our cleaning brushes are specifically engineered with a unique buoyancy design, making them lightweight and incredibly easy to use. This innovative feature ensures that even women or elderly individuals can effortlessly clean solar panels or any other surfaces that require meticulous attention.
