1. What Are Cordless Pressure Washers？

Cordless pressure washers can effectively remove dirt and grime. These powerful washers instantly remove dirt that cannot be reached or that you do not want to touch with tools such as hand washing or brushes.
Cordless pressure washers utilize high-pressure water streams to effectively remove stubborn dirt that has accumulated over the years, making them a reliable cleaning tool.

1.1 The Technology of Cordless Pressure Washers:

Battery Technology:

1. Lithium-ion (Li-ion):

Cordless power washers run on Lithium-ion batteries, which generally have a higher power capacity compared to traditional battery types such as NiCad (Nickel-Cadmium). Li-ion batteries can store significantly more energy per unit.

Motor Efficiency:
