The electric rotary shaver is equipped with an advanced lithium battery with a capacity of 2500 mAh, which can work for up to 90 minutes and be fully charged within 3 hours. This shaver has three gears, with a maximum speed of 420 rpm, much higher than the average of other similar products, to meet your different cleaning needs and deal with different levels of stains. 【Digital Display Panel & Voice Broadcast Function】 The built-in digital display allows you to clearly monitor the battery level and select the rotation speed at any time. In addition, KEIMI's upgraded electric cleaning brush rarely introduces a voice broadcast function to help you clearly understand its working status. Our cordless cleaning brush offers 8 multifunctional replaceable brush heads, suitable for different scenarios. For example, cleaning concave surfaces such as bathtubs and sinks, cleaning narrow and hard-to-reach areas such as corners and crevices, and cleaning floors, glass, tile walls, car surfaces, wheels, car seats, furniture and stoves. 【2-in-1 Electric Rotating Cleaning Brush, Handheld and Retractable Function】The bathroom brush has a three-stage design, which can be adjusted from 35.8cm to 110cm. Whether it is the bathtub or the ceiling, you can easily clean it without bending down, which is friendly for the elderly and those with lower back pain. This detachable rod allows you to have a 12 inch (about 30.5cm) handheld electric shaver at any time. It is like having two different electric cleaning brushes. Package includes: 1 * Electric Brush
