【Large Capacity Battery & Long Continuous Use】This bath cleaning brush is equipped with a large-capacity 5000mAh battery (2500mAh x 2). Each battery charges in about 2 hours and allows for continuous use of up to approximately 248 minutes in low-speed mode. Unlike typical electric brushes that cannot be used while charging, this product allows you to remove the batteries and charge them separately, so you can use one while the other is charging. You can clean without interruption, allowing for more comfortable and thorough cleaning. 【High Output & Smart Display】Achieves power far exceeding that of typical handheld scrubbers. The cordless cleaning brush features three-speed modes: 300/400/600 RPM, allowing you to clean effectively according to the type of dirt. Furthermore, the smart display allows you to check the power mode and battery level at a glance, providing more comfortable cleaning control. 【IPX7 Waterproof & Multi-functional Design】A portable cleaning tool with 5 types of interchangeable brush heads, allowing you to use them freely according to your needs. For example, use the non-woven abrasive pad to remove oil stains, the flat brush to clean sinks, the sponge brush to polish glass, and the stainless steel brush to thoroughly remove stubborn stains from pots and stoves. The extended crevice brush is particularly practical, easily cleaning dirt in corners, grooves, the base of faucets, and the edges of bathtubs, areas that are difficult to reach with typical electric brushes. Furthermore, the brush head portion is upgraded to IPX7 waterproof specifications, so you can use it with confidence even when submerged in water. (※The main body is not waterproof) 【Full Set & High Quality】This set includes 1 handheld scrubber body, 2 batteries, 1 charging cable, and 5 types of interchangeable brush heads, which can be used for various household cleaning scenarios. With its exquisite packaging, it is perfect for home use as well as a gift.
