The 45 ° rotatable brush shaft, combined with a retractable handle, can clean stains of different heights, such as those in corners. Traditional cleaning methods require long periods of squatting or kneeling on the ground, which can cause knee or waist pain. However, the rotatable brush shaft only needs to change direction and adjust the retractable handle to the height that suits you best, and you can easily stand and clean corners. Equip brush heads with different purposes according to daily life scenarios, such as pointed brushes for cleaning bathroom corners, and sponge brush heads for cleaning surface stains on tableware, glass, and furniture. Different brush heads can be switched to meet different cleaning needs. The design is simple and adopts a button-style installation, which is fast to install. After adjusting the telescopic rod counterclockwise to the desired length, the current length can be fixed clockwise. The design of the handle on the body conforms to ergonomic principles, which can reduce discomfort in the hands after long-term cleaning. It is equipped with a rechargeable large capacity 2000mAh battery for fast charging and wireless use, avoiding the problem of long and tangled charging cables. Efficient and concise product design, suitable as a gift for friends or family who need to decorate their house or prepare for a party, can help them quickly solve cleaning problems.
