Jimmy W7 is a portable wireless upright floor cleaning machine. The innovative design of double roller brushes and two-way counter-rotation eliminates the unbalanced driving force of single rotation direction, making it easier to use. The roller brush's rotating speed is as high as 500 rpm, which can remove stains without leaving any marks and spray the dirty water into the sewage tank in the middle. Multiple nozzles spray water evenly on the brush, precisely controlling the humidity, allowing the ground to dry quickly in 10 seconds without leaving any watermarks. The roller brush can be self-cleaned to avoid making the floor dirty with the stained brushes. The brush can rotate 180° to clean the corners flexibly. The replaceable large-capacity lithium battery pack can last up to 30 minutes.
