I used to have one years ago of a different brand and the suction wasn’t good at all so it put me off purchasing another once it broke. With the absolute struggle of dragging my large vacuum cleaner outside and fiddling around with extension leads I decided I needed to try a specific car vacuum.
It plugs into the car power so very practical and easy to use. Suction is excellent. I’ve found if you keep it clean the filter doesn’t need to be changed often.
