A self-contained solution tank with the capacity to clean large rooms.
Interchangeable sponge and brush attachments to scrub away embedded dirt and debris.
A squeegee pickup blade for a fast, clean and streak-free finish.
Precise trigger control over the spray application of liquid cleaning solution.
