The I24BTL+ is a self-propelled unit designed specifically for professionals like cleaning contractors. We know a busy schedule can mean that doing a job with speed is often as important as doing it well. That’s why the I24BT has an oversized tank capacity of 15gal, up to 99lb of pad pressure, and parts made of die-cast aluminum and steel. This machine is durable, efficient, and easy to transport. Equipped with a lithium ion battery, makes battery maintenance and down time a thing of the past.
