ROTOMITE™

Rotomite is a self-propelled dredge whose maneuverability makes it ideal for cleaning irregularly shaped ponds, lagoons and basins.  Its powerful cutterhead and pump ensure consistently high pumping capacity and impressive performance for pumping heavy concentrations of solids.  While the Rotomite™ is fully self-propelled and moves without the aid of cables,  you may elect to operate it on a traversing system if you so desire. It comes equipped with both self-propulsion and is set up to accept a traverse system as well.  

Models Available:   
Rotomite™ 4000;   Rotomite™ 6000
