Ready to mount on your truck or trailer, the Service-21 can cut your cleaning time as much as 50% and that can mean hours off your day. Also available is the Service-30 with the larger head and a longer cord (60').
Standard Service-21 unit includes: Cart, 21" head, 40' floating power cord, truck/trailer mount and two debris bags.
Unit does NOT include battery, battery charger, pole, or chemical jugs. Due to ongoing improvements, products may be different from those pictured.
What kind of battery will you need?
We suggest the use of a 12 volt deep-cycle marine battery and a 10 amp automatic charger. Marine batteries typically come in series sizes 24, 27, and 30. We suggest a series 27 size battery. The bigger the battery, the longer the run-time. Avoid marine starting batteries, as they may have a shorter life span. A general purpose trolling motor battery will work fine. Sealed, or maintenance-free batteries are a good idea so you don't have to check liquid levels.
Your charger should be able to handle 10 amps or better. Most automatic chargers have different settings fo 3 amp, 6 amp or 10-15 amps. For full overnight charging, you should use a 10 amp setting.
