What's included?

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 31. 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.

Did you know this?

Did you know that you can replace a motor and cord assembly by yourself with a few hand tools? If you have a motor problem, and you have a spare motor assembly, you can install a new motor assembly by only removing four screws in the vacuum head. You can send your broken motor to us and get back to work in minutes. See MOTOR PARTS AND ASSEMBLIES tab in the parts listing.

The Service-21 and Service-30 are the first choice for pool service technicians from Key West to Alaska.

Our service units are designed for pool to pool service route work. The popular Service-21 is now the industry standard for a self-contained cleaner. Instant cleaning means no set-up times, no pumps to prime, and no valves to set. You'll work faster and easier than ever before.

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').

We go where you go.

mount tilt

Both the Service-21 and the Service-30 include our original tilt-on, tilt-off mount system for truck or trailer. Simply wheel the cart up to the mount, tilt up, latch down the safety clamp and set the safety pin. The unit is safely and securely stored for transport to your next pool, near or far. **PLEASE NOTE: ONCE THE MOUNT ASSEMBLY IS INSERTED INTO THE RECEIVER HITCH YOU WILL NOT BE ABLE TO LOWER YOUR TAILGATE WITHOUT REMOVING THE ASSEMBLY.

With a design like this, we can't steer you wrong.
