Off-Season Dolphin Storage & Pool Closing

Bonus! (20+) Tips for Maytronics Dolphin Users

The Dolphin Difference

Jeff Yeager, for AARP, says taking “a few hours this Fall to button up your house and other valuables for the Winter can save you big bucks” later. Protecting possessions from harsh weather conditions, he notes, can be easy and inexpensive to do. Safeguard your patio and plants against rock salt spill. Disconnect that gas grill’s propane tank and store it along with attendant flexible tubing—which is prone to cracking—in a shed, garage or basement.

“The Cheapskate Next Door” and “Don’t Throw That Away!” author is onto something. If your outdoor faucets aren’t designed for use all year long or properly insulated, he adds, shut off their water supplies. Then open and drain those fixtures long before temperatures drop to, or below, freezing. Same goes for below-ground irrigation or pool area landscaping systems. But what about your pool and your pool cleaning robot? What’s to be done about those?

I’m here to tell you—with closing hints and 20+ helpful tips for off-season care.

Dolphin Storage & Pool Closing

Your Dolphin robotic pool cleaner is built to be hard wearing and durable. To keep it that way Maytronics urges you to use your Dolphin pool cleaning robot responsibly. In general, your pool’s pH levels should be maintained at a range of 7.0-7.8. Chlorine levels should reach 4 ppm max. Adequate salt, or NaCl, levels are 5000 ppm. Ideal pool temperature is 43-93 deg. F. (For those using, or fond of, the metric system that’d be 6-34 deg. C.)

When your pool and automatic pool cleaner are not in use, such as off-season or when you take perhaps a weeks- or months-long Summer vacation (A girl can dream!), Maytronics recommends stowing away that Dolphin robot. If you plan on leaving your unit unused for an extended period of time, there are steps you can take to adequately prep it for storage. This ensures that it’ll be raring to go, when you are—next month, season or year:

•   Disconnect your robot from its power supply.
•   Drain all water from your Dolphin pool cleaner.
•   Remove, clean and reinsert filter bags or cartridges.
•   Roll up your Dolphin’s power cable avoiding any kinks.
•   Store your robotic vacuum upside down under a shelter.
•   Place it, ideally, out of reach of direct sunlight, rain or frost.
•   Avoid storage area temps beyond 41-113 deg. F (5-45 deg. C).

Bonus Tip! For best results store your robot on a sturdy Dolphin-sized caddy and under a covering, as these items offer added protection from the elements. Click HERE for a tutorial on Maytronics Dolphin caddy assembly.

Maytronics knows pool owners like you want to enjoy life more. Worry less with our Dolphin storage tips!

The Assoc. of Pool & Spa Professionals also recommends preparing pools, spas and hot tubs for the off-season or extended downtime. Their tips vary according to which climate you’re in: Mild weather or Severe (aka harsh) weather.

If you live in the Snow Belt—essentially the upper-third of the U.S., dipping down to include Wyoming, Colorado and parts of California—and have an in-ground pool you can get specific pool-closing tips HERE.

•   In Mild climates, maintain normal operation.
•   That includes water level, pH and routine sanitizing.
•   Keep tabs on calcium hardness and total alkalinity levels.
•   Cover pools and spas when not in use to keep debris at bay.
•   Continue circulating unheated water through the entire system.
•   Consider investing in timers, like those on remote control Dolphins.

Bonus Tip! Use Dolphin robotic vacuums with multi-layer filter systems to safely capture and easily dispose of large, fine and ultrafine debris which can otherwise compromise your pool system.

Who couldn’t use a little extra insight here and there? We’ll round out this piece with a few helpful hints and tips that’ll come in handy any time of year.

They can be of tremendous value when you’re using your Dolphin on a day-to-day or frequent basis. Again, I urge you to refer to your unit’s own User Manual for specific instructions, as they may vary from model to model:

  • Begin by connecting the unit to a power supply.
  • Your power supply should be positioned in the shade.
  • NEVER power your Dolphin cable via an extension cord.
  • Power supplies should be 10+ ft. (3+ m) from the pool’s edge.
  • Rinse wonder brushes well, if so equipped, under running water.
  • Store your robot in the shade—if not on a caddy, then upside down.
  • Use minimal floating cable length, leaving any excess outside of the pool.
  • After EACH pool cleaning cycle, rinse the unit’s filter bag or cartridge clean.
  • After EACH cycle, take your Dolphin out of the water to preserve plastic parts.
  • Soak combined or wonder brushes with water, if so equipped, prior to operation.
  • Unplug weekly, untangling the cable and letting it lay flat in the sun for a few hours.
