Product Description

The Dolphin Diagnostic Advantage

The Dolphin Pool Cleaner is the world's first and best selling robotic pool cleaner.  And after 25 years of scrubbing pools clean, it still leads the industry with its advanced electronics, rugged construction, superior cleaning performance, and unequalled service record.  The Dolphin pool cleaner scrubs and vacuums the pool floor, walls and waterline and microfilters the pool water - it's like adding another filter to your pool!  The Dolphin's reusable filter bag is designed with the optimum porosity to catch the smallest debris yet avoid clogging. It operates with it's own pump and filter system which avoids the wear and tear on your pool pump and filter caused by water-powered cleaners. In fact, the Dolphin Diagnostic Pool Cleaner saves you up to 50% on electricity and backwashing costs and up to 30% on chemical costs!  The Dolphin's water-cooled motors (no oil to leak) are guaranteed for 24 months.  Its extra long 50 ft. self-floating cord is attached to a weatherproof 24 volt transformer which is ETL listed for outdoor use. No installation is required – just plug it in.  It even has a built-in 6 hour auto shutoff and advanced, self-diagnostic software.

Does the unit come with the caddy and the PVC brush for in-ground plaster/masonite/concrete pools?

A  Answered on 6/4/2006 by InyoPools Product Specialist Patrick P.

The NE250 (DL2019) does include the brush.  The caddy is sold separately and can be seen on our web site at Dolphin Caddy

Does the NE250 work with aboveground pools?

A  Answered on 6/23/2006 by InyoPools Product Specialist Patrick P.

No, it does not. For aboveground pools, we recommend the Robo-kleen aboveground pool cleaner. To view it click on this link:

I've had a Polaris cleaner for 15 years and need to replace it. How does it compare to the NE250? Can I use the same booster motor?

A  Answered on 7/7/2006 by InyoPools Product Specialist Patrick P.

The NE250 is a robotic cleaner. It's a little different than the Polaris, but is one of the more popular cleaners on the market. It does not require a booster pump, but rather sucks everything into its own internal filter bag. The bag needs to be emptied periodically, similar to a household vacuum. The Dolphin cleaner will also climb up the sides of your pool unlike the Polaris pressure pool cleaner. We recommend the Dolphin over the older Polaris models.

Our pool is a group of three overlapping or intersecting rectangles. There are inside corners with 90 degree turns as well as outside corners with 270 degree turns. Will the Dolphin Diagnostic, NE250 navigate the outside 270 degree turns?

A  Answered on 7/10/2006 by InyoPools Product Specialist Patrick P.

The swimming pool does not have to be rectangular or round.  It can be any shape and the Dolphin will navigate around the swimming pool. It may favor some parts of your pool, but should clean around the entire swimming pool.
