Today’s Tiger Shark
Pool Cleaner is remarkably similar to the Dolphin Diagnostic. They both have
direct drive; a gear wheel that directly engages the tread, and a sealed
compartment that contains both water pump and drive motor. Similar shaped bodies and handles.
Many Parts are interchangeable with the Dolphin
Diagnostic. Many bushings, the bottom plate, tread, Power cables and wheels appear to be interchangeable. I believe the power supply too. The only part that didn't measure up was the direct drive sprocket.
The Aquavac robot line was purchased by Hayward Pool Products around 2008-2009. Seems Hayward contracts with Maytronics to build these machines. That is an educated guess.
A close friend whose Aqua Queen I autopsied for this report, loved that robot. It worked flawlessly for at least 10 years until disabled by a lightning strike.
The Tiger Shark comes equipped with 55 feet of cable and operates on 24 volts D/C. The filter is a reusable cartridge that filters down to 5 microns. Space for debris holding seems relatively limited and the cartridge rack takes up much more space than the bag.
I am a huge fan of using disposable bags in robots for the convenience and cleaner hands.
If you wish to use a bag, reuseable or disposable, then a new or used bottom plate from a Dolphin Diagnostic or a bagged Tiger Shark model may be used. I have never cleaned a cartridge but it looks like a messy job.
There are distinct differences between newer Tiger Shark
parts and older Aquavac parts. Most significant is the Hayward power
transformer supplys DC voltage and the Aquavac supplies AC voltage. These transformers must only be used with the proper machine
Pools and Spas, Inc, is now a dealer of both parts and robots and is now an authorized repair facility for Dolphin
and Tiger Shark. Without their help this section would be impossible to write.
