The Maytronics Dolphin Nautilus can clean pools up to 50 feet in length, which is larger than you'll find in the average suburban backyard. It will finish scrubbing, vacuuming and filtering all the surfaces the average pool has to offer in about three hours, using an amount of electricity that Maytronics estimates will cost you 15 cents. So for the price of this mid-range pool-cleaning bot you'll get one heck of a lot cheaper work than you'll find from the guy who does your next door neighbor's pool. All that it takes to use it is to plug it in, pick it up and drop it in the water. It will then begin crawling back and forth on the floor and walls of your pool, turning on a special swivel unit in the power cable that prevents it from becoming tangled.
You may or may not see it as a feature that there's no way to program that Nautilus. It comes with its programming built-in, with no parameters for the user to set. It scans the pool, figures out the most efficient course that will take it along all the surfaces, and starts cleaning. It's lightweight, which you'll appreciate when you carry it out from the garage to put it in the water (though you'll probably appreciate it even more when you reach in to pull it back out, pausing to let all the water drain out before stowing it back in whatever nook you keep it in). The filter is in a spring-loaded cartridge that comes popping out when you ask it to, so you can hose it down and dump the larger contents, like leaves, into the trash.
Maytronics' closest competitor in the affordable end of the automated pool-cleaner market is probably Aquabot, so check out the Aquabot Supreme and the Aquabot Pool Rover S2-50. But also look at some of the other offerings on Amazon and Home Depot, like the Hayward AquaVac 500 and the Smartpool 4i.
Lasted 2 seasons, bad motor that would have cost $460 to repair. That price did not include a set of bearings that were going bad. Epic fail.
Works great. Cleans great. Easy to maneuver around the pool Gets even the smallest particles out of the pool with each cleaning.
Big leaves might get stuck in the vacuum intakes and prevent the pool cleaner from working.
The dolphin nautilus is lightweight and easy-to-use, with exceptional performance at an affordable price.
It has its own internal pump system and filter and does not need the pool pump and pool filter to work.
Suction is great, the cord hasn't gotten tangled, and my pool is 99% spotless. I use it everyday and it finishes the job in a little more than 2 hours.
