Ask in any pool forum which robot to buy and someone will say Dolphin within two replies. Maytronics has owned this category for a long time, and the recommendation is not wrong. But Dolphin's pricing was set when there was no serious competition underneath it, and there is now.
WYBOT is the most visible of the brands that changed that. The comparison is genuinely interesting, because the two brands are not really competing on the same terms.
The short version
Buy Dolphin if you have a large or complex pool, you want the longest service life available, and you would rather pay once than twice.
Buy WYBOT if you have a standard residential pool, you value cordless convenience, and you would rather spend the difference on something other than a pool robot.
Price
This is the whole conversation, so let us not be coy about it.
Premium robotic pool cleaners routinely run past a thousand dollars, and the higher Dolphin models go considerably beyond that. WYBOT's mid-range C1 sits around $450.
That is not a small gap that gets rationalised away by features. It is a different purchasing decision. At $450 a pool robot is an appliance. At $1,400 it is an investment you research for a month.
Cordless versus corded
Most Dolphin models are corded. They plug into a power supply at the poolside and trail a floating cable. WYBOT's range is cordless, running on internal batteries.
Each approach has a real advantage.
Corded means unlimited runtime. The robot runs as long as you want it to, and for a large pool that matters, because a single cleaning cycle might need more time than a battery provides.
Cordless means no cable to tangle, no cable to untwist, and no power supply to position. Anyone who has spent ten minutes unwinding a swivel cable understands why this feature sells.
For a standard residential pool where a 60 to 120 minute cycle covers the job, cordless wins on convenience. For a large pool, the battery becomes the constraint.
Cleaning performance
Here the gap is narrower than the price suggests.
WYBOT's models handle floors, walls and waterline, with filtration rates on the mid-range models reaching 2,642 gallons per hour and brush designs that grip across cement, vinyl, tile and fibreglass. Owner reports describe single cycles clearing leaves, sticks and sand effectively.
Dolphin's advantage is in navigation sophistication and consistency across difficult pool shapes, plus generally better handling of heavy debris loads. On an ordinary rectangular pool with ordinary debris, the difference is smaller than three times the price implies.
Where Dolphin pulls clearly ahead: large pools, complex geometries, and heavy seasonal debris.
Durability and support
This is where premium pricing earns its keep, and it is the argument most worth taking seriously.
Dolphin has a long track record, an established service network, and models that owners report running for many seasons. Parts are available. Repairs are a known process.
WYBOT's budget models carry a one-year warranty. That is not unreasonable at the price, but it tells you the expected relationship. If a WYBOT fails in year four, you are likely buying another one. If it runs for five years, you have spent a third of what a Dolphin costs.
Do the arithmetic honestly. Two WYBOT units over eight years still costs less than one premium Dolphin. Whether that is the right trade depends on how much you dislike replacing things.
The app question
WYBOT's app draws genuinely mixed feedback. Some models require it for configuration, and when it misbehaves, the experience is bad enough that people return working hardware over it. Some WYBOT models need no app at all, which several owners specifically praise.
Dolphin's app-enabled models are generally more settled, though not every Dolphin needs an app either.
If this worries you, it is an argument for buying a model from either brand that works without one.
So which?
Standard residential pool, under about 800 square feet, ordinary debris: WYBOT. The performance gap does not justify the price gap at this size, and cordless is genuinely nicer to live with.
Large pool, awkward shape, or heavy leaf fall: Dolphin. Unlimited runtime and better navigation earn their money here.
You keep things until they break and hate replacing appliances: Dolphin.
You would rather spend $450 now and reassess in four years: WYBOT.
Before you buy either
Measure your pool's surface area and compare it against the model's stated maximum. Check whether the model needs an app and whether you mind. And check the warranty length, which varies more than you would expect within both brands.
Pool equipment discounts hard out of season. Before you commit, check WYBOT's current codes on Discountsmaniac — on a purchase like this, catching a live offer can close a meaningful part of the gap between the two brands.
