We carry every Dolphin robot by Maytronics. Here are the models built to handle $300 best — with the filtration, brushes, and navigation that matter most at this price.
Dolphin builds one of the widest robotic pool cleaner lineups on the market, so choosing the right one under $300 comes down to matching the robot's filter, brushes, and navigation to the job.
Here's the honest truth: reliable robotic pool cleaners under $300 are rare, and most no-name models at that price disappoint fast — weak suction, tiny baskets, and no wall climbing. The smart move is to get as close to that budget as possible with a robot that will actually last.
Under $300, be skeptical of ultra-cheap robots that skimp on motors and filtration. Your best value near this budget is Dolphin's entry model, the E10, plus current rebates and refurbished deals that bring a quality robot closer to your price. A dependable cleaner that lasts years beats a bargain robot you replace in one season.
These are the Dolphin models we recommend most under $300, ranked for this job. Every one ships free with a 30-day trial.
Dolphin's most affordable robot and the best-value entry point near this budget — simple, reliable floor cleaning.
A compact, capable Dolphin that's often reachable at this budget with rebates or open-box pricing.
Three easy ways to get more robot for your money: Certified refurbished Dolphins are professionally restored and tested, often saving hundreds off a new flagship. Open-box units are returns in like-new condition at a discount. And current Maytronics rebates can knock the price of a higher-tier robot down into your budget. Every one of these still ships free with our 30-day trial and no restocking fees.

Quality options under $300 are limited — most cheap robots underperform. The best value near that budget is Dolphin's E10, and refurbished or rebate deals can bring a quality robot closer to your price.
Usually not. Bargain robots often have weak suction and no wall climbing, and they fail quickly. A reliable entry model like the E10 costs a bit more but lasts far longer.
Look at certified refurbished and open-box Dolphins, and check current Maytronics rebates — together they can drop a better robot into your budget.
