10 Best Robotic Pool Cleaners: Your Easy Buying Guide (2018)


best robot pool cleaner


Built-up dirt, algae, debris, and grime can quickly made your pool look dirty and uninviting. A robotic pool cleaner can save you a tremendous amount of time and energy, giving you more time to relax and enjoy swimming in clear, refreshing water. Robotic pool cleaners aren’t a cheap investment, but you also don’t have to go over your budget to find a decent cleaner that will get the job done right.

The type of pool you own, desired features and budget will make it easier to narrow down possible options. For example, if you own a larger in-ground pool that accumulates a fair amount of debris, you may want to invest in a bigger and more powerful cleaner that can keep up with falling leaves and other debris. On the other hand, a smaller and less powerful cleaner might be all you need to adequately maintain a smaller pool.

Your budget and the type of pool you own are some of the biggest factors to consider. However, you’ll also want to keep in mind which robotic pool cleaner will be best for the specific needs of your pool. For example, if scum tends to build up along the water line, you might want to invest in a vacuum that is specifically designed to sweep away build-up in that area. Some vacuums are better at climbing stairs, while others maximize performance and efficiency to get the job done faster. As these vacuums can get quite heavy when full, you may want to look for one that lets you drain out the water. Some also come with a carrying caddy for easier portability.

1. Best In-Ground Pool Cleaner: Dolphin Premier

The Dolphin Premier is considered the flagship Dolphin pool cleaner, and for good reason. Dolphin has a solid reputation among pool owners for its dependable products, and this Dolphin pool cleaner doesn’t disappoint. In addition to its reliability, the Premier comes with a number of products to make pool cleaning and maintenance less stressful. For example, it comes with four distinct media filters to make sure the job is done right. You can choose the micro-cartridges for cleaning algae and other fine particles, then swamp it out for the large debris bag when cleaning out leaves.

Aggressive rubber tracks help secure the vacuum to the side of the pool for effective cleaning. Innovative navigation software helps guide the vacuum in a methodical pattern, while sensors keep it from getting stuck on obstacles such as drains and pool ladders. Other highlights include 360 degree swivel cords to avoid tangles, dual scrubbing brushes and efficient motors that use less energy without sacrificing performance.
