There is much more to owning a pool than simply outfitting it with inflatable floats and toys, and splashing around in the water for fun. Maintenance is required, and that includes the best suited pool vacuum. While handheld pool cleaners, like nets and skimmers, are great for removing daily debris, robotic pool vacuums are essential when it comes to deep cleaning, but how do you choose the best one for the job? According to the experts we asked at Leslie's Pool, there are three types of vacuums designed for cleaning pools: the suction side pool cleaner, pressure side pool cleaner, and robotic pool cleaner.

Suction cleaners work with the dedicated suction line in your pool or connect to your pool's skimmer; they use the filter pump's suction to propel the cleaner through the pool, vacuuming and cleaning the pool surface to eliminate dirt and debris. Pressure cleaners don't use your pool's filtration system to filter out dirt and debris; instead, they use a filtration bag, which relieves pressure and wears on your filtration system. And if your pool is heated, pressure cleaners help distribute the heat. Robotic pool cleaners are perhaps, more costly than other models, but they have high energy efficiency, reduce maintenance, and rely on your home's power, not your existing pool equipment.

When it comes to choosing the best pool cleaner for your setup, consider your pool's size and design, either as an above-ground pool or in-ground pool.

Top Picks

No matter which type of pool vacuum cleaner you opt to purchase, keep safety in mind before powering on any piece of equipment. The experts at Leslie's Pool suggest to start by vacuuming the bottom part of your pool with an automatic pool cleaner to remove fine dirt and dust particles, working from the shallow end toward the deep end. To help keep your drains and filters clear, they recommend vacuuming waste directly. When the cleaning job is completed, brush the pool surfaces and remove any dirt on pool walls, run the vacuum again. Repeat this process until the pool is sparkling clean.
