Best Robotic: DOLPHIN Nautilus CC Plus Automatic Robotic Pool Cleaner

Buy On Amazon Buy On Walmart

For a pool cleaner that requires minimal user intervention and has plenty of power and features, check out the Dolphin Nautilus CC Plus. This robotic pool vacuum uses its own power supply to navigate across your tile, fiberglass, cement, or vinyl inground pool. It also will climb the walls of the pool, scrubbing all the way to the waterline. 

With a robotic pool vacuum like the Dolphin Nautilus CC Plus, you can skip the skimmer system. Instead, this pool vacuum contains its own filter media. Rotate between standard duty filters for general debris or fine corrugated filters for smaller particles. The unit is programmed for a 2-hour cleaning cycle and is a good match for pools up to 50 feet in length.

Best for Small Pools: Zodiac Baracuda G3 W03000 Advanced Suction Side Automatic Pool Cleaner

Buy On Amazon Buy On Walmart

This pool cleaner makes quick work of the tedious task of vacuuming your pool floor and walls. The Zodiac Baracuda G3 Automatic Pool Cleaner is a suction side pool cleaner that connects to your pool’s skimmer or to a dedicated suction line. Equipped with a 36-point disc, the Baracuda G3 is designed to glide smoothly across your pool surface without getting stuck on obstacles, like drains or lights. In addition, a wheel fitting behind the head of the cleaner helps to steer the vac clear of tight areas, like behind stairs. 

Whether you have a single, two-speed, or variable-speed pool pump, the Baracuda G3 is a good choice. It’s designed to work with even low-speed pumps and it’s equipped with a FlowKeeper valve to regulate the speed of water flow. Whether you have a vinyl, tile, concrete, or fiberglass pool, this automatic pool cleaner is ready to take on your dirt and debris. 

Best Suction: Zodiac MX6 Suction Automatic Pool Vacuum

Buy On Amazon Buy On Walmart

Suction pool cleaners are an efficient, easy way to keep your pool clear of algae, dirt, dust, and debris. By connecting to your pool’s skimmer or dedicated vacuum line, a suction side pool cleaner will automatically traverse the floor and walls of your pool, grabbing up anything in its path. 

The Zodiac MX6 is equipped with 4 belt-driven wheels and a cyclonic suction mechanism to capture small and medium-sized debris. Large debris, like palm fronds, may clog the vacuum—but it’s a cinch to open the center compartment of the vacuum and free the mechanism of any oversized items. An advantage of suction pool cleaners is their ability to climb the walls of your pool, delivering a more thorough clean-up to the waterline. To make it more efficient at wall climbing, this model features an articulating turbine blade.

Best for Above Ground Pools: Hayward W900 Wanda the Whale Above Ground Pool Vacuum

Buy On Amazon Buy On Walmart Buy On Home Depot

Above ground pools sometimes pose special challenges when it comes to keeping the water clean and sparkling. While some inground pools have built-in suction lines to attach a pool vacuum, above ground pools typically rely on manual cleaning. 

If you’re looking for an easier way to maintain your above ground pool, Hayward’s Wanda the Whale is here to help. This above ground pool cleaner connects to your pool’s skimmer system and uses a turbine to pull up water from the bottom of the pool, sending debris up the hose and into your skimmer as it goes. It can handle pools up to 27 feet in size and uses a SmartDrive system to efficiently steer the vacuum and make the most of each cleaning session. Keep in mind that this pool cleaner won’t climb the walls of your above ground pool; it’s strictly for keeping the bottom of the pool clean, which it does well.  

Best for Inground Pools: Hayward W3PVS20JST Poolvergnuegen Pool Cleaner

Buy On Amazon

If you’re searching for an automatic pool vacuum for your inground pool, the Hayward Poolvergnuegen Pool Cleaner is a long-standing popular pick. This 2-wheel drive version is sized right for pools up to 16 x 32 feet, but a 4-wheel drive version is also available for larger in-ground pools. The treads of the tires enable the Pool Cleaner to travel unhindered across the pool floor and up walls, despite encountering lights, drains, or other obstacles. It weighs only 5 pounds, making it easy to transport it to and from the pool in between cleaning sessions.

Other unique features of the Hayward Poolvergnuegen Pool Cleaner include interchangeable throat plates that can be swapped out to maximize suction based on flow rates or to accommodate larger debris. The unit is also programmed with internal steering sequences to vary the Pool Cleaner’s path and ensure more even cleaning coverage. Pair this pool cleaner with at least ½ horsepower pump (or 35 GPM) for a cleaner, clearer pool.

Best for Vinyl Pools: Pentair 360042 Kreepy Krauly Pleated Seal Pool Cleaner

Buy On Amazon

Pentair’s Kreepy Krauly Pleated Seal Pool Cleaner is powerful enough to tackle algae, dirt, and debris, but gentle enough for vinyl pools. The soft, pleated skirt on the head of the Kreepy Krauly isn't overly abrasive on the vinyl liner of your swimming pool when compared to some brushes or wheels of other pool cleaners. It also keeps the design simple with minimal moving parts and no wheels, gears, or diaphragms.

This pool cleaner relies on a dive float system to guide it along the length of your vinyl pool and up the wall to the waterline. Connect it to your pool’s suction line or skimmer, and the Kreepy Krauly will get to work capturing debris that you’d otherwise spend hours vacuuming manually.

Best for Leaves: Polaris Vac-Sweep 360 Pressure Side Pool Cleaner

Buy On Amazon

A pressure pool cleaner hooks up to the return side of your pool pump, using the incoming pressure of clean water to power the vacuum on its cleaning mission. While some models require the use of a separate (and costly) booster pump, the Polaris Vac-Sweep 360 is a standalone unit that simply connects to the pressure line. 

This model is a great choice as a pool cleaner for leaves since it’s equipped with an onboard filter bag that collects larger debris—like pine needles, acorns, pebbles, twigs, and more. The advantage of this system is that collected items are contained for easy disposal, rather than clogging your skimmer or pool filter. The Vac-Sweep 360 features three propulsion jets and an all-wheel-drive system that powers the three wheels for better maneuverability and efficient cleaning.
