Types of Pool Cleaners

Robotic pool cleaners

These are by far the most popular of the best pool vacuums because they do the work for you and use less power. The robotic cleaner will run off of an outlet attached to your house rather than your pool hose, which eliminates strain on your existing pool system. This type of cleaner will also scrub the sides and bottom of the pool in addition to catching debris and dirt from the surface. This means you don’t have to spend extra hours scrubbing the sides of your pool and can go and enjoy a nice pool-side barbecue while the robot does its thing.



  • Cleans the entire pool top to bottom
  • Doesn’t use the pools filtration system
  • Energy efficient
  • More expensive to buy

Pressure Side pool cleaner

The pressure side cleaner uses a separate filtration bag to collect debris and dirt it picks up while cleaning. This means that there is less strain on the filtration system in your pool. This type of cleaner uses a pressure side line to push the cleaner across the pool. In some cases, an additional booster pump is required to give the cleaner enough power to propel.


  • Costs less than other pool cleaners
  • Takes very little effort to maintain
  • Doesn’t use the existing pool filter
  • Will use the pool’s pump to run
  • Extra accessories are sometimes required
  • Suction side pool cleaners

Suction side pool cleaners

The suction side cleaner uses your existing pool filtration system to propel itself across your pool as it cleans. This system will clean the surface of your pool efficiently and costs a lot less than most of the other pool cleaning systems.


  • Lower cost to buy
  • Durable because it has few parts
  • Takes very little effort to maintain
  • Lightweight
  • Will strain existing filtration system
    and pool pump

What To Consider When Looking For The Best Pool Cleaners

Selecting a pool cleaner is a challenging task because of how many factors need to be taken into consideration. The best pool vacuum needs to meet certain criteria before it can be deemed suitable for the majority of pool owners. Some of these criteria considered include;

  • The average size of the in-ground and above ground pool needing a pool cleaning system. Some units will clean up to 60” but if your pool is only around 30” then there is no need to spend the extra on a higher capacity cleaner.
  • The area the pool is situated in. If you live in an area surrounded by oak trees, then having a pool cleaner only capable of skimming the water surface is not very helpful or efficient.
  • Does the design promote independent cleaning with little to no supervision? If the unit is designed in such a way that it gets stuck over every light and bump over the pool’s surface, then you will be spending a lot of time checking on its progress which is not an effective use of your leisure time.
  • Does the price of the unit match the quality of the features? You may think that a unit in the $1000 range should work perfectly and independently, but if the features on that unit don’t match the price tag, then you have wasted your money.
