How do you pick an auto swimming pool cleaner for your pool?
I've been researching but haven't bought one yet...seems the differences are: some attach to your skimmer and run through the pump, others have their own bag & motor. Some clean the walls and the floors, some won't climb (my pool goes from 3' to 10') and work only in a above ground pool. It's certainly worth the research before you buy but from what I hear, WELL worth the money and it's usually recouped because you use less chemicals.
Research the Polaris cleaners first. They are the best on the market. Their website is www.polarispools.com. They will also help you locate a reputable dealer in your area and help you determine which type of cleaner is best for your pool. However, it will not reduce the amount of chemical usage. Having a pool cleaner will save you time in manual cleaning, but will not help sanitize your water. You would need an automated chlorinating system to help with chemical reduction.
I would go with a polaris and from there you have two choices Gunite or vinyl/fiberglass.
I had used a Polaris 360 with its own return line for the last 7 years and it had served me well. Every year I would bring it in for a tune up and it worked very well. This year I decided to retire it and purchase a Dolphin Dynamic electric with remote. I must tell you that I am so pleased and happy. The thing works great and does not tax your filter system. It cost about $1000.00 but you can get one for about $700.00 if you do not want the remote. I like the idea of spot cleaning and directing it to the area with the joystick. The reusable bag is 4 times as large as the polaris and the cleaner does and amazing job. If you are going to spend $700 to $800 on a Polaris and booster pump, I would go for the electric one.
Answ:: I would consider the suction side cleaners to be superior but each cleaner works differently from one pool to the next. Suction side cleaners require no booster pump thus no extra electrical hook ups or have no additional increase in your electric bills with a second pump motor running. And one advantage with the suction side cleaner is that with it installed you now have a movable main drain. Every cleaner has it's limitations. For instance, all are only as good as the capacity of the bag, basket, container or cannister in which the debris flow. Most will not clean the steps, love seats, shelves or spa. Some make clicking noises which a few people object to. ~ only a minor thing. Most "pressure" side cleaners ~ those that work with a booster pump ~ will not pick up very fine dust but will move it around and sometimes get it close to the main drain. Most auto cleaners will not eliminate the need to add chemicals or the need to clean your pool periodically. It also does not mean that you can fire your pool tech either ~ however, you will have a pool cleaner doing the pool every day. The cleaners that have attempted distributing chemicals ( tabs) from the base of the cleaner seem to have failed ~ with the chemicals being too harsh on the cleaner head and parts. k.
I would think if you had health risks they would be throughout the pool water in suspension not on the surface. Also, none of the cleaners on the market have successfully administered chemicals from their units no matter what type of cleaner. One major factor for suction side cleaners ~ those that use a second or "booster pump" is that you are using more electricity to clean your pool and with the emphasis on conservation I would certainly think the less electricity you use the better on your wallet and our environment.
The Area of greatest micro biological hazard to bathers is the top 300mm of any swimming pool. Sunlight, the heat from sunlight and environmental pollutants reduce the biocidal effectiveness of the pools disinfection system, while bathers activities add to the potential risk. Keeping this in mind the best pool cleaning absolution would be to concentrate on the top of the water with an effective floating suction-side pool skimmer, this would remove the majority of contaminant from the surface of the water then redistribute it into the deeper areas of the pool where disinfection stronger and water cooler. An added advantage with this method is that by effectively skimming materials from the surface there will be a reduction in bio-material throughout the water making available more free chlorine which in turn is more economical.

Another factor to consider if you have a printed vinyl liner pool is wear-and-tear on the printed pattern. I've worked in the industry for decades and the repetitive paths and tread stress of some auto cleaners will wear the pattern out prematurely leaving bare spots on your liner. The 'Kreepy Krauly' cleaner is a good choice as it has been the only one I know of to not be a repeat offender. And I don't work for or know any of the K-K people. I work for a vinyl manufacturor and have dealt with these issues over many years of testing/complaints/R&D. Good luck. ~PickGuru
