My oh my where do I begin? I’ll try not to give my age away here but, I remember when Kreepy Krauly’s were one of the first automatic pool cleaners on the market. Infact in 1974 the very first models were actually made of wood and rubber tubing. People lucky enough to have had one of those Pinochio Bot’s absolutley loved them. I’ve heard stories from folk’s (my grandfather of course) who desperately tried to keep them operational by using coat hangers, duct tape and glue. Kreepy Krauly’s were actually sold door to door at one time. Their salespeople were quite clever in the presentation or should I say demonstration. Get the facts about swimming pool cleaners
Knock!, Knock!, Who’s there?, Kreepy Krauly!, Creepy What!. You open the door to see a young salesperson, well dressed in suit and tie jumping right into a full blown introduction of who he is and how he would like to show you an amazing new contraption that promises to bring back joy to owning and caring for your pool. Imagine trying to pull that one off in today’s world, not a chance of you allowing a door to door sale’s person in your home with something creepy they want to stick in your pool. Well anyway, grandpa says sure young fella come on in and show me what the heck you’re talking about.
That young person walks through the house carrying a spiffy looking box in which he follows you out to the pool. Grandpa cannot recall exactly what he said verbatim but it pretty much went like this. ” Sir what we have is the latest and greatest thing ever made for swimming pools” while telling you all the tech stuff he is carefully and deliberately unpacking what clearly is a never opened before package. You watch intently as he pulls this thing out of the box that looks like a cross from an octopus, squid and dive gear all rolled into one. “Sure looks creepy, grampa says”. ” Yes sir we call it a Kreepy Krauly” as he throws it into your pool with what looks like a long umbilical cord attached. Just a few seconds later as this thing sinks to the bottom of your pool and starts pulsating and making a knocking noise like nothing you’ve never heard before and low and behold it starts to move! It’s ALIVE!
Not only is it moving but you can actual see a clean path it’s creating as it knocks around your pool in a direction that appears to be backward from what you would expect. Little Johnny salesman sees the look on your face and quietly says to himself SOLD!. After a short discussion about price and I do mean short because you absolutely have to have it. He politely asks “Sir shall I leave this one in you pool or if you prefer I can get you another from my car” Not necessary you say after all, you know it to be a brand new one as you watched him unpack it right in front of your very eye’s. No way do you want him to take it out of your pool to switch with another because you can’t and don’t want to take your eye’s off of this thing.
By 1978 a sufficient number of units had been sold to cover the cost of plastic injection molding and a legend was born!
Here are three main type’s of pool cleaners each classified by the drive mechanism used in each respective cleaner:
Return Water Flow Back to Pool: Water flowing back to the pool via the pool return lines or a dedicated pool line for the sole purpose of attaching a cleaner that utilizes a drive mechanism that operates on a Venturi principle. (See Venturi in Glossary of Terms) The Venturi not only drives the pool cleaner but also creates a vacuum to capture debris. This type of cleaner usually sends the vacuumed debris right to the pool filter.
Pressure Driven Water Flow Back to Pool: Water flowing back to the pool through a dedicated plumbing line is pressurized by using a secondary pump (booster pump) which enhances the Venturi effect thus allowing the cleaner to move faster and collect more debris in a shorter period of time. This type of cleaner usually has it’s own collection bag, net or screen. Thus allowing longer run cycles between cleaning of the collection vessel and the pool’s main filter.
Suction Side Driven: Water being drawn from the pool from either the pool’s skimmer or a dedicated plumbing line connected to the suction side of the pool’s recirculating pump. The cleaner is driven by a mechanism that is powered by the water drawn through the cleaner and sucking up debris at the same time.
