Because of the individual characteristics of your pool, some additional adjustments may be required to get the best performance from your Kreepy Krauly.

If there seems to be a problem, check these common causes of cleaner problems. If you still need help, call your pool professional.

• Is bottom main drain closed? Close drainIs filter clean? Clean filterIs pump strainer basket clean? Clean basketIs debris blocking the bottom of the cleaner? Remove debrisAre there any leaks in the hose? Replace leaky section
• Is automatic regulator valve free of debris? Clean valve

If Kreepy Krauly is not moving or not pulsating.

• Check to ensure that the main drain and all suction lines are closed, except for the suction line to which Kreepy Krauly is attached.
• Check for debris in the filter or pump basket.
• Check for debris in Kreepy Krauly’s flapper. Debris may prevent flapper movement or restrict flow.
• Pool pump and filter system may be too small (incapable of providing 14 gallons per minute water flow). Consult your pool professional.

If Kreepy Krauly stays in one end of the pool.

• Check the return line water flow and re-direct as necessary with an eyeball diverter.
• Check that hose is long enough to reach to end of pool.
• Check that Kreepy Krauly has proper hose balance.

If Kreepy Krauly stays on the main drain.

• Check to ensure that main drain is closed. A pool professional may need to assist you.
• Check to ensure that a main drain grate is installed.
• If main drain is not flush with the pool floor, consult your pool professional.

If Kreepy Krauly slows or stops and air bubbles enter the pool at the return line.
Find and correct the air leak that is causing the pump to lose its prime:

• Check the hose to ensure there are no leaks.
• Check the vacuum connection. It should be submerged so no air enters the system.
• Check the pump basket lid for looseness, cracks, and worn or missing o-rings. If you need assistance, contact your pool professional

If Kreepy Krauly is moving too fast.
In most pools, the automatic regulator valve supplies Kreepy Krauly with the proper amount of water flow. However, if used with an especially powerful pool pump, the valve can be overpowered.

• To slow Kreepy Krauly down, a manual bypass valve (Part # 12-094) accessory is available for purchase from your Kreepy Krauly dealer. This manual bypass can be adjusted to achieve the recommended cleaner speed of 8 to 12 feet per minute. NOTE: The manual bypass cannot be used with a vacuum line installation.To decrease the speed of Kreepy Krauly, simply remove the in-line valve cone from the bottom of the automatic regulator valve and replace it with the manual bypass.Press the automatic regulator valve into the threaded compression adapter (or 2 inch hose cone if used). The end of the valve that is marked attach hose this end must point up.Place Kreepy Krauly into the pool and allow it to sink to the floor. Continue to feed the hose down vertically into the pool until it is completely filled with water and purged of air.Insert the hose through the skimmer opening and push it onto the automatic regulator valve.

  Slide the hose protector into position on the hose to prevent the hose body from rubbing against the skimmer opening.

• Adjust the manual bypass while the Kreepy Krauly is running. Place your hand into the skimmer and turn the bypass adjuster one click at a time until the desired speed of 8 – 12 feet per minute is reached.

If Kreepy Krauly pulls air from, or remains at, the water surface.

• Check to ensure the dive float mechanism is operating freely and the dive float restrictor is installed.
• Check the automatic regulator valve for its proper installation and ensure it is not clogged with debris.
• Make sure the water level is at least 3 inches below the pool deck.
• Check to ensure your Kreepy Krauly is operating at the proper speed of between 8 and 12 feet per minute.
  If Kreepy Krauly stays at the shallow end steps.

• Check to ensure your Kreepy Krauly is operating at the proper speed of between 8 and 12 feet per minute.Check to ensure the dive float mechanism is operating freely and the dive float restrictor is installed.
• Shorten the roller bumper strap by 1/2 inch. (Pull out upper end of bumper strap from locking end clip attached to swivel head. Cut 1/2 inch off, then return bumper strap into locking end clip.)

If Kreepy Krauly tracks in a repetitive pattern.

• Check the swivel on the top of Kreepy Krauly. It should turn freely.Check the return line water flow and re-direct as necessary with an eyeball diverter..Check Kreepy Krauly’s hose to ensure it has not become bent or kinked. It only takes one bent or kinked hose section to hinder the cleaning coverage. One way to check for kinks in your hose is to lay each section flat on your pool’s deck (or other flat surface).
• The hose should be perfectly straight and flat. Do not coil the hose when taking your Kreepy Krauly out of the pool because it will retain the coil shape, forming a bend or kink.

If Kreepy Krauly gets stuck on pool obstructions such as a safety ledge, ladders, steps, swim-outs, benches, etc.

• Remove dive float restrictor and install a wall climb adjuster (Part # 12-065). Snap the wall climb adjuster into place. This will keep Kreepy Krauly on the pool’s floor and away from pool obstructions. Make sure the narrow end of the wall climb adjuster points down to the drive tubes. (This accessory is available for purchase from your Kreepy Krauly dealer).
• If Kreepy Krauly gets stuck under your pool ladder, install a Ladder Guard (Part # 12-330) according to the instructions contained in the packaging. (This accessory is available for purchase from your Kreepy Krauly dealer.)

If Kreepy Krauly is still hampered by the unique characteristics of your pool, regardless of the adjustments we’ve provided:

• Consider “Thruster”, (Part # 3-370) the Kreepy Krauly accessory that aids random pattern coverage by automatically repositioning the hose to help free the cleaner from obstacles. Thruster keeps Kreepy Krauly out of tight spots in difficult-to-clean or uniquely-shaped pools. Ask your Kreepy Krauly dealer about this accessory.

TO REMOVE DEBRIS FROM THE FLAPPER

Sometimes debris may clog the bottom of the cleaner and prevent flapper movement or restrict flow. The flapper is located inside the main body and must move freely at all times.You can see the flapper through the opening in the baffle plate, when you turn the cleaner upside down. Jiggle the flapper with your finger or flush the cavity with a hose to force out any debris lodged inside the main body.If debris is still lodged inside, you must remove the flapper. First, lift the lip of the foot pad and insert a flat-head screwdriver along side one of the two tabs found on the baffle plate. Push the tab inward with the screwdriver until the baffle plate releases. Place a finger into the center opening of the baffle plate and pull up until it pops out. Then pull the flapper out. NOTE: Your should be able to do this without taking the footpad off.Once the debris is dislodges, insert the flapper back into position. Be sure that it is securely in place.

The automatic pool cleaner is a device that leapt right into the hearts of pool owners and service technicians alike. In a genesis similar to that of human air flight, engineers and inventors have produced gadgets of fancy in the hopes of finding one that will fly. Several have achieved wide-spread use and acceptance by consumers and the service industry. These are described below and are broken into three categories; suction side cleaners, pressure side cleaners and robots.

These are cleaners that attach to the suction side of your plumbing. The suction side refers to the pipes and fittings that bring water out of the pool to be filtered; that water which is being “sucked” out of the pool by the filter pump. These cleaners include the Hayward PoolVac Ultra, Navigator, Aquabug, Kreepy Krauly, E-Z Vac, Baracuda Ranger, Zippy, Pacer, G3, Polaris 150, and ATV. Please visit our Swimming pool cleaners page for a complete list of suction side cleaners.

These cleaners attach to one of the suction ports at the pool. Usually, this port is the skimmer, or your pool may have a separate vacuum port where the cleaner’s hose can attach. With the hose attached and the filter pump running, suction is created on the underside of the cleaner. The cleaner moves randomly, or automatically around the pool with motion created by a device that gives a stop/ start pulsing of water. As the unit travels, debris is sucked up through the neck and then the hose, past the suction port, through the pipe, and stops at the filter pump strainer basket, while smaller debris passes through to the filter. Adjustments on the hose, the unit itself, and flow volume will create different cleaning patterns, so as to maximize pool coverage.

Cleaner moving slowly?

Start by checking the pump basket for debris and making sure the filter is clean and water is flowing properly. Then I would check out the throat of the cleaner for any obstructions. Obstructions can also be found where the hose attaches to the suction line. Check hose for splits, obstructions or holes. If your pool has lots of leaves (trees), you’ll want to have an in-line leaf trap to use with your suction cleaner.

Cleaner not cleaning the entire pool?

This can be caused by any number of reasons. The hoses could be too short. Another real common cause is the cleaner could be following the flow pattern of the water in the pool, in other words, strong flow from wall return jets will push the cleaner into a pattern. To fix this; adjust the return port wall fittings, or add wall fittings to the return ports. It helps to point the fittings down or at a downward angle. If you pool doesn’t have wall fittings at the return ports there are alternative wall fittings made by the manufactures to divert the flow.

Always rotate the wearable parts on the cleaners and replace those wearable parts when needed. These parts will prevent the need to replace more expensive components. If you have only one skimmer, most skimming action is lost while your cleaner is hooked up. Secondly, unless the cleaner has an in-line strainer basket somewhere on its hose, the filter pump basket can get clogged up rather quickly. That, or if the strainer basket becomes full, reduces filtration and puts more front pressure on the system by restricting the flow into the filter. My opinion is that having a suction side cleaner would be much better than having none at all, but less than what is possible. On the bright side, suction side cleaners are available for half the cost of pressure side cleaners.

These are self contained electric cleaners which are put into the pool when there is a need for cleaning.  Common brand names include Aquabot, Dolphin, and AquaVac. Please visit our swimming pool cleaners page for a complete list of robot cleaners. A transformer is plugged into a wall outlet and a long (around {cord length varies by cleaners} 50 ft ) cord from the unit plugs into the transformer receiving low voltage power to operate the cleaner. This power operates two motors; a pump motor which draws debris into the unit’s filter, and a drive motor which moves the unit around the pool.

The advantage of owning a robot cleaner include their self contained filter, which is easily cleaned. They also do quite well with their coverage. Some units are computer chip controlled and some even have remote controls so you can steer the unit from a lounge chair! Being that they are the only cleaners not attached in any way to the pool’s circulation system, they produce no resistance or back pressure on the filtering. Their cost can be more than suction or pressure side cleaners.

Unit does not move?

Is the indicator light glowing on the transformer? If not, be sure that transformer is turned on and that the 3 volt fuse is not blown (the indicator light can be glowing even though the fuse is blown). Check the electrical outlet with another electrical appliance to be sure that power is available. If the power is available, and the fuse is good try wiggling the power cord plug from the unit to the transformer. Older units may begin to short out at the plug; a new plastic female plug is available. Inspect the unit itself while it’s partially underwater. Is the pump motor receiving power? Is there water gushing out of the top of the unit? This would indicate that power is reaching the unit. Is the pulley on the drive belt side turning? If the pulley is not moving this could indicate a shorted motor or a corroded drive T, which would also require motor replacement. Are the drive belts tight and in good repair? Drive belts become stretched and weaken over time. If your belts are “skipping” and are not locked into the grooves of either the drive pulley or the wheel tubes they may need to be replaced. Check that the wheel tubes are in proper position with bushings in place on either end. If the tubes are not straight the drive belts will not be tight. Do not pull the unit towards the side of the pool, or lift the unit out of the pool by the power cord. Try to reach into the pool and lift the unit only by the handle.

Unit does not pump?

If the unit moves, but does not pick up any debris, lift the unit up near the surface of the water. Does water gush out of the top? If not, the pump motor may be shorted. Unplug the unit and pull it out of the water. Remove the vent cap on top of the unit and check that the impeller does not have string wound around the base. Turn the impeller by hand to check spin. Plug in the unit and check spin. If there is no spin the pump is probably shorted. Another indication that the pump motor is not working properly is if the unit won’t climb the walls very far before falling off. The pump motor provides the suction it needs for climbing.

Pressure Cleaners:  In-Ground Pools

These cleaners are those that attach to the pressure side (return) of your circulation system.  The water that is being pumped or “pushed” back to the pool powers these units which have their own hydraulic power plant inside. Being on the pressure side, these units have distinct advantages. They are helpful in distributing clean filtered water around the pool and having their own debris bag means that they don’t compromise the filter system. Even with the bag full, a pressure cleaner still operates, stirring debris up;  it just won’t suck up any more debris until the bag is emptied.

These cleaners attach to one of the existing return ports and are powered by the pool pump (Polaris 360,  Letro Legend II, Jandy Ray-Vac, etc.), or to a dedicated cleaner line and an additional Booster Pump (Polaris 180, 280, 380 and Letro Legend). For a complete list of swimming pool pressure cleaners, please visit our cleaners page. The water that flows into the unit splits into three directions; the sweeper tail, the thrust jet and the venturi.

The sweeper tail is a little “stirrer-upper” as I call it, which helps to get fine debris off the walls and floor and into the suspension where it can then head towards the filter. The thrust jet is a series of ports and gears which motor the unit around the pool in a random pattern. The venturi is the port where leaves are sucked up into a bag (that you empty when full) as the unit rolls over debris. An in-line back-up valve reverses the flow every few minutes to change its pattern and remove it from possible obstacles.

The Polaris 180, 280, 380, and the Letro Legend require a booster pump to power the unit. These cleaners need about 30 PSI to operate effectively. Most filter systems don’t run that high of pressure to run these cleaners effectively. The return pipe is cut after the filter and feed water is directed to the booster pump which then pumps water through a dedicated line midway down the pool wall. This line can be run under the deck and through the pool wall, or over the deck for a cheaper installation. Without the booster pump, these units would crawl along slowly, picking up very little debris.Polaris  360 model  operates at only 15 – 17 PSI, and thus is not intended for use with a booster pump. Letro followed suit and introduced the LEGEND II. These two cleaners I call “low pressure side cleaners.”  This has given these manufacturers a whole new “market share” by reducing the cost of installing one of their cleaners. The 360 & Letro operate in a very similar fashion to the booster pump cleaners and connects to one of the existing return ports. A test is made at that return port to determine if the circulation system can deliver the proper amount of pressure to operate the unit.

The 360 will not work well for pools with floor returns or “slit” returns of crushed copper pipe, or pools with small, slow circulation systems. The 360 and Legend II can be as effective in cleaning the pool as the booster pump driven models. The big advantage to the booster pump models is that they are usually run with a time-clock, and can thus turn themselves on and off automatically.

Lo Pressure pool cleaners such as the Polaris 360 or the Letro Legend II operate at a lower pressure (17 – 19 psi) than does the Polaris 180 or Polaris 380, which require pressure above 30 lbs to work effectively. This is why the 180/ 380 require an additional booster pump to send higher pressure water to the unit. And of course, the booster pump requires hard-wired electric on it’s own circuit breaker, with its own timer clock as well as plumbing and trenching from the booster pump to the unit. The last four feet of this run can go under the pool deck and through the wall for best results, or the installer can use an over the deck mounting kit.

The Booster pump driven cleaners do have 3 main advantages over the 360. One, since it has its own booster pump, the speed and efficiency of the cleaner is not dependent on the filter/pump system. That is, if your filter, pump or skimmers are clogged, the 360 will slow down from lack of flow. Secondly, the 380 usually is installed with its own time clock, so that it turns itself on & off. This can save wear & tear on the unit, and has a convenience advantage, making it truly automatic. Third, the booster pump models are usually a bit faster because of the “boost” and also do not put any back pressure on the system.

Lo Pressure cleaners do not require a booster pump, or plumbing or electricity. The installation requires only to plug it into one of your existing returns on the wall, making adjustments to reduce the flow from other returns to achieve 17 – 19 psi of water flow to the unit. NOTE: A filter pump of at least 1 hp is needed to achieve proper pressure. Small duty pumps such as the MaxFlo, the Maxim, the PowerFlo or other above-ground or small inground pool pumps do not have enough power. A pressure tester is included. It is advised that you properly pressure test the unit before putting the cleaner into the pool.

The Polaris 360 comes with detailed instructions on how to connect it into your particular wall fitting. A G-9 wall adapter is needed if you are connecting it to a 3/4″ threaded wall fitting. The Polaris 360  has 25 feet of feed hose included. If your wall returns are on one end of the pool, you may need additional hose sections for complete pool coverage. The Polaris 360 or Letro Legend II are suitable for vinyl-lined pools and for gunite pools of any shape. A great replacement for the Jandy RayVac pool cleaner.

The water that is being pumped or “pushed” back to the pool powers these units which have their own hydraulic power plant inside. Being on the pressure side, these units have distinct advantages. They are helpful in distributing clean, filtered water around the pool and having their own debris bag means that they don’t compromise the filter system. Even with the bag full, a pressure cleaner still operates, stirring debris up, it just won’t suck up any more debris until the bag is emptied.

These cleaners attach to one of the existing return ports, or to a dedicated cleaner line. If you currently have a dedicated ’suction’ pool cleaner line, it can be converted to a ‘pressure’ pool cleaner line.

The water that flows into the unit splits into three directions; the sweeper tail, the thrust jet and the venturi. The sweeper tail is a little stirrer-upper as I call it, which helps to get fine debris off the walls and floor and into the suspension where it can then head towards the filter. The thrust jet is a series of ports and gears which motor the unit around the pool in a random pattern. The venturi is the port where leaves are sucked up into a bag (that you empty when full) as the unit rolls over debris. An internal back-up valve reverses the flow every few minutes to change its pattern and remove it from possible obstacles. And this is how it works!

Lo Pressure pool cleaners work best on a dedicated line, and with a pump and filter that can maintain decent pressure – otherwise, these cleaners can run very s-l-o-w. However, they can be a great, cost effective alternative to the more expensive, energy consuming booster pump driven pool cleaners.

Inspect the unit itself while it’s partially underwater. Is the pump motor receiving power? Is there water gushing out of the top of the unit? This would indicate that power is reaching the unit.

Is the pulley on the drive belt side turning? If the pulley is not moving, this could indicate a shorted motor, or a corroded drive T, which would also require motor replacement.

Are the drive belts tight and in good repair? Drive belts become stretched and weaken over time. If your belts are “skipping” and are not locked into the grooves of either the drive pulley or the wheel tubes, they may need to be replaced. Check that the wheel tubes are in proper position with bushings in place on either end. If the tubes are not straight, the drive belts will not be tight.
