Polaris 360 Wont Stay On Bottom Of Pool

Okay, picture this: it's a Saturday afternoon, the sun is blazing, and all you want is a refreshing dip in your pool. You’ve been looking forward to this all week! But then you notice something… off. Your trusty Polaris 360, affectionately nicknamed “Pooly McCleanface” (don't judge, we all name our pool cleaners!), is just kinda... floating. Like a derelict spaceship adrift in the vast expanse of your pool. Not exactly what you paid for, right?

That's precisely the problem we're tackling today. Your Polaris 360 isn't staying on the bottom of the pool. It's a common issue, trust me, you're not alone. And thankfully, it’s usually fixable with a bit of detective work. We're going to dive deep (pun intended!) into the possible causes and offer some solutions to get Pooly McCleanface back to doing what he does best – scrubbing your pool floor.

Why is My Polaris 360 Floating? The Usual Suspects

Alright, let's put on our Sherlock Holmes hats and investigate. Several factors can contribute to a Polaris 360 refusing to stay grounded. We’ll break them down into manageable chunks.

Insufficient Water Pressure

This is the big one, the prime suspect in most cases. The Polaris 360 relies on water pressure to create suction, which keeps it plastered to the pool floor. If the pressure is too low, it simply won't have enough grip. Think of it like trying to climb a wall with only a gentle breeze pushing you – not gonna happen.

How do you know if this is the issue? Well, watch your Polaris in action (or lack thereof). Does it seem to be moving sluggishly? Are the wheels barely turning? Is the sweep hose (the tail) listless and unenthusiastic? These are all signs of low water pressure.

Troubleshooting low water pressure:

• Check your pump: Is it running at the correct speed? If you have a variable-speed pump, make sure it's set to a high enough setting for the Polaris to operate effectively. Some pumps have a dedicated cleaner setting – use it! (Pro tip: read your pump’s manual!)
• Inspect your filter: A clogged filter is a major pressure killer. Backwash your filter (if you have a DE or sand filter) or clean your cartridge filter thoroughly. Trust me, you'd be surprised how much gunk can accumulate in there. (Side note: regular filter maintenance is key to a happy pool and a happy pool cleaner!)
• Look for leaks: Even a small leak in your plumbing can significantly reduce water pressure. Inspect all your pipes, fittings, and connections for any signs of leaks. Look for drips, damp spots, or even just a slight increase in your water bill.
• Examine the Polaris dedicated line: If your Polaris is connected to a dedicated cleaner line, make sure the valve is fully open. Sometimes these valves can get partially closed, restricting water flow.
• Check the inline strainer: Most Polaris 360s have a small strainer basket built into the inlet swivel. This strainer can get clogged with debris, reducing water flow. Clean it regularly! (Hint: It's usually located near where the hose connects to the pool wall.)

Air in the System

Air bubbles are the enemy of pool cleaners everywhere. Air trapped in the plumbing system can create pockets of buoyancy, lifting your Polaris off the floor. It also reduces the efficiency of the pump and filter.

How to identify air in the system:

• Listen for gurgling sounds: If you hear gurgling or sucking sounds coming from your pump or filter, it's a good indication that air is present.
• Check the pump basket: Is the water level in the pump basket abnormally low? Are you seeing air bubbles swirling around?
• Observe the return jets: Are the return jets spitting out air bubbles?

Getting rid of air:

• Prime your pump: Make sure your pump is properly primed. This involves filling the pump basket with water before starting the pump. (Read your pump manual for specific priming instructions.)
• Check for suction-side leaks: Air is often drawn into the system through leaks on the suction side of the pump (i.e., the pipes that bring water to the pump). Inspect all fittings and connections for tightness. Especially around the skimmer!
• Clean your skimmer basket: A full skimmer basket can restrict water flow and cause the pump to suck in air. Empty it regularly. (Seriously, this is like the easiest pool maintenance task ever. No excuses!)

Buoyancy Issues

Sometimes, the problem isn't water pressure or air, but the Polaris itself! Certain parts can become overly buoyant, preventing it from staying submerged.

Possible causes of buoyancy problems:

• Worn-out floats: The Polaris 360 has several floats that help it navigate. If these floats become damaged or waterlogged, they can increase buoyancy. Inspect the floats for cracks, leaks, or signs of wear. Replace them if necessary.
• Trapped air inside the Polaris: Occasionally, air can become trapped inside the body of the Polaris. Try gently tilting and shaking the Polaris underwater to release any trapped air.
• Incorrect hose length: Having too much hose can cause excess buoyancy and prevent the cleaner from staying on the bottom. The correct hose length should allow the Polaris to reach all areas of your pool without excessive slack.
• Clogged filter screen inside the cleaner: Over time, the small filter screen inside the Polaris can become clogged with fine debris, which can also affect its buoyancy and performance. Remove the screen and clean it thoroughly.

Obstructions and Entanglements

Let's face it, pools can be obstacle courses. Toys, leaves, and even algae blooms can impede your Polaris's movement and cause it to get stuck or lift off the bottom.

Things to check for:

• Debris on the pool floor: Remove any large debris from the pool floor, such as leaves, twigs, or toys.
• Entangled hoses: Make sure the Polaris hose is not tangled or kinked. A tangled hose can restrict water flow and prevent the cleaner from moving freely.
• Obstructions around fittings: Make sure nothing is obstructing the swivel where the cleaner hose connects to the pool wall. This joint needs to move freely to allow the cleaner to navigate effectively.
• Algae build-up: In severe cases, an algae bloom can create a slick surface on the pool floor, making it difficult for the Polaris to maintain traction. Treat the algae bloom with the appropriate chemicals. (Algae is the bane of every pool owner's existence. Don't let it win!)

Worn or Damaged Parts

Pool cleaners are like any other mechanical device – they wear out over time. Worn or damaged parts can affect the Polaris's performance and cause it to lose suction or buoyancy.

Parts to inspect:

• Tires: Check the tires for wear and tear. Worn tires can reduce traction and make it difficult for the Polaris to climb walls or stay on the bottom. Replace them if necessary.
• Drive belt: The drive belt connects the motor to the wheels. If the belt is worn or broken, the wheels may not turn properly.
• Sweep hose (tail): Make sure the sweep hose is in good condition and properly attached. The sweep hose helps to stir up debris and direct it towards the intake valve. A damaged or missing sweep hose can reduce the cleaner's effectiveness.
• Backup valve: The backup valve is designed to prevent the Polaris from getting stuck in corners. If the backup valve is malfunctioning, it may cause the cleaner to jerk around erratically or even lift off the bottom.

The Polaris 360 Rebuild - Advanced Troubleshooting

Okay, if you've tried all the basic troubleshooting steps above and your Polaris is still stubbornly floating, it might be time for a deeper dive (still pun intended, sorry!). This section deals with more complex issues that might require a bit more technical know-how.

The Thrust Jet

The thrust jet is a crucial component that helps propel the Polaris 360 around the pool. If this jet is clogged or malfunctioning, it can significantly impact the cleaner's performance.

Checking the thrust jet:

• Visual inspection: Examine the thrust jet for any signs of blockage. Remove any debris that you find.
• Flow test: Disconnect the Polaris from the hose and turn on the pump. Observe the flow of water coming from the thrust jet. It should be a strong, steady stream. If the flow is weak or erratic, there may be a blockage inside the jet.
• Disassembly and cleaning: If you suspect a blockage inside the jet, you may need to disassemble it and clean it thoroughly. Refer to your Polaris 360 owner's manual for instructions on how to disassemble the thrust jet.

The Feed Pipe Assembly

The feed pipe assembly is the part that connects the cleaner to the hose and delivers the pressurized water. Problems with this assembly can lead to reduced water flow and, you guessed it, floating problems.

Inspecting the feed pipe assembly:

• Check for cracks or leaks: Inspect the feed pipe assembly for any cracks, leaks, or signs of damage. Replace it if necessary.
• Ensure proper O-ring seal: Make sure the O-rings that seal the feed pipe assembly are in good condition. Damaged or missing O-rings can cause leaks and reduce water pressure.
• Verify proper assembly: Ensure the feed pipe assembly is properly assembled and tightened. Loose connections can cause leaks and reduce water flow.

The Pressure Relief Valve (If Equipped)

Some Polaris 360 models have a pressure relief valve. This valve is designed to prevent excessive pressure from building up inside the cleaner. However, if the valve is stuck open or malfunctioning, it can bleed off too much pressure, causing the cleaner to float.

Testing the pressure relief valve:

• Visual inspection: Examine the pressure relief valve for any signs of damage or blockage.
• Manual activation: Try manually activating the pressure relief valve to see if it opens and closes smoothly. If the valve is stuck or sluggish, it may need to be cleaned or replaced.

Still Floating? Time to Call in the Pros

If you've tried all the troubleshooting steps outlined above and your Polaris 360 is still stubbornly refusing to stay on the bottom of the pool, it might be time to call in the professionals. A qualified pool technician can diagnose more complex problems and perform repairs that you may not be comfortable tackling yourself.

Remember, your local pool supply store is also a great resource. They can offer advice, sell you replacement parts, and even recommend reputable pool technicians in your area.
