Why Your Poolvergnuegen Pool Cleaner Won't Climb Walls
We get this call a lot. The Poolvergnuegen (now sold as Hayward's The Pool Cleaner) covers the floor fine, but it never goes up the walls anymore. The good news is this is one of the easier pool cleaner problems to fix, and most of the time you don't need a new cleaner.
A Poolvergnuegen that won't climb walls almost always has one of three problems: worn tires, weak suction, or worn skirts. Below is how to check each one, in the order we'd check them in the shop.
Why won't my Poolvergnuegen climb the walls?
Short answer: the cleaner has lost either its grip or its power. Grip comes from the rubber tires and the skirts underneath. Power comes from water flow through your suction line. When any of those wear down, the cleaner keeps working on the flat floor but gives up on the walls, because climbing is the hardest thing you ask it to do.
Wall climbing is the first thing to go when parts wear out. Think of it as an early warning. If you ignore it, floor coverage usually starts to suffer next.
Check the tires first
Worn tires are the number one reason a Poolvergnuegen stops climbing. Look at the small ridges (the humps) on the tires. When those humps are worn smooth, the cleaner can't grip the wall, no matter how strong your suction is.
Here's a quick test. Grab the cleaner and look at the tire tread from the side. Fresh tires have clear, raised humps. If yours look rounded off or slick, that's your problem. Replacement front tires with super humps (part 896584000-143) are cheap compared to a new cleaner, and swapping them takes a few minutes with no tools. They just stretch over the wheel.
One more thing while you're there: spin each wheel by hand. All wheels should turn together with steady resistance. If one spins free or feels gritty, the internal bearings or drive parts are worn, and a tune-up kit that includes new tires, bearings, and wear parts is the better buy.
Is your suction strong enough?
If the tires look fine, weak flow is the next suspect. A Poolvergnuegen needs a steady amount of water moving through it to press itself against the pool surface and drive the wheels. Not enough flow, and it crawls along the bottom but can't fight gravity on the wall.
Run through this list:
- Empty the pump basket and skimmer basket. A half-full basket steals more flow than people expect.
- Clean or backwash your filter. A dirty filter is the most common cause of low suction.
- Check the hose for cracks or loose connections. Any air leak kills climbing power fast.
- If you're running a variable speed pump, bump the RPMs up while the cleaner runs. Many pumps are set too low for a suction cleaner to climb.
- Check the regulator valve at the wall or skimmer connection. If it's stuck open, it's bleeding off the suction your cleaner needs.
Hayward makes a suction kit for the Poolvergnuegen (part PVGSCKIT244) that includes a fresh regulator valve, hose cone, and fittings. If your connections are old, cracked, or missing pieces, this one kit replaces all the usual leak points at once.
Don't forget the skirts
The rubber skirts on the underside of the cleaner create the seal that lets suction hold the unit against the wall. Worn or torn skirts break that seal, so the cleaner slides back down even with good tires and good flow.
Flip the cleaner over and look at the skirt edges. They should be straight and flexible. If they're curled, cracked, or worn thin, replace them. Skirt kits (like part 896584000-105 for the 4-wheel models) cost less than a filter cleaning and take minutes to install.
Still not climbing after all that?
If you've replaced the tires, checked the skirts, and confirmed strong suction, and your Poolvergnuegen still won't climb walls, the drive train inside the cleaner may be worn out. At that point, compare the cost of a full rebuild against a replacement cleaner head. On an older unit that's been running for many seasons, the replacement head often makes more sense.
But start with the simple stuff. In our experience, the majority of these calls end with a set of tires or a suction fix, not a new cleaner.
