Pentair Kreepy Krawly Legend Review

Pentair LL505G Kreepy Krauly Legend Pressure-Side Pool Cleaner Review: A Legend or Just a Myth?

I've had my eye on the Kreepy Krauly Legend for years. It's the cleaner a lot of pool owners grew up with, and Pentair sells it as a workhorse for lighter-colored in-ground pools. So I dropped one in my own pool and ran it for a full month to see if the name still holds up.

On paper it has everything the old guard loves: four-wheel design, a big debris bag, and a dedicated booster pump doing the heavy lifting. That combo used to be the gold standard. But I've tested enough robots at this point to know the game has changed, so here's exactly what I found running the Legend day after day, and how it stacks up against what I'd actually buy today.

Setup and Installation: Not for the Faint of Heart

Getting the Legend going is a project, plain and simple. Like every pressure-side cleaner I've tested, it won't do a thing without a dedicated booster pump. I already had one plumbed into my pool, so I was fine. But if you don't, you're looking at buying the pump and probably paying somebody to install it before this cleaner ever touches the water.

That's the part that always gets me. I can unbox a robot, drop it in, and plug it into a wall outlet in about two minutes. With the Legend, you're wiring in a whole second pump first. The gap in convenience is hard to ignore once you've lived with both.

Which booster pump does the Pentair Kreepy Krauly work with?

I ran mine off the Polaris PB4-60 that was already installed in my pool, and it drove the Legend without a single hiccup.

If you'd rather stick with a Pentair-brand pump, here are the two I'd point you toward:

Pentair Booster Pump for pressure side pool cleaners EC-LA01N

Pentair FBA_LA-MS05 LA-MS05, Black

Any of those three will get the Kreepy Krauly moving just fine.

The Hose Assembly

You also get a 30-foot hose assembly, which was plenty for my pool and should cover most medium-sized ones. If your pool is on the bigger side, that length starts to feel short. Laying the hose out so it doesn't tangle and actually reaches every corner took me a couple tries to get right. The flow adjustment is its own little puzzle, too. I had to tweak it several times over the first few days before the Legend was tracking and cleaning the way it should. That's not a five-minute setup, and I want to be honest about it.

Cleaning Performance: Effective, But Far from Perfect

The four-wheel design with front-wheel drive does give the Legend solid traction. I ran it on concrete and vinyl, and it held its footing on both without spinning out. In theory that grip should let it climb from the floor up onto the walls and hit everything. In practice? I'll be blunt: the cleaning was just "meh."

Big stuff, it handles fine. Leaves, acorns, twigs, the Legend scooped those up no problem. Where it fell apart was the fine debris. Sand, silt, pollen, that single-jet propulsion just doesn't have the juice to stir it up and pull it in, so I kept finding a fine film left behind. In my lighter-colored pool that residue really stood out. It also missed spots, especially up on the vertical walls and around the steps and tight corners where it couldn't quite maneuver in.

The thing that wore on me most was how often it got stuck. My Legend kept wedging itself against the ladder and the steps and just sitting there until I walked over and freed it. Newer robots read the pool and steer around obstacles, then plan out an efficient path. The Legend has none of that. It bounces around on a random pattern, so it'll clean the same stretch three times and skip another patch entirely.

Debris Bag and Filtration: Room for Improvement

Pentair leans hard on the big debris bag as a selling point, and honestly, I get why. It's noticeably bigger than what you get on the Polaris Vac-Sweep 280 or 360, so I wasn't running to empty it constantly. That part I genuinely liked.

The execution around the bag, though, is where it lost me. Pulling it off and getting it back on takes both hands and a bit of patience, and emptying it can turn into a mess, especially when it's packed with fine debris that sticks to the sides. I ended up rinsing it out more than I expected.

The mesh does its job on the big stuff, but fine particles slip right through and settle back into the pool. So I'd run the Legend and then still find myself grabbing a manual vacuum to finish the job, which kind of defeats the point of buying an automatic cleaner. On top of that, the bag wears out. Plenty of owners report having to replace it fairly often, and that's a recurring cost you should factor in.

Energy Consumption: High and Inefficient

Here's the one that hits your wallet. The Legend leans on that booster pump, and the pump has to run at the same time as your main filtration pump. So you've got two pumps pulling power every time you clean. I noticed it, and compared to the robots I run, the energy draw is in a different league. It costs more to operate and it's tougher on the environment. If you're trying to trim your electric bill or shrink your footprint, a pressure-side cleaner like this is working against you.

The robots I test sip power by comparison, and most of them let you set a schedule so they only run when they need to. The Legend has zero programming. I had to walk out and switch it on, then remember to switch it off. That's a small thing day to day, but it adds up, and it means the cleaner is often running longer than it needs to.

Durability and Maintenance: A Few Red Flags

Durability is a mixed bag, and it's part of why I think the "Legend" name is generous. Pick the thing up and it feels sturdy, no argument there. But the internals, the gears and the wheels, wear down over time. That front-wheel drive works great out of the box, but from what I've seen and heard from other owners, it can get sluggish or quit entirely after a few seasons, especially if you run it hard or skip the upkeep.

The bag and hose are the other soft spots. Like I said, the bag tears and you'll be buying replacements. The hose stays flexible for a while, but sun and pool chemicals eventually make it brittle, and then you get leaks or cracks. That's the trade-off with a cleaner built around this many mechanical parts: more pieces means more chances for something to break. You'll need to check and clean the internal gears now and then to keep it happy, and if you're after a set-it-and-forget-it cleaner, that's not this.

Usability: Lacks Modern Conveniences

I'll be honest, using the Legend felt like stepping back in time. No app, no schedules, no remote. You get exactly one control, and that's the booster pump switch. There's no way to set a cleaning cycle or check on it from your phone, and those are features I now take for granted on most of the robots I test.

The design doesn't help either. Between the bulky bag and the hose that likes to tangle, the whole rig is a bit of a handful to move around, and with no automation you're doing more of the work yourself. If you've gotten used to how easy a good robot is, the Legend is going to feel like a downgrade.

How We Tested the Pentair LL505G Kreepy Krauly Legend

I ran the Legend for four full weeks across two different in-ground pools, one with a light-colored vinyl liner and one with a concrete surface, so I could see how it handled both. I let real debris pile up the way it does in the summer: leaves, twigs, dirt, and bugs. No staged tests, just the actual mess my pool collects.

Here's what I was watching for:

• Ease of Installation: I timed the setup and noted every headache, including the booster pump and getting the hose and debris bag assembled.

• Cleaning Performance: I watched how it moved across each surface and how well it actually pulled up different kinds of debris. I paid extra attention to the spots cleaners usually blow, like steps, corners, and the waterline.

• Energy Efficiency: I looked at how much power the main pump and booster pump pulled together during a cleaning cycle, then compared that to the robots I've run.

• Durability and Maintenance: I judged the build quality and how often I had to fuss with it, including how quickly parts like the bag, hose, and gears wear out.

After a month with it, my takeaway is that the Legend gets the job done in a basic way but falls behind anything modern. It struggled with fine debris, made me step in by hand more than I'd like, and burned through noticeably more electricity than the robots I test. It's just not as efficient as what's out there now.

Final Verdict: Is the Pentair LL505G Kreepy Krauly Legend a "Legend" in Name Only?

So where does that leave the Legend? It does have real strengths. It's built solid and it eats large debris for breakfast. But the list of drawbacks is long: fussy setup, weak on fine debris, thirsty for power, and none of the modern features I've come to rely on. In today's market, that's a hard sell.

If you already own a pressure-side setup with a booster pump plumbed in, and your pool mostly deals with leaves and big debris, I can see the Legend still earning its keep. But if what you want is convenience, lower running costs, and smarter cleaning, I'd steer you toward a robotic cleaner every time.

Rating: ★★☆☆☆ (2.5/5)

The Legend has its moments, but honestly, it gets buried by the better robotic options I test these days. The name still carries weight. The performance no longer does.
