Hayward Wanda The Whale Suction Above-Ground Pool Cleaner

The Verdict

If you own an above-ground pool, you already know the drill: brushing walls, vacuuming floors, and wrestling with a manual vacuum head. The Hayward Wanda the Whale promises to end that chore. At a 4.0-star average across 200 ratings, it’s not perfect — but it might be the best $150-ish you’ll spend on pool maintenance this season. Let me tell you why.

What You Actually Get

Inside the box: the Wanda unit itself (model Wanda the Whale, part number WandaW), a 32-foot suction hose, a hose adapter that connects to your skimmer, and a flow gauge to help you dial in the right suction. That’s it. No booster pump, no power cord, no wall-mounted control unit. The whale-shaped body measures about 15 inches long and 10 inches wide, and at under 6 pounds, it’s light enough to toss in and out of the pool without a workout.

How It Performs in Real Pools

Wanda works by attaching to your pool’s skimmer suction line. Water flows through the unit, creating a venturi effect that pulls debris into the pump’s strainer basket. The design — that curved tail and the wide mouth — lets it crawl along floors, up walls, and even navigate the dreaded cove corners where above-ground pools meet the bottom.

Here’s the honest part: it’s not a set-and-forget robot. You need to dial in the flow. Too much suction and it’ll stick to the floor like a limpet. Too little and it wanders aimlessly. The included flow gauge helps, but you’ll spend the first few days adjusting your pump’s valve settings. Most users find a sweet spot around 1,000–1,200 GPH, which means running your pump on medium-to-low rather than full blast.

When dialed in correctly, it picks up sand, leaves, and fine silt effectively. One reviewer noted, “It cleans my 18-foot round pool in about two hours. I just toss it in, set the pump on low, and forget it.” Another mentioned it handles the wall-to-floor transition better than previous suction cleaners they’d tried.

Where It Falls Short

The 32-foot hose is the biggest complaint. If your pool is larger than 24 feet across, you’ll need to buy an extension (about $15–20). Not a dealbreaker, but an extra cost nobody mentions.

Second, there’s no onboard debris collection. Wanda pushes everything into your pump’s strainer basket. That means you’ll be cleaning that basket more frequently — sometimes twice a day during heavy leaf season. If you have a sand filter, this is fine. If you have a cartridge filter, prepare for more frequent backwashing.

Third, the connector to the skimmer can be finicky. Some users report leaks at the connection point if the adapter isn’t seated perfectly. A little plumber’s tape solves it, but it’s an annoyance on first installation.

Who Should Buy This

This is perfect for owners of smaller above-ground pools (12–24 feet) who want to cut down manual vacuuming without spending $400+ on a robotic cleaner. It’s also great for seasonal pool owners who don’t want to maintain complex equipment — there are no filters to replace, no rechargeable batteries to degrade, and it stores flat for winter.

Skip it if you have a pool over 28 feet, if you have a single-skimmer setup with a weak pump (under 1 HP), or if you’re looking for a hands-off solution that handles everything without adjustment. This requires a bit of tuning and occasional babysitting.

FAQ

Q: Will this work with my pool’s existing pump? A: Yes, as long as you have a skimmer with a suction line. It works with most above-ground pumps rated at 0.5 HP or higher. If your pump is weaker, you’ll struggle to get enough flow.

Q: How often do I need to run it? A: For a 15-foot round pool, most users run it daily for 1–2 hours. For a 24-foot oval, plan on 3–4 hours. It’s not a 24/7 cleaner — it’s efficient enough to do the job and then you pull it out.

Q: Does it climb walls? A: Yes, partially. It climbs up to about 6 inches above the waterline on the walls, which is enough to catch the scum line and prevent buildup. It won’t scrub the tile line, but it prevents heavy algae growth at the water surface.

The Verdict

Buy it if: You have a 12–24 foot above-ground pool, don’t mind spending 15 minutes setting the flow correctly, and want to eliminate most manual vacuuming for around $150.

Skip it if: You have a pool over 28 feet, a weak pump, or you want a truly hands-off robotic cleaner that handles everything without adjustment. This is a tool, not a miracle worker.

Rating: 4.2/5 — Solid performance for the price, with a few quirks that are easily managed. It’s not the fanciest pool cleaner on the market, but it’s honest, effective, and won’t empty your wallet. For the average above-ground pool owner, that’s a winning combination.
