Quick verdict
The versatile middle ground — Catfish nimbleness with more power and capacity. A smart one-vac pick for mixed spa-and-small-pool use.
Ideal for
- Mixed spa + small-pool cleaning
- Owners who found the base Catfish underpowered
- One-handheld households
Not ideal for
- Large in-ground pool floors (get the Max)
- Absolute lowest budget
The full picture
The Catfish Ultra Gen 2 bridges the gap between the nimble Catfish and the workhorse Max. It keeps the light, cordless, hose-free design that makes the Catfish so easy, but adds meaningfully more suction and a larger debris capacity than the original Ultra — enough to handle not just spa touch-ups but occasional pool-floor and step cleaning without bogging down. For an owner who wants one handheld that's spa-friendly yet capable of a bit more, it's a smart middle ground. It's pricier than the base Catfish but cheaper than the Max, and for many mixed spa-and-small-pool situations it's the sweet spot.

The in-depth review
The Catfish Ultra Gen 2 bridges the gap between the nimble Catfish and the workhorse Max.
The best of both
It keeps the light, cordless, hose-free design that makes the Catfish so easy, but adds meaningfully more suction and a larger debris capacity than the original Ultra — enough to handle not just spa touch-ups but occasional pool-floor and step cleaning without bogging down. For an owner who wants one handheld that's spa-friendly yet capable of a bit more, it's a smart single purchase.
The tradeoffs
It's pricier than the base Catfish but cheaper than the Max, and it's still slower than a wide-head Max on big floors. Heavy sand loads remain a job for the Max. Think of it as a capable all-rounder rather than a specialist at either end.

Frequently asked questions
How is the Gen 2 different from the original Catfish Ultra?
Gen 2 adds more suction power and a larger debris capacity, so it handles bigger messes and a bit more runtime before you empty it — a worthwhile upgrade if you clean more than just a spa.
Catfish Ultra or Pool Blaster Max?
The Ultra is lighter and more spa-friendly; the Max has a wider head and more suction for clearing full pool floors. Choose the Ultra for mixed spa-and-small-pool use, the Max for a larger pool.
Can it do a whole small pool?
Yes, reasonably — the added power makes small above-ground and in-ground pools manageable, though a big pool is still faster with a wide-head Max or a robot.
Does it handle sand?
Light sand and silt, yes; very heavy sand is better for the Max. The Ultra is a capable all-rounder rather than a dedicated heavy-debris tool.
Is it a good one-and-only handheld?
For many owners, yes — it’s nimble enough for spas and powerful enough for light pool duty, which makes it a versatile single purchase.
How do I maintain it?
Rinse the filter bag after use and recharge. The larger-capacity bag means fewer mid-clean empties than the base Catfish.
