Quick verdict
The nimble spot cleaner for spas, steps, and corners. Light and precise — not for whole-pool floors, but ideal for touch-ups.
Ideal for
- Hot tubs and spas
- Pool steps, benches, and corners
- Quick spot cleanups
Not ideal for
- Vacuuming a whole in-ground pool floor
- Heavy sand loads (get the Max)
The full picture
Where the Max is a floor-clearing workhorse, the Catfish is the precision tool. At just under 3 pounds with a 7.5-inch head and a soft-bristle brush, it's made for spot-cleaning the places a bigger vacuum (or a robot) can't reach well: hot tubs, spa benches, tight corners, and pool steps. The lithium battery runs up to 45 minutes — plenty for a spa or quick touch-up — and it comes with reusable and disposable filter bags. It's not the tool for vacuuming a whole in-ground pool floor, but for keeping a spa spotless or knocking out a small mess without dragging out anything bigger, it's the easy, affordable pick.

The in-depth review
Where the Max is a floor-clearing workhorse, the Catfish is the precision tool.
Built for spots, not floors
At just under 3 pounds with a 7.5-inch head and a soft-bristle brush, it's made for spot-cleaning the places a bigger vacuum or a robot can't reach well: hot tubs, spa benches, tight corners, and pool steps. The lithium battery runs up to 45 minutes — plenty for a spa or quick touch-up — and it includes reusable and disposable filter bags so you can start out of the box.
Where it holds back
It's not the tool for vacuuming a whole in-ground pool floor — the narrow head makes that tedious — and its moderate suction handles light silt but not heavy sand. Those aren't flaws so much as focus: this is a spot vacuum, and it's a very good one.

Frequently asked questions
Is the Catfish good for a hot tub?
Yes — it’s one of the best spot vacuums for spas and hot tubs. Its small, light body and soft-bristle head get into benches and corners a bigger vacuum can’t, and 45 minutes is ample for a spa.
Can it vacuum my whole pool?
A small above-ground pool, slowly. For a full in-ground pool floor, the narrow head makes it tedious — step up to the wider Pool Blaster Max, and keep the Catfish for spots and steps.
Does it pick up sand?
Light silt and dirt, yes; heavy sand loads are better handled by the higher-suction Max. The Catfish is tuned for spot cleaning, not bulk debris.
Catfish or Catfish Ultra?
The Ultra (especially Gen 2) adds power and capacity for a bit more debris and runtime. If you only clean a spa, the standard Catfish is plenty; for occasional pool duty too, the Ultra is worth the step up.
What’s included?
It comes with the vacuum, soft-bristle head, wall charger, and both reusable and disposable micro-filter bags, so you can start cleaning out of the box.
How do I clean it?
Rinse or swap the filter bag after each use and recharge. Its small size makes rinsing quick — part of why it’s such a low-fuss spa tool.
