Short answer
Should a hot tub owner buy rechargeable or corded?
Rechargeable suits short spot-cleaning sessions and tubs far from an outlet, since the two listings here state runtimes of up to 45 minutes and up to 1 hour. Corded suits long sessions where an outlet sits close to the tub, since it runs as long as it stays plugged in.
After a soak, leaves and sand settle on the floor of the tub, and the question is how to clear them without dragging a cord across wet decking. The choice between rechargeable vs corded hot tub vacuum power comes down to runtime against reach: a rechargeable model runs free of an outlet for a stated time, while a corded model runs as long as it stays plugged in but stays tied to the outlet. This guide sets out that trade-off and compares two cordless listings on runtime, heads, filters and size.

How rechargeable vs corded hot tub vacuum choices differ
A rechargeable vacuum carries its own battery, so it can be picked up and used around the tub without an outlet nearby. The limit is the stated runtime: the two listings here state up to 45 minutes and up to 1 hour of cleaning on a charge, and once the battery runs down, the vacuum needs charging before it can be used again. A corded vacuum has no such limit, since it draws power through its cord for as long as it stays plugged in, but its reach ends where the cord ends.
That trade-off points to different buyers. A buyer who spot cleans a hot tub in short sessions may never notice a runtime limit, while a buyer who cleans a larger pool in one long session may value the continuous power of a corded model.
What rechargeable gives you, from the two listings
Both listings here are cordless and rechargeable. The POOL BLASTER listing is made for spas, hot tubs and spot cleaning small above ground pools, while the AQUAFYSH listing covers above ground and inground pools as well as hot tubs. The POOL BLASTER listing describes a spa and hot tub vacuum with an 8-inch omni-directional head, push-button operation and an ergonomic grooved handle, for use by hand or fitted to a standard 1.25-inch pole. The AQUAFYSH listing describes a handheld cleaner with three heads, a magnet-drive system and fine mesh filters, for above ground and inground pools as well as hot tubs. Neither listing states a corded option, so this guide compares the rechargeable side in detail and sets out the corded side as the alternative.
Runtime is the clearest difference between the two: the POOL BLASTER listing states up to 45 minutes of continuous cleaning from its lithium-ion battery, while the AQUAFYSH listing states a runtime of up to 1 hour. Flow is stated only for the AQUAFYSH listing, at up to 18.9 gallons per minute.
What corded gives you
A corded vacuum trades freedom of movement for continuous power. With no battery to run down, it suits long cleaning sessions and larger areas, provided an outlet sits close enough to the tub for the cord to reach. The cord itself is the drawback: it must be routed so it does not trail across walkways or sit in standing water, and the vacuum cannot be carried beyond the cord’s reach.
Two rechargeable vacuums worth comparing
These are scored on the Chill Score, which weighs performance, build, value, safety and warranty. Neither listing states a safety certification or a warranty term, so both score zero on those two measures.
| Product | Chill Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| AQUAFYSH AQ70 | 9.5 | 30 | 21 | 21 | 0 | 0 |
| POOL BLASTER Catfish | 9.3 | 26 | 20 | 18 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

Choosing between them
- Match runtime to the job. The POOL BLASTER listing states up to 45 minutes, while the AQUAFYSH listing states up to 1 hour, so longer sessions point to the AQUAFYSH listing.

- Check filters and heads. The AQUAFYSH listing states three heads and filters rated at 25µm and 120µm, while the POOL BLASTER listing states one multilayer filter bag and one 8-inch head.
- Check size and weight. The POOL BLASTER listing states 2.94 Pounds and dimensions of 8.0 Inches x 7.25 inches x 15.2 inches, while the AQUAFYSH listing states 4.0 Pounds and dimensions of 21.0 Inches x 9.0 Inches x 8.0 Inches.
Common questions
Should a hot tub owner buy rechargeable or corded?
Rechargeable suits short spot-cleaning sessions and tubs far from an outlet, since the two listings here state runtimes of up to 45 minutes and up to 1 hour. Corded suits long sessions where an outlet sits close to the tub, since it runs as long as it stays plugged in.
How long does the POOL BLASTER Catfish Gen 2 run on a charge?
The listing states up to 45 minutes of continuous cleaning from its lithium-ion battery. It is a cordless model, so it needs charging once the battery runs down.
What does the AQUAFYSH AQ70 filter catch?
The listing states two fluff ultra fine mesh filters rated at 25µm and one durable nylon ultra fine mesh filter rated at 120µm, for sand, leaves and small particles. The filters do not need replacing during use until completely full, as stated.
Do these vacuums need a pole?
The POOL BLASTER listing states the pole is not included and that the vacuum fits all standard 1.25-inch pool poles, so a buyer who already owns one can use it. The AQUAFYSH title lists poles, and its listing describes three heads for brush cleaning, daily cleaning and narrow spaces.
Can either vacuum clean a small above ground pool?
The POOL BLASTER listing states it is for spas, hot tubs and spot cleaning small above ground pools. The AQUAFYSH listing states it is for above ground and inground pools as well as hot tubs.
