10 Best Hot Tub Vacuums 2025 in the United States

The Lydsto S1 Lite cordless hot tub vacuum is a great option if you want a lightweight, easy-to-use cleaner for small debris in spas and hot tubs. It runs on a rechargeable lithium-ion battery that lasts up to 90 minutes, which is quite generous for one charge and gives you plenty of time to clean without being plugged in. The 20W brushless motor provides solid suction for picking up dirt, sand, and fine particles, and it filters water efficiently at about 660 gallons per hour using a fine 120-mesh filter that helps trap small debris.

The vacuum includes three types of cleaning heads—a triangular brush, a round brush, and a long extendable pole reaching 5.6 feet—which makes it versatile for cleaning corners, steps, and hard-to-reach spots. It's also designed with safety in mind, automatically shutting off if water flow stops, and it can handle water temperatures up to 95°F, which is typical for hot tubs. The dustbin capacity is 0.33 liters, so it’s best for quick cleanups rather than heavy-duty or large-volume cleaning sessions. This vacuum is lightweight at just over 3 pounds and assembles in a couple of minutes, making it convenient for frequent use.

The small capacity means you might need to empty it often during bigger cleans, and while the suction is good for small debris, it may struggle with larger or heavier dirt. If you want a quiet, cordless vacuum that’s easy to handle and designed specifically for spas and hot tubs, the Lydsto S1 Lite fits well. It’s not the best choice if you need a heavy-duty cleaner for large pools or lots of debris, but for its category, it offers a user-friendly and effective cleaning experience with a helpful one-year warranty for peace of mind.

The KOKIDO Rechargeable Handheld Pool Vacuum Set is designed to clean above-ground pools, hot tubs, and small pools up to 20 feet, making it a versatile choice for different water bodies. One of its strengths is the cordless convenience, powered by a lithium rechargeable battery that provides about 40 minutes of cleaning time per charge. This eliminates the hassle of dealing with wires and offers silent operation, which is a plus for those who value peace and quiet.

The vacuum is lightweight, weighing less than 3 pounds, making it easy to handle, and comes with a 72-inch adjustable aluminum pole that helps reach narrow spaces and corners effectively. The 2 interchangeable brush heads add to its maneuverability and versatility in tackling various types of debris, such as leaves and sand. Additionally, it has a compact design which makes it easy to store and manage.

On the downside, the vacuum’s capacity is only 0.1 gallons, which may require frequent emptying during use, and the 5-hour charging time might be inconvenient for some users. The suction power, while consistent, may not be as strong as some larger, more powerful models, making it more suitable for spot cleaning rather than extensive cleaning sessions. The product also comes with a 1-year warranty and positive customer feedback, indicating reliable customer service. However, assembly is required, which might be a slight inconvenience for some users. This product is ideal for pool and hot tub owners looking for a lightweight, easy-to-use, and cordless option for quick and efficient spot cleaning.

The Kokido 2025 Cordless Pool Vacuum is a lightweight and easy-to-handle option designed especially for small pools, spas, and hot tubs up to about 20 feet. It runs on rechargeable lithium-ion batteries, providing about 50 minutes of cordless cleaning time, which allows convenient access to every corner without worrying about power cords. The vacuum delivers steady suction of 16 gallons per minute, sufficient to pick up common debris like sand, gravel, and small leaves, although it is less effective for very fine particles like algae or large debris over 3 inches.

Its dual filtration system features two interchangeable filters: a durable steel one for larger debris and a fine mesh one for smaller particles, helping keep the water clearer. The vacuum includes two heads—a pivoting triangular head for general cleaning and a flat brush for tight spots—making it versatile for different surfaces and areas in your tub or pool. The 72-inch aluminum pole allows cleaning with less bending, and the tool is compact and light at just 3.5 pounds, making it easy to maneuver even with one hand.

The waterproof design enables operation in both warm and cold water. While the small debris capacity of about 0.15 gallons means frequent emptying during larger cleaning sessions, the vacuum serves well as a spot cleaner or a supplement to robotic pool cleaners, especially for quick touch-ups in hot tubs or small pools. Assembly is required, and the product comes with a one-year warranty and solid customer support, ensuring a reliable experience.
