7 Best Electric Hot Tub Vacuums to Buy in 2025

This game-changing cordless hot tub vacuum delivers pro-level suction and blazing-fast charging, making it a top-tier choice for spa owners who demand efficiency. With its 40W high-power motor and 18.5 gallons per minute flow rate, it effortlessly lifts sand, silt, and stubborn debris from spa floors.

In real-world testing across inflatable spas and full-size inground hot tubs, the 7-foot telescopic pole proved invaluable for reaching deep corners without leaning over the edge. The IPX8 waterproof motor stayed cool and quiet even during 45-minute continuous runs, though performance dips slightly in water above 95°F. While the 500-mesh reusable filter bags captured fine particles effectively, they required mid-clean rinsing in heavily soiled tubs—something to watch if tackling neglected spas.

Compared to the budget POOL BLASTER Aqua Broom, the Teguy offers superior power and faster recharge, but at a higher cost and slightly shorter runtime (60 mins vs 3 hours). It’s ideal for frequent users who value quick turnaround and strong suction over marathon battery life. For those upgrading from manual cleaning or older battery models, this vacuum delivers cutting-edge performance with the reliability of smart safety systems, outpacing entry-level options in both speed and cleaning intensity.

Don’t let its ultra-affordable price tag fool you—the POOL BLASTER Aqua Broom punches well above its weight when it comes to deep-cleaning fine contaminants in hot tubs and spas. Its patented retention valve is a quiet hero, ensuring zero debris blowback after suction, a common flaw in budget vacuums. Designed for sand, silt, and micro-dirt, it excels in maintaining water clarity between chemical treatments, solving the nagging issue of cloudy spa floors.

Powered by five D-cell batteries, it delivers up to 3 hours of runtime, making it a champion of endurance for small spas and inflatable pools. In testing, it handled 4-foot-deep spas with ease, though the lack of a telescopic pole (sold separately) made cleaning center areas awkward without leaning in. The ultra-lightweight body (under 2 lbs) made it easy to maneuver by hand, but the plastic housing feels less durable than premium models—especially when dropped on hard surfaces.

When stacked against the Lydsto S1 Lite, it offers longer runtime but less motorized power and filtration control. It’s the go-to for casual spa owners or those needing a backup vacuum for spot cleaning. While it lacks modern USB charging and brushless motors, its no-frills reliability and unbeatable runtime make it a standout budget pick—delivering core functionality without overcomplication, outlasting pricier models in sheer operational hours per dollar.

Meet the endurance king of electric hot tub vacuums—the Lydsto S1 Lite goes the distance with a 90-minute runtime that crushes competitors relying on standard 60-minute batteries. Its 20W brushless motor delivers whisper-quiet performance while filtering over 660 gallons per hour, making it ideal for deep-cleaning larger spas without constant recharging. The included 5.6-foot aluminum pole and dual brushes (round and triangular) turn tight corners and steps into easy wins, solving the common pain point of hard-to-reach spots.

During extended cleaning sessions in 6-person hot tubs, the automatic 5-second motor shutoff during blockages prevented overheating—a smart safety layer absent in many budget models. The 120-mesh fine filtration captured silt and fine sand effectively, though it struggled slightly with larger organic debris like leaf fragments. While the 3-hour recharge time is a trade-off, the long cleaning window more than compensates for frequent or thorough users. It performs best in moderate debris loads and maintains consistent suction, even in warmer spa water up to 95°F.

Compared to the Teguy model, it offers longer runtime and quieter operation, but less raw suction power (20W vs 40W). It’s perfect for weekend warriors and maintenance-focused users who prioritize cleaning duration and included accessories over brute force. For those who hate stopping mid-clean, this vacuum delivers uninterrupted performance with greater value in included tools, outperforming similarly priced models in completeness and runtime.

If raw cleaning power is your priority, the Lydsto S1 2025 stands tall with a 30W high-performance motor that churns out 13.6 gallons per minute and 14,000 RPM—a true beast for tackling sandy spa floors and post-party messes. Its dual-phase debris capture system combines a 1.3L large dust box with a 120-mesh nylon filter and sponge, enabling one-pass cleaning of mixed debris types. This dual-head design—featuring a vacuum head and floor brush—adds versatility, letting you scrub textured surfaces or glide over smooth spa bottoms with equal ease.

In real-world use, the reinforced telescopic pole held firm even when extended to its max, resisting wobble during edge cleaning—a common complaint with flimsier models. The 60-minute runtime handled full 7-foot spas with room to spare, though heavy silt loads required mid-clean filter rinsing. The push-button control and submersion indicator light added user confidence, ensuring the motor only ran when properly submerged. However, the 4.5–5 hour recharge time felt sluggish compared to faster-charging rivals.

Against the KOKIDO XV110, it offers stronger suction and larger debris capacity, but trades off in weight and noise. It’s the ideal choice for larger spas or frequent users dealing with sand, silt, and fine organic waste. For those who want maximum debris capture in a single run, this vacuum delivers professional-grade performance with smart usability, outclassing lighter models in sheer cleaning authority.

This ultra-specialized hot tub vacuum shines where others fail—capturing fine debris and surface oils that cloud spa water and clog jets. Its 25µm ultra-fine mesh filters go beyond standard filtration, trapping microscopic particles and even lotions and skin oils, thanks to the included oil absorbers—a rare and valuable upgrade in this category. The magnetic drive system eliminates seal wear, boosting longevity and efficiency, making it a smart long-term investment for high-use spas.

With a 380 GPH flow rate and 90-minute runtime, it matches top performers in endurance while delivering consistent, low-maintenance suction. The spa-specific cleaning head boosts suction by 20% in shallow water (0.6 ft), making it perfect for spot-cleaning waterlines and steps. In testing, it excelled in post-soak cleanup, removing oily films that other vacuums simply redistribute. However, the lack of auto-shutoff raises concerns about dry-run damage—users must stay vigilant to avoid accidental activation outside water.

Compared to the POOL BLASTER Aqua Broom XL, it offers finer filtration and oil removal, but less debris volume capacity. It’s best for luxury spa owners who prioritize water purity and chemical balance over large debris haul. For those battling cloudy water or scum lines, this vacuum delivers niche expertise with advanced filtration, outperforming generalists in targeted maintenance.

The KOKIDO XV110 redefines lightweight efficiency in cordless hot tub cleaning, tipping the scales at under 3 pounds—making it the easiest to maneuver in one-handed use. Its 60dB quiet operation ensures cleaning doesn’t disrupt household peace, a rare perk in motorized models. Despite its compact frame, the 10 GPM flow rate (20% higher than prior models) delivers surprisingly strong suction for sand and fine grit, especially when paired with the interchangeable brush heads for corners and steps.

In practice, the 72-inch aluminum pole provided excellent reach for 5–7 ft spas, and the IPX8 waterproofing gave confidence during full submersion. The 60-minute runtime supported multiple spot cleans, though continuous deep cleaning pushed it to the limit. It struggled with leaf fragments or heavy silt, best suited for light maintenance rather than deep rehab jobs. Its automatic power-off when not submerged added safety, but the motor isn’t brushless, hinting at shorter lifespan under heavy use.

Against the Lydsto S1 Lite, it’s lighter and quieter, but offers less runtime and filtration finesse. It’s perfect for occasional users or small spas who want a no-fuss, grab-and-go cleaner. For those already using a robotic cleaner, this vacuum excels as a precision touch-up tool, outperforming bulkier models in agility and convenience for quick fixes.

When debris volume is the main challenge, the POOL BLASTER Aqua Broom XL Ultra dominates with a 3X larger debris capture capacity and a 30% bigger vacuum head—a game-changer for spas after heavy use or leaf fall. Its patented retention valve ensures zero backflow, so once dirt’s in, it stays in—solving the frustration of re-circulated grime. The included three-piece pole set (34.25”) adds instant usability, letting you start cleaning without extra purchases.

Powered by five D-cell batteries, it runs up to 2.5 hours, bridging the gap between budget and premium models. In testing, it handled sand, hair, and small leaves with ease, though the plastic construction felt less rugged than metal-shaft rivals. The lightweight design (under 3 lbs) made overhead cleaning manageable, but the non-telescopic pole limited reach in larger spas. It’s best for step zones, shallow ends, and spot cleaning rather than full deep cleans.

Compared to the standard Aqua Broom, it offers more capacity and included poles, but still lacks USB charging or advanced filtration. It’s ideal for owners of mid-sized spas or pool steps who face moderate-to-heavy debris loads. For those needing high-volume pickup without cord hassles, this vacuum delivers practical power with real-world convenience, outshining smaller models in sheer hauling ability.
