Nickel-metal Hydride Batteries
Nickel-metal hydride (NiMH) batteries are less common but still used. They have a good balance of cost and performance. NiMH batteries hold less charge than lithium-ion ones. These batteries weigh more, affecting vacuum portability. Charging time is longer compared to lithium-ion batteries. They do not perform well in very cold conditions.
Lead-acid Batteries
Lead-acid batteries are the oldest type found in some vacuums. They are heavier and bulkier than others. These batteries are cheaper but have a shorter run time. Lead-acid batteries take longer to charge fully. They work well for short cleaning jobs. They need regular maintenance to keep working properly.
Usage Impact On Runtime
Battery-powered hot tub vacuums do not run the same time every use. Runtime depends on how you use the vacuum. Different tasks and settings change how long the battery lasts. Understanding these factors helps you get the best use from your vacuum.
Cleaning Intensity
Vacuuming heavy dirt or large debris uses more power. The motor works harder and drains the battery faster. Light cleaning with small particles uses less energy. Running the vacuum gently extends battery life. Intense cleaning reduces how long the vacuum runs per charge.
Surface Types
Rough or textured surfaces need more effort to clean. The vacuum moves slower and uses more battery. Smooth surfaces require less power to clean. Soft surfaces like spa liners may also affect runtime. Hard floors help the vacuum last longer on a charge.
Vacuum Settings
Most battery vacuums have speed or suction settings. Higher suction uses more battery power quickly. Lower settings save battery and increase runtime. Choosing the right setting for your cleaning needs is key. Adjust settings to balance cleaning strength and battery life.
