Laifoo Aquarium Vacuum Gravel Cleaner is an alternate faucet-based option on the list of the ten best fish tank vacuums. It comes with a faucet connector and a 25-feet hose. The connector has a valve to switch between vacuuming and refilling operations. A siphon ball allows you to remove the water automatically with a few presses. You can remove the siphon ball once the water starts to flow for improving its flow rate. Its gravel tube has a filter screen for preventing gravel or fish from being sucked while removing debris. The tubing itself is odorless and won’t kink over time.
