How the Two-Chamber System Works:

The PondoVac 4's innovative design uses two chambers that work in alternating cycles. While Chamber A fills with debris and water, Chamber B drains via gravity. When Chamber A is full, the system automatically switches—Chamber A drains while Chamber B fills. This alternating action provides continuous suction, so you never have to stop cleaning and wait for the tank to empty.

Frequently Asked Questions

Q: How does the PondoVac 4 compare to the PondoVac Classic and PondoVac 5?
A: The PondoVac 4 sits between the Classic and the 5 in terms of performance and price. The PondoVac Classic (single chamber, 800 GPH) cycles on and off, requiring patience. The PondoVac 4 (two chambers, 1,300 GPH) provides continuous operation by alternating between chambers—much faster than the Classic. The PondoVac 5 (dual pumps, 2,100 GPH) offers true continuous operation with simultaneous vacuuming and discharge, making it the fastest but also the most expensive. The PondoVac 4 is the sweet spot for homeowners who want continuous operation without the premium price of the PondoVac 5.

Q: Do I have to do anything when the chambers switch, or is it automatic?
A: It's completely automatic! The PondoVac 4 handles the chamber switching for you. You'll notice a brief pause (just a second or two) as the system switches from one chamber to the other, but you don't need to do anything—just keep moving the suction tube around your pond. The vacuum automatically manages which chamber is filling and which is draining. This makes it much easier to use than single-chamber vacuums where you have to wait 20-30 seconds for each drain cycle.

Q: Can the PondoVac 4 handle the same tough jobs as the PondoVac 5?
A: Yes, the PondoVac 4 comes with the same 5 professional tool attachments as the PondoVac 5, including the Large Gravel Tool and String Algae Nozzle. It can handle gravel cleaning, string algae removal, and all the same tasks—it just has less suction power (1,300 GPH vs. 2,100 GPH). For small to medium ponds, the PondoVac 4 is more than adequate. The PondoVac 5 is better for very large ponds, extremely heavy debris loads, or professional use where maximum speed is important.
