Before purchasing this pond vacuum cleaner, I requested an estimate from a local pond service company to clean my pond and they quoted me $3,000.00 for one time cleaning. Fortunately, they kept missing the appointment so I decided to buy this vacuum. After one use, I can honestly say it is worth the money and saved me a lot of money. The suction is very strong and sucked up the thick algae growing on the flagstones. The inlet or suction hose is long enough to reach the bottom and all around the entire pond. The discharge hose is also long enough and able to reach a nearby garden, so it watered my plant. I like the fact that it pauses for a few seconds which is enough time to reposition the hose. I highly recommend it.
