"Fairly easy set up."

It eliminates spilled and dripping water on my carpet and floors. I take that off to hit the fine crevices. I bought this one and I absolutely love it. Gets under decorations between plants and in corners. The easy siphoning of fish debris used to be a pain to do. I did have to cut one of the tubes to make it a little shorter but that was easy. I gotta say tho that it's really powerful.

"Great hose."

I had to put the goldfish into the other 5-gallon tank, and then do the water change. It does the job I need it to,very effective. Gets under decorations between plants and in corners. I take that off to hit the fine crevices. I think this vacuum is a smart design by someone. It works great and was fairly inexpensive compared to other similar products. Almost a must have for anyone with an aquarium.

I gotta say tho that it's really powerful. Putting the thing together is really intuitive and easy. So after I received my replacement tool, i did a water change with it. Simple, lightweight design does exactly what it says it will do. I may still return this BUT I'm going to try once again. Once put together, I tried it immediately- it was AWESOME! I even separated the tubes and used it to clean my small 5 gallon!

"It has two connectors."

When I used it to get the water out, I found out it has pump function. Most of the time I just took out half tank then top off with fresh water. The shower mode make more oxygen just like an airstone. All it takes is a couple of pumps and the water starts flowing. I think this vacuum is a smart design by someone. Putting the thing together is really intuitive and easy. The speed of water removal works for cleaning an occupied tank.

"It has two connectors."

It's too small, just wash that baby out at the sink. The vacuum insn't too loud which is good, and has very good suction. This is definitely a better tool overall. They have plenty of suction to clean an inch or so off the ground. Gets under decorations between plants and in corners. I liked the idea of this product when I saw it, and decided to take a chance. Definitely not for the common colored gravel found at pet stores.

"Works so easily."

Now, the water change is a piece of cake. Water changing+ vacuuming, you can use it as powerhead to make more water movement. I really love this gravel cleaner for water changing and gravel cleaning. I just don't know why I didn’t order it sooner. I THINK most likely it came from the factory because it had a industrial smell to it. It is not good to let the goldfish encounter the cold water directly. That will show you which parts go were.

Thank you for making my job easier. I had a manual pump before that used suction pressure to suck out all the water.

Makes cleaning my daughter's turtle tank much, much easier. I even separated the tubes and used it to clean my small 5 gallon!

"It worked perfectly."

It quit working after the second use! Do what I did, and do, and so many others have stated in their reviews. Soft tubing, large debris basket, hand pump to get it to flow. - Multiple head attachment for different tasks. I pushed the tip down into the substrate and pulled the ditritus out right away. It's too small, just wash that baby out at the sink. The water gets going fast too so be careful lol thanks so much!

"This was perfect."

This one doesn't lose suction, and is easy to use. I have several divided tanks and I struggle to get the normal syphon in to clean. Once you get the tank water flowing out of the tubing. Hopefully my replacement works and I can change my review. I bought this one and I absolutely love it. Great product and would highly recommend!

"Oh my gosh!"

The item's weren't dirty or greasy or anything, but the smell was pretty strong. It is not good to let the goldfish encounter the cold water directly. I got this one until my son broke my siphon. The bucket clamp also doesn't work very well. Once you get the tank water flowing out of the tubing. And kind of shook it and tested it by plugging it in. I let everything soak in water and washed with safe dish soap before using.
