GOOBAT Rechargeable Automatic Aquarium Gravel Vacuum Cleaner, Sludge Extractor and Water Changer 2 in 1 Fish Tank Vacuum for Aquarium Water Height Up to 30-Inch

I brought one that was made by Eheim and got sick of them not working after about 6-8 months of use, I was on my third purchase and my husband recommended I find another company. Well this one came up from my search and I have been using it for months not and I could not be happier, the fact that its chargeable and can be submerged with no issues makes all the better product to use. I have a 125 gallon tank and a 75 gallon tank in my home and this is a true time saver.

Worked great the first time, for about 2 minutes, and then water started spraying out of the charger port. Had horrible suction, and could particularly just floated around in the clear section. Did not have any extensions connected to it. Followed all instructions and did not have it fully submerged. Dried the unit out, tried to use it again and it failed to turn back on. The water seal on the battery section is absolute crap. Would not recommend this product to anyone. It’s a knock off, and the model you get is not even goobat, it’s a sun sun Chinese knock off. Very disappointed. Returned and bought the eheim version, which was much better.

Didn't work well for gravel. Company was very understanding and solved the problem for me.

This does not work at all after a while & It’s a complete gimmick. It actually just makes the algae finer and spits it back into tank. There a small amount that builds up on the device that makes you think you’re removing crap from the tank but it’s worse. My fish started dying after a short time of buying this. Don’t waste your time or money & stick to the regular siphoning routine until they come up with something better in the future.

It worked just fine for me. You just have to be patient with it, as it's not a high-powered vacuum.

Pretty good tank cleaner, you do have to let the water settle back down after cleaning.

works great but battery is not water proof

Used it once and it was amazing. Went to use it again and it won’t charge. I took the top off to look at the battery compartment and see if I could fix it. Nothing seems to be wrong. I feel like I wasted my money.

Most aquarium vacs are absolutely useless, intrusive, underpowered, ineffective. This is not. It works. It shifts the sludge and fills a bucket in a few minutes, or recirculated through its own filter and cleans the suspended waste from water. It runs for many sessions from a single charge. It's the best aquarium vac ever, and if we had been able to get this 30 years ago when we had a big marine aquarium, we'd probably STILL have a big marine aquarium...

delivered without charger and charging cable. Really dissapointing
