GOOBAT Rechargeable Aquarium Gravel Cleaner and Sludge Extractor, Automatic Aquarium Cleaner Vaccum for Medium and Large Fish Tanks

Live this product. After having a battery operated gravel cleaner before that would very quickly lose full suction, this is amazing. You can see the sludge shooting up the tube and it is very solid, whereas my old one kept coming apart.The only reason for four stars instead of five is that the mesh isn’t quite fine enough so some very fine silt does come back out through the mesh and clouds the water for a while.Even so am totally obsessed and instead of it being a chore the clean the gravel I am giving it a quick once over most nights with this as is so easy.

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...

Waste of money. The product pumps okay but the filter is useless as simply discharges all the fish poo back into the water due tot he filter not being fine enough. Unless a finer filter is added (which the manufacturer has confirmed to me they don't have) the product is useless - you would be as well using a siphon you can buy for a couple fo pounds. Oh, and it is not a GOOBAT product, manufacturer is SUNSUN (Chinese, I think)

delivered without charger and charging cable. Really dissapointing
