LONDAFISH Electric Fish Tank Vacuum Cleaner: Syphon-Operated Gravel, Water, and Sand Filter Washer

Rob: The first time using it it worked ok parts kept coming undone witch made it challenging. The second time had a hard time getting it to turn on with the batteries,than plugged it in gave a few taps and it started. The third time won't start
Don't waist your money it's c***.

Tessa Greenwood: It works but the angle at which you have to have it in the water to meet the minimum water level line does not allow for easy access. My tanks is tall and narrow but when the water is more shallow (cleaning in between moving fish etc) it is nearly impossible to get this thing to work. (TLDR only works with full tank/deep water).

Amazon Customer: I at first thought it was a piece of junk and started a return. I couldn’t get it to produce suction. Turns out there was a spare short tube section in the larger diameter pick up tube that connects to the pump that was preventing a full seal. Took me a few minutes to get it out but once I did it works great! I do notice that it randomly will stop pumping. Just flip it off and on quickly and it will start back up again. also make sure you stop using it before the bag is to full or it will pop off and suck up clean water from the tank before removing otherwise you distribute waist throughout the tank. Overall good product for the price!!

Alex: This is really a very average product. So hard to get just the right height in the aquarium water level to actually work, supper frustrating. In the end i gave up using it and bought a FLUVAL that has worked perfectly from day 1.

CrystalodowdCrystalodowd: Well I was so excited to receive this, thinking it was going to make my axolotl tank so much easier to clean but it didn’t. It was basically a waste of money and time. Now I need to go out of my way to return rbis stupid thing. It literally worked for two seconds and died. Sounded like it burnt out. So I let it sit a few minutes and then it works again for a few minutes then did it again. Burnt out. Very stupidly how it’s made. It says on the pole ( I attached pics ) tbat the water must be a min of here, but at the same time max here also .. at the very same spot is the mini yams maximum basically. WTF! How is tbat even possible. Uou have to basically how the filter part in the water fir it to work , but you can’t have the water go any further tbat that little line at the same time (the min/max line) so how are you supposed to be able to move around to clean. Because it also only seems to do anything if you tilt it sideways. If you have it straight up and down it does nothing and even then when it does it barely sucked up an old blood worm for that. Suction sucks. Wish I’d invested a few more bucks in a decent one tbat I wouldn’t have to waste my...

shoester: It is great that when you suck up the stuff on the bottom, that it goes into that little bag that hangs on the side, you must maintain keeping this below water level. Once you figure out how to put it together, it is great. I went through two of these until I figured it out, as I destroyed the first one. It needs more instruction on how to put it together accurately.

John L.: Wish tubing was longer. It’s great for gravel vacuuming because the outlet isn’t facing upwards like others on the market but that’s also a con for smaller tanks since it requires more room for the tubing since it doesn’t bend upwards. The wall adapter is a really nice addition, no more batteries to buy!

I had plans to add a siphoning pump on the end so I can pump water through to get the flow started and use the motor to accelerate the flow, but this didn’t work out because there are another set of holes on the top to release water build up inside the device. All the siphone pump did was suck air through those holes so in the end you needed to submerge the impeller anyways.

NOT DISAPPOINTED! 😍 I have a live-planted 60 gallon Cichlid/Semi-Aggressive fresh water tank no where near access to a water spigot for traditional water changes with those high priced gravel vacuums.. This little thing cleaned up all the fish crap from my gravel easily! Easy to assemble, filter bags are washable and reusable!

I'm legit leaving this at 5 stars even though I have some very very small complaints that are more annoyances than anything: 1) the unit will come apart at the pipe attachments if you're too vigorous.. Which breaks suction and makes you have to reassemble it.. and get wet..eee. 😂 2) Filter bags get full FAST if you have a big tank! Be prepared to change them or clean them many times if you have a large tank or... goldfish lol. 3) The gravel cup at the end gets bigger rocks stuck in it constantly. Don't think the slats need to be that wide?

If you need something inexpensive to get your gravel clean of poop in a tank in a crazy location.. this is awesome!! The pump is powerful, the power cord is long, and you can use the battery option...
