Product Description

aquarium gravel cleaner
aquarium vacuum

Effective Filtration

The filter effectively cleans impurities and waste in the water to keep your aquarium clean.

aquarium vacuum

Upgrade Suction System

Advanced suction power is specifically designed to pick up dirt particles, remove waste and extract sludge.

Instructions for use:

  1. Not recommended for fine sand or fine gravel.
  2. You may see there are some water drops on this device when you unpackage it because every unit was tested in water to confirm they could work properly before delivery.
  3. Depending on the aquarium depth, you can add the extension tube or extension nozzle. The extension tube is adjustable.
  4. Before starting the cleaner, please make sure the motor is fully submerged in the water.
  5. Move the cleaner gently back and forth along the bottom of the aquarium.
  6. If the impeller of the pump is blocked by debris, loosen the impeller nut counterclockwise, remove the pump cover and clean the internal debris.
  7. It is recommended to shake the gravel cleaner up and down during the cleaning process so that the cover can drive the dirt on the gravel more effectively and absorb the gravel better.

73 customers mention41 positive32 negative

Customers are mixed about the value of the cleaning agent. Some mention it's worth the money, works well for the money and is considerably better than the cheap ones. However, others say that it'll never start, has cheap construction for the price and doesn't last very long. The hose provided with the unit is of poor quality and is too short.

"...This vacuum is great! For less than $30, it's a great value...." Read more

"...For that reason, the price is a bit high...." Read more

45 customers mention13 positive32 negative

Customers are dissatisfied with the filtering of the cleaning agent. They mention that the filter clogs up fast, the motor gets clogged, and the filter element blocks somewhat quickly. Some say that the hose comes pinched off and it's hard to keep the flow going. Overall, some customers feel that the product is not suitable for catching all debris.

"...fine sludge from being discharged back into the tank, the filter screen is inadequate to clearing the water enough to return to the tank..." Read more

"...The motor being clogged is the biggest issue I've been running into every time I do a water change for the past half a year, and now it finally..." Read more

"...This vac is also amazing as a no-mess siphon, which is another useful feature." Read more

"Works well for the money. It gets clogged pretty easily so I have to clean it out often but way faster for doing large water changes on huge tanks...." Read more

Not as good as expected.
2 Stars
Not as good as expected.
The suction is insufficient to pull snail shell fragments into the filter, nor is it sufficient for easy use in a gravel bottomed tank; the filter chamber is difficult to remove and the top and bottom difficult to remove for cleaning. Some protuberances to allow better grip would help. The filter element nearly impossible to remove for me with the arthritic fingers. The filter screen is plagued with pinholes, as pressure builds when the filter gets plugged, small streams of dirty water shoot all around and I've been unable to remove the screens from the housing for replacement. When digging into the gravel with the suction tube and sludge filled water enters the filter chamber, the filter screen does not stop the fine sludge from being discharged back into the tank, the filter screen is inadequate to clearing the water enough to return to the tank necessitating use of the kinked discharge hose and removing the contaminated water rather than filtering and reusing it. The discharge hose was not coiled but folded resulting in kinks that I've been unable to remove even with heating and stretching, restricting discharge flow.

I highly recommend this product for anyone who is into axolotls or fish. It will definitely help keep the tank clean and do water changes smoothly with ease and great results!

1.0 out of 5 stars Missing parts, worked once only to sort of clean gravel wouldn't remove water
Reviewed in the United States on June 4, 2019
Size: 1 Count (Pack of 1)Verified Purchase
I will be returning this gravel cleaner for so many reasons. 1. It is missing part 3 - this is the one where you allow it to remove the water from you tank - I still sort of rigged it to work and got one bucketful after AGES - but then it just quit working so I think part 3 must be pretty important (I think it holds the hose steady). 2. I was very unhappy with the suction power of the thing - it would siphon up my moss balls and a ton of my substrate, leaving the debris behind. Spent well over 1 hour trying to get it to remove debris (and I had just cleaned the water the week before so it wasn't that durty. 3. Just like nearly ALL these tank cleaners the head of the siphon is too big unless you have a 100 gallon tank with things spaced miles apart, You just can't manipute this very long unit to get in the right place. 4. After trying and failing to make the water removal work, I went back to try to do some more cleaning of the gravel and it started to work the suction just stopped even though the motor was still running. Trying to use the whole thing was a miserable time wasting experience - guess I'll have to keep using my unwieldly Python - at least there is no electric motor to break down. When it arrived, it kind of looked like the box had been used before, nothing sealing the inside bag, missing part, electrical cord just kind of loosely wound.

4.0 out of 5 stars Finicky but with patience does what I need it to do
Reviewed in the United States on January 30, 2023
Size: 1 Count (Pack of 1)Verified Purchase
Trying to clean the sludge in the rocks has always been difficult. By the time a small area is clean it's time to refill the water. I gave this a try. It works okay, but it took several hours to get to the whole tank, because I kept waiting for the fine sediment to settle/filter through my canister. What does settle coats everything, requiring another pass. It works, but takes patience. The suction is okay, but honestly any greater suction and more of the finer gravel will get sucked into the motor.

The bad: As expected, you have to stop and clean the filter a lot. I don't think there is a way around it. Worse, though, the unit just hums sometimes when you turn it on. You have to remove the plastic collar and manually spin the rotating fin, reassemble then try again. This is clearly a quality issue, and I'm sure in the near future it just won't spin anymore. For that reason, the price is a bit high.

Bottom line is it does what I need it to do, but the poor build quality will result in it not lasting long.

The media could not be loaded.
 I've got a betta tank I've had for a few years. I have used up to this point a small squeeze suction thing for water changes, that can pull some stuff off the surface of the stones, but doesn't do much for under the stones. I wanted to finally get a good cleaning. Since this is just an 8.8 gallon tank, even a normal gravel cleaner, I'd run out of water before I got almost anything done.

I didn't know there were ones like this that recirculated the water back in, allowing you to clean fully without dropping the water level, so I got this and tried it this morning.

And LOVED it. Totally and completely.

First, my advice - start at the back edge of the tank, since as the water clouds, it'll be harder to see. I started at the front so before I hit the half way point it was already too cloudy to finish easily that far. Had I started at the back, the cloudy water wouldn't have mattered.

Cord is more than long enough, and it has an extension for even deeper tanks. I was worried the water would come out under pressure, since this wouldn't submerge in my shallow tank, but it doesn't, it just trickles out as you can see in my video.

It does an awesome job - I was amazed at what I saw it pulling out from around and under the gravel, that my normal siphon couldn't hit. I do testing of all sorts of levels every month or so, and can't believe my numbers have been as good as they've been with all this gunk hiding under the gravel.

This should be something EVERY aquarium owner has. I'll start doing this every month or two when I'm doing weekly water changes.

Filter also has a cartridge that you can reverse to use as a suction device, but I can keep using the one I always use for that during water changes, I don't need this function, but it would be handy for people with larger tanks or who can't rely solely on gravity and siphoning.

This is a great gravel cleaner, it gets the job done. I have gotten multiple of these because I seem to loose the parts multiple times. This time it seems like the suction power isn't strong enough to suck all of the dirt from my gravel, or that it takes a super long time. I still will stick with this brand because the water change feature is AMAZING and so much easier to use than a regular siphon. The water also squirts out of the filter changer which is sometimes dirty water, it gets the job done with the main debris but maybe not so good with the dirty water itself. It did however get my 75 gal fish tank to be a little clearer than it was. Overall it has its ups and downs.

Ayant possédé celui d'une marque bien connue, je peux dire que celui-ci est mieux pour 2 fois moins cher. Fonctionne sans piles, étanche, les plastiques semblent de bonne qualité, la grille a l'air solide et l'aspiration est bien dosée pour ne pas aspirer le sable 1 - 2mm. Evidement l'eau se trouble plus ou moins pendant l'opération mais c'est normal pour ce genre d'appareil.
Point important : ce n'est pas indiqué dans la notice mais il est impératif de nettoyer TOUT le circuit d'eau avec le jet d'un robinet après chaque utilisation, sinon le débit chute fortement car les débris végétaux ont tendance à colmater le conduit.
Un regret, il faudrait un accessoire pour pouvoir aspirer les recoins, la cloche étant assez volumineuse.
La notice est imprimée sur un papier glacé de qualité, on a plus l'habitude.

5.0 out of 5 stars It works very,very well provided water level is adequate
Reviewed in Canada on May 1, 2019
Size: 1 Count (Pack of 1)Verified Purchase
This is one handy little unit, so glad I purchased for turtle tank maintenance. I cannot speak for gravel filtering ability as I don't use it for that but it is excellent for sucking dung & chunks of shed turtle shell at the bottom and using to empty/refill for water changes. I put a tall flower vase on the floor next to the tank to store this in, works great and keeps it handy for use whenever I need it!

At first I was disappointed thought it didn't have all that great a suction power but the problem was the water level. It needs to cover the vents at the base of the unit or it cannot suck like it should and will gurgle with too much air. Get it under the water and wow, picks right up! Can't recall if description says gph on its suction ability but it hums right along with plenty of power for the job during water changes. I added photos, the one showing the black section above the suction tube with holes mid-way...those are the holes that need to be under water level for good suction.

It is a tall unit, not meant for small tanks, best with deeper tanks. Mine is 21 inches deep, filled to about 14 or 15 inches and I think that is about as shallow as I can get away with and have this unit work. Actually I can go lower by removing the extension from the tube end, I believe I mentioned minimum levels answering a question on this product so you can review those if need the info. You can angle it to ensure the vents are under water level, but only to a point. All the pieces are removable as well so you can vary the height up & down with the gravel filter extensions or the water suction tube.

The filters that attach to the unit are easy to change out and of fine mesh so they trap the most minute particles. Changing the cap on them is all that is required to switch from suctioning crud from tank bottom to sucking water for water changes. The different cap has the hose end in place & directs the water flow straight to the included hose for water changes rather than filtering it. Again, suction is directly affected by water level and it works fantastic provided water is adequate level but fizzles right down to nothing if not.

The included hose itself is crimped from too long in the same position in packaging I assume. Still works but 3-4 major crimps present, it is a good diameter for water changes forgot to check exactly what diameter it is I'm guessing 1/2 inch ID.

The electrical cord is also of adequate length, not too short or too long.

Overall, very good value found in purchasing this unit. Glad I chose this one over all that were available!

Reçu et testé immédiatement.

Au déballage, on peut voir qu'il y a deux façons de le faire fonctionner. Le mode change selon l'embout qu'on place sur le filtre. Celui avec téton permet de connecter le tuyau et donc de vidanger l'eau alors que celui sans téton permet de nettoyer le gravier sans vider l'eau.

J'ai d'abord testé le mode nettoyage sans vidange. Bonne aspiration et bon résultat.

Pour le mode nettoyage avec vidange, j'ai placé le tuyau fourni avec et c'est la que le bas blesse. Le tuyau est bcp trop souple il se "coude" constamment à plusieurs endroits et du coup l'aspiration est fortement ralentie. Obliger de surveiller et de défaire les nombreux coudes en permanence.

Je vais remplacer ce tuyau par un plus long et plus ferme.

Pour le reste, rien à dire. Le nettoyage et changement d'eau de l'aquarium (400L) est vraiment simplifié. Les différents tubes prolongateur me permettent d'arriver sans aucun problème au fond de l'aquarium.

Je recommande cet appareil mais penser à remplacer le tuyau d'origine pour profiter pleinement de la puissance de la pompe.
