Best Pond Vacuum

Keeping your pond clean can feel like a full time job at times. If you want to fully enjoy your pond then you are going to need it looking at its best, but this can take hours of scooping, scraping and sifting, when really all you want to do is enjoy time in your garden! Not only that, but a pond that is full of debris and algae is actually going to be quite harmful to the wildlife that is living in it, which can affect the lifespan of your fish! 

If you are wanting to keep your pond clean and healthy then there are various ways this can be achieved….with particular species of fish, with strong filters, or by cleaning (with the latter by far being the most effective). The best way to clean your pond effectively is by using a pond vacuum. These clever machines are designed to suck up and filter out dirt and debris from your pond, leaving it spotlessly clean in a fraction of the time that it would take cleaning manually! 

A pond vacuum is essentially what the name suggests – a vacuum for your pond! It sucks water in through a suction pipe into a tank with filters that then clean away the debris and dirt from the water and send it back into your pond again. This continuous process saves you from having to drain your pond to clean it, so your plants and fish will be unharmed in the cleaning process – plus you will be a lot less stressed at the end of it all! 

If this sounds like just what you need, then keep reading to find out about some of the best pond vacuums we have found, along with the key features you need to look out for when purchasing the best pond vacuum.

In A Hurry?

If you are sick of spending hours cleaning your pond, or maybe you are fed up with never being able to achieve that “perfect” clean of your pond then look no further! We understand that you don’t want to waste any more time so we have included all of the essential information that you need to buy the best pond vacuum. 

Manual or Electric? 

The two main types of pond vacuum that you will find are electric and manual models. There are pros and cons to both so it is important to think carefully about which is going to work for you. 

A manual pond vacuum is going to work using a hand-pump that you have to force up and down to create a pressure which will then suction the water up into the tank. Thanks to the lack of need for electric motors or other parts you are going to find these to be considerably cheaper to purchase and also to run, but it is important to remember that this is because of the amount of work that you are going to have to put into using them. Admittedly, they are going to be easier to use than nets etc but you are still going to have to put in a lot of effort to use them. However, they do have the added benefit of being incredibly light and portable in relation to their electric counterparts. 

Electric pond vacuums are going to be your more expensive but less laborious option. Mains powered, they will use an electric motor to suction water up into the tank and then back down into your pond once it has been cleaned. Thanks to the mains powered motor you will find them to be very quick and easy to use, with a fantastic cleaning rate. The one real downside is the fact that you are going to have to consider how close you are to an electricity source thanks to the cable (plus they are also quite a bit heavier). We found a lot of cables to be around 10m in length so this should be more than long enough for most average sized gardens! 

Single or Double Chamber 

Pond vacuums are going to come with one or two chambers depending on the model style that you are looking at! A single chamber model is going to be your cheaper option and these tend to be found on manual pond vacuums. They work by suctioning the dirty water into the one single chamber, cleaning it and then sending it back down the outlet pipe into the pond. There is nothing WRONG with this process – it works perfectly well – but because you will keep having to stop to allow for a tank full of water to clean and be emptied, you are going to find that single chamber models will take longer to get the job done. 

A double chamber pond vacuum is going to work slightly differently. These suction the water into one chamber, the same as the single models, but then they transfer it into a second chamber as part of the cleaning process for it to be emptied back into the pond. This leads to a more cyclical process of water continually (more or less) being collected and then sent back into the pond again. This will not only allow you to get the job done faster, but you also tend to find that your water will be cleaner afterwards! 

Suction Depth and Hose Length 

It would be fair to assume that the length of hose that comes with your pond vacuum is going to be what you need to check to see if you are going to be able to clean the bottom of your pond – but unfortunately there is actually a lot more to it than just that! 

Of course, the first thing worth checking for is your hose length, as if this isn’t going to reach to the bottom of your pond then you don’t stand much chance of being able to suction/scrape the algae and built up debris from the base of your bond. Hose lengths range from around 12ft up to 30ft – we would always recommend looking for a hose length that is longer than the base of your pond, this will make it much easier for you to reach all areas of your pond without having to move as much! 

BUT, you will often find that the maximum suction depth is actually less than the hose length! The suction depth is the depth that your hose will be able to suction at. A pond vacuum that isn’t powerful enough will struggle to suction at depths deeper than 10ft (some as little as 6ft), meaning that it doesn’t matter if your hose length is way over this, if you pond is deeper than the suction depth – you won’t be cleaning the base of your pond! We found suction depths ranged between 6ft and 20ft depending on the wattage and power of the pond vacuum. 

TOP TIP: The best way to find a powerful pond vacuum that is going to work in the deep, dark depths of your pond…compare the suction depth, power and the flow rate. All of these features together will determine the depths that you can work to and how quickly you are going to be able to clean your pond! Anything over 1100W and a depth of 12ft is going to be more than enough for most small/medium sized ponds.

Additional Pond Vacuum Features 

We have looked in detail at the main features that you need to consider before purchasing your pond vacuum, but there are still going to be a wide variety to choose between. Here are some of the features that we loved in the best pond vacuums to help you sift out the best from the rest! 

  • Weight – You are going to be moving your pond vacuum around your garden so it is definitely worth considering how heavy they are going to be. Most models range between around 14kg up to 37kg! 
  • Portability – Whilst we are discussing the weight of your pond vacuum, you also need to check how easy it is going to be to move it from wherever it is stored to your pond. Most standard vacuums come on wheels but this isn’t always the case with pond vacuums so this is definitely worth checking for! Make sure that they are large, strong wheels ideally with brakes (especially for sloping gardens). You also want to look at the quality and positions of any handles in case you are having to lift your pond vacuum into position! 
  • Adjustable suction – If you are wanting to protect the wildlife and fish in your pond then definitely opt for a model with adjustable suction rates. This will allow you to adapt the suction rate to suit both you, your pond and your fish so that you can work more slowly around more delicate areas of your pond.
  • Discharge hose – Your discharge hose is going to need to be long enough to stay IN your pond as you move around suctioning with your suctioning hose. They range in lengths between around 6ft up to 30ft. We definitely think the longer the better as you don’t want to turn around to see your pond water all over your garden!
  • Cool down rate – Many electric pond vacuums are going to have to cool down periodically during the clean. This is essential to avoid your machine overheating and becoming damaged. For some pond vacuums this will be as short as 3 minutes but for others this could be up to 10 minutes which is obviously going to impact quite massively on the amount of time it takes to clean your pond! 
  • Economical – Pond vacuums aren’t going to be the cheapest of machines to run so if running costs are important to you then make sure to check for pond vacuums that are designed to be more economically run. This will probably involve opting for a less wattage and only going for what you actually need! 
  • Attachments and Nozzles – We would recommend checking the different attachments and nozzles that come with your pond vacuum as these are going to dictate the quality of job that you are going to be able to achieve! You will need AT LEAST a wide suction nozzle for the majority of the pond and a scrubbing head to remove algae that has stuck to the sides or base of your pond! 
  • Build Materials – Most pond vacuums are going to have suction pipes that are made out of plastic. However, some of the best pond vacuums will have pipes that are made out of aluminium which is going to be much more durable and long lasting! Pipes with transparent sections are going to make it much easier for you to see how well your pond vacuum is working!

Frequently Asked Questions 

What guarantee will I get with a pond vacuum?

The guarantee with your pond vacuum often depends on whether you opt for an electric or a manual model. Manual models tend to have around a 12 month warranty, whereas electric models can have up to a 4 or even 5 year warranty! It is important to check what this covers as for many the filter and pipework won’t be included! 

Do I have to replace the filter in my pond vacuum?

Yes! You are periodically going to have to clean and even replace the filter in your pond vacuum. We would recommend emptying and cleaning your filter after every use (if your pond is particularly dirty you may even have to clean it during a cycle round your pond!). Every few cleans you will need to replace your filter as using an old, clogged filter will not only affect the quality of the clean but also could damage and strain the machine. 

Is it safe to use a pond vacuum with fish? 

Many pond vacuum manufacturers will advise that it is safe to use your pond vacuum with fish – however we would recommend that this should only be done with extreme caution! Check the size of the suction nozzle on your suction hose and the power of the suction to make sure that this is not going to harm any of your fish. Also, be mindful of the fact that such a thorough clean of your pond is inevitably going to impact on the pH rating of your water which could upset more sensitive fish!
