Product Description

Poolpure focuses on bringing great technologies and products to the market that truly provide the cleanest water filtration possible for the health, safety and happiness of every pool and spa owner.

How to find a replacement cartridge for your pool or spa?

If you already know your filter cartridge's part number or the replacement number, you can use the search the part number on our product page to quickly confirm whether the filter is compatible.

If you do not know the replacement part number for your cartridge, then choosing the right cartridge can be accomplished by measuring your existing one. Use the following steps as a guide:

1. Measure the outside diameter of the cartridge in inches (+/- 1/16th inch)

2. Measure cartridge length from end cap to end cap (+/- 1/16th inch). Exclude any handles or extensions.

3. Identify the correct top and bottom type. If the top and/or bottom is open, measure the inside diameter of the opening (+/- 1/16th inch). If the end cap is closed make note of its identifying features.

4. Make note of the manufacturer and model number of the filter into which the replacement cartridge will be installed.

5. Take note whether or not there is a center core (PVC pipe in center).

The media could not be loaded.

I brought this thinking it would be a bit of a punt (wasn’t sure it was going to be a good buy) but it was… I had winterised the pool (21ft circular above ground pool) I didn’t put a cover on it over the autumn or winter (don’t judge) and there are number of trees where the leaves had fallen in.

The pool was thick green water the sides covered in algae, it was so nasty I was apprehensive to put my hand in 😬. I brushed down the sides, added shock and started to pump through the water. (I have a good polysphere ball filled pump)

I tied a bit of fishing wire to my floating thermometer and to the handle of the robot just over the depth of pool and let it loose… (I had to tie the float as you couldn’t see more than 2 inches below the surface. ) and off it went!

I am rubbish pool owner, my pool doesn’t have a perfectly flat bottom, it has an adequately flat surface with few small dips and rises. But I watched the float diligently traveled around my pool. When it stopped (I think after an hour or two) and the cycle was complete I pulled it out.

First point to note when the bottom is dirty lift it out level ( it quite heavy feels about 6 or 7 kg although could be wrong/lighter) otherwise the muck will come out (note this isn’t an really an issue when it’s just picking up sand and not much big stuff) once I got it out it was full of worms, leaves and muck,I was surprised by the size of the leaves.

Second point to note, it takes FOREVER to charge. I’m not sure exactly as I haven’t timed it but in any day I could only use it twice, once in the morning after it had charged over night and then in the afternoon after it had been charging all day, it wasn’t an issue but it’s not quick at all , “hours and hours”

Anyway long and short by the time I could actually see the bottom of the pool it was spotless. I used no other cleaning method, I only brushed the sides of the pool never the floor, so the robot did a great job, I was honestly surprised but I would say it exceeded my expectations. It did exactly what you would want from a pool vacuum.

Other than the effort of dropping it the pool; retrieving it; washing it out; charging and repeating it was no effort.

My pool is chystal clear, I put it in every day or so even though it doesn’t need it and it’s always got stuff in it. So far I have nothing but praise… I love it proper game changer (for translation I mean this is going to be so much easier than using a conventional vacuum for the rest of the season)

Note with the video (sadly only able to add one) but my very uneven pool floor is the reason for robot wheelies in the video, on flatter parts of the pool it’s rides perfectly smoothly but I guess it just shows it can do a little off roading too! 🤭

I’m hopeful it will have longevity, I’ve had it now for almost a month and have pretty much used it daily, sometimes twice so I would guess for 40 + cycles and no issues… yet 🫣

It works and does what it’s supposed to do. However don’t expect it to pick up debris from every corner. Although initially it will go “uphill”, after 1 hour it tires do so. Sometimes for some reason it can get “stuck” against a wall and needs “help” by moving it slightly, but apart from all that, yes I would recommend it but not for a pool larger than 8 x 4. Yes it runs for 120 minutes and does take 3 hours to charge. As said, it’s good product for the price.

I bought this to replace one I had from Amazon 4 years ago. Not really happy with it truthfully. I am seriously thinking of returning. It just doesn’t do the job! Y old one was brilliant till the battery died. This one is fast but stirs up dust and debris rather than vacuuming. Plus I struggle to turn it on. My old one which I can’t see a name on it was absolutely brilliant. I’ve tried the new one today and ended up manually vacuuming the pool, it’s an inground pool. This new one was more expensive but no where near as good. Very hard to press the on button to get it to work.
