WORKS GREAT S AND THE STREAM OF WATER HAS AWESOME WATER PREASURE!!!This is a great addition to the Filter Floss cleaning tool, however I wouldn't buy it alone. I purchased the Filter Floss as the primary cleaning tool which is more powerful and cleans the Spa filter from the outside, which is how I start the cleaning process. The Power Pic compliments the cleaning process by cleaning from the inside of the filter and loosening debris stuck deep in the filter crevices, and follow up once more with the Filter Floss for an awesome clean.Set up a way to put my filter horizontally and held flosser underneath slightly off-center so it would spin around with the force of the water. I then slid it back and forth underneath it go get the full length of the pleats, then additionally turned it vertically to the filter and went from end to end. Result was perfectly cleaned pleats even at the ends! My hot tub filter has plastic with holes on the inside so could only rinse from the outside so was fantastic result! I also have a solid end so I had to put the pvc pipe at an upward incline so it would not spin off the end of the pipe while spinning. I had a frame with two wire shelves with square holes turned vertically so I could have it inclined on the pipe. Highly recommend getting one to save time and water!If you're into gadgets that not a lot of people have, this is cool. Otherwise, it's just so so in my book. Unless you have a bunch of grass or bugs going through your tub and into your filter a regular jetted hose nosel will work for cleaning out hot tub filters. It doesn't really push anything out of the filter from the inside. A regular jetted hose nosel works fine from the outside of the filter just as well or better. Not really impressed.This Power Pic is nicely made and has great water pressure. Because my pool filters have small holes on the inside, this didn’t work for me. I will keep the Power Pic for other cleaning jobs.I use the Filter Flosser from the same manufacturer to clean my pool filters quickly.Works great, just wish it had a shut-off to it.Not that powerful, but really don't want too powerful on filters, it would open holes up in the paper.Overall great quality product. I think the idea is to use it in conjunction with other tools from the same brand but i use it as a standalone device. Tool is well made. I gave it 4 stars because it was missing or did not include a washer - not a big deal it was probably lost in shipping and because there was no shut off valve on the device. I bought one at Home Depot for about $4 and the tool works like a champ.GoodSomewhat pricey -- considering less to buy " Filter Flosser ", which includes handle forthis extension's operation -- but, it does a good cleaning from inside a filter.
