N-Ext Air-8™ Liquid Aeration is designed to create space in the soil, increase water penetration, and encourage deeper rooting to drive more oxygen into the topsoil profile.

  • One gallon covers up to 21,300 sq ft
  • Analysis is 0-0-5::N-P-K
  • Contains 8% Humic Acid
  • Great for hard compacted soil
  • Available in multiple sizes*

Product Description:
Air-8 Liquid Aeration dives down into the soil, breaking bonds between molecules, which creates space. Every bond that is broken creates more space (aka greater soil surface area) where grassroots can then spread and grow.

This also pulls down moisture and carbon since humic acid is included in the mix. If you have hard, compacted clay soil, Air-8 liquid lawn aeration is an excellent alternative to the butt-kicking you get from mechanical aeration.

One thing we know: 95% of homeowners cannot or will not rent a mechanical aeration machine. It's quite the hassle even to go and get it, especially if you don't have a truck to get it home in. On top of that, it's quite the workout. Since so many people are not able to mechanically aerate, liquid lawn aeration is your next best choice.

Now, we do still recommend mechanical aeration as a way to make a good seedbed if you are doing an overseeding. Poking all those holes really does help keep everything from washing away. Plus, running an aerator is a butt-kicking that everyone needs to experience at least once in their life! However, if you are not seeding, then just spray down Air-8, and you will get great results and never need to rent an aerator again.

It is a good idea to water the lawn the night before you apply and then again after your application, water it in with ½” of irrigation or rainfall. The more soil moisture present before and after application, the more effective liquid Air-8 will be.

Fit My Roborock Saros 10R Perfectly
Color: Saros 10R/Qrevo CurvX Accessories Kit
I got a Roborock Saros 10R for Christmas and purchased this accessory kit to have on hand when they are needed. I have an older model Roborock and you never know when something might need to be replaced. Since the accessories for my older Roborock do not fit my new 10R I wanted to ensure that I have dust bags on hand and don’t lose precious vacuum time waiting for delivery. After shopping around I decided that this set, for the price, made the most sense for me. Not only do I get the dust bags, but I also get replacement mop pads, main brushes, side bushes, filters and tools so when it’s time to replace those items, I’m ready. Although I don’t have a need to replace all of the parts just yet, I did check each of them to make sure that they fit and that the quality appears to be adequate. Everything fit well, and looks to be a reasonable replacement. There was some slight quality differences, however, there’s nothing that is concerning, and the quality difference is so slight that it’s barely noticeable. Considering the price difference from the name brand this accessory set is an excellent bargain!

Does not have everything shown
Color: Saros 10R/Qrevo CurvX Accessories Kit, Color: Saros 10R/Qrevo CurvX Accessories Kit
This kit does not have all the items shown. There are only 4 bags, not 6 as shown. There is only 1 red and 1 black roller, not 2 as shown. There is a screwdriver included but no directions. There is no odor to it and the items look durable but I have no idea how to replace the rollers and spinny things since there are no instructions. The bags fit my robot vacuum ok and are durable. There needs to be directions included as well as everything shown. Otherwise, you aren't getting your money's worth.

Solid Kit That Saves You Some Money
Color: Saros 10R/Qrevo CurvX Accessories Kit, Color: Saros 10R/Qrevo CurvX Accessories Kit
I ordered this accessories kit for my Roborock Saros 10R mostly because I didn’t feel like spending a ton just to keep up with teh normal maintenance. After using it for a bit, I can say it’s been doing exactly what I hoped it would. First thing you notice is the cost of course, keeping these robot vacuums running can add up fast, and this kit really helps take the sting out of replacing the usual wear parts. Most of the pieces line up with the Saros 10R really well. Everything went in without a fight and once installed, it all works the way it should. Brushes rotate fine, filters sit where they’re supposed to, and nothing feels janky or poorly sized. Quality wise, it’s pretty close to the name brand stuff. You can tell there’s a small difference if you really look for it on some parts. Some of the plastic feels a bit lighter and a couple items don’t have that same premium feel. But in use, I’m not seeing much of a difference, cleaning performance is still strong and the vacuum hasn’t skipped a beat. Durability is the one thing you can’t fully judge right away. So far though, everything seems to be holding up nicely. No fraying, cracking, or early wear, so I’m cautiously optimistic they’ll last about as long as the originls. Overall, this kit is a good deal for the money. It does what it’s suposed to, saves you some cash, and keeps the Saros 10R running smoothly. Not perfect, but definitely worth it. Four stars.

most can fit saros 10, but not all
Color: Saros 10R/Qrevo CurvX Accessories Kit, Color: Saros 10R/Qrevo CurvX Accessories Kit
I should have done a little more research with these. I purchased this for a Saros 10, i thought the Saros 10 and 10R was basically the same besides the filters. I was wrong. Although the brushes are the same size, they didnt fit. They lacked a special metal piece on one side, and the 10R has a different shape on the other, cant even jerry rig it to fit. The filters didnt fit my Saros 10, but that didnt cause the dropped rating, but they quality of it looks very good, and seems well made. The side brushes are good and they fit my Saros 10, replaced them and didnt have a problem. The bags also fit and they are very good. The mopping brushes did not fit, but it was very well made and definitely wasnt just a cheap set. The brush and screw driver were just to add additional number counts and basically useless.
