Product Description:

RGS is a root growth stimulant with sea kelp and humic acid is our primary bio-stimulant offering for use in lawns and landscapes. Formulated by John Perry of Greene County Fertilizer Co, RGS is the foundation of all Lawn Care Nut and Yard Mastery programs. 

If you are new to spraying liquids on your lawn, this is a great one to start with. It won't "burn" the lawn, or anything like that - and RGS is the best to start with anyway since it aids in soil health and stimulates roots in turf.

If you have challenges with your grass holding on during summer heat, getting RGS into the soil will help it through the stress. RGS is truly the backbone of the bio-stimulant program, hands down, and has the highest concentration of sea kelp hormones in the line. It was designed to increase rooting and decrease stress pressure caused by heat and drought. It will also feed microbial life in the soil which helps to optimize your fertilizer treatments.

"N-Ext" is the name of this line of products, and N-Ext stands for "Nitrogen Extension." RGS, Root Growth Stimulant, is kind of like the "base layer" of that line because it contains humic acid and sea kelp, the two primary bio-stimulants we recommend. The biologically active material contains humic acid and sea kelp to aid in initial spring green-up, buffer and extend nitrogen release rates, and add oxygen to the soil profile for greater nutrient uptake.

  • 1 Single Quart (32 oz) = covers up to 10,650 sq ft

Great little cleaner
Size: L50 Hybrid-renewed
I have a 2000 sqft condo with all stained concrete floors and this little vacuum does a great job. The set up in the app was very simple and the vacuum scanned the whole place and then got to cleaning. It takes it just under 2 hours to clean everywhere and then returns itself to the base for charging. The battery is at about 25% after the two hours. For $125 on Amazon Renewed, I can’t see how you could do better. I do empty the tray after each cleaning but that’s no big deal.

Run! Believe the bad reviews, they are shipping non-refurbished junk, no warranty or support!!
Size: L50 Hybrid-renewed
I have been a loyal Anker and especially Eufy devotee for at least a decade, I now have four levels to clean and have 6 Eufy's running! Well, I did. I got to #6 by purchasing this model, refurbished, I trusted in the Anker/Eufy brand that "Refurbished" really meant that, that it would be like new, and that while it only had a short warranty (3 months!), this would not really matter with Anker/Eufy quality and reliability. Unlike other companies in their neck of the woods, they have always taken pride in their brand and taking care of customers--I know this from personal experience. WRONG! The company is not what it used to be. This product is not "Refurbished, but like new" as I expected, and based on the many other reviews on here of people who just received used returned products. It seems Anker has reached a new low, and just try to harvest some profit off of returns by selling them to us on here. My L50 impressed me for exactly 3 months, and then started getting stuck, and stopping in the middle of the room without finishing. I should have returned it there and then, but I had no reason to distrust that the issue was resolvable, or Anker would take care of me. At 4-5 months it got worse, and wouldn't clean at all, and just bombed out saying laser error. I followed all the online debug steps (clean everything, make sure the laser turns and is clean/clear, factory reset, etc.). Same error. I set it aside as we got busy in the holidays. So, now, 6 months later, reaching out to customer service, get the door slammed in my face by the first responder ("Kelly"). Escalating, the second responder "Shane" helpfully sends me a link to their return policy, and "graciously" offers me about a $25 discount on new high end models costing $330-$690! Gee...thanks. So, leave me with a junk vacuum, and your "offer" is that I spend hundreds of dollars and trust you again?! No thanks! I guess my love affair with Eufy is over. No more will I recommend Eufy to all who will listen. I will certainly not be a customer in the future. They have "grown up", and think customers don't matter any more, we are just cash cows. Very sad...

AMAZING!
Size: L50 Hybrid-renewed
I love the ability to map out our house and have it clean while we are gone. This machine has a good battery life, rarely gets stuck and works very well overall. We will not live without one now!

Refurbished model parts missing, but Eufy/Anker fixed it.
Size: L50 Hybrid-renewed
I purchased a refurbished Robovac L50, and was excited to see if it was an improvement from my old 1s. Unfortunately the dust basket was missing a pin and that plastic screen that keeps the filter and foam in. I contacted the vendor, and Eufy responded quickly. The unit itself has laser guidance and a great app that lets you control it and set times, etc. It’s a definite evolution from the 1s. It is faster, cleans better, and allows you more ways to control it This is a great value for the money, especially for the refurbished price and the outstanding customer service.

Eufy beats the other guys in everything
Size: L60 Hybrid-renewed
We thought our old Eufy died so I ordered this since I always wanted the self-emptying model and the roller hair cutter was a big bonus since we have a chocolate lab that sheds a small bunny's worth of hair every day. Easy to set up, get added to the app, and just works. I will have to order more bags for the cleaning station, but overall very happy with this purchase even though the old Eufy started to work again right after this arrived.
