What Customers Are Saying

Customers overwhelmingly praise this self-propelled mower for its powerful 80V motor, exceptional battery efficiency, and ease of use. Most report covering large yards on single or dual charges, with many noting performance matching or exceeding gas models. The self-propelled feature significantly reduces physical effort, and reviewers highlight smooth speed adjustment, quiet operation, and sturdy metal construction. Battery life exceeds expectations with quick two-hour charging. The turbo feature handles thick grass effectively. A few users report minor disengagement lag when backing up and occasional thumb control fatigue, but these issues are rare compared to widespread satisfaction.

Does a great job for my small lawn

Would Recommend

Like the title says. I have about 1/4 acre and the mower tackles it with no problem. I have some slope to the yard so the self propel is useful, but it’s not needed on flat ground. It can sense when it’s going over thick grass and boosts the power to get thru it. Never going back to gas power!

Mower works great battery charger is trash

Would Not Recommend

Mower is great for the most part although the self propelled did not work. The mower is pretty heavy and I couldn’t get it exchanged because I couldn’t load it back in my car my self. As well as I didn’t have help. Also came pre scratched. Another thing is the battery charger literally only lasted 1 year and 2 days. It sits on my bench in the garage unplugged until I need it and usually I get 3 mows out of 1 battery and then I charge it Don’t recommend

Would never buy again

Would Not Recommend

I bought this lawnmower in May 2026 to cut my .19 acre yard. I’ve had nothing but problems since I got it. I have it set at the second to highest setting for the height of a grass. When I’m mowing, it gets bogged down and the blade stops. Sometimes when I’m bagging it, the bagger will work and then it won’t work and the grass just gets stuck inside the lawnmower deck.. I changed the blade and it still cuts poorly. I usually push it and don’t even use the automatic because It can’t keep up cuttin...

Not Good

Would Not Recommend

1st 2 mows it worked great, only used half the battery. Now I cant mow on single charge, it only does 1/2 the yard. Boggs down in medium to thick grass. Also mows uneven. Kobalt mowers are not very good. Will be returning this one also. Have tried 2 other models and same issues. Stay away from kobalt mowers

Weak battery

Would Not Recommend

Brand new first time it cut our .25 acre lot with about half battery life to spare. Ever since then it won’t cut without at least one charge about 75% through the job. Now I either have to return or buy separate battery (another $80 to $100). Buyer beware. Not a quality product.
