The battery already had a charge so I immediately took it out for a test run. After a minute or two it became apparent that it was cutting great and that I had the setting too low (level 1) but it worked really well, quickly. With that, I kept going in my small yard and then switched to level 3 before heading to the curbside/sidewalk area where it again worked great. Not having a bag to catch grass wasn't an issue since I have a lawn/leaf rake which only gave me about 2 handfuls of cuttings at the end. I missed one spot raking so maybe I'd have had 3 handfuls total.The majority of grass clippings end up under the housing above the blade, which explains the the little scoop included that attaches to the handle. Once finished cutting I had it upside down and scoop-cleaned into the compost bin-no water needed (nor should any be used) in about 5 minutes or less. Simple.It was really quiet compared to a traditional gas-powered mower and probably on par with an electric mower and possibly more quiet than some others.What I liked most is I could move it really easily as it's very lightweight. It stores really well in my small shed. Overall, this is a great unit meant for small spaces that's easy to put together and use. I hope it lasts a long while.In my picture, you can see a bit of a U-Shape in my small lawn (divided with a thin fence) and that's something I couldn't do with my push-reel mower as it was a bit too big and also because the ground was bumpy due to dogs having been in the yard previously. I'd have to constantly lift it and set it down when I hit a corner, etc. No more.I'll add more updates later but for now, I'm really please. ### ⭐⭐⭐⭐⭐ Amazing mower for small yards!!! *by on Reviewed in the United States June 13, 2026* This thing is incredible!!! it works so well and makes mowing my relatively small backyard a breeze! Especially as a fairly sedentary, middle-age woman:). I did my whole backyard on just one charge of the battery, and this is lightweight, very, very easy to maneuver, even on some of the bumpy hilly rocky areas of my yard! And it cuts the grass perfectly! Not very loud either. I am so delighted with this purchase as our yard is really too small to invest in a giant, regular lawnmower, but cutting it with the Weedwhacker wasn’t working as well nor was it as easy as this mower! I highly recommend! Oh, and it was simple to put together too, and I love that it folds down so that it won’t take up much room at all to store! ### ⭐⭐⭐⭐⭐ This little guy works great. *by on Reviewed in the United States June 15, 2026* I'm almost 79 years old. To get to my very small back yard I have to go down two flights of steps. I was able to get my old electric mower down there but it was becoming more difficult. I can carry this little mower easily in one hand. The blade is only 9 inches wide so mowing is more like pushing a vacuum cleaner than a lawn mower. It clips the grass as short as I need it similar to my older electric mower. There are no clippings to empty or pick up, it mulches the grass down to very small bits and sends it back to the lawn. My front and back yard combined are less than one thousand square feet. The battery pack easily lasted long enough to do both. So far, I'm very pleased. ## Frequently Bought Together - RB 9" Cordless Lawn Mower, 40V 2Ah Battery & Charger, Upright Storage, Brushless Motor 6000RPM, 3 Cutting Heights (1.2"-2"), One-Hand Steering, Detachable Handle, Safe Tilt 20°-70° for Small Yards - RB EB20 40V 2Ah Li-Ion Battery – Powerful & Rechargeable Redback Swift Tools - RB 9" Replacement Lawn Mower Blades High-Carbon Steel Compatible with EB122C Durable, Sharp, Rust-Resistant --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/664557160-rb-40v-9-mini-cordless-lawn-mower-with-battery-charger](https://www.desertcart.us/products/664557160-rb-40v-9-mini-cordless-lawn-mower-with-battery-charger) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-06-23*
