Review: I love this thing (1 season) - I have a bad knee, anything that saves me from the weekly chore's gets extra bonus point from me. That being said this thing does do a great job. Install is a bit annoying (again bad knee) bending over and hammering in the wire. but once its setup i just loved to sit on the porch and watch the thing. Ran it for 2 hours 3x per week and the lawn always looked perfect. Got stuck maybe 4x the whole summer, had to go out and jostle it loose from a little divot in the lawn or something but for the time and sweat it saved me its well worth it. Blades are easy to change, seem to last plenty long. order a set of like 30 for 10$ and i bet a set would last me a whole season if i pushed it. 5 minutes to change them no reason not to every couple months. I do wish it used wifi so i could control it from anywhere, seems to only be bluetooth in the proximity of it. Also wish it would try and restart itself after a time when getting stuck, few times it did get stuck it was seemingly nothing just a slight bump in the lawn. if it would have tried to go again no doubt it would have been fine. Will see how it holds up. Will report back when it has any issue. Review: Not reliable if you travel for a few days or more - Not Reliable if you travel. You will have to pick up and bring back your it’s home often. It’s cuts really well and have had no issues w the battery. The boundary wire placement is an effort. If you can spend the extra dollars never get anything with a boundary wire again. My biggest regret. It runs well for a few days and I’m in love. Then I have to go out and bring it back. Either a boundary wire issue or can’t detect the wire or buggy software on app or it’s mows past an hour I scheduled and runs out of battery or it can’t find its way back often or on and on. ## Features - Highly intelligent robotic lawn mower: GARDENA SILENO Life automatically mows yards up to 8100 sq ft using PATENTED streak-free, with easy connectivity via Bluetooth EasyApp Control, Auto-Schedule and EasyConfig - Precise, silent navigation: Relax in your backyard while SILENO City traverses narrow spaces and tight corners while cutting your grass with one of the quietest in class noise levels of 57 dbA - Safe and reliable: The boundary wire ensures the Robotic Lawn Mower only mows the areas specified while collision sensors ensures the mower operates safely with no accidents or damage to your garden - All-weather and terrain: SILENO keeps mowing rain or shine and cuts all shapes of lawns within the boundary wire limits, from simple to complex including slopes of up to a 35 percent gradient (19°) - DIY Installation: Easily set-up your robotic mower at home, using our installation videos or user-friendly instructions and everything you need, provided in the box. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07JZ6YBZ3 | | Best Sellers Rank | #270,903 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #74 in Robotic Lawn Mowers | | Brand | Gardena | | Brand Name | Gardena | | Color | Large Yard | | Customer Reviews | 3.6 out of 5 stars 2,716 Reviews | | Cutting width | 6.3 Inches | | Global Trade Identification Number | 04078500043557 | | Item Dimensions D x W x H | 21.6"D x 14.9"W x 9.05"H | | Item Type Name | Robotic Lawn Mower | | Item Weight | 7 Kilograms | | Manufacturer | Gardena | | Manufacturer Part Number | 15101-20 | | Material | Polypropylene | | Material Type | Polypropylene | | Minimum Adjustable Cutting Height | 2 Centimeters | | Model Number | 15101-20 | | Operation Mode | Automatic | | Power Source | Battery Powered | | Required Assembly | No | | Smart Home Compatibility | Smart Home Compatible | | Style | Life | | Style Name | Life | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Gardena - **Power Source:** Battery Powered - **Material:** Polypropylene - **Color:** Large Yard - **Style:** For Europe - **Item Weight:** 7 Kilograms - **Cutting Width:** 6.3 Inches - **Operation Mode:** Automatic - **Product Dimensions:** 21.6"D x 14.9"W x 9.05"H - **Assembly Required:** No ## Images ![GARDENA 15101-20 SILENO Life - Automatic Robotic Lawn Mower, with Bluetooth app and Boundary Wire, one of The quietest in its Class, for lawns up to 8100 Sq Ft, Made in Europe, Grey - Image 1](https://m.media-amazon.com/images/I/718zE0hYHFL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I love this thing (1 season) *by A***. on January 10, 2024* I have a bad knee, anything that saves me from the weekly chore's gets extra bonus point from me.

This thing is surprisingly really good. It’s definitely worth the money but you’ll have to put in some work to get it setup properly so that it doesn’t require too much maintenance. I’d recommend burying the boundary wire and the guide wire after a few weeks. I just used an edger to make a cut in the grass then push the wire into the kerf. You might want to lay it on the ground at first to find out how the mower cuts before burying it. I found that you don’t need a boundary wire around most obstacles like a kids play set and swings. The mower will just bump into walls and obstacles then just change direction and keep cutting. I found it cuts closer to walls if the wire is right up against them. You might want to stay about 3 inches away from concrete slabs and driveways so it cuts closer to the edge but not right on the edge in case you want to use an edger. Also when I got the mower it had a security pass code on it already and I almost returned the thing because resetting the code requires an old style usb and a computer. But I luckily guessed the code and it started working. The code I guessed was up, left, down, right, then hit the check mark in the middle. Just counter clockwise from the top. Usually during setup you set the code but for some reason it already had one. ## Frequently Bought Together - GARDENA 15101-20 SILENO Life - Automatic Robotic Lawn Mower, with Bluetooth app and Boundary Wire, one of The quietest in its Class, for lawns up to 8100 Sq Ft, Made in Europe, Grey - GARDENA 15020-20 Charging Station Cover, Grey - Gardena 4088-60 490 ft (150m) Boundary Wire, for Gardena Robotic Lawn Mowers, Used to Define perimters and Guide Robotic Lawn mowers --- ## 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.jp/products/445773819-gardena-15101-20-sileno-life-automatic-robotic-lawn-mower-bluetooth](https://www.desertcart.jp/products/445773819-gardena-15101-20-sileno-life-automatic-robotic-lawn-mower-bluetooth) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-06-18*
