Maintaining a pristine lawn has evolved significantly with the advent of robotic lawn mowers. Homeowners no longer need to spend their weekends pushing heavy machinery under the hot sun. However, even the smartest robotic mowers can struggle when navigating around delicate flower beds, newly planted trees, swimming pools, or seasonal backyard additions like trampolines and fire pits. While laying down a permanent boundary wire is the standard solution, doing so for temporary or highly complex areas can be a major hassle.
This is where the WORX WA0870 20M Magnetic Strip for Off-Limits Accessory comes into play. Designed specifically to work in tandem with the WORX Landroid Off-Limits Module (WA0863), this product offers a modular, non-invasive digital fencing system. It allows you to quickly establish “no-go” zones in your yard without having to splice, cut, or reroute your primary boundary wire. In this comprehensive review, we will dive deep into the features, performance, pros, and cons of the WORX WA0870 to help you decide if it is the right upgrade for your smart lawn setup in 2026.

Product Overview
The WORX WA0870 is an expansion kit consisting of 20 meters (approximately 66 feet) of heavy-duty magnetic striping, alongside the necessary pegs and connectors. It is designed to extend the functionality of the WORX Landroid Off-Limits digital fencing system. When laid out on your lawn, these strips emit a localized magnetic field that is actively detected by the Off-Limits sensor module installed on the undercarriage of your Landroid robotic mower. As soon as the mower approaches the strip, it instantly recognizes the magnetic barrier as a “virtual fence” and turns away safely, protecting your landscaping and the mower itself.
It is important to understand that the WORX WA0870 is an accessory expansion kit. To utilize these magnetic strips, your WORX Landroid mower must already have the Off-Limits Module (WA0863) installed. The strips are packaged in four convenient 5-meter (16.5 feet) rolls, making it highly customizable and far easier to handle during installation compared to a single, continuous 20-meter spool.

Pros
The WORX WA0870 WORX WA0870 Magnetic Strip: Best Landroid Off-Limits Boundary system offers several distinct advantages that make automated lawn care much more flexible and stress-free. Here are the primary benefits of integrating this accessory into your yard:
- No Main Boundary Wire Splicing: The greatest advantage of using this magnetic strip is that you do not have to cut or modify your main boundary wire. Splicing boundary wires can degrade signal quality over time and increases the risk of wire breaks. With the WA0870, you simply lay the strip down and pin it.
- Highly Modular and Portable: Unlike buried boundary wires, these magnetic strips can be picked up, relocated, or reshaped at any time. This is incredibly useful if you have seasonal yard items like trampolines, patio furniture, inflatables, or vegetable patches that change from August to August.
- Easy and Quick Installation: Setting up a virtual fence takes minutes. You only need to lay the strip around the obstacle, secure it flush to the ground using the included pegs, and let your Landroid do the rest. No trenching or digging is required.
- Convenient Pre-Cut Segments: By dividing the 20-meter strip into four 5-meter rolls, WORX makes it much easier to isolate small, individual obstacles without dealing with a tangled, heavy spool of magnetic tape.
- Highly Accurate Virtual Fencing: The magnetic detection system is incredibly reliable. Unlike camera-based obstacle detection systems that can get confused by shadows, glares, or tall grass, the magnetic sensor on the Landroid detects the physical magnetic field 100% of the time, ensuring your mower never breaches the designated zone.
- Generous Accessory Package: The kit includes 24 sturdy lawn pegs and 8 connectors. This gives you plenty of hardware to secure the strip tightly around sharp bends, curves, and irregular shapes in your yard.

Cons
While the WORX WA0870 is an excellent accessory, it does have a few limitations that buyers should keep in mind before making their purchase:
WORX WA0870 20M Magnetic Strip for Landroid Robotic Mower - Virtual Fence for Flower Beds & Pools
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
- Requires Separate Module Purchase: This product cannot function on its own. It is strictly an expansion pack of magnetic strips. To use it, you must purchase and install the WORX WA0863 Off-Limits sensor module on your Landroid mower, which adds to the overall setup cost.
- Cannot Be Buried: Unlike traditional boundary wires, these magnetic strips must sit on top of the soil and grass. If you bury them too deep, the mower’s sensor will not be able to detect the magnetic field. Consequently, the strip remains visible on your lawn until the grass grows over and naturally conceals it.
- Vulnerable to Lawn Care Tools: Because the strips lie on the surface of the grass, they can easily be damaged or shifted if you use a manual line trimmer (weed whacker), lawn aerator, or dethatcher near the virtual fence boundaries. Care must be taken during routine yard maintenance.
- Limited Length for Large Properties: While 20 meters (66 feet) is plenty for a couple of flower beds or a trampoline, it can run out quickly if you have a massive yard with numerous obstacles. Buying multiple kits can become quite expensive.

Customer Reviews Analysis
With an average rating of 4.3 out of 5 stars across 397 reviews, the WORX WA0870 WORX WA0870 Magnetic Strip: Best Landroid Off-Limits Boundary has been well-received by the robotic mowing community. Customers appreciate the practical solution it offers to common yard navigation problems.
The vast majority of positive reviews focus on the sheer convenience of the system. Users love how they can instantly protect temporary setups, such as seasonal fire pits, above-ground pools, and children’s play areas, without having to dig up their lawns to route boundary wires. Many reviewers note that the Landroid detects the magnetic field flawlessly, stopping and turning around immediately upon approach.
On the flip side, critical reviews generally center around two main issues: cost and peg limitations. Some users feel that the price of the extra magnetic strips is somewhat high for what is essentially rubberized magnetic tape. Others have mentioned that if you have a highly winding or complex shape to fence off, you may run out of the included pegs quickly, requiring you to purchase extra garden staples or fashion your own DIY wire pins to keep the strip completely flush to the ground.

Frequently Asked Questions (FAQs)
1. Can I use the WORX WA0870 magnetic strip without buying the Off-Limits Module?
No, you cannot. The magnetic strip itself is passive. It requires the WORX WA0863 Off-Limits Module to be installed on the underside of your Landroid mower. The module contains the active sensors that detect the magnetic field emitted by the WA0870 strip. Without the module, the mower will simply run over the strip without stopping.
2. Can the magnetic strip be cut to specific lengths?
Yes! The magnetic strip can easily be cut with standard household scissors or utility shears to perfectly match the perimeter of the area you want to block off. You can use the included connectors to join pieces together if needed.
3. How close to the ground does the magnetic strip need to be?
The magnetic strip must be pinned as flat and flush to the ground as possible. If there are loops or raised sections, the Landroid’s bumper or blades could catch on the strip, potentially cutting it or dragging it across the lawn. Over time, the grass roots and thatch will naturally pull the strip down, making it virtually invisible.
4. Will the magnetic strip survive winter and harsh weather?
Yes, the WORX WA0870 is made of durable, weather-resistant magnetic material designed to withstand rain, sun, and temperature fluctuations. However, if you live in an area with heavy snow and plan to use a snowblower or plow over your grass in the winter, it is highly recommended to roll up the strips and store them indoors until spring to prevent mechanical damage.

Who Should Buy This Product?
The WORX WA0870 is an ideal purchase for:
- Homeowners with Dynamic Yards: If your yard layout changes throughout the year—such as setting up a trampoline in the summer, placing lawn chairs in the spring, or adding holiday decorations in the winter—this modular fencing is perfect.
- Garden Enthusiasts: If you frequently plant new flower beds, vegetable gardens, or saplings that require temporary protection until they are fully established, these strips offer a quick, painless solution.
- Landroid Owners Seeking Convenience: If you want to avoid the tedious task of cutting, splicing, and re-burying your main boundary wire every time you add a new feature to your yard, this accessory is a must-have time-saver.
