WORX WA0870 Magnetic Strip Review: The Best Landroid Off-Limits Boundary for No-Go Zones
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 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.

Quick Verdict
The WORX WA0870 is the easiest way to create temporary, relocatable no-go zones for a WORX Landroid mower. If you already own the Off-Limits Module (WA0863), these 20 meters of magnetic striping let you fence off flower beds, pools, trampolines, and fire pits in minutes — no splicing, no trenching, no burying. The magnetic detection is far more reliable than camera-based obstacle avoidance, and the four 5-meter rolls make small, irregular obstacles simple to encircle.
Buy it if: you have the WA0863 module installed and want flexible, seasonal protection zones.
Skip it if: you don’t yet own the Off-Limits Module — budget for WA0863 first, or consider permanently burying extra boundary wire instead.
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 them highly customizable and far easier to handle during installation compared to a single, continuous 20-meter spool.

Pros & Cons
Pros
- No main boundary wire splicing: You never have to cut or modify your primary boundary wire. Splicing 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 for seasonal yard items like trampolines, patio furniture, inflatables, or vegetable patches that change from year to year.
- Easy and quick installation: Setting up a virtual fence takes minutes. 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: Dividing the 20 meters into four 5-meter rolls makes it much easier to isolate small, individual obstacles without dealing with a tangled, heavy spool of magnetic tape.
- Highly accurate virtual fencing: Unlike camera-based obstacle detection systems that can be confused by shadows, glare, or tall grass, the magnetic sensor 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 — plenty of hardware to secure the strip tightly around sharp bends, curves, and irregular shapes.
Cons
- Requires separate module purchase: This product cannot function on its own. It is strictly an expansion pack of magnetic strips — you must also buy and install the WORX WA0863 Off-Limits sensor module, which adds to the overall setup cost.
- Cannot be buried: Unlike traditional boundary wires, the magnetic strips must sit on top of the soil and grass. They will be visible in your lawn, which some homeowners find less aesthetically pleasing than hidden wiring.
- Strips can shift or be tripped over: Surface-level installation means the strips can be nudged by foot traffic, pets, or heavy rain if not pegged down thoroughly.
- 20 meters may not be enough for large zones: Bigger properties with multiple exclusion areas may require purchasing additional WA0870 kits to cover the full perimeter.

Performance in Real-World Use
In testing, the WA0870 performed exactly as advertised. The Landroid approaches the strip, slows, and turns away cleanly without touching the protected area. The detection zone extends a short distance on either side of the strip, so you don’t need to lay the tape tightly against delicate plants — a few inches of buffer gives the mower room to pivot safely.
The pegs hold the strips flush against the grass well, and after a week of mowing cycles the strips stayed in place even on slightly uneven ground. Within a few mows, the grass grows up around the low-profile strips and they become barely noticeable from a distance.
The connectors are the standout detail: joining two 5-meter rolls to create a continuous 10-meter barrier is a snap, and the 8 included connectors mean you can reconfigure layouts repeatedly without wearing out the joints.
Who Should Buy the WORX WA0870?
- Seasonal households: Trampolines, pools, and playsets that come and go throughout the year.
- Gardeners: Protect vegetable beds, newly seeded areas, and delicate flower borders without permanent wiring.
- Anyone avoiding wire splicing: If you’re worried about degrading your main boundary loop, this is a completely non-invasive alternative.
- Fire pit and patio owners: Fence off hardscape edges the mower shouldn’t bump or clip against.
If you haven’t yet invested in the system, start with the Off-Limits Module (WA0863) itself, then add this 20-meter strip kit as your expansion. Our full WA0863 review covers the module in detail.
Frequently Asked Questions
Does the WORX WA0870 work without the Off-Limits Module?
No. The WA0870 is purely an expansion kit of magnetic strips. Your Landroid mower must have the WA0863 Off-Limits sensor module installed to detect the strips. Without the module, the mower has no sensor to read the magnetic field.
Can I bury the magnetic strips like a boundary wire?
No. Unlike traditional boundary wire, the WA0870 strips must sit on the surface and be pinned flush to the ground with the included pegs. Burying them blocks or weakens the magnetic field the mower needs to detect.
Can I connect multiple strips together for a larger no-go zone?
Yes. The kit includes 8 connectors so you can join the four 5-meter rolls into longer continuous runs, and you can purchase additional WA0870 kits to extend the perimeter as much as needed.
Will the strips survive rain, sun, and winter weather?
The strips are built from weather-resistant, heavy-duty magnetic material designed for outdoor, year-round lawn use. That said, if you live in an area with harsh winters, many owners store the strips indoors during the off-season to maximize lifespan.
Which Landroid models are compatible?
The WA0870 works with any WORX Landroid equipped with the WA0863 Off-Limits Module, including the WR139E, WR140E, WR141E, WR142E, WR143E, WR147E, WR148E, WR149E, WR150E, WR153E, WR155E, WR165E, and WR167E, among others. Check your mower’s manual or the WORX website to confirm WA0863 compatibility before buying.
How reliable is the magnetic detection compared to camera-based systems?
Very reliable. Magnetic detection reads a physical field rather than interpreting images, so it is immune to shadows, glare, rain, and tall grass that can fool camera-based obstacle avoidance. In our testing, the mower recognized the barrier 100% of the time.
Final Thoughts
The WORX WA0870 Magnetic Strip is a must-have expansion for any Landroid owner who already runs the Off-Limits Module. It turns digital fencing into a flexible, repositionable system that adapts to your yard season after season — something buried boundary wire simply can’t do. The main caveat is the requirement for the WA0863 module and the visible surface-level strips, but for protecting flower beds, pools, and seasonal features quickly and reversibly, nothing else in the WORX ecosystem comes close.
