Quick Answer: A robot lawn mower garage is a roof for the charging dock, not a rain shelter — modern mowers are IPX5/IPX6-rated and shrug off water, but they sit in direct sun 24/7, and Mammotion’s own garage guide names UV exposure and temperature swings as the biggest causes of long-term damage. Expect to pay $149.99 for Segway’s Navimow i-Series garage, $209 for Mammotion’s LUBA/YUKA garage, and $349 for Navimow’s X-Series version — or well under that for a universal steel-frame carport on Amazon, which works fine as long as it clears your dock and doesn’t put a metal roof over an RTK antenna. The mower must be able to drive in and out on its own: open front, no lip, antenna outside the roofline.
Search volume for this accessory keeps climbing for a simple reason: people spend $700–$2,400 on a machine and then watch it bake on the south side of the lawn all summer. The mower itself mostly doesn’t care about rain. It cares about the sun. This guide sorts the three ways to put a roof over it — OEM, universal, DIY — and the three fitment rules that decide whether a garage helps or actually breaks your mower’s automation.
Robot mower garages, by the numbers
- $209 — Mammotion’s official garage for the LUBA and YUKA series. Listed at $209 on Mammotion’s US store and carried at Home Depot (model MTL24GARUS03), sized for mowers up to a 15.8-inch cutting width and compatible across the Mammotion lineup. In May 2026, Mammotion ran LUBA 3 AWD promotions that threw the garage in free with the mower, per 9to5Toys — worth checking before you buy one separately.
- $149.99 — Segway’s Navimow i-Series protective garage. Listed on navimow.com at $149.99 against a $199.99 regular price. The X-Series equivalent is $349, and Segway has bundled it free with X430 purchases and sells an X450-with-garage bundle outright — a sign of how standard the accessory has become.
- UV and temperature swings, not rain — the actual threat. Mammotion’s own garage guide is blunt that ultraviolet exposure and heat cycles do the most long-term damage to an outdoor-parked robot; rain is what the IPX rating already handles. Sunseeker makes the same point in its product name: it sells its L22 dock shelter as a “Sunproof Garage.”
- 35.5 × 29 × 17 inches — what “universal” actually means. A typical universal steel-frame garage on Amazon (600D oxford fabric, rust-proofed frame) lists interior dimensions of 35.5 × 29 × 17 inches and claims fitment across Lymow, Segway, Mammotion, Husqvarna and Worx. The claim is honest only if your dock-plus-mower footprint fits inside it — measure first.
- Two OEM house lines from Husqvarna. Husqvarna splits its Automower House by series: an iQ Series House (also fitting the 560, 580 and 580L) and an X-Series House for the 430X, 450X, 520 and 550, both with a fold-up top so you can reach the keypad without lifting the house off. Pricing is dealer-set in the US; genuine house kits for older 400/500-series machines also circulate on Amazon.
OEM vs universal vs DIY: the comparison
| Option | Price | Fits | Material | The catch |
|---|---|---|---|---|
| Mammotion Garage (LUBA / YUKA) | $209 | All Mammotion mowers, up to 15.8" cutting width | Weather-resistant panel roof | Watch for free-with-mower promos before paying separately |
| Segway Navimow i-Series Garage | $149.99 (reg. $199.99) | Navimow i105 / i110N docks | Molded cover | i-Series only — X owners need the $349 version |
| Segway Navimow X-Series Garage | $349 | X3 / X4 series docks | Molded cover | Frequently bundled free with X430/X450 — check first |
| Husqvarna Automower House (iQ / X-Series) | Dealer-priced | iQ series + 560/580/580L, or 430X/450X/520/550 | Hard shell, fold-up top | Two separate versions — buy by your series, not "Husqvarna" |
| Universal steel-frame carport | Budget pick | Anything that fits ~35.5 × 29 × 17 in interior | 600D oxford on steel frame | Measure mower + dock; fabric life is a few seasons in hard sun |
| DIY build | Lumber budget | Whatever you design | Wood, polycarbonate | Open front, no metal roof over an RTK antenna, ventilation gap |
The pattern in that table: the price tracks the dock, not the roof. Wire-free mowers with RTK antennas and sculpted docking stations get molded OEM garages designed around them; wired mowers with a simple charging ramp can live under anything that keeps the sun off.
Universal Robot Mower Garage — Steel Frame + 600D Canopy
- Listed fitment across Lymow, Segway Navimow, Mammotion, Husqvarna and Worx — but verify your dock-plus-mower footprint against the interior dimensions before ordering.
- Fabric-and-frame construction is the cheapest real protection against the two things that matter: UV and hail.
- Open-fronted carport design keeps the automation intact — no doors, no lip, nothing for the mower to negotiate.
A garage is the rare mower accessory that fits in a normal delivery box — try Amazon Prime free for 30 days and it can be over your dock in two days, before the next heatwave gets there.
Mammotion Garage for LUBA & YUKA
- Shaped around Mammotion's own docks — no guesswork about whether an AWD LUBA clears the roof.
- Mammotion's garage guide is the source for the UV-and-heat argument; this is the company's own answer to it.
- Check current LUBA promotions first: 2026 deals have included this garage free with the mower.
Husqvarna Automower House
- Buy by series: the iQ Series House and X-Series House are different products for different docks.
- The fold-up top matters on keypad-equipped Automowers — you check status without lifting the house.
- Genuine house kits for older 400/500-series Automowers are still sold on Amazon.
The three fitment rules
1. The garage covers the dock, and the mower must reach it unaided. A robot mower garage is not storage furniture — it is an open-fronted roof over the charging station, and the mower’s approach line to the dock must stay completely clear. No door, no flap, no threshold lip at the entrance. If the mower has to be lifted in, every mowing cycle now involves you, which defeats the entire product category.
2. Keep the antenna out from under the roof. This is the rule that separates wire-free mowers from everything else. RTK-based systems — Mammotion LUBA, Segway Navimow, Husqvarna’s EPOS models — depend on satellite reception, and several put a reference antenna at or near the dock. A roof over the antenna, especially a metal one, degrades exactly the signal the mower navigates by. OEM garages are designed around their own antennas; with a universal or DIY build, mount the antenna outside and above the roofline and use fabric or polycarbonate overhead, never sheet metal.
3. Measure the footprint, then add clearance. Dock plus parked mower plus a few inches on every side, checked against the interior dimensions in the listing — a 35.5 × 29 × 17-inch universal comfortably swallows a Navimow i105 but is a squeeze for a full-size LUBA on its station. The clearance is not cosmetic: the mower charges in there, and charging generates heat that wants somewhere to go.
When to skip the garage entirely
Honest cases against: if your dock already sits under a deep porch overhang or on the north side of the house out of direct sun, a garage duplicates shade you already have. If you bring the mower indoors every winter anyway (you should — a garage handles the season, not the freeze; see the maintenance guide for the winter routine), the garage’s job is only May-to-October sun and hail. And if you are still choosing the mower itself, buy the machine first and the roof second — promotions from both Mammotion and Segway have repeatedly thrown the garage in free, and $150–$350 of accessory budget is better spent going up one mower tier if you have to choose.
What a garage will not do: it will not stop theft (a determined thief lifts garage and mower together — GPS tracking and PIN locks do that job), it will not keep blades sharp, and it will not extend battery life beyond what avoiding heat soak already does. It is a roof. The case for it is that the sun is relentless and plastic is not.
Where this fits in the ownership cost
On top of the mower itself you are realistically budgeting for replacement blades every season, electricity, and possibly a garage — the full picture is in our robot lawn mower cost breakdown. The garage is the only one of those that is a one-time buy, and the only one that is legitimately optional. If your dock placement is still undecided, read the installation guide first — a dock sited in shade with clear sky for the antenna needs less protecting than one in full sun.

The bottom line
Buy a garage to fight the sun, not the rain — the IPX rating already handles water, and Mammotion’s own guidance points at UV and temperature swings as what actually ages an outdoor-parked mower. Wire-free RTK mower? The OEM garage ($149.99–$349, frequently free in bundles) is worth it because it is guaranteed not to break your dock or your satellite fix. Wired mower with a plain charging ramp? A universal steel-frame carport does the same job for less, provided you measure the dock-plus-mower footprint against the listing’s interior dimensions. And whatever you put up: open front, no lip, antenna in open sky. The garage should be the one accessory your mower never notices is there.
