Robot mower blades FAQ

Start with your mower brand and model. The safest choice is the blade your mower maker sells for it. Third-party packs publish compatibility lists that are the seller’s claims, so compare length, center hole, thickness and screw with your current blade. See our brand fit guides.

Maker guidance varies: Husqvarna says main-disc blades typically last 3 to 6 weeks, Segway says every 80 working hours on some Navimow models, and Mammotion says flip at 50 hours and replace at 150 hours. See how often to replace robot mower blades.

Not always. A garage can shelter the mower and charger from sun, rain and debris, and from snow in some climates. Check your mower maker’s guidance.

It can, depending on your mower. Check your maker’s instructions on where the mower and any antenna or reference station should sit.

Measure your mower’s length, width and height, then add space for the charger and a few inches of clearance. Check the dock, too.

See the fit guides. Compatibility is the seller’s claim.
