Our top picks
Why people look for Navimow X4 alternatives
On paper the X4 is the strongest mid size mower we cover: four wheel drive, an 84% slope rating, a 17 in dual disc cut with a 0.75 to 4 in height range, antenna free network RTK plus 360 degree vision, IP66, and a Navimow app rated 4.7 on the App Store from about 3,500 ratings. The problem is buying one:
- It was sold out. Both the X430 (1.0 acre) and X450 (1.5 acres) showed Sold Out on navimow.com on October 19, 2026, and the X4 was not on Amazon.
- Connect+ renews. Cellular features are free for 1 year on the X430 and 2 years on the X450, then renew yearly.
- Wide body. At 24 in, it needs clear passages between lawn zones.
- Runtime as area. Navimow publishes up to 9,600 sq ft per charge, not minutes.

How to choose
Slope decides first. Measure your steepest section with a phone app. Above 70%, only the Worx 4WD (84%) and Luba 3 (80%) are rated for it among available models. Between 45% and 70%, add Husqvarna's 435 iQ AWD and Yarbo.
Then area. Buy above your mowable area, not your lot size. Under 0.37 acre, the Navimow i2 or a Luba 3 1500. Up to 1.5 acres, the Luba 3, Worx WR346 or Husqvarna 435 iQ. Past 2 acres, Yarbo.
Then navigation. RTK needs open sky; LiDAR and vision work under trees and next to the house. The Luba 3 combines all three. Mova and the Navimow i2 skip RTK entirely. Husqvarna's EPOS uses satellites plus cellular.
Then software. A mower is only as good as its app. App Store ratings: Navimow 4.7, Husqvarna Automower Connect 4.5, Mammotion 2.9, Worx Landroid 2.9.
Tall grass. The X4 cuts up to 4 in. For the same height, choose the Luba 3 H version or the Husqvarna 440 iQ.
The 2026 FCC rule
On July 28, 2026 the FCC added foreign produced robotic devices, including robot lawn mowers, to its Covered List. Consumer Reports explains that already authorized models can still be sold and used and can receive updates until January 1, 2029, while new models need conditional approval. Buy current models from the brand or an authorized retailer.
How we picked
We started from the mowers in our best robot lawn mowers, wire free and large yards guides and from the models reviewers compare with the X4, especially the Luba 3. Each pick is wire free capable and beats or matches the X4 on something its buyers want: availability, slope, area, navigation without satellites, edge trimming or app rating. Specs come from each brand's page; we compared published facts and did not test the mowers. See the Navimow X4 review and the X4 vs Luba 3 head to head.
Frequently asked questions
Why is the Navimow X4 sold out?
Navimow does not say. Both the X430 and X450 showed Sold Out on navimow.com on October 19, 2026, and the X4 was not listed on Amazon. Check Navimow's store and authorized dealers, and be careful with third party sellers.
What is the best alternative to the Navimow X4?
The Mammotion Luba 3 AWD. It is AWD, rated for 80% slopes, available in 0.37, 0.75 and 1.25 acre versions, and combines LiDAR, network RTK and vision. Its weak spot is software: the Mammotion app rates 2.9 on the App Store.
Navimow X4 or Mammotion Luba 3?
On paper the X4 wins on slope (84% vs 80%), cut width (17 in) and app rating (4.7 vs 2.9). The Luba 3 wins on navigation redundancy, runtime (up to 215 minutes) and availability. See our full Navimow X4 vs Luba 3 comparison.
Which mower matches the Navimow X4 on hills?
The Worx Landroid Vision Cloud 4WD, also rated for 84% (40 degrees). The Mammotion Luba 3 is rated for 80%, and Husqvarna's 435 iQ AWD and Yarbo for 70%.
Do these mowers need a boundary wire?
No. Every pick here is wire free. Husqvarna's 435 iQ AWD and 440 iQ can still use a physical wire if you prefer, but both support virtual boundaries through EPOS.
Does the FCC rule affect robot mowers?
Yes, for new models. On July 28, 2026 the FCC added foreign produced robotic devices, including mowers, to its Covered List. Consumer Reports says already authorized models can still be sold and get updates until January 1, 2029.
