This is for owners of several acres with steep, rough ground who also want snow or leaf modules later. Tom's Guide found it climbed a steep incline and rarely hit obstacles, but setup took a weekend and it needed an Ethernet cable. Anyone with a normal suburban lawn should skip it and buy a simpler wheeled mower.
Best for: multi acre, steep properties. Skip if: your lawn is under an acre.

What independent reviewers found
- Tested the Yarbo Pro mower on about an acre for roughly a month. Mowing was strong, it climbed a steep backyard incline and rarely hit obstacles, and blades stayed sharp. Setup took an entire weekend and Wi-Fi was unreliable, so the tester ran an Ethernet cable through a window. Verdict: overkill for most homes.
- Tom's Guide
- Used the Yarbo Core with the standard mower module (20 in, two discs with five blades each) for a few months. It mowed the whole garden in about 2 hours and came back with 40% battery. Setup is involved and module swaps are heavy. Note this was the classic mower module, not the Pro.
- Stuff · 4/5
- Used Yarbo with its lawnmower module for a mowing season. It handled slopes and uneven ground, and weekly updates improved it, but GPS signal dropped at random, it hit a car once and was hard to pull out of mud. The module variant was not named.
