Frequently Asked Questions

Can a cheap robot mower handle 1/2 acre?
Not really. Cheap mowers (under $1,500) have small batteries (150-200 Wh) that won't complete a 1/2-acre mow cycle on a single charge. You'll need a mower with at least 400 Wh battery, which means stepping up to the $2,000+ tier.
How often should a robot mower run on a 1/2-acre lawn?
2-3 times per week during growing season (April-October in most US climates). Each session takes 90-150 minutes depending on the mower. Set the schedule so the mower runs on alternate days (e.g., Monday, Wednesday, Friday).
What's the cheapest robot mower that can handle 1/2 acre?
The Worx Landroid Vision Cloud WR320 ($1,999) is the cheapest wire-free mower we'd recommend for a 1/2-acre lawn. It has a 200 Wh battery and 180-minute runtime, which is enough for a 1/2-acre mow cycle. The Mammotion LUBA 2 AWD 3000X ($2,499) is a better pick if you can afford it.
