Pros & cons
Robomow RK1000
- ✓Offset blade disc and near-wire following trim edges most wire mowers leave for the string trimmer
- ✓Pendulum-suspended floating deck keeps the cut even on bumpy ground
- ✓45% slope rating and a 0.6-3.9 in height range that covers warm- and cool-season grass
- ✓Owners report it is quiet and simple to set up and clean
- ✓3-year warranty and a 4.3 in color touchscreen for programming at the mower
- ✗Only 40-50 minutes per charge, and owners say a lawn near the 10,000 sq ft ceiling does not get finished in one cycle
- ✗Bluetooth-only app that owners report loses connection more than it connects
- ✗Random-pattern mowing with bumper-only obstacle handling
- ✗Parts are expensive and slow to get since the MTD sale; Robomow's US site now redirects to a parts store
Greenworks Optimow 33H
- ✓High-cut 2.4-4.0 in range is right for fescue and bluegrass
