What the specs work out to

Figures MowerFacts computes from Segway Navimow’s own numbers — not published by the manufacturer.

Coverage & ground

  • Rated work area2,000 m²
  • In acres0.49 ac
  • In square feet21,528 ft²
  • Max slope84% (40°)
  • Run time90 min
  • Charge time75 min
  • Noise68 dB

Gate & trailer fit

  • 32 in gateFits
  • 36 in gateFits
  • 48 in gateFits

Needs at least 23 in of clearance (estimated).

Fit uses the deck width plus 6 in for the discharge chute, because Segway Navimow doesn't publish an overall width — measure before buying if a gate is tight.

Work area is Segway Navimow's own rated maximum, converted from the 2,000 m² they publish. A robot rated below your lawn will not keep up with it.

Maximum slope is 84%, which is about 40°. Makers quote one or the other; they are the same figure, and 84% is not 84°.

Segway Navimow Navimow X420 questions

How wide does the Segway Navimow Navimow X420 cut?

The Segway Navimow Navimow X420 cuts a 17-inch (430 mm) swath with 12 blades. A robot makes up for a narrow cut by working for hours at a time, so the figure to compare is its work area.

How much does the Segway Navimow Navimow X420 weigh?

The Segway Navimow Navimow X420 weighs 63 lb (28.8 kg) as specified by Segway Navimow.

What slope can the Segway Navimow Navimow X420 climb?

The Segway Navimow Navimow X420 is rated for slopes up to 84%, which is about 40°. Manufacturers quote one or the other and they describe the same grade — 84% is not 84°. Steeper ground than this risks the wheels slipping.
