Robomow RS630

Robomow · $1,399 street (MSRP $1,499) · Launched May 2013

Perimeter wire defines every square foot the RS630 cuts; within that boundary, it operates without intervention. Large cutting width and mulching deck suit 1/2-acre-plus lots where systematic coverage matters more than wire-free setup.

Ownership & reliability

How it holds up after the purchase.

Owner reports · manufacturer documentation

Wire breaks are the dominant failure mode; the mower itself is mechanically stable.

Owner reports across multiple seasons describe consistent cutting performance and rare electronic failures. Wire breaks from edging tools or aerators are the most reported service event; replacing and splicing wire is a documented, routine owner task.

Maintenance cadence
Every runEach useafter every cycle

Visually inspect blade disc for debris or damage.

Monthly12×a year

Clean underside of cutting deck; remove packed grass clippings from blade housing.

Seasonally4×a year

Replace blade disc (manufacturer-recommended interval; replacement discs run approximately $25-45 per set).

Inspect and test full perimeter wire circuit for breaks or signal degradation.

Clean base station charging contacts and rain sensor lens.

Yearly1×a year

Check and tighten perimeter wire staples or rebury wire segments where ground shifting has exposed them.

As neededVariesno fixed cadence

Splice or replace perimeter wire sections damaged by edging tools or ground work.

Safety flags
CautionSpinning blade deck exposedFree-floating blade spins during operation; keep children and pets off the lawn during scheduled runs.
CautionNo camera or object detectionThe RS630 has no vision system; it relies on contact bumpers to detect obstacles, not avoidance.
NotePerimeter wire currentLow-voltage signal wire is not a shock hazard; safe to handle, but disruption stops operation.
Common questions

What buyers actually ask.

5 answered
Operation
Does the RS630 require burying the perimeter wire, or can it be left on the surface?
Robomow documentation supports surface-laying with staples or burying at 1-3 cm depth. Surface installation is faster but risks damage from foot traffic and garden tools; manufacturer guidance recommends burying for permanent installations.
Operation
What happens if the RS630 encounters a wire break mid-season?
The mower will detect a signal loss and stop at the charging station, displaying an alert in the app. Owner reports describe wire breaks as the most common service event, typically caused by edging tools or aerators cutting across the buried wire.
Operation
Can the RS630 handle Bermuda or St. Augustine grass, or is it calibrated for cool-season turf?
Robomow documentation does not restrict the RS630 to specific grass types. Owner reports from warm-climate regions note the mower handles Bermuda and Zoysia effectively when cutting frequency is set to keep clippings short; thick St. Augustine may require more frequent scheduling.
Operation
Does the RS630 work in rain, and should it be scheduled for wet conditions?
The mower carries a rain sensor and will pause and return to base when rain is detected. Manufacturer guidance advises against mowing wet grass for both cutting quality and slope traction reasons; most owner configurations use the rain sensor as a default safeguard.
Compatibility
Is the RS630 Wi-Fi connected, and is the app required for normal operation?
The RS630 connects via Wi-Fi and uses the Robomow app for scheduling and configuration. Once a schedule is set, the mower operates without the app; Wi-Fi is not required for each mowing session, only for remote changes.
