Robomow RS622

Robomow · MSRP $1,799 (discontinued model) · Launched Jan 2014

The RS622 is a wire-guided workhorse designed for mid-size residential yards. Its predictable boundary operation makes it reliable within defined perimeters; the trade-off is the absence of adaptive routing or wireless boundary options.

Ownership & reliability

How it holds up after the purchase.

Owner reports · manufacturer documentation

Established wire-guided operation with proven field performance; perimeter-wire integrity remains the critical failure point.

Multi-year owner reports show consistent performance within documented boundaries. Main issues are perimeter-wire breakage (from lawn equipment or weather damage) and gradual blade dulling reducing cutting efficiency.

Maintenance cadence
Weekly52×a year

Empty grass collection bin; visually inspect wire for debris or damage.

Monthly12×a year

Clean undercarriage and check blade sharpness; note any dulling for next seasonal replacement.

Seasonally4×a year

Blade replacement ($35–45 per set); full perimeter-wire inspection and repair as needed.

NotePerimeter-wire contact risk during yard workKeep wire visible or safely buried to prevent accidental trips or contact with garden equipment.
Common questions

What buyers actually ask.

4 answered
Operation
Does the Robomow RS622 require burial of the perimeter wire?
No. Surface installation with lawn staples or grooved channels is standard. Burial is optional and generally unnecessary for residential yards.
Ownership
What is the blade replacement interval and cost for the RS622?
Blades typically need replacement every 12–18 months of weekly mowing. Aftermarket replacement sets cost $35–45 from specialty suppliers.
Operation
How much yard area does the RS622 cover per charge?
Approximately 0.6 acre per full charge cycle, depending on grass density. Denser turf reduces coverage; lighter grass extends runtime.
Operation
Can the RS622 be operated without a perimeter wire?
No. The RS622 exclusively uses perimeter-wire guidance. Wireless or GPS boundaries are not available on this model.
