Robomow RS622

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

Living with it.

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.

Common questions

What people actually ask.

4 answered
OperationDoes 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.
OwnershipWhat 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.
OperationHow 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.
OperationCan 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.
