The theoretical runtime of Robomow for a single charge varies from 40 to 120 minutes and depends on the particular model. However, the actual runtime may vary depending on the height and type of grass being cut.
But also high ambience temperatures can have influence on the runtime.
Average values are:
RKS 800 models: 50 minutes
RKS 1500 models: 105 minutes
RK1000 models: 40-50 minutes
RK2000 and RK3000 models: 80-90 minutes
RK4000 models: 110-120 minutes
TIP
Clean your mowing deck periodically, because this can also have a huge influence on the mowing times.
During high season or when it is wet, clean more often.
