If you regularly use your robot vacuum, there's a chance that certain parts will need to be replaced after a while. This will help you to keep your robot in good condition and increase its lifespan. You can also upgrade your robot vacuum with extra accessories that aren't included with the current model. On this page, you'll find all of the accessories. For example, you could purchase a virtual wall that prevents your robot from going into certain areas, or you could replace the current side brushes with new ones once they're worn out. Note: most robot vacuum accessories are usually only compatible with the specifically named brands.
