The corded nature of the device means you will need access to an electrical outlet and may have to manage the cord during use, which could be less convenient than a cordless model. The product does not include a collection box, so you will need to manually rake up the debris, which could be an added chore.

While the lightweight design is beneficial for maneuverability, it might not be as durable or robust as heavier, more industrial-grade models.
