A power device may include a blade assembly (20) that includes at least one cutting blade and a motor assembly (30) that powers the blade assembly (20). The power device may further include a collection assembly (70). The collection assembly (70) may include a rigid frame (100) defining an opening (180) and a bag assembly (110) operably coupled to the rigid frame (100) at the opening (180). The bag assembly (110) may include a rotatable plate (160) having an axis (200) extending substantially parallel to the blade assembly (20), and a bag (170), where the bag (170) creates a seal between the rigid frame (100) and the rotatable plate (160).
