Husqvarna 570BTS Backpack Blower Review
The Husqvarna 570BTS is the high-output mid-range model in the Husqvarna backpack lineup, sitting between the popular 350BT and the flagship 580BTS. Its 65.6cc X-Torq engine produces 631 CFM and 232 MPH, which is a meaningful step above the 350BT’s 494 CFM for buyers with large residential lots, heavy leaf canopy, or blowing sessions that regularly run 45 minutes or longer. The BTS designation indicates a tube-mounted throttle control, which allows speed adjustment without moving the throttling hand from the tube to a body-mounted dial.

Performance
The jump from 494 CFM (350BT) to 631 CFM (570BTS) is noticeable in real-world use. Matted wet leaves that require two passes from the 350BT move in a single pass at moderate throttle from the 570BTS. On lots with an acre or more of lawn, heavy deciduous canopy, and consistent late-fall leaf accumulation, the extra output reduces total clearing time by a measurable margin. The 232 MPH airspeed is also well suited to moving debris off damp hard surfaces including driveways and paths where surface friction increases resistance.
Tube-Mounted Throttle
The tube-mounted throttle (BTS) is the feature that most distinguishes this model from the 350BT beyond raw output. Placing the throttle on the blower tube allows speed adjustment during use without repositioning the hand from the tube grip to the shoulder harness or body-mounted dial. For buyers who consistently vary speed during a session, managing open areas at reduced throttle and dense piles at full throttle, the tube throttle is a practical improvement.
Verdict
The 570BTS suits buyers with lots of an acre or more, heavy leaf volumes, or use patterns where session length and sustained high output matter more than purchase price. For buyers with lots under an acre and typical suburban leaf volumes, the 350BT provides adequate performance at a lower cost. The 580BTS review covers the flagship model for buyers evaluating the top of the range. The full comparison is in the best Husqvarna backpack blowers guide.
