Introducing the BP4S Pro-Lite Backpack Vacuum: Lightweight Cleaning Power
Looking for a vac that won’t weigh you down? The Powr-Flite Pro-Lite Backpack Vacuum 4 Quart is your ticket to getting the job done fast and easy. At just 10 lbs., this BP4S model is a featherweight champ, built for pros who need to move quick in tight spaces—think offices, schools, or small commercial gigs.
With 100 CFM and 100 inches of waterlift, it’s got the suction to pull dirt from carpets and hard floors, earning a CRI Bronze rating for solid cleaning performance.
This vac’s high-impact polypropylene body can take a beating, and the 50 ft. cord lets you cover ground without unplugging. The 4-stage filtration keeps dust locked down, while the standard tool kit—double-bend wand, 17” crevice tool, and more—makes it a breeze to hit every nook and cranny. It’s simple, tough, and ready to roll.

Powr-Flite 4 Quart Backpack Vacuum: Compact and Mighty
Don’t let the 4-quart capacity fool you—this little beast handles big messes without breaking a sweat. Covering 9.5” x 9” x 22.5”, it’s compact enough to slip into tight spots but still packs 1200W of power. The 67 dBA sound level means you won’t be the loudest thing in the room, perfect for daytime cleaning in busy spaces.
Safety First with Thermal Protection
Ever had a vac overheat mid-job? Not with this one. The BP4S comes with a thermal overload switch that shuts the motor down if airflow gets blocked—like from an overfull bag or clogged hose. Just clear the blockage, let it cool, and you’re back in action. It’s a smart feature that saves your motor and keeps your crew moving.
P-Clamp Cord Security: Stay Safe, Stay Focused
Powr-Flite doesn’t mess around with safety. This vac includes a P-Clamp to secure the 50 ft. cord, cutting the risk of electrical mishaps if the cord gets loose. It’s a small detail that makes a big difference—keeping you focused on cleaning, not troubleshooting. Plus, the cord hooks onto the harness frame post-use, so you’re not tripping over it.
