Powr-Flite Pro-Lite 4qt Backpack Vacuum BP4S
$349.00
The Powr-Flite Pro-Lite BP4S is a compact 4-quart commercial backpack vacuum that weighs just 10 lbs. A 1,200-watt / 10-amp motor delivers 100 CFM of airflow and 94 inches of waterlift, and it ships with a full 5-piece tool kit and 5 bags. Corded, 40-foot reach, quiet 62 dBA operation.
The Powr-Flite Pro-Lite BP4S is a compact, lightweight commercial backpack vacuum built for crews that want real cleaning power without carrying a heavy machine. At just 10 pounds with a 4-quart capacity, it is easy to wear through a full shift, yet its 1,200-watt, 10-amp motor moves 100 CFM of airflow with 94 inches of waterlift — enough to pull embedded dirt from carpet and hard floors alike. Anatomically formed, perforated-foam shoulder straps keep it comfortable, and at 62 dBA it runs about as quietly as normal conversation, so it is at home in offices, schools, and other noise-sensitive spaces. The stackable body stores and transports easily, and every BP4S is American engineered and assembled.
The BP4S ships ready to work: it includes a double-bend wand, a 17″ crevice tool, a 14″ Powr-Glide carpet tool, a 14″ hard floor tool, a 4-foot hose, and a starter set of 5 paper bags. It reaches with a 40-foot cord and is backed by a 1-year parts-and-labor warranty. As a value-focused Pro-Lite model it uses standard two-stage filtration — a disposable paper bag plus a pre-motor exhaust filter — rather than sealed HEPA, which is what keeps it light and affordable.

Powr-Flite Backpack Vacuum Comparison
The Pro-Lite BP4S is the lightest, most affordable backpack in the Powr-Flite range.

What bags does the Powr-Flite Pro-Lite BP4S use?
The BP4S uses the genuine Powr-Flite X1486 paper vacuum bag, sold in a 10-pack. It is a 4-quart bag sized specifically for the Pro-Lite BP4S and is not interchangeable with the larger Comfort Pro backpack bags.
Is the Powr-Flite BP4S a HEPA vacuum?
No. The Pro-Lite BP4S is a value-focused model that uses standard two-stage filtration — a disposable paper bag plus a pre-motor exhaust filter (part# X1488). If you require sealed HEPA filtration, look at the Powr-Flite Comfort Pro backpack line instead.
How much does the BP4S weigh and how loud is it?
The Pro-Lite BP4S weighs about 10 pounds and runs at 62 dBA — roughly the volume of a normal conversation — making it comfortable to wear through a full shift and quiet enough for offices, schools, and other occupied spaces.
What comes in the box with the BP4S?
Each BP4S includes a double-bend wand, a 17″ crevice tool, a 14″ Powr-Glide carpet tool, a 14″ hard floor tool, a 4-foot hose, and 5 starter paper bags. It has a 40-foot cord and a 1-year parts-and-labor warranty.
