Pretty Good with limitations
Your review: Has a good suction for it's weight. Nice backpack padding and adjustments.
Pros: Light and sturdy. nice set of attachments. Secures to most body types with the latch adjustments. Great ON/OFF switch located at your left waist area; one of the nicest features. The bag filters can be replaced quickly and efficiently
Cons: The paper bags will not hold up in an industrial environment where anything with any bit of weight to it gets sucked up. The paper bag will rip and all gets caught in the fabric bag. We ended up doubling the fabric bag and empty it periodically. The paper bag would be good for dust particles and the like only.
