Power-unit buying guides, sizing math, and head-to-head comparisons across cyclonic, filtered, and bagged designs.
You bought a house, opened the utility room, and found a dusty AirVac canister bolted to the wall. Or the air vac central vacuum system you’ve counted on for years just quit mid-hallway and won’t restart. Every search result implies the brand is still active. It isn’t. That one fact reshapes every decision ahead of … Read more
The titan central vacuum system shows up on retailer sites at a price that feels reasonable, with specs that read well. The problem?

You searched “signature central vacuum system” expecting one clear answer, and the internet handed you three different machines plus a wall of dealer spin. The claim keeping buyers stuck: that every Signature unit runs a premium tangential bypass motor, when the budget models quietly ship with cheaper flow-through motors the listings never mention.

You moved in, opened the garage door, and found it: a heavy steel canister bolted to the wall with “AstroVac” stenciled on the side.
