VacuMaid SR36 Disposable Bag Central Vacuum - 5.7" 2-Stage Flow-Thru Motor

The SR36 is a compact 120-volt central vacuum power unit for a home with a tight mounting spot. It stands 23⅜ inches tall and pairs a 5.7-inch two-stage flow-through motor with a 27-quart canister that takes a disposable paper bag. VacuMaid sizes it for homes up to about 3,000 square feet, which suits a ranch, a townhouse or a modest colonial.

Measure the wall before the house

Most fitting questions come down to space. The body is 12⅞ inches across, and the manual asks for at least six inches of open room around it plus enough working space to open the canister. Mount the bracket to solid framing at a height where you can reach the lid comfortably.

What arrives in the carton

• The SR36 power unit with its canister and a standard disposable bag
• A wall mounting bracket

Hose, carpet powerhead, floor tools, wall inlets, tubing and fittings are separate purchases. You are buying the power unit, not a finished system.

Bags: the standard one and the optional upgrade

The bag in the canister is a two-layer paper bag with an inner liner. Reorder it as HPB1. VacuMaid also lists HPB2H, a HEPA-style bag, as an option. That is a swap you choose, not what ships in the box.

1. Unplug the unit and open the canister.
2. Slide the used bag's collar off the inlet stem, fold its flap over the opening and lift it out.
3. Open the new bag fully and seat its collar in the stem groove.
4. Confirm the protector plate and safety screen are still under the bag, then close the lid.

For the first month, look in weekly to learn how fast your household fills a bag. Replace it when airflow feels weak, even if the 27 quarts are not used up. If a bag ever splits, clean the affected screens as the manual describes before you run the unit again.

Sound, power and wiring

VacuMaid gives the SR36 a sound rating of 58 dB with the exhaust vented. Use it to compare models rather than as a prediction for your hallway. The motor draws up to 11.3 amps, so confirm the outlet and circuit against the rating plate instead of assuming any 120-volt outlet will do. Maximum motor figures are 561 air watts, 117 CFM and 142 inches of sealed water lift. They are separate peak ratings, and your pipe runs, bends and hose decide what reaches the floor.

Warranty

For an eligible single-family home in the United States, the original owner gets a lifetime limited warranty on the canister and 10 years on the motor and internal electrical parts. Canister coverage ends if the original owner no longer owns the system or the original building. Commercial use is covered for 90 days. Worn motor brushes, consumables, installation materials and the installation itself are not covered, and transportation or removal charges can fall to the owner. Hold on to the purchase record.

Questions people ask about the SR36

Is this a direct replacement for an older unit?

VacuMaid describes it as a quick and easy replacement for the Imperium CV260. Compare height, width and the pipe position before you count on that, since mounting holes and intake locations differ from system to system.

Is 3,000 square feet a promise?

No, it is VacuMaid's approximate guide.
