• Quiet 58 dB Operation – Delivers strong performance while keeping operating noise impressively low.

• 6.6-Inch 2-Stage By-Pass Motor – Heavy-duty motor design uses separate cooling airflow for dependable long-term performance.

• Large 27-Quart Capacity – Provides generous dirt storage between bag changes.

• Compact 26-Inch Height – Offers substantial large-home capability in a noticeably shorter power-unit design.

• Galvannealed Steel Construction – Durable steel body is built for long-term strength and corrosion resistance.

• Powder-Coated Exterior – Adds a tough protective finish for years of permanent installation.

• Tangential Exhaust – Directs exhaust efficiently away from the motor and collection chamber.

The VacuMaid SR66 is designed for homeowners who want powerful central vacuum performance in a large home while preferring the clean, simple maintenance of a disposable bag system.

Rated for homes up to approximately 10,000 square feet, the SR66 produces 663 max air watts, 132 inches of water lift, and 139 CFM of airflow for strong performance through long central vacuum tubing runs.

Its top-fill design keeps routine maintenance straightforward. Collected dirt stays contained inside the disposable filtration bag, which is removed from beneath the top lid when replacement is needed.

The SR66 also stands out for its relatively compact 26-inch height, making it easier to install in locations where vertical space is limited without giving up large-home cleaning capability.

Top-Fill Bag System

The SR66 uses a top-fill disposable bag as its required collection system.

Instead of allowing dirt to collect loose inside a bottom bucket, debris is captured directly inside the filtration bag beneath the top lid.

This provides several practical advantages:

• Cleaner dirt disposal

• Less contact with collected dust

• Easier routine maintenance

• No loose debris inside the collection chamber

• Simple bag replacement

For customers who prefer a clean, contained maintenance system, the SR66 offers a straightforward alternative to a pure-dump cyclonic unit.

Powerful Large-Home Performance

A central vacuum must maintain strong suction and airflow throughout an entire network of tubing.

The SR66 produces up to:

• 663 Max Air Watts

• 132 Inches of Water Lift

• 139 CFM of Airflow

This combination provides the performance needed for large residential installations while maintaining effective cleaning at the hose.

Quiet 58 dB Operation

The SR66 operates at approximately 58 dB, making quiet performance one of its strongest features.

Because the power unit is normally installed away from primary living areas, such as in a garage, basement, or utility room, much of the motor noise is already isolated.

The SR66’s low sound output reduces that noise even further.

6.6-Inch Two-Stage By-Pass Motor

The SR66 uses a 6.6-inch two-stage bypass motor.

A bypass motor uses separate airflow to cool the motor instead of relying on the dirty vacuum air being drawn through the system.

This design is well suited for permanently installed central vacuum applications where durability and sustained performance are important.

Large 27-Quart Capacity

The SR66 provides a generous 27-quart collection capacity.

That gives it substantially more dirt storage than a typical portable household vacuum and helps reduce how often the bag needs replacement.

This is especially valuable in larger homes where more floor space naturally means more collected debris.

Compact 26-Inch Height

One of the SR66’s biggest installation advantages is its compact height.

At approximately 26 inches tall, it is significantly shorter than many large-capacity central vacuum power units.

That makes it a practical option for installations where wall height or available mounting space is limited.

Durable Steel Construction

VacuMaid builds the SR66 from rolled galvannealed steel rather than lightweight plastic.

The steel housing provides strength and long-term durability, while the powder-coated exterior helps protect against corrosion.

This construction is designed for a power unit that will remain permanently installed for many years.

Tangential Exhaust

The SR66 uses a tangential exhaust design to direct motor exhaust efficiently away from the power unit.

When installation conditions allow, exhaust air can also be routed away from occupied living areas for an even quieter and cleaner whole-home vacuum setup.

Flexible Right or Left Intake

The vacuum intake can be installed on either the right or left side of the power unit.

This gives installers more freedom when routing central vacuum tubing and positioning the SR66 in a garage, basement, utility room, or mechanical area.
