A small minority (approx. 12%) mention it’s larger than anticipated, which could affect users needing super-lightweight portability.
Evaluating the Design: Utility and Ergonomics
The SC3700A’s traditionally styled canister design is built for efficient, large-area cleaning on multiple surfaces. The high-capacity, 3.88 qt. bag reduces emptying frequency, favoring users with substantial square footage.
Attachments include a combination carpet and bare floor tool, plus crevice and upholstery heads, targeting stairs, tight corners, and furniture. The two-piece, sturdy metal wand increases both reach and durability, a feature commercial cleaning crews will especially appreciate.
Performance: Quiet Operation Without Sacrificing Power
The vacuum’s 9.0 amp motor is designed to handle thick carpets and bare floors equally well, according to customer reports. At just 68 dBA, noise output stays well below typical upright and even many canister vacuums, ensuring minimal disruption for people and pets.
Users frequently mention being able to hold a conversation or make phone calls during operation, which is nearly impossible with most comparably priced units.
Accessories and Versatility in Day-to-Day Scenarios
Having a variety of onboard accessory tools ensures coverage from floors to blinds and upholstery. The SC3700A’s combo tool easily toggles between carpets and hard floors, while the crevice and upholstery accessories are helpful for edges, car interiors, and fabric furniture.
The long hose and cord permit cleaning of multiple rooms or a large workspace without the need to frequently unplug and relocate the machine.
How the SC3700A Compares to Competing Canister Vacuums
| Feature | Sanitaire SC3700A | Bissell Zing Bagged 2154A | Hoover Commercial CH30000 PortaPOWER |
|---|---|---|---|
| Motor Power | 9.0 Amp | 10.0 Amp | 7.4 Amp |
| Noise Level | 68 dBA | About 75 dBA (est.) | ~70 dBA |
| Weight | 14.4 lbs | 7.5 lbs | 8.3 lbs |
| Bag Capacity | 3.88 qt | ~2 qt (est.) | ~1.5 qt (est.) |
| Tool Variety | 4 tools | 3 tools | 4 tools |
| Best For | Homes, offices, classrooms | Small apartments, light home use | Spot cleaning, cars, light commercial |
Relative to the Bissell Zing, the Sanitaire has a higher capacity and quieter operation, but at a heavier overall weight. Against the Hoover PortaPOWER, it delivers stronger suction and larger dust storage, but trades away some portability.
User Sentiment: Trends from Real Customers
Real-world use cases highlight excellent overall performance and low noise. An estimated 80% of reviews comment positively on cleaning flexibility, with particular praise for long cord, hose, and above-floor reach.
- Positive: “Cleans my entire office without unplugging.”
- Positive: “Quiet enough to use during work hours.”
- Mixed: “Heavier than expected, but the cleaning power is worth it.”
A recurring theme: the sound output is an immediate improvement over older upright or bagless models, though portability may not satisfy all users.
Who Stands to Benefit Most (and Who May Not)
- Ideal for users needing strong suction with low noise—think offices, classrooms, home nurseries.
- Recommended for those with varied flooring: hard surface, low-pile and moderate carpet.
- Suitable for users who dislike frequent bag changes.
- Good match for people able to handle 14+ lbs. when maneuvering the unit.
- Not the best for users prioritizing ultra-lightweight, highly portable options.
Price and Value Considerations for the SC3700A
The Sanitaire SC3700A is positioned at the upper end of mid-range commercial canisters, with an MSRP around $379 (est.) and real-world sales frequently trending $60–$80 below list, per Keepa price history (when available).
Savvy buyers may find the best value when the price dips below $320 (est.), particularly during promotional events. Sanitaire vacuums are known for reliability, so the up-front cost buys several years of low-maintenance operation.

Final Assessment: Sanitaire SC3700A’s Strength is Quiet Power and Versatility
For cleaning professionals and households seeking strong, quiet cleaning in a canister vacuum, the Sanitaire SC3700A delivers robust suction, long reach, and versatility for diverse surfaces. Its quiet operation distinguishes it for use in sensitive or noise-aware environments.
The main tradeoff is a heavier build than ultra-compact models, but the extended run time per bag and comprehensive tool set justify the choice for users valuing performance and reliability over portability.
Consider this vacuum if quiet operation, fine filtration, and all-surface capability are top priorities. For lighter, highly mobile cleaning, alternatives may suit better, but few models in this price range balance silence and power as deftly as the SC3700A.
