The Sanitaire SC3700A is a commercial-grade canister vacuum designed for quiet operation and durability in noise-sensitive environments like offices or during daytime home cleaning. The motor is isolated within the housing to keep decibel levels between 68 and 70 dBA. The chassis is made of ABS plastic and features a simple, modular design that favors easy maintenance over consumer-focused features like cord rewinds.
Specifications include a 9-amp motor and an 11-inch cleaning path. The vacuum uses "Style MM" bags, which provide better dust retention than standard paper bags. To ensure the longest life for the unit, users should avoid over-extending the 20-foot power cord and check the friction-fit wands periodically to ensure they haven't developed minor air leaks at the joints.
- The lack of a cord rewind mechanism reduces the number of moving parts that can fail in a high-use environment.
- Large rear wheels and front castors provide a stable base that tracks well on low-pile carpets and hard floors.
- The sealed HEPA-ready filtration system is designed to maintain indoor air quality in professional settings.
The stock plastic wands can flex under heavy pressure, so for the most robust feel, some users choose to swap them for metal wands. For a residential-focused canister with more comfort features like a cord rewind and more agile steering, the Eureka Whirlwind is a lighter home-use alternative.
Commercial-grade reliability is a valuable option within the upright and canister vacuums selection for those who prioritize longevity.
