Collection: Upright Vacuums

Within the Sandia line, the Force 14 stands out as a high‑quality upright for commercial use thanks to its 12‑amp motor, 74.8″ of vacuum lift, and dual‑motor system for suction + brush agitation.

Look at these key specs with Sandia as an example: Suction lift (e.g., 74.8″ for the Force 14) Mojave Supply +1 Motor amps (12 A in Sandia’s case) and brush RPM (4000 RPM for Force 14) Shine Shark Solutions +1 Cleaning path width (14‑inch for Force 14) Shine Shark Solutions +1 Height adjustment/floor type compatibility (4‑position carpet height adjustment) Cleaning Supply USA Filtration quality, build durability, ease of maintenance (Sandia emphasizes modular design)

For commercial uprights like the Sandia, something like 74.8 inches of vacuum lift is a very strong indicator of good suction.

If you are considering reliability in the commercial upright category, Sandia has a strong reputation: users cite modular design for easy maintenance, commercial‑grade motors and parts, and good customer service for parts. For example, one review states:

In the context of an upright commercial machine, the Sandia Force 14 comes very close: dual motors, strong suction, high brush speed, commercial filtration, and ease of maintenance. It may not be “perfect” in every scenario (e.g., cordless convenience, small‑apartment specialization) but for heavy duty upright use it is among top.

There’s no universally confirmed “number one best‑selling vacuum” brand globally, but several sources indicate that Bissell is the number one manufacturer of floor care products in North America by sales.
