Those two are the Tineco's premium with more power and smart sensors that make battery life more efficient and are made for bigger homes.

Both cleaners have a standing charging dock and a foldable tube. Cleaning mechanics are similar; however, the newer A90S has some extras on par with more power and longer battery life.

Tineco's Best Cordless

Key features:

  • Senses dusty areas, edges, and floor type
  • Advanced clogless system
  • Upgraded sealed filtration
  • App integration
  • The biggest battery
  • More power

Performance upgrades:

  1. More power
  2. New Master Brush senses dusty areas, floor type, and edges (boosts power).
  3. The switch opens a suction inlet to let large debris be sucked out.
  4. Upgraded HEPA filtration is now safer for everyone.

The cleaner folds to reach under furniture, runs for almost 2 hours, and has lots of power for carpet cleaning.

Upgraded clogless system opens gates for wider intake and picks up large debris. It has two cleaning modes: for deep cleaning and for large particles.

The biggest upgrade over the other generations is the floor detection that comes with the newest head.

Even tho both models have the same LED angle, the A90S head seems to illuminate a larger area.

Efficient, smart, powerful

Tineco's best S series

The S70 has a Clogless system that helps pick up large debris.

3D SensePro technology:

  • DustSense
  • Edge Sense
  • Light Sense
  • Clogless system

With 3D SensePro the cleaner is more efficient and has a higher pickup score

Unlike the A90S, the S70 does not sense floor type and has a different cleaning head.

The clogless system doesn't have a switch to open the inlet wider.

The ZeroTangle brush is made for not switching heads between hard floors and carpets. It is ideal for deep cleaning and surface pick up.

A cheaper alternative to the best

Summing up

The PURE ONE A90S is a clear winner with more power, a newer head, and an efficient battery.

However, if you don't need those extras and want a vacuum for hard floors and quick cleanups. Or you have an upright and are looking for a cordless helper, the PURE ONE S70 is a great buy.
