What is PureCyclone?
Powerfully separates air and dust to avoid pre-filter clogging and suction loss.
Budget yet Solid
Key features:
- Large dustbin
- Long battery life
- Adjusts suction on dusty areas & along the edges
- Auto illumination in the dark
- Tackles large debris
The PURE ONE A50S is the newest model in the series, with a lot of power, new sensors that detect edges, a long-lasting battery, and a new 120° wide-angle headlight, which we saw in the PURE ONE Station 5.
Compared to the A90S, the A50S lacks:
- power
- convenient storage
- battery life
- advanced filtration
- suction adjust on carpet
- app integration
Its foldable design allows reaching under furniture, and better filtration makes the cleaner safer for everyone.
Things that affect performance (versus the A90S):
- Older brushroll design (good but not as advanced)
- Doesn't save battery life on carpets (no iLoop)
With all the upgrades the A90S has, this one is a great value for what it does.
The best buy for the price
The A50S is an affordable alternative to the best A90S.
Tineco's Best Cordless
Upgrades over the A50S:
- More power
- Longer battery life
- New type of brush
- Upgraded display
- App integration
- ClogLess system
- Upgraded HEPA filtration
Unlike the A50S, which requires wall-handing, the A90S comes with a free-standing charging dock.
Sucks out large debris
Performance upgrades:
- More power for carpet cleaning.
- New Master Brush senses dusty areas, floor type, and edges (boosts power).
- The switch opens a suction inlet to let large debris be sucked out.
- 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.
Efficient, smart, powerful
Sum up
The best Tineco cordless: PURE ONE A90S
The most featured, lasting, and powerful in the lineup. However, the A50S is a great buy if you don't need the latest-gen extras.
