Bosch has launched two new cordless stick vacuums: the Unlimited 9 and the Unlimited 10. Both models are positioned as premium, whole-home cordless options designed for carpets and hard floors, with an emphasis on fine dust pickup, allergy-friendly filtration, and less messy bin emptying. Both the Bosch Unlimited 9 and Unlimited 10 can be purchased with either a standard charger, or with an upgraded “Fast Charging” charger. The accessories included vary depending on whether the model includes a fast-charging upgrade.

Bosch MicroClean Technology and the MicroClean Ring
A headline feature shared between both releases is Bosch’s MicroClean Technology, which includes a MicroClean Ring, a light that is designed to help users confirm when floors are “really clean,” not just visibly clean. Bosch says the ring illuminates to indicate when particles are no longer detected on the surface.
Bosch also claims the MicroClean Brush can pick up extremely fine debris down to 0.3 microns, with >99.9% dust pickup performance under its stated test conditions.
HEPA Filtration for Allergy-Friendly Cleaning
Both the Unlimited 9 and Unlimited 10 include HEPA filtration, aimed at households concerned about allergens and fine dust. Bosch states that over 99.99% of dust particles, including allergens, are filtered and prevented from being released back into the room during cleaning.
Dust Compression Slider for Less Frequent Emptying
Bosch is also emphasizing convenience with a dust box compression slider, included on both models. The company says the compression slider packs debris inside the bin to help reduce dust clouds while emptying and allows users to empty the vacuum up to 50% less frequently.
Unlimited 9 vs Unlimited 10: What’s the Difference?
While both vacuums share Bosch’s MicroClean system, HEPA filtration, anti-hair tangling design, and dust compression bin, the Unlimited 10 is positioned as the more feature-rich option. The Unlimited 10 upgrades with:
- longer rated runtime
- a larger battery
- a more advanced display
- additional cleaning modes
- a bendable flex tube designed for cleaning under furniture.
Meanwhile, the Unlimited 9 may appeal to shoppers who want Bosch’s core features at a lower price point, with a simpler interface and fewer modes.
