Onson

Onson manufactures both cordless upright and robot vacuums from its Shenzhen base, giving the brand hands-on experience across product lines. Their robot models offer app-controlled suction levels that let you dial in the perfect power for hardwood without over-aggressive brush action.

Suits budget-conscious buyers who want manual control over suction and app scheduling. Onson's cordless lineup also makes sense if you're building a multi-tool cleaning strategy beyond the robot alone.
