What’s actually different
Super convection. The BOV900BSS’s 2-speed fan adds extra airflow control specifically tuned for air frying and dehydrating, which Breville states reduces cooking time by up to 30%. The BOV860BSS uses standard convection without the added fan-speed control.
Shared Element iQ heating. Both use the same 5-independent-quartz-element system for even temperature distribution — this part of the cooking experience doesn’t change between the two.
Price. The BOV900BSS costs more, reflecting the added convection technology.
Who should buy which
Buy the BOV860BSS if you want strong air-fry performance and 11 functions without paying flagship pricing.
Buy the BOV900BSS if you specifically want the fastest, most controlled air-fry and dehydrate performance Breville offers.
Frequently asked questions
Is the BOV900BSS’s speed advantage noticeable in everyday cooking? Breville states up to 30% faster cooking with super convection; the practical difference depends on the specific food and batch size.
Do both have the same capacity? Check current listings for exact interior dimensions, as capacity can vary between tiers even when the core technology is shared.
Is the BOV900BSS worth it over the BOV860BSS for basic air frying? For basic jobs, the difference is smaller; the BOV900BSS’s advantage shows most in dehydrating and high-heat crisping where the 2-speed fan matters.
