Steam in one basket: plan a dual-basket meal
A steam function can change how you plan a dual-basket meal, but it does not necessarily make every basket a steamer. Check which drawer gets water, which modes it supports, and what you will need to clean afterward.
Ask where steam is available, not just whether it exists
The Philips 5000 Series NA555/00 shows why that distinction matters. Its 9.6-quart total is split between a 6.3-quart large basket and a 3.2-quart small basket. Both can air-fry; only the large drawer can steam or combine steam with air-frying. If you want to steam a main dish while air-frying a smaller side, its separate basket controls and synchronized-finish function can accommodate that plan. If both foods need steam, the machine does not fit the request.
Compare the use case, not just total capacity. A requirement for two different temperatures can be satisfied by many dual-basket fryers. A requirement for steam plus a crisp side narrows the field to models that document both functions at once. The NA555/00 review describes the precise operating plan; the COSORI CAF-R901-AUS is a comparison point for two separately removable air-fry baskets without the same documented steam system.
Plan the water and the vent
Steam means filling the removable tank to, but not over, the marked maximum. The NA55X manual gives about 800 ml and instructs the owner to empty it after each cooking cycle. It also says to keep the rear outlet away from a wall and receptacle: the manual recommends about 20 cm from the wall, while other safety text gives side and top clearances. Choose a position with airflow and room for hot steam before deciding the appliance will fit under a cabinet.
Think about the end of the cook as well as the start. The large basket's steam-clean program runs for 15 minutes, then switches to a five-minute drying stage. You still need to rinse the basket, empty the tank, and wipe away loosened grease. The appliance asks for descaling after 10 hours of steam operation; the manual warns against vinegar and other acidic descaling liquids. If you will use steam often, this maintenance is part of the routine rather than a rare exception.
Choose a simpler dual basket if that is what you need
If most of your meals need two air-fried foods with different settings, a conventional dual drawer may be a better fit: you avoid the reservoir and descaling tasks. If your main goal is steaming one basket and air-frying the other, look at the basket-specific limits and synchronization behavior. In the Philips example, the operating manual describes independent pan settings and a synchronized finish, while Philips's HomeID app provides recipes rather than remote fryer control.
Also separate feature questions from electrical questions. Philips's U.S. technical table for NA555/00 lists 120 V and 2,750 W, while Philips country pages for the same model code publish 220–240 V at 2,750 W. The linked manual tells owners to verify the type plate but does not settle the U.S. unit's rating. If 120 V / 60 Hz documentation is essential, do not treat the NA555/00 as a confirmed match until Philips resolves the exact unit's label.
Use the finder to distinguish a steam-capable basket from two steam-capable baskets, then compare the Philips NA555/00 review with the model that better matches your portion size and cleanup tolerance.
