steam cleaning oven


We need to buy a new oven and most of the ovens that we are seeing no longer have a ‘traditional’ cleaning cycle where the temperature would rise for around 3 hours.  What we are seeing now is called “Steam Clean” which is defined as “A steam cleaning option cleans the oven cavity in a 30 minute cycle with less odor and heat.  Is this acceptable especially for pre-pessach kashering?

thank you for your time,
