The recirculated air usually passes through high-efficiency particulate (HEPA) filters before delivery into the cabin.
Perhaps most important, iRobot added new models at higher prices with features like a HEPA filter, scheduling and room-by-room navigation.

To minimize the risk of disease spread by aircraft, regulations requiring HEPA filters for any aircraft that uses recirculated air should be seriously considered.
Vacuums with HEPA filters prevent dust from escaping as you clean.
High Efficiency Particulate Air (HEPA) filters, which usually last a year.
Plastic mattress covers help keep dander out of beds, and room air cleaners equipped with high efficiency particulate air (HEPA) filters can remove dander from the air.
Vacuuming tends to stir up allergens without necessarily removing them, and can actually increase the number of airborne allergens, even when newer vacuums containing HEPA filters are used.
The stainless steel enclosure houses the same 1, 400-watt DC brushless motor as the previous models, dispersing HEPA-filtered "sheets" of air through a single laser-cut slit in each of two wings that extend from the Tap's sides.
It scrapes away (rather than evaporates) water using two jets of HEPA-filtered air that reach top speeds of 430 mph and are powered by a proprietary motor that accelerates from a dead stop to 95, 000 rpm in 0.7 second flat.
