This is the old version. Here is the new version: sears.com/kenmore-10-000-btu-portable-air-conditioner/p-A020306742
Here is the owners manual for the new model: i.sears.com/s/d/pdf/mp-tc/10169941/prod_19327132112
The exhaust hose is included: "The length of the exhaust hose can be extended to 59 inches, but it is best to keep the length to a minimum. Make sure that the hose does not have any sharp bends. Do not use extension tubes or replace the supplied exhaust hose with a different hose, or a malfunction may result. There must be no obstructions within the hose, or the unit may overheat."
To see all parts that are included, go to Page 6 of the owners manual.
