A clothes treating apparatus is provided that may include an accommodation chamber, in which an object may be accommodated; a first heat pump cycle having a first evaporator, a first compressor, a first condenser, and a first expansion valve; a second heat pump cycle having a second evaporator, a second compressor, a second condenser, and a second expansion valve, and arranged such that air introduced into the accommodation chamber passes through the first evaporator, the second evaporator, the second condenser and the first condenser, sequentially; and a controller configured to control an operation of the first and second heat pump cycles. At least one of the first compressor or the second compressor may be provided with an inverter that changes a drive speed of the compressor through a frequency conversion. The controller may drive the at least one of the first compressor or the second compressor within a predetermined drive range, by controlling the drive speed of the at least one of the first compressor or the second compressor using the inverter.
