Samsung Series 5 Optimal Dry DV80CGC0B0AEEU 8KG Smart Heat Pump Tumble Dryer - White vs Series 6 Optimal Dry DV90T5240AN 9KG Smart Heat Pump Tumble Dryer - Graphite — Comparison

The Samsung Series 5 Optimal Dry DV80CGC0B0AEEU in white and the Samsung Series 6 Optimal Dry DV90T5240AN in graphite are both heat pump tumble dryers at £499, with sensor drying and SmartThings connectivity. The main differences are capacity and efficiency: the Series 5 takes 8kg and is rated A++ at an annual consumption of 235, while the Series 6 takes 9kg and is rated A+++ at 194.

The Series 6 is also a little quieter at 63dB against 65dB, has a half-load option and a filter-full indicator, and weighs 50kg against 52kg. Its cycle times are longer, with 220 minutes for a full load against 190 minutes on the Series 5. Neither model includes a vent hose, and the Series 6 lists a rear venting position while the Series 5 lists none.

Buyers of both models describe them as quiet, efficient and easy to use, and several say the cycle stops when the load is dry. Common complaints are that cycles run longer than expected, which is typical of heat pumps, and that the Wi-Fi features are unnecessary for some owners. One Series 6 buyer found the sensor sometimes runs on after clothes are already dry and that the delay start was hard to work out.

Bottom line: choose the Series 5 in white if an 8kg drum is enough and A++ efficiency suits you, and choose the Series 6 in graphite if you dry 9kg loads and want the A+++ rating, the half-load option and the quieter running.
