Series 6 is the better buy for most households: a 9kg front loader with a 1400rpm spin and a five-star energy rating for around $1,450. Series 8 adds a kilo of capacity, automatic detergent dosing, Wi-Fi and a lower running cost, but costs around $750 more, which takes a long time to earn back on power.
Both machines wash the same way. Same 1400rpm maximum spin, same cold-fill-only connection, same AquaStop leak protection, same two-year warranty and the same 598mm cabinet width.
Bosch Series 6
Nine kilos, 1400rpm, five energy stars, 4.5 water stars and 78 litres on the test cycle. It has a reload function that lets you add a forgotten sock after the cycle starts, Super Quick 15 and 30-minute programs, and an automatic stain-removal system. Owners rate it 5 stars from a small pool at The Good Guys.
No Wi-Fi, no auto dosing, and at 590mm deep it is the shallowest of the two, which helps in a narrow laundry.
What We Like:
- Reload mid-cycle
- Five energy stars
- 590mm deep
What We Don't Like:
- No Wi-Fi or auto dosing
Bosch Series 8
Ten kilos, 5.5 energy stars, five water stars, 72 litres on the test cycle and 181kWh a year against the Series 6's 215. It adds i-Dos automatic dosing, which measures detergent per load, a touch display, Home Connect over Wi-Fi and a load sensor. There are no owner reviews at The Good Guys yet.
It is 633mm deep, 43mm more than the Series 6, and the door opening needs 1,074mm of clearance.
What We Like:
- Automatic detergent dosing
- 181kWh a year, 72 litres a cycle
- 10kg drum
What We Don't Like:
- 633mm deep, wide door swing

Owner ratings are from The Good Guys. Energy and water figures are the registered Australian label values on the same test program, so they compare directly.
What actually differs
Running cost. 181kWh against 215kWh is about 34kWh a year, or roughly $11 at 32 cents a kilowatt hour. Six litres a cycle is about 1,500 litres a year. Real, but not $750 of real.
Auto dosing. i-Dos holds detergent in a reservoir and measures a dose per load. Owners who use it report using noticeably less detergent than they did by eye, which is where the ongoing saving actually comes from.
Capacity. Nine kilos against ten. A 9kg drum handles a queen doona; 10kg handles a king. If doonas are the reason you are shopping, that is the difference.
Depth. The Series 8 is 633mm deep. In a laundry cupboard with a door, measure before you buy.
What doesn't change: spin speed, cold-only fill, drum material, warranty and the fact that neither has a hot water connection, so both heat their own water.
FAQs
Does the Series 8 wash cleaner than the Series 6?
No. Both use the same drum and wash system. The Series 8's advantage is dosing accuracy, capacity and running cost, not wash quality.
Are these machines cold-fill only?
Yes, both. Bosch front loaders in Australia take a cold connection and heat water internally, which is why their energy figures include heating.
Which is quieter?
Bosch does not publish a decibel figure for either on the Australian listings. Owner reviews of both describe them as quiet on wash and typical for a 1400rpm machine on spin.
