Overall I recommend this vacuum cleaner
After having a Dyson and then a Shark upright vacuum cleaner and finding them heavy and cumbersome we decided to look at cordless ones. The research showed that the power didn't last long on maximum and the consumer reviews weren't encouraging.
We decided on the C3 after watching many reviews and are pleased with the purchase .
Our only complaint is the amount of different heads , and which does what etc.. we only have 2 rooms that have carpet , the rest of the property is wood with rugs .
The standard head is fine for this , but I think eventually we will purchase a rotary brush head for the rooms fully carpeted.
Overall, we're happy with the purchase.
