Pricy but no regrets
I have been using the vacuum/mop for a few weeks now and I love it. I have tilled flloors throughout, with large rugs and two carpeted bedrooms. The vacuum copes with it all. It is really easy to change from vacuum to mop and I use the mop section every day in the kitchen after I have vacuumed, it's so easy and the floor drys really quickly. This is pricy but for me worth every penny. I rinse through the mop pads after I use them ( five minutes) leave them to dry and they are ready for next time. The battery life has never been an issue for me. The changing of the dust box from top to bottom can be a little tricky for me as I have inflammatory arthritis in my hands and have better/worse days. But overall this is still easier than the bucket and mop scenarios. A happy customer.

Reliable equipment I would recommend.
The Triflex HX3 is great bit of kit for the home. It's quiet , compact and efficient. With its 3 in 1 hoover design you can hoover almost every where. The mopping facility I find easy to use and the pads wash in the washing machine.
