Thanks OP! purchased.

I ordered 1 a few days ago. Going good so far. As mentioned above, yes it does leave streaks sometimes, but that depends on how much pressure you apply and the angle at which you are holding it when using. If you use it right, its fine.
Also just registered the product (leaflet inside the box).

Go to wintecs window cleaning supplies, buy squeegee handle then channel at desired length get the rubber to match with a little overhang would recommend pulex ( get your self a couple of rubbers once they've worn just turn around ), also buy 2 scrims 1 to mop up 1 to dry, and to clean the Windows don't waste money on spray bottle stuff much better with a wet rag and a drop of fairy. Tip: don't clean in sunlight it will drive you mad.

Got this 2 days ago and sold it already bloody rubbish, especially if you have deep window sills. I'm a window cleaner and went over the windows with a proper squeegee much better job and half the price with no charging. Just go for the squeegee and a cloth to wipe the sill after.

Anyone know the difference between this and the wv60 that Tesco have for £29?

Dreadful device once used need to still clean and dry remains from the window.

Great device. I really can't work out HUKD in terms of ratings! This was posted at £29 at Tesco for the Premium pack a few days ago and is receiving heat for the base unit for £34 alone. No offence OP :-)

Yes, that's what I thought about the grammer...great device though

Great for sucking all the water off tiles and shower screen etc so it doesn't dry leaving scum stains.

same price at tesco

same price in tesco if anyone interested

Problem with these in my experience is actually with the user. They seem to think that throwing water at a window then immediately using this to clear and clean the dirt away, expecting it will result in it being crystal clear. The windows still need cleaning first, this device is for the final cleanup. I've been using mine now for over 4 years on windows, tiles and a conservatory and yet to experience the dreaded streaky finish people go on about. It is also way quicker than how I used to have to do it with multiple cloths and squeegee blade.

Amazon ONLY do a manufacturer 12 month warranty, John Lewis is 2 years, no brainer, go for the extra years warranty and from someone who pays tax in the UK....

Been using mine for a couple of years now and overall they are pretty good(though not perfect)!
Streak free they are not though!
Once charged I can do my windows and my next door neighbours (who is 95 now bless her).
Results seem to be better using hot water and fairy liquid!

Yet another device that puts the working classes out of a job.

Fantastic device, use it for cleaning windows, clean the shower, cannot rate this appliance more highly. Had one for years and would not hesitate to buy another!
