Summary: Great for outside windows but if you use inside its difficult to reach the bottom of windows. If you turn on its side (ie horizontal) then it spurts water out of the air vent, can't be doing the motor much good. Battery capacity quite low, needs a recharge after half a dozen medium sized windows. The rubber stopper for the water compartment has pulled out of its retainer and I can't push it back in (still goes into the bung hole). However what it does it does very well.
Summary: Saw this product advertised on a shopping channel but Screwfix sold it at a better price. It did a good but not great job of cleaning my house windows. It tended to leave a few streaks but the windows were quite dirty even after washing them over so this may improve as the next time its used the windows won't be so dirty. These streaks were very thin lines though and not hardly noticeable.
Summary: Got this because I have a fair number of larger windows and for screens of the car. So far so good, clean is very good and the suction drying saves a lot of time. I would recommend. Don't know how long it will last but it will probably pay for itself in time saving in under a year. I suspect the blade will be the first ting to go, but that is a detatchable component so, replaceable.
Summary: " We suffer from bad condensation on our windows during the cold months and go through lots off kitchen roll drying them off. Not any more, the window vac dries the windows in minutes with no more soggy paper towels to get rid of. We also use it to dry off the shower and the humidity levels in our house have fallen. The blade was a bit big for our narrow windows so we invested in the shorter blade. Very happy with this purchase.
Summary: The Karcher window cleaner works really well on grubby windows removing most marks with ease and leaving a smear free finish. Its very easy to use. It won't remove stubborn marks but then I wouldn't expect it to. It is also very useful for removing condensation which also leaves the window clean and fresh looking. Overall a very useful tool and not bad value either.
Summary: " This is an excellent product but it's unlikely you'll be able to do all your windows on one charge and a re-charge takes 2 hours. That's a shame because the design is good, it's easy to use and it leaves a streak free window. I suggest you make your own cleaning solution with a tablespoon of vinegar and a few drops of washing up liquid in half a bucket of water.
