The advert stated that the unit can be connected direct to the hose, great I thought. What it didn't state was that once connected water would spray out of every connection and joint. I had to apply sealant to all the joints and water repellent silicone grease to the bushes, this slowed down the progression of water. I will have to try and tape the joints next in a final attempt to seal the unit, not quite the thing to do to a brand new product. The squeegee was supplied with a washer, the brush was not, this meant that the brush unscrewed itself cascading water downwards. The brush also seems too large for the unit, making it unmanageable at full length. Apart from that it's usable.
