very hard to install the disk, had to use a screwdriver as a shoehorn to force it on. no instructions in box, but since it not my first cleaner I had a good idea how it should be put together no counter weights for the hose (recommended in the video) but I had some from old cleaners seems to work fine once I got it together my last (cheap) cleaner lasted for1-1/2 years. I run it for 5 hours every day. I only expect the same from this one.
