Is there any brush you can clean slide out from ground ?

Have a look in the paint dept. Extending pole, much better than the stuff RV suppliers have, & adjustable brush holder that fits it for reaching high places.

Is there any reason why you cannot use a ladder or, better still, get up on the roof & wash from up there? The roof is as stable as the floor inside.

Some of us old folks couldn't get on the roof if we tried, let alone "should", whether we can or not. X2 for that kind of a tool but haven't found one yet.
