Err...It was 88ft 2 inches at Sheffield.
"Tickling the glass" is as good  it gets at that height so you may need to  allow for a double scrub with "Iso" added.
Richy you will need good experience at 50 foot plus before you go to 7 storeys, 7x10ft= 70ft but if its a big job you may get that as you go upwards. The pole wont fall away from the building but you may need two anchor men to hold a couple of safety lines to stop sideways slip. You may need to look at closing the road.
The advantage of being able to do it is you get the rest of the building.
A 70ft pole will cost you Approx £500 min.

whats "Iso" jeff?

Isopropyl alchohol is another solvent cleaner you can add to wfp water that doesnt leave a residue cause it evaporates - jus like that

thanks Jeff.  how can you be sure even with iso that a first clean by wfp even on a second storey has been effective? is it just a question of practice makes perfect?

You say its a main road, how busy is it on a sunday or after 6pm or before 7am?

Also look at the width of the pavement, some can be 15' to 20' wide.

If you are going to use a cherry picker, you will still need to create a safe working area around it.

Check with the local highways department,about closing just one lane instead of the whole road.

You will need to practice at working at 50' plus before you attempt 70'.

You also have to clean like an escaulator, do not try to move the pole sideways at that height.

Also do not work to close to the building, step back and use gravity on the brush head to created srubbing friction on the glass.
