Large spare drinks bottle for having a pee at side door of van.I go at least twice in the day while working.
Never lift reel in and out.have it fixed in the van.much easier on your back.
Use a very high flow for most work.you'll work quicker and save at least 30 mins a day.
Always have business cards on you at all times while working (same for 'windows cleaned today'tickets/invoices)
End of day jobs include water production, charging battery,etc Don't forget to always check your tds in tank too after purifying.
Spray bottle with detergent for trad jobs.saves getting the bucket out.leave it in the van with a lid on.just use it for a quick dunk of your T mop here and there.
Always have a good stock of spares in the van(Connectors,tape,blades,rubbers,brushes,gooseneck's, etc,etc)
