I prefer cordless, the rest of the old geezers like Mikey, Chavez and Marty like corded..... I think it's more of a generational thing... Think of the cordless phone, as long as you remember to charge it, they're fine... When your (techs) don't charge or forget, that fooks everyone up... More to go wrong with a battery sprayer in their eyes...
MultiSprayer or FlexiPro both last at least 1 hour of spraying or 60 gallons I believe... When you pre spray, you probably use it 5 mins per job... Spray-turn off-spray-turn off... Batteries go bad in a few years, not hard unless you got all thumbs... I have both the MS and FP.. I got the FP 8 years ago and changed 2 batteries, just got the MS and it seems nicer but holds .5 gallons less product... Nicer twist lock charging port, nice wand holder, and slimmer design but only comes with a cigarette charger, you need to buy a wall plug adaptor... FP is bigger, has wheels, telescoping handle, comes with both wall and car chargers, but with the wand/lance holder sucks as it goes internally and can corrode the aluminum base plate and the charging port on the back..
I still use my FP daily as it holds more and has wheels... My MS for applying protection only...
I have the WORX sprayer is decent, but wouldn't use it as a main everyday sprayer... I don't have a ISP sprayer...
