115 Volt electric Pumps V 12V

Just a question to all you guys that have been at this for a while.
Any reason not to use 115v pumps running from the mains electric rather than a battery.
I have been using my fatboy for both roof and siding and find the battery does not always last.
Does anyone run a bigger electric pump to get more distance direct from property electric or a generator.

Any thoughts

Bill

I charge my fatboy battery off my PW skid. When in the shop I use a battery tender to keep it charged.

I seem to remember that John T used electric pump but I don’t have enough Posts to send him a PM.
Anyone know if he is still active on the forum.
