No . Not a container, it has a siphon tube that draws directly from your supplied container ..IE gallon , quart, 5 gallon container.

Does the 4200 psi model have an adjustable cat pump and chemical hose attachment?

Hello! Yes, this model has an adjustable cat pump and chemical hose attachment. Thanks.

do this take a oil filter?

I have a slightly different model, but no oil filter. Just change the oil regularly. Dump out on one side. Put same amount back in. Honda commercial engines are bullet proof!
