Yes, but not very well. The small pump within a pressure washer is designed to PUSH water, not pull it- and the rate of flow is very small. It would pump a long time to move a major amount of water. The pump will also not handle dirty water very well.
If it has no pressure your problem should be on the pump. The three things I'd recommend you to check are: Packings, Unloader and Valve Kit.

The washer tank may be empty, or the pump not working.
