Water supply
Garden tap, bucket or tank: plan the water first
A pressure cleaner still needs an appropriate supply of water. Decide whether that supply will be a pressurized tap, a supported suction arrangement or a reservoir built into the cleaner.
A tap connection needs the right feed
A conventional garden-water connection supplies the inlet of the machine. The pump then feeds the working hose or wand. Check the exact instructions for inlet pressure, required flow, water temperature, hose dimensions and connections. A hose that screws onto the adapter can still be an unsuitable supply.
Keep the inlet and outlet roles distinct when comparing reach. The inlet hose brings water to the unit; the outlet hose lets the gun move away from it. A listing's longest hose number is not necessarily the distance you can work from the pump.
A bucket requires documented suction support
Do not assume every washer can draw from unpressurized water. Look for the maker's actual suction setup, including the appropriate hose, filter, priming procedure and permitted lift or water position. A hose adapter alone does not establish that ability.
A supported portable cleaner can make off-tap rinsing practical, but the container, hose and water quality become part of the arrangement. “Fresh water” should not be interpreted as permission to draw dirty or chemically treated water contrary to the instructions. Refill logistics matter too: the tool's convenient size does not make the water load disappear.
The DCPW550 North American instructions describe a suction hose with a filter and float for a clean container. That is a documented inlet arrangement, not a reason to assign suction support to another washer in the same brand.
A tank changes what you move
An included reservoir can keep the water and cleaner together. Before choosing it, think about filling, carrying, draining and cleaning the tank. Dry-unit weight is different from the weight you handle with water aboard.
Also check how water reaches the pump. A separate tank placed beside a machine is not automatically equivalent to an integrated reservoir or an approved suction arrangement. The supported inlet condition still needs to be met.
Calculate a planning estimate carefully
If a supported mode has a documented flow figure, dividing usable water volume by that flow gives a rough continuous-flow planning estimate. It is not a measured session duration. Trigger use, operating mode, residual water and refill time can change the practical result.
For a mobile job, plan where the clean water comes from and where dirty runoff goes. The surface and cleaning agent may also impose restrictions at the location. Portability is useful when the whole water routine is workable.
Tell the finder what water you have
Select a garden-water supply for a pressurized feed. Select a container or included tank when that is essential. Then combine it with power and cleaning task. The result should represent a supported arrangement you can assemble, rather than an attractive machine that needs a tap you will not have.
