The main reason that you want the water and the hose is so you can test your gutter system. Once you think you have all the debris cleared out of the gutter, you need to test it to make sure that you do not have any more clogs, especially in the downspouts. Start at one end of your gutter system and start running water. Check to make sure that the slope of your gutters is steep enough so that no pools of water form. You want constant movement toward the downspout with no accumulation. The next thing you will check for is that the water flow continues out the bottom of the downspout at the same rate that it is going in. If the water only trickles out or stops coming out all together, then you know you have a clog somewhere.

If you do have the spray nozzle, your hose can be an even bigger help when it comes to cleaning you gutters. You can use the hose to dislodge debris and clogs. A regular garden hose under normal household pressure and a jet setting on your nozzle will have enough force to loosen almost any leaf clog in your gutters. You can also use the water to clear the gutter system of debris. Use the water stream to lift and throw the leaves and twigs out of your gutters. Then once the big stuff is gone you can use the pressure of your hose to clean off the mildew and muck that forms on the bottom of the gutter trough. Because gutters are usually made of aluminum or other lightweight materials, you cannot use a pressure washer to clean them as you would siding or other surfaces. The pressure from your hose is perfect.

You need to be careful when using your hose to clean your gutters though. Handling the hose up on a ladder can be tricky and you need to make sure that you always keep at least one hand on the ladder and do not lean. Make sure that the dangling hose is not caught on your feet or in your way when you are climbing up and down. A technique that I use is to tie the hose nozzle to my belt while I climb and make sure the hose stays on the outside of the ladder. Another safety precaution to keep in mind is that your ladder rungs will get slippery when they get wet. Anytime you bring water into the equation, the danger level of any home improvement task goes up. Be extra careful of your footing and hang on tight when climbing down a wet ladder.

When you climb up the ladder and can reach your gutters the next step is to remove the debris causing your blockages. To do this you will need a pair of gloves. I suppose the gloves are not mandatory, but I do not know many people who want to handle moldy leaves without protection. I usually just proceed by scooping out the mess with my hands, but some people prefer to use a gutter cleaning tool such as a gutter scoop to do this job. If you want a tool, you can purchase a small trowel or even gutter scoops of various sizes at your local Lowes or Home Depot. Just make sure that the size of the gutter scoop matches the size of your gutters. Once you remove the refuse from the gutters, you can throw it on the ground or into a garbage bag. If you chose to throw it on the ground, you will only have to go around and collect it in a garbage bag later so I recommend disposing of the debris as you go. If you do the same, make sure you attach the garbage bag to the ladder so that you have both hands free to continue working.

You will have to move the ladder from section to section so that you can clean out all the debris. The alternative is to use long handle gutter cleaning tools. A gutter cleaning wand allows you to clean sections of your gutter that are out of your normal reach. An alternative to doing this part of your cleaning by hand is to purchase a gutter cleaning robot. iRobot makes a gutter cleaning machine they call the iRobot Looj. This contraption sits inside your gutter and propels itself along while it blasts away leaves and debris. You will only have to move the ladder once from the starting point to the end. Of course, gutter cleaning robots do not clean the vertical part of your gutter system or the downspouts, but they convenient for the rest of your gutter cleaning.

After you make sure you have all of the large pieces of mess out of the gutters you will need to make sure the downspouts are clean. The easiest way to do this is to put a garden hose into the opening. The running water will force any debris down the spout and out the bottom where you can collect it into a garbage bag. Next, some people like to use a leaf blower to blow out any smaller pieces that you did not get out by hand. I find handling a large piece of equipment like that on ladder too hard so I usually skip this step. The final step is to rinse the entire gutter system with your garden hose.

As you can see, you probably have everything you need to clean your gutters within easy reach. To summarize, you must have a ladder, gloves, garbage bags, and a hose to clean your gutters. Optional pieces of equipment include a small trowel or gutter scoop and a leaf blower.
