Answer: Turn the Roomba upside down, and locate the side-sweeper: a circular, three-pronged plastic piece at the top left of your Roomba. Using your Phillips screwdriver, remove the single screw that holds the side-sweeper in place, and remove the side-sweeper. Using your hands or your crevice tool, clean off any hair/debris that is attached to the side-sweeper and the place where the side-sweeper attaches. The front wheel--positioned front and center on the bottom of your Roomba--should easily pop out. Use your hands to remove any hair or string attached to the wheel itself. Then use your vacuum with the crevice tool to vacuum the opening where the wheel goes. On the bottom of your Roomba, you will notice a rectangular flap, that should lift open. Under this flap, you'll find your cylindrical brush, which is likely to be very dirty. Lift out this brush. On either end of your brush there will be small bearings. (On many models, these bearings are yellow). Remove these bearings and set them aside. Then, using your hand, pull off any hair that has gotten tangled around the ends of your brush. Take out the iRobot Roomba bristle brush and slide it onto the end of your cylindrical brush. Pull the bristle brush down the length of your cylindrical brush in order to remove hair and debris. Remove the hair/debris from the bristle brush with your fingers, and repeat this process 2-3 more times. An iRobot Roomba bristle brush should have been included with your Roomba. If you have misplaced this item, you can purchase one online for around $5. Below the the space that held the cylindrical brush, you will see a cylindrical rubber roller. This will slide out. Remove the (yellow) bearings, and pull off any dirt/hair from the ends. Using the brush attachment on your vacuum, go over all sides of the brush and roller to remove dust, dirt, and hair. Set the brush and roller aside, and switch to your crevice tool. Now vacuum the compartment where the brush and roller go, paying careful attention to the gray flap that seals the compartment.

Problem: Write an article based on this summary: Simmer a pot of water in beef bones. Replace the beef bones with the beef ingredients. Throw charred onions and ginger into the mix. Boil rice noodles. Add vegetables. Top with spices.

Answer: Beef bones are where you'll get the distinctive broth taste. It's recommended that you let the broth simmer for 3 hours with the beef bones in the soup. From there, the bones should have left their flavour in the broth, and you can replace the bones with the edible beef ingredients. Add salt to your pot to get a more striking taste. Your beef parts should be added three hours after you first put the bones in the broth. From there, the soup should be left to simmer for an additional 3 hours. It's recommended you take out the bones before adding the rest as it can be difficult to extract the bones once the pot is filled. Onions and ginger help to give the pho that pleasant smokiness. Charred onions have the best effect. Take a pair of tongs and use them to hold onions over a gas-powered stove. From there, chop them up into thin slices and add them to the pho. You will definitely notice the improvement to your broth. Depending on how much you want the charred onions to inform the broth's taste, you can either add them early on with the beef ingredients, or you can serve it after adding the noodles as a garnish. For the sake of smokiness, it's recommended you add them with the beef. In a separate saucepan, bring water to a boil. From there, take a handful of rice noodles and throw them in. Depending on the thickness of the noodles you're using, it can take up to five minutes for the noodles to properly cook. Once the noodles are sufficiently soft, strain them out of the second saucepan and add them to your main pho pot. To preserve their form, it's recommended you try blanching the noodles, taking them quickly from boiling to cold water as a way to quickly halt the cooking process. Let the dry noodles into a boil for 10-20 seconds until they have lost their stiffness, then immediately put them under cold water. This will ensure they are cooked properly, but will stop the cooking before they get soggy. If you're making your own pho, you can practically add whatever vegetables you like into the broth. Because vegetables tamper with the broth's flavour, they should be steamed and added to the broth after it's finished cooking. Carrots and broccoli are most recommended, as they're spoon-sized and compliment the taste of the broth. Carrots are best cut into coin-thin slices so that they best soak up the flavour of the soup. Get the vegetables to a soft tenderness before adding. They will get softer still once added to the hot broth. The texture shouldn't be resistant to the teeth at all, but the vegetables should retain enough strength to keep their form. A great cook always tries to make his dish great on the eyes as much as the taste buds. Aromatic spices help improve the taste of the pho, but they're also great for adding that visual touch once the basics have been taken care of. Sprinkle cilantro and green onion atop your soup once the broth and main ingredients are ready for eating. Prepackaged pho spice blends are available, but they aren't recommended if you want the best-tasting pho.
