Your Roomba Is Choking On Dirt. Here s How To Fix It.

Hario ceramic coffee dripper
Amazon This Japanese pour over dripper can be used with your mug for a single serving or placed above a large carafe for a big batch of several mugs of coffee if you've got company (or it's just one of those mornings).

Use a cotton swab, magic eraser or damp microfiber cloth to wipe the sensors free of grime. Specific points to target include cliff sensors (on the bottom of the robot), optical sensor lenses and laser turrets (both on a robot's top). 

Whenever possible, I brew double shots of espresso for all my test runs. I make sure to record the weight of the grounds I use, plus the weight of espresso for each shot I pull. This data, along with readings from a portable refractometer, allows me to calculate two important percentages: TDS (total dissolved solids) and extraction percentage.

To pull shots, I start with the suggested method outlined in a given machine's product manual. Usually that covers the amount of coffee grounds expected per shot, along with any guidelines regarding coarseness level. Likewise, I follow tamping instructions (light, medium or hard tamp) if the manual provides them.

Getty Images If you're especially worried about lead, one easy way to mitigate that risk is to simply run the tap water a few minutes before using it. The most dangerous amounts of lead accumulate when the water has been sitting in your home's pipes overnight, so if you flush that immediate water out, you'll be in better shape.

Although it's technically safe for consumption, you can easily find plenty of people who say that hard water wrecks their skin and hair, and that buying a shower filter alleviated acne, frizzy hair and even eye irritation. Even more people say that a shower filter helped with itchy and dull skin, and flaky scalps.

And just like any coffee brew, the ideal extraction percentage for espresso is a range between 18 and 22%. This yields a balanced cup, assuming you perform an even and efficient extraction of coffee compounds from your grounds (both flavor and caffeine).

You can pull away dust clogging the filter by hand. A better method is to clear the filter by using a handheld vacuum. This way you won't let dust escape into the air or back onto the floor.

$90 at Walmart How we test espresso machines
My evaluation process for espresso machines is similar to how I test standard drip coffee makers. First, I hand wash and dry all removable parts and accessories. For most espresso products that includes the portafilter basket, metal portafilter inserts, water tank and so on. Next I run one brewing cycle with just hot water to flush away any residual material from manufacturing.

Dirt and dust can also confuse a robot's array of sensors. Whether your vacuum uses lidar, an optical system or basic navigation hardware, it won't run properly if it can't see or sense its surroundings. 

The water I scooped from a natural water hole seemed to magically turn into bottled spring water inside the Astrea bottle. If the Astrea One bottle didn't have its filter in place, it would just be a normal wide-mouth stainless steel water bottle, making it super easy to clean: The bottle opening is wide enough to fit a standard dish scrubber inside, and the cap has an extra opening where the filter attaches to make sure you hit all the nooks and crannies. 

Espro Press P5
One tried-and-true cold brew method for making cold brew is to use a French press, with the coffee steeping overnight. One drawback to these simple contraptions though is they tend to have poor filters. The result is often a gritty drink -- solid coffee grounds suspended in a liquid solution, especially if you don't have a coarse grind for your beans. The $60 Espro Press P5 tackles the gritty coffee grounds problem by using two stainless steel mesh filter baskets. The extra level of filtration helps the P5 create cold brew (or hot) that's wonderfully smooth and flavorful. However, the beverage the Espro brews isn't as concentrated as what other products make. Another detractor is the Espro's price. It costs twice as much as an ordinary French press. 

The Geopress is made of BPA-free polypropylene, a durable type of plastic. The wide base diameter of the Geopress gives it a sturdy feel, and it's apparently designed to withstand 10-foot drops onto concrete while it's full of water. Without a doubt, the Geopress is the bottle I'd choose to take on a backpacking trip due to its intense filtering mechanism and durability. 

Bialetti Moka stovetop coffee maker
Amazon Turn up the whimsy with this Bialetti stovetop espresso maker, preferably in a bright color. There is something very satisfying about watching coffee bubble up the spout and into the pour section of one of these portable espresso makers (also called a Moka Pot). As pretty as they are functional, these items are great to leave out as conversation pieces. Make coffee while camping by placing this coffee maker over your portable burner.
