Have you ever marveled at how some people seem to pick up new skills or knowledge at lightning speed while others struggle for weeks or months? It’s easy to assume they’re just naturally gifted, but the truth is often far more practical, and replicable. What if you could learn to master any subject or skill […]

Early humans scratched lines on stone walls with rocks, and that primal act sits at the root of every sketch we make today. Most modern pencils are optimized for control and detail, shaped like sticks to give you precision over every line and curve. Alberto Essesi’s unnamed pencil concept takes a deliberate step back toward that raw, gestural way of drawing, translating it into a highly refined spherical object that looks more like a polished pebble than any conventional pencil.
Essesi designed this tool for himself after watching a documentary about prehistoric mark-making and then trying to draw with an actual rock. He noticed how the stone forced him into long, bold lines and larger forms rather than tight details, and decided to capture that feeling in a modern drawing instrument. The result is a palm-sized aluminum sphere with a small conical graphite tip emerging from its edge, held like a stone in your hand.
Designer: Alberto Essesi
The form is deceptively simple. A sphere with a polished aluminum band around the middle and sand-blasted, anodized surfaces on the sides. In use, your hand cups the sphere like you’re gripping a smooth rock, which encourages whole-arm movement instead of fingertip control. That naturally pushes your sketches toward sweeping strokes and energetic shading, exactly the kind of drawing Essesi wanted to encourage by changing the shape of the tool.
The material choices are deliberate. The body is hollowed out to reduce weight, avoiding the fatigue a solid metal ball would cause during long sessions. The polished equator catches light and emphasizes the perfect geometry, while the matte sides diffuse reflections and feel softer against your fingers. That contrast between mirror and satin surfaces gives the object a quiet drama even before it touches paper.
The tip uses an infinite graphite insert, a long-lasting graphite alloy that wears down extremely slowly and doesn’t need traditional sharpening. The conical tip is easily replaceable and is designed to replicate the sensation of a smooth stone grinding against a surface. On paper, it lays down a mark closer to charcoal or a soft pencil, ideal for big shapes and confident lines rather than tight technical work.
The exploded render shows the hollow shell, threaded ring, and domed cap polished as carefully as the exterior. Essesi says he loves making every part, even the invisible ones, as refined as what you see. That approach turns disassembly into its own kind of pleasure, revealing a tiny piece of mechanical jewelry rather than a rough interior with leftover machining marks or unfinished edges.
The pencil nudges you away from fussing over details and toward exploring volume, rhythm, and energy. By abandoning the stick form and embracing a stone-like grip, it changes your drawing style simply by changing the shape of the thing in your hand. It’s less a tool for everyday note-taking and more an invitation to sketch differently.

Amazon is hosting a Black Friday sale that covers many of its ereaders. This includes the Kindle Colorsoft, which has been discounted to $170. This thing usually costs $250, so this is one heck of a deal and a record low price.
The model came out earlier this year and we gave it a glowing review, calling it "the missing link in Amazon's ereader lineup." It's the first Kindle ereader in color, which makes this thing one of the best ways to read comic books and graphic novels. The pinch-to-zoom feature lets you get closer to details, to make each panel really pop.
This is also a high-end ereader, color or not. We found the load times to be exceptionally fast and the same goes for turning pages. There's an auto-adjusting front light, which comes in handy. There are also no lock screen ads by default and a single charge lasts eight full weeks of regular use.
The major downside here is the price. It's tough to truly recommend any ereader at $250, or the original launch price of $280. It's a lot easier to recommend at $170.
Amazon is also selling similar products at a discount, some of which made our list of the best ereaders. The base Kindle is down to $80, which is another record low. The Paperwhite is on sale for $125, yet another record low price. And keeping with the theme, the current-gen Kindle Scribe is on sale for as low as $280, the cheapest we've seen it.

For anyone looking to get a great deal on a streaming device, Roku's Black Friday deals are here. The Roku Streaming Stick Plus, which just happens to be one of our favorite streaming devices, is 50 percent off, on sale for just $19. The regular Streaming Stick and Streaming Stick 4K are also on sale for 47 percent and 50 percent off, coming in at $15 and $25 respectively.
Roku makes some of the best streaming devices you can get, and any of the ones on sale would be great picks to upgrade an old TV you already have. The Streaming Stick Plus is our favorite of the bunch since it supports 4K HDR content and gives you access to a bunch of free content thanks to Roku's streaming OS. We also appreciate its accurate universal search and the fact that it draws power from your TV, so it doesn't need to be plugged into a wall outlet to get power.
The standard Streaming Stick is a good alternative to Amazon's most basic Fire TV Stick, and if you already prefer Roku's streaming OS, it's arguably the better choice. The Streaming Stick 4K adds Dolby Vision into the mix, if that's a must-have for you. Also, if you're looking for a more powerful set-top streaming box, the Roku Ultra is 30 percent off, marked down to $69 from $100.

Looking to keep your home clean without having to vacuum and mop every day, pick up dirt, the dinner your child threw on the floor or your furry friend’s endless pet hair? Join the club. Smart home gadgets have come a long way over the years, and that includes robot vacuums. With newer technology including voice controls, object detection and more automation features, investing in a robot vacuum cleaner makes more sense now than ever before. Some of the best robot vacuum cleaners even have mopping capabilities, roller brush options and self-emptying bases, too, and there are plenty that don't cost a fortune either. If you’re ready to adopt a less hands-on approach and let a robot vacuum cleaner do the hard work for you, consider our recommendations below.
We recommend thinking first about the floors in your home: Do you have carpet throughout, or tile and hardwood floors, or a mix? Robots with stronger suction power will do a better job picking up dirt on carpets as they can get into the nooks and crannies more easily. Some machines have “max” modes as well, which ups suction power but also typically eats battery life faster than the “normal” floor cleaning mode.
Suction power is an important factor to consider. Unfortunately, there isn’t a standard power scale that all robo-vacs adhere to, so it’s difficult to compare among a bunch of devices. Some companies provide Pascal (Pa) levels and generally the higher the Pa, the stronger the vacuum cleaner will be. But other companies don’t rely on Pa and simply say their robots have X-times more suction than other robots. If you’re looking for the best vacuum for your needs, it’s helpful to pay attention to real-world testing and how well the vac can pick up fine dust, crumbs and pet hair in an environment similar to that of your home.
As we explained in our budget guide, Wi-Fi connectivity is a key feature for most robot vacuums. Some of the affordable devices aren’t Wi-Fi connected, though, so it’s best to double check before you buy cheap. Wi-Fi lets a robot vacuum cleaner do things like communicate with a mobile app, which then allows you to control the device from your phone.
Past a certain price threshold, you’ll find advanced perks like home mapping features, improved object detection and automatic dustbin disposal. Home mapping is exactly what it sounds like: The vacuum uses sensors to map your home’s layout as it cleans, allowing you to send it to particular rooms or avoid no-go zones where you don’t want it to roam.
Most robo-vacs have object detection, but some will be better than others at actually avoiding things like chair legs and children’s toys. High-end models even go so far as to promise obstacle avoidance to steer clear of things like pet poop that can potentially ruin your machine.
Finally, for peak convenience, consider a self-empty robot vacuum that comes with a self-empty station. These are basically garbage bins attached to the machine’s docking station. At the end of each job, the robo-vac automatically empties its small dustbin into the large clean base – that means you won’t have to empty the dustbin yourself and you’ll only have to tend to the base once every few weeks.
Just keep in mind that most self-emptying bins require proprietary garbage bags – another long-term expense you’ll have to factor in. Also, any vac-and-mop robot with a water tank will not dump its dirty water into the clean base, so you’ll still have to clean up that yourself.
Mopping capabilities are much more common now in robot vacuums than they were just five years ago. Machines with this feature have a water tank either built into the robot’s chassis, the auto-empty bin or as a separate piece that you swap in for the dustbin when you want to mop your floors. It makes the robo-vac more useful if you have hard floors in your home that you like to keep squeaky clean, but it does require more work on your part.
Filling and emptying the reservoir remains a human’s job for the most part (except on the most expensive machines), as does adding cleaning solutions if the mopping robot comes with this feature to ensure it uses clean water for every cycle.
First and foremost, always empty your robot vacuum’s dustbin after every cleaning job. If you have a model with a self-emptying base, there’s less work for you to do yourself. If not, simply detach and empty the dustbin as soon as the robot is done cleaning. It’s also a good idea to take a dry cloth to the inside of the dustbin every once in a while to remove any small dust and dirt particles clinging to its insides.
In addition, you’ll want to regularly examine the machine’s brush roll to see if any hair has wrapped around them, or if any large debris is preventing them from working properly. Some brushes are better than others at not succumbing to tangled hair, but it’s a good idea to check your robot’s brushes regardless — both their main brush and any smaller roller brushes or corner brushes they have. These parts are often easy to pop off of the machine (because they do require replacements eventually) so we recommend removing each brush entirely, getting rid of any tangled hair or other debris attached to them and reinstalling them afterwards.
Robot vacuums also have filters that need replacing every couple of months. Check your machine’s user manual or the manufacturer’s website to see how long they recommend going in between filter replacements. Most of the time, these filters cannot be washed, so you will need to buy new ones either directly from the manufacturer or from other retailers like Amazon or Walmart.
We primarily test robot vacuums by using them as they are intended to be used: in a home, across different types of flooring and in the face of all sorts of messes including pet hair, spilt coffee grounds and other food debris, dust bunnies and more. We set up all robot vacuums according to their provided instructions and run multiple cleaning jobs during a testing period of at least one to two weeks per machine.
If the robot has mopping capabilities, we also test those as well on hardwood and tile flooring. For models with self-emptying bases, we rely on those built-in trash cans for all post-job cleaning, and we make sure to test the robot vacuum's mobile app for usability and convenience. As we're testing, we make note of things like how loud the robot and its components are, how much human attention the robot needs on a regular basis, how the robot handles large messes and big dust bunnies, if the robot gets stuck on rugs, doormats or other furniture and more.
We tackled this question when we reviewed budget robot vacuums and the answer is yes, especially if vacuuming is one of your least favorite chores. Robots take the hard work out of cleaning your floors – just turn the thing on and watch it go. Any robot vacuum cleaner worth buying is semi-autonomous in that it will suck up dirt around your home until its battery is low and then make its way back to its charging dock. Unlike a regular vacuum, you should only have to interact with it to turn it on, empty its dustbin and untangle it if it were to get stuck somewhere.
That’s not to say robot vacuums are perfect. They’re almost always less powerful and less flexible than traditional vacuums. Since most robo-vacs are much smaller than traditional models, they often don’t have the same level of suction you’ll get in an upright machine. Plus, their dustbins are smaller, so they will need to be emptied more frequently. While Wi-Fi-connected robot vacuums give you the flexibility to start a cleaning job from anywhere using an app, targeting a small area of your home can be more complicated. Some robo-vacs have spot-cleaning features that focus the machine’s attention on a specific area, which almost – but not quite – mimics the spot-cleaning you’d be able to do yourself with a regular or cordless vacuum.
Robot vacuums can last many years, if you take care of them properly. Check out our recommendations for robot vacuum maintenance above, but in a nutshell, you should make sure that you're emptying the machine's bin after every job and periodically cleaning the interior of the bin and the brushes. It's also a good idea to check the user manual to see how often your robot vacuum's filter needs changing.
There's no straight answer to this question. Robot vacuums offer more convenience than handheld vacuums, so for those who are looking to automate a chore, that could mean one of these devices works better for them than a standard vacuum. However, handheld vacuum cleaners often have stronger suction power, and they give the user a bit more control. It ultimately depends on how you intend to use your main vacuum cleaner and what you want to prioritize most.
Cleaning a robot vacuum isn’t too much of a chore, but you’ll want to give it a little TLC every few weeks or so, depending on how often you’re running it and how much dirt it’s picking up. The dustbin usually needs to be emptied after each cleaning run, especially if you have pets or lots of carpet where dirt can hide. Many newer models have self-emptying docks, which means you won’t have to empty the dustbin yourself after every use, but the main bin will still need a good clean once a month or so. Also, it’s a good idea to check the side brushes and main brush for any hair tangles or debris every couple of weeks to keep things running smoothly.
Robot vacuums won’t work for everyone. One of the biggest drawbacks is that they usually don’t have the same suction power as a full-sized upright vacuum or even a cordless stick vacuum, so they might struggle with deep-cleaning thick carpets. They’re also designed for floors only, so if you’re looking to clean furniture, stairs or other tricky spots, you’ll still need a traditional vacuum to do that. Plus, they can sometimes get stuck or miss spots, especially if you’ve got a lot of furniture or obstacles in the way. While their sensors help, they might still bump into things or need a little help getting out of tight spots. And while most have decent dirt detection features, they’re best for keeping things tidy rather than doing heavy-duty cleaning.
