We had a $900 robot vacuum cleaner, but our elderly cat mistook it for a litterbox and peed on it, rendering it inoperable. After she died, I bought this cheap Lefant Robot Vacuum Cleaner, and it works as well as the costly one did. It comes with a smartphone app, but I don’t use it. I just push the button and it shoots out of the charging port and starts rolling around sucking up dirt. When the batteries are low it finds its way back to the charger. — MF

A tiny smart plug allows me to control any plugged in device from a voice command given to Alexa. I say, “Alexa, christmas tree lights on” and bingo, they’re on. I use Gosund Smart Plugs, the size of a small adaptor that plugs into the wall. They come in a pack of 4 for $29, which is about the same price as one official Amazon brand smart plug. All are pretty easy to pair to your home’s wifi and Alexa or Google. Or you can also control devices from your phone from far away. You can control anything that you can leave in the “on” state. This is the simplest, cheapest version of a smart home. — KK

We changed sides a few years ago. We went from being a live-Christmas-tree family to embracing a fake tree. Artificial trees have gotten so good looking, so inexpensive, and so easy to assemble, that we are now happy owners of a forever tree. And new ones get better each year. The most realistic trees come from National Christmas Tree Company; they are usually at the top of Wirecutter’s recommendations. The best ones have LED lights built in. We went with a budget, light-less 7.5ft tall Douglas Fir from National for $180. Once decked out with our own lights, and covered with ornaments, you can’t really distinguish it from a real tree. — KK

Until recently, I used crumpled sheets of newspaper to start fires under my charcoal chimney, but I stopped subscribing to print editions of newspapers. I started buying Weber Lighter Cubes instead. They’re the size of an ice cube and ignite charcoal briquettes even faster than newspaper. — MF

In a recent issue of my Magnet newsletter, I asked readers to help me separate two coffee cups that somehow got stuck together. (It’s the second-to-last item in the newsletter.) Almost all of the hundreds of suggestions I received involved cooling the small cup and heating the big one to allow thermal expansion to do its work, but that didn’t help. Can Recomendo readers come up with a solution? Send email to: markfrauenfelder+stuckcups@gmail.com — MF

A cleaning hack I just learned: cut the corner of the sponge I use solely for the cast iron vs all the other dishes. Found in The 30 Most Brilliant Cleaning Hacks of All Time. I guarantee you will find some tips you’ve never heard of before on this list, like microwaving your cleaning rag or using a mesh laundry bag in the dishwasher. — CD

I bought this King size set of bamboo bedsheets for $40 because they have side pockets to stow a book, Kindle, or phone. I wasn’t expecting them to feel so nice! They are much more comfortable than the $200 bamboo sheets we bought at Bed Bath and Beyond (which didn’t come with pockets). — MF

After our recent kitchen remodel, every appliance in our kitchen is now stainless steel and of course, easily smudged. My husband then added the Weiman Stainless Steel Cleaner to our cleaning supplies and honestly, I was surprised at how flawless it left every surface. Every home should have this. — CD

I bought this DYMO Portable Label Maker ($23) because it was an Amazon best seller and I didn’t want to put that much research into it, but now it’s been almost a year that I’ve owned it and it’s still incredibly useful and has not let me down. It’s so intuitive that months have gone by between use and I don’t have to remind myself how to work it. I love that it’s so light. I can walk around with it, type on it, print and cut my label and put it back in one fell swoop. — CD

The best way to untangle a knotty tangle is to not to “untie” the knots, but to keep pulling the loops apart wider and wider. Just make the mess as big, loose and open as possible. As you open up the knots they will unravel themselves. Works on cords, strings, hoses, yarns, or electronic cables. — KK

We live in a house with walls that have chicken wire behind the plaster. They do a great job of blocking Wifi. To get around it, I installed a Frankensteinian hodgepodge of cables, powerline adapters, and wireless access points all around the house. They all had different SSIDs and the coverage was still spotty. It was frustrating. A decade later, I broke down and bought a Google Nest router and four wireless hubs. It set me back $500 but now we have great coverage throughout the house with no need to change SSIDs on our devices as we move from one room to the next. I expected my family to be grateful, Instead they are mad at me, “Why didn’t you get this sooner!?” — MF

I reuse jars from the kitchen, for storage and for display items. Getting the jar labels off was a chore until I started using Goo Gone (which we’ve mentioned before but never explicitly recommended). It’s an odorless penetrating oil that unsticks adhesives from anywhere people stick stuff. Spray on, let soak and peel off. Leaves a temporary oil film that evaporates. — KK

We have a chocolate lab and a long-haired cat and their dark hairs can be found on every surface of our house. This $25 reusable roller (ChomChom Roller) is the fastest and easiest way to clean our couch and comforter. You just roll back and forth over flat surfaces and the roller catches all the hair in a dust receptacle that you empty out. Much more efficient than sticky lint rollers. — CD

We live in an old house and the sewer pipes get clogged a lot. I got tired of paying a plumber $150 to clear the pipe every time it clogged, so I bought this $22 hose attachment, called a Drain King. It’s a rubber bladder that you insert into the sewer line opening. When you turn the hose on, the bladder expands, forcing the water to push the clog out. It has never failed me. Read the glowing testimonials on Amazon for this thing. — MF

We have yet to upgrade our old washer and dryer, but my husband upped our laundry game by buying these Wool Dryer Balls ($7, 6pk). They accelerate drying time by absorbing moisture and help prevent static cling. — CD

If you are looking for something in your house, and you finally find it, when you’re done with it, don’t put it back where you found it. Put it back where you first looked for it. — KK

My daughter needed a lamp to light up her drawing board, so I bought this $15 CeSunlight LED clip-on lamp with a flexible neck. She can adjust the brightness and color temperature and to provide the ideal illumination for her work. — MF

This LPT was a housekeeping game changer: Use a seam ripper to easily clean out hair tangled in a vacuum brush. My hair is long and everywhere and before I use to struggle with scissors to cut it out of the vacuum, but it turns out a seam ripper is the perfect tool for the job. — CD

I wanted a way to open my garage door remotely, so I bought the Meross Smart Wi-Fi Garage Door Opener Remote ($30). It took just a few minutes to install and configure. Now I can open and close the door with my phone, and get an alert when someone else opens it. It also works with voice assistants. — MF

I saw one of these cute cloud-shaped magnetic key holders ($7) at my friend’s place and wanted one immediately. It solves my one reoccurring problem: not knowing where I put my keys. It came with adhesive backing so I was able to “set it up” right away. Easy peasy. — CD
