Smart Washer vs Smart Plug: Which Fits Your Laundry Room?
A plug gets you finish alerts and power tracking for about $15, but it can't start a cycle or read an error code.
The short answer
If your washer works, a $10 to $25 power-monitoring smart plug gets you cycle-finished alerts and energy tracking, and that's enough for most people. It can't start a cycle, lock the door, or read error codes. Buy a smart washer only when you're replacing the machine anyway, since the smart premium often runs roughly $100 to $300.
- Typical cost
- $10 to $25 for a smart plug; roughly $100 to $300 extra for smart features on a new washer
- Time needed
- Under 30 minutes to set up a plug and alert
- Skill level
- Beginner
Key points
- A smart plug can detect when a cycle ends by watching power draw, but it cannot start a wash or report cycle data.
- Built-in smart washers add remote start, cycle stage tracking, and app-based error codes and diagnostics.
- The cost gap is roughly $10 to $25 for a plug versus an often-cited $100 to $300 smart premium on a new machine, so replacing a working washer just for the app rarely pays.
- Compare the washer's nameplate amp draw to the plug's rating, and never use a plug to cut power mid-cycle.
- Renters and owners with a working washer should buy the plug; replacement buyers should choose on wash performance first and treat smart features as a bonus.

A $15 smart plug can tell you when your washer finishes a cycle, and that's the feature most people actually want. It can't start the wash, open the door, or explain an error code. That gap is the whole decision.
What does a smart plug actually do on a washing machine?
A smart plug with power monitoring watches how many watts your washer pulls and triggers alerts or schedules based on that number. It sits between the wall outlet and the washer's cord, so it knows nothing about the machine itself, only the electricity passing through.
In practice, that gets you three things. You get a phone notification when power drops near zero for a few minutes, which usually means the cycle is done. You see how much energy each load uses. And you can cut power remotely, though not mid-cycle (see the warning below).
Many washers don't start washing just because power returns. You still have to load the machine, pick a cycle, and press start. So scheduling a plug to "turn on the washer at 2 a.m." usually just wakes up a washer that sits waiting for you. Washers also pause during soaks and fills, so set your alert to wait three to five minutes of low draw before it fires, or you'll get false finish pings.
What does a smart washer add beyond the app?
A smart washer talks directly to the machine's own controls, so it can report cycle stage, time remaining, and diagnostics, and it can accept a remote start. Because the washer reports what it's doing instead of you inferring it from wattage, the data is accurate.
Here's what a plug can't copy:
- Remote start. You load the washer, close the door, enable remote start on the machine, then launch the cycle from your phone. Exact steps vary by brand.
- Cycle stage and time remaining. You see wash, rinse, or spin, not just a wattage line.
- App-based error codes. A drain or door-latch fault shows up with a plain-language explanation, which saves a manual hunt.
- Remote diagnostics. Some manufacturers can read machine data for service calls. Availability depends on the brand and model.
Smart washers need Wi-Fi only for the smart features. The machine washes fine offline, but the app, alerts, and remote start stop until the connection returns, and many models join only the 2.4 GHz band. A basement laundry room with weak signal is a common reason these features flake out.
Smart washer vs smart plug: features, cost, and limits
The smart plug wins on price and flexibility, and the smart washer wins on control and information. The table shows where each lands.
| Feature | Smart plug | Smart washer |
|---|---|---|
| Typical cost | $10 to $25 | Roughly $100 to $300 above a comparable non-smart model |
| Works on your existing washer | Yes | No, requires a new machine |
| Cycle-finished alert | Yes, inferred from power draw | Yes, reported by the machine |
| Remote start | No | Yes, after you load it and enable the setting |
| Cycle stage and time left | No | Yes |
| Error codes and diagnostics | No | Yes, in the app |
| Energy tracking | Yes, whole-machine watts | Varies by brand and model |
| Door lock control | No | Varies by model |
| Needs Wi-Fi | Yes | Only for smart features |
| Moves to your next home | Yes | Only if the washer comes with you |
The exact premium is blurry. Manufacturers often bundle Wi-Fi with higher trim levels that also add bigger drums or extra cycles, so you may be paying for more than an app. Compare two models with the same capacity and wash features before you decide what connectivity actually costs.
Where does the smart plug win?
The smart plug wins whenever your washer already works and your real goal is knowing when it's done. It installs in minutes, costs a fraction of any appliance upgrade, and travels with you when you move.
It also works on any washer, including a 12-year-old top-load machine that no manufacturer app will ever support. The same plug can move to a dehumidifier or a utility-room fan later. And an energy monitoring smart plug may give you numbers a basic smart washer app doesn't.
Renters get an easy call. You can't buy the landlord's washer, and a plug leaves no trace when you unplug it.
Where does the smart washer win?
The smart washer wins on anything that needs the machine to talk back: remote start, error codes, and accurate cycle status. A plug can only guess from watts. A washer can simply tell you.
Remote start matters most if you want to load the washer, then start it from another floor or time a finish for when you're home to move the load to the dryer. Error codes matter when the washer stops at the worst moment. Reading a drain-pump fault in an app beats paging through a printed manual, and it might save a service call.
Smart features alone rarely justify replacing a working machine. A newer front-load washer or top-load washer that's ENERGY STAR certified can use less water and energy than a much older model, and that's the better reason to upgrade. The ENERGY STAR product listings show current certified washers.
What should you check for safety and compatibility before you buy?
Match the plug's amp rating to the washer's nameplate draw, buy a safety-listed plug, and plug it straight into a grounded wall outlet. Skip any of those and a $15 purchase can turn into a damaged outlet.
- Amp rating. Look for a plug rated 15 amps. Many washers pull well under that, but models with heating elements can draw more. If the nameplate figure sits close to the plug's rating, skip the plug.
- Listing. Buy plugs with a recognized safety listing such as UL or ETL. Skip unbranded ones with no markings.
- Direct connection. Use the wall outlet, not an extension cord or power strip.
- Location. Keep the plug off the floor and away from supply hoses. A water leak sensor under the machine is a smarter add-on than any plug automation.
If the outlet feels warm, grips the plug loosely, or has no ground, stop and have a licensed electrician look at it. Ordinary smart plugs also can't handle 240-volt circuits, so don't try one on an electric dryer.
Smart plugs and appliances are internet-connected devices, so use a unique Wi-Fi password and keep their apps updated. CISA publishes general guidance on securing home networks and connected devices, and the FTC offers consumer advice on connected products and privacy. If you're buying a plug now, one that supports Matter from the Connectivity Standards Alliance can work with more smart-home systems, though built-in washers have limited Matter support at this point.
Which should you pick: renters, owners, or replacement buyers?
Buy the smart plug if your washer still works, and buy a smart washer only when you're replacing the machine anyway. That's our pick for the most common situation, because $15 captures most of the daily benefit.
- Renters: Plug. You get finish alerts and energy tracking without touching the landlord's appliance. Check your lease if you're unsure about adding devices.
- Owners with a working washer: Plug. Home washers are often cited as lasting roughly 10 to 14 years, depending on use, so there's no reason to retire a good one for an app.
- Owners with an aging washer: Start shopping once it's around 10 years old or a repair quote nears half the price of a new machine, a common rule of thumb. Choose on drum capacity, wash performance, and ENERGY STAR certification first. If a smart model costs only about $100 more than an equivalent non-smart one and you'll use remote start or diagnostics, take it.
- New-home or first-time buyers: A smart washer is reasonable if the price gap is small. You can add a plug later, so don't stretch the budget for it.
Next step: check your washer's nameplate for its amp draw, then order a 15-amp plug with energy monitoring and set one alert for when power stays near zero for four minutes.
Questions people ask
Will a smart plug void my washer's warranty?
It might create a dispute, because some manuals say to plug the washer directly into a dedicated grounded outlet. Read your owner's manual and warranty terms before adding one. If the washer is still covered, call the manufacturer to confirm.
Can I use a smart plug on my dryer too?
Not on an electric dryer, which runs on a 240-volt circuit that ordinary smart plugs can't handle. A gas dryer uses a standard 120-volt outlet, so a plug rated for its load may work for finish alerts, but check the manual first.
Does a smart washer save more energy than a regular one?
Not because of the Wi-Fi. Efficiency comes from the washer's design, which is why ENERGY STAR certification is a better thing to check than the smart label.
Is it safe to leave a smart plug on a washer all the time?
Generally yes, if the plug is rated for the washer's load, carries a safety listing, and sits in a grounded wall outlet. Watch for warmth, discoloration, or a loose fit, and replace the plug at the first sign. If the outlet itself runs warm, stop using it and call an electrician.
Will a smart plug work with Alexa or Google Home?
Most popular plugs do, but compatibility is listed on the box or product page, so check before you buy. A plug that supports Matter is more likely to work across several systems.
