Buying a refurbished robot vacuum: 7 pros and cons

Robot vacuums are more popular than ever. But even as they become more common, they still come with a hefty price tag—especially for models with the latest features.

If you’re looking to add a robot vacuum to your home without stretching your budget, a refurbished model might be the perfect solution. It can offer a significant savings, while also reducing electronic waste.

Before you make a purchase, though, it helps to know what you’re getting into. From potential savings to questions about reliability, this guide covers everything you need to know to make an informed choice.

What “refurbished” really means

First, let’s clear up what “refurbished” actually means. A refurbished robot vacuum isn’t simply a used device that’s been put back on the shelf; it’s typically one that’s been returned to the manufacturer or retailer due to a minor defect, cosmetic issue, or buyer’s remorse.

After being sent back, it goes through a rigorous testing process. Technicians inspect and repair any issues, replacing parts where necessary to bring it up to like-new condition. In some cases, it may even involve software updates to enhance functionality.

It’s worth distinguishing refurbished items from “open-box” or “used” ones. Open-box items are generally returns that haven’t undergone repairs because they weren’t found defective; they’re essentially unused but not “new.”

Used items, on the other hand, are pre-owned devices sold as-is, often with no inspection or testing. Refurbished items fall somewhere between the two, offering both affordability and reliability.

Pros of buying a refurbished robot vacuum

Purchasing a refurbish vacuum offers a variety of benefits, including…

The price

Refurbished models typically cost a fraction of a brand-new one, allowing you to get higher-end features without the higher-end price tag.

For those who want advanced navigation, powerful suction, or smart home integration, refurbished models can be a golden opportunity to upgrade without overextending the budget.

Making an eco-friendly choice

Electronic waste is a growing problem, with countless devices ending up in landfills. By choosing refurbished, you’re helping cut down on waste and promoting a more eco-friendly approach to consumer electronics.

Quality control

Most refurbished devices undergo extensive testing, sometimes even more thorough than new models. Manufacturers and certified sellers typically examine every component to identify and fix any issues.

This level of care means you’re often getting a reliable product with some assurance that it won’t fail on you right out of the box.

Warranties

While the warranty may not match that of a new model, it’s typically enough to cover any initial hiccups, giving you a buffer of protection and peace of mind.

This extra coverage can make a huge difference if you’re wary about buying pre-owned electronics.

Cons of buying a refurbished robot vacuum

Of course, buying refurbished isn’t always a perfect solution. Some of the downsides include…

Shorter lifespan

While refurbished models are tested and repaired, they may already have some wear on components, especially the battery. Robot vacuums are designed for daily or near-daily use, so older models could show signs of age faster than a brand-new vacuum.

If longevity is a priority, be prepared to eventually invest in some replacement parts like a new battery or brushes.

Limited selection

Since refurbished models come from returns or excess stock, you won’t always find the latest model or all the features you’d get with a new one. If you’re set on a specific model or advanced capabilities like self-emptying dustbins or high-end mapping, the refurbished market might not always have what you’re looking for.

Older models may also lack support for the latest app features and firmware updates, which can affect performance or limit compatibility with other smart home devices.

Limited tech support

Some refurbished models may come with limited or no tech support from the manufacturer, especially if they’re a few generations old. So, while you’re getting a discount, you might also miss out on certain perks—like troubleshooting help or software updates—that come standard with a new purchase.

If you’re sold on the idea of a refurbished robot vacuum, it’s important to know which features to prioritize.

The first thing to check is battery health, as the battery’s condition will have a big impact on how well the vacuum performs and how long it lasts. Many refurbished sellers don’t provide specific battery details, but some reputable sources will replace the battery or provide testing results to give you an idea of what to expect.

Cleaning performance is another top consideration. Look for models with strong suction and good brush quality, as these are essential for tackling dirt, pet hair, and other debris. If possible, seek out models with advanced navigation systems, like LIDAR or camera-based mapping, which help the vacuum navigate more efficiently and avoid obstacles. These features can make a big difference in how efficiently the vacuum cleans.

Don’t forget smart features, especially if you have a smart home setup. Models with Wi-Fi connectivity, app control, and voice assistant compatibility can enhance the overall experience and make it easier to control and schedule cleanings remotely. Just be mindful that older models may not support the latest smart home standards or features.

Where to buy a reliable refurbished robot vacuum

Buying from a trusted source is essential with refurbished products. Look for refurbished models from official manufacturers, such as iRobot, Roborock, or Ecovacs, as they usually include a manufacturer’s warranty and have gone through official testing.

Certified resellers like Amazon Renewed or Best Buy’s Geek Squad-certified program also offer warranties and return policies, giving you more security if the product doesn’t meet expectations.

Exercise caution

Be cautious about buying from unknown third-party sellers, especially if they don’t offer a warranty or return policy.

Some unscrupulous sellers have been known to exploit iRobot’s Select program by selling deactivated Roombas to unsuspecting buyers. These vacuums are remotely disabled by iRobot if the original owner stops paying the subscription fee, leaving the new buyer stuck with a non-functional device.

Always check reviews, certifications, and policies—if a deal seems too good to be true, it probably is.

Ask questions before buying

To make sure you’re getting a solid deal, don’t hesitate to ask the seller some important questions.

Ask about any testing and parts replacements done during refurbishment. Inquire about the warranty coverage and whether there are any existing issues with the product.

Finally, verify the return policy, so you know your options if the vacuum doesn’t work out.

Tips for extending the life of a refurbished robot vacuum

Once you’ve made your purchase, a little maintenance can go a long way. Regularly emptying the dustbin, cleaning the brushes, and wiping down sensors will keep the vacuum working efficiently. Periodically check the battery’s charge and replace it if you notice it running down more quickly than usual.

Replacing filters and other consumable parts on schedule can also help maintain performance, ensuring you get the most out of your refurbished vacuum.

Balancing savings with quality: a smart choice

Buying a refurbished robot vacuum can be a smart way to enjoy the perks of automated cleaning without paying full price. While there are some potential downsides, like shorter lifespan and limited tech support, the cost savings and eco-friendly impact can make it worthwhile.

By prioritizing the right features, buying from reputable sources, and taking good care of your purchase, you can enjoy a clean home on a budget.

Refurbished or not, a robot vacuum can be a reliable household helper—especially if you know what to look for.
