Top Robot Vacuum Brands for Customer Service

When shopping for a robot vacuum, most people compare suction power, navigation, and features. But what about customer service? After all, even the best robot vacuum can break down or need troubleshooting. At Vacuum Wars, we analyzed some of the biggest robot vacuum brands—using Amazon reviews, third-party ratings, warranty and return policies, and live support tests—to see how they stack up against each other. The results reveal which companies are easiest to contact, how their return and warranty policies compare, and general customer sentiment.

How We Measured Customer Service

Evaluating customer service in consumer tech is challenging because experiences vary widely. To keep our scoring both transparent and reliable, we built the Vacuum Wars Customer Service Score around four categories: Amazon reviews, third-party ratings, return and warranty policies, and access to a live customer service agent.

Amazon Reviews: First-Hand Experiences

We collected over 100 recent reviews per brand, limited to robot vacuum products (not accessories) and published in the last 12 months. Each review was manually filtered to ensure it described the brand’s customer service, not Amazon’s. Reviews were indexed as positive, neutral, or negative.

Common frustrations included warranty disputes, long email exchanges, repeated troubleshooting steps, and products failing just outside the warranty window. On the positive side, some brands—most notably Eufy—reached out to dissatisfied customers, turning negative reviews into positive ones. Because these reviews reflect direct user experiences, we gave them the heaviest weight in the final score.

Third-Party Scores: Trustpilot and BBB

To balance anecdotal reviews, we included Trustpilot ratings (percentage of five-star reviews) and Better Business Bureau grades (complaint resolution). Both were converted to a 0–10 scale, averaged, and given a lighter weight than other categories. This data revealed interesting contrasts—for example, some brands held A+ BBB ratings but had overwhelmingly negative Amazon feedback, highlighting a gap between formal complaint resolution and everyday customer experiences.

Return and Warranty Policies

We compared each brand’s written policies. Most offer 30-day returns and one-year limited warranties. Brands scored higher if they extended return windows, covered shipping for defective returns, or avoided hidden deductions like restocking fees. We deducted points when policies placed the burden on the customer, such as requiring return shipping even for defective units.

Access to a Human Agent

Finally, we tested each brand’s North American customer service line by calling on a weekday just before 5 PM Eastern. We measured time to reach a human, availability of callback systems, and the complexity of phone menus. While all agents we spoke with were polite and professional, access varied. Because responsiveness is critical when problems arise, this factor carried a heavy weight in the final score.

Why These Brands Were Included

We focused on six major brands with enough data for meaningful comparison. To qualify, a brand needed at least 100 customer service–related Amazon reviews from the past 12 months. Younger or smaller brands didn’t meet this threshold but would be added in future updates as more feedback becomes available.

#1 – Roborock

Amazon Score: 46% positive/neutral, 54% negative
Policies: Standard—30-day returns, shipping covered if defective, 1-year warranty
Third-Party: <20% five-star Trustpilot ratings, F rating on BBB
Phone Test: Under 1 minute to reach a live agent

Roborock’s customer service reputation on Amazon is mixed, but they still performed above average with about 46% of customers describing their experience as positive or neutral. Happy users praised Roborock for responsive and generous support while some reported frustration, particularly around warranty disputes and being asked to jump through hoops before receiving help.

Their third-party ratings were poor, with less than 20% positive reviews on Trustpilot and an F grade from the Better Business Bureau due to low engagement with complaints.

On the policy front, Roborock largely follows industry standards: a 30-day return window, free return shipping for defective units, and a one-year limited warranty. Nothing here stands out as exceptional, but nothing fell below expectations either.

Where Roborock excelled was in human agent access. Like Dreame, they connected us with a polite, professional representative in under a minute. This reliability in reaching live support earned them a perfect score in this category and helped offset their weaknesses elsewhere.

Bottom line: Roborock’s combination of fast human support and average-to-above-average Amazon sentiment—despite poor Trustpilot and BBB results—was enough to place them at #1 in our customer service rankings.

#2 – Dreame

Amazon Score: 42% positive/neutral, 58% negative
Policies: Standard—30-day returns, shipping covered if defective, 1-year warranty, refunds processed in 5–10 business days
Third-Party: <20% five-star Trustpilot ratings, no usable BBB data
Phone Test: Under 1 minute to reach a live agent

Dreame’s customer service results placed them firmly in the middle of the pack, but their strong performance in live support pushed them to #2 overall. On Amazon, 42% of reviews were positive or neutral while 58% were negative, leaving them slightly below average compared to other brands in this study. The most common frustrations included unhelpful troubleshooting scripts, warranty difficulties, and poor communication. Satisfied customers reported quick and friendly resolutions, and a handful updated their reviews to positive after Dreame reached out to address their concerns.

On third-party platforms, Dreame’s scores were weak. Trustpilot showed fewer than 20% five-star ratings, and there was no usable data available from the Better Business Bureau, limiting how much weight we could place on this category.

Dreame’s written policies were mostly standard. They offer a 30-day return window, cover shipping for defective units, and include a one-year limited warranty. Customers are told that refunds take 5–10 business days, which is fairly typical. While the policies don’t go above and beyond, they didn’t reveal any unusual drawbacks either.

Where Dreame truly excelled was in human agent access. When we tested their support line, a polite and professional representative answered in under a minute, earning them a perfect score in this category. This reliability set them apart from several competitors, who required long wait times or complex phone menus.

Bottom line: Dreame’s fast, reliable access to live support was strong enough to counterbalance their weaker Amazon and third-party results, keeping them near the top of the list at #2 in our customer service rankings.

#3 – Ecovacs

Amazon Score: 68% positive/neutral, 32% negative
Policies: Weak—30-day returns, customer pays shipping, refunds reduced by shipping cost, 1-year limited warranty
Third-Party: <10% five-star Trustpilot ratings, D rating on BBB
Phone Test: 2.5 minutes to reach a live agent

Ecovacs stood out for having the strongest Amazon results of any brand in our study. Nearly 70% of customer service reviews were positive or neutral, with some buyers even describing Ecovacs as the best service they’d ever received—noting quick responses, generous solutions, and a willingness to go above and beyond. That said, the remaining 32% of reviewers reported long waits, unhelpful troubleshooting, warranty headaches, or expensive repair costs, showing that experiences remain mixed.

Where Ecovacs faltered was in third-party ratings. Trustpilot reviews were mostly negative, with fewer than 10% awarding five stars, and the Better Business Bureau assigned them a D rating for complaint handling. This contrast highlights the difference between organic user experiences on Amazon and the brand’s track record with formal complaint platforms.

Ecovacs also posted the weakest written policies of the six brands we tested. Customers have just a 30-day return window, must always pay for return shipping, and refunds are reduced by the original shipping cost. Warranty coverage is standard at one year, but the restrictive return terms pulled their policy score lower than any competitor.

In terms of live customer support, Ecovacs performed reasonably well. We reached a human agent in about 2.5 minutes, though the process was complicated by a pre-recorded phone system that repeatedly pushed callers toward an online chat option. While not the slowest brand in our test, it was less seamless than Roborock or Dreame.

Bottom line: Ecovacs earned high marks from everyday customers on Amazon but lost ground with poor third-party ratings and restrictive return policies. That combination left them in the middle of the pack at #3 in our customer service rankings.

#4 – Shark

Amazon Score: 38% positive/neutral, 62% negative
Policies: Above average—60-day return window, customer pays shipping, occasional restocking fee, 1-year limited warranty
Third-Party: <10% five-star Trustpilot ratings, A+ rating on BBB
Phone Test: Under 1 minute to reach a live agent

Shark’s customer service results reveal a brand with strong policies on paper but mixed execution in practice. On Amazon, just 38% of reviewers reported positive or neutral experiences, while 62% left negative feedback. The most common complaints involved lapsed warranties, repeated troubleshooting steps, and difficulty reaching effective support. A smaller group of customers did report smooth, straightforward resolutions, but frustration with warranty fulfillment was the dominant trend.

On third-party sites, Shark showed a very different profile. Trustpilot reviews were poor, with fewer than 10% of customers leaving five stars. However, the Better Business Bureau awarded Shark an A+ rating, reflecting high engagement with complaints once they were formally submitted. This highlights a split between everyday customer frustration and the company’s more official complaint-handling processes.

Shark’s return and warranty policies looked stronger than average compared to competitors. Their 60-day return window is twice as long as the standard, though customers are responsible for return shipping and may face a small restocking fee in some cases. Warranty coverage is standard at one year with some options for expanding warranty windows. On paper, these terms positioned Shark favorably in our scoring system.

In our human access test, Shark excelled. A polite, cheerful representative answered the phone in under a minute, making Shark one of the fastest brands to reach. This quick response earned them a perfect score in this category.

Bottom line: Shark combined generous return terms, strong BBB engagement, and fast access to live support, which boosted their score significantly. However, Amazon reviewers consistently reported frustration with warranty fulfillment and troubleshooting, showing that the real-world customer experience often falls short of the policies themselves. Had their Amazon sentiment aligned more closely with their strong on-paper performance, Shark would likely have ranked much higher.

#5 – iRobot

Amazon Score: 22% positive/neutral, 78% negative (lowest of any brand)
Policies: Excellent—60-day return window, prepaid return shipping, no restocking fees, 1-year limited warranty
Third-Party: <10% five-star Trustpilot ratings, A+ rating on BBB
Phone Test: 7 minutes to reach a live agent (with callback option)

iRobot ranked last in Amazon customer sentiment, with only 22% of reviews positive or neutral and nearly four out of five reviewers describing negative experiences. This translated to the lowest score of any brand in our study. Customers frequently cited long wait times, scripted replies that failed to resolve problems, and dissatisfaction with warranty coverage.

On third-party platforms, iRobot’s performance was mixed. Their Trustpilot reviews were majority negative, with fewer than 10% awarding five stars. However, the Better Business Bureau gave them an A+ rating, reflecting responsiveness to formal complaints. This again highlights a gap between public review sentiment and official complaint resolution.

Where iRobot stood out most was in their policies, which were the most consumer-friendly of any brand we evaluated. Customers benefit from a 60-day return window, prepaid return shipping for defective units, and no restocking fees. Warranty coverage is standard at one year. These terms earned iRobot the highest policy score in our rankings.

In our live support test, iRobot was slower to connect than the top performers. It took about seven minutes to reach a live agent, though the company did offer a callback option. While this was not the worst showing, it paled in comparison to Shark, Dreame, and Roborock, who connected us to an agent in under a minute.

Bottom line: iRobot offers industry-leading return and warranty policies, but these generous terms couldn’t outweigh the overwhelmingly negative Amazon reviews. Their slow phone response time and reputation for scripted, unhelpful support kept them near the bottom of the list at #5 in our customer service rankings.

#6 – Eufy

Amazon Score: 53% positive/neutral, 47% negative
Policies: Standard—30-day return window, free shipping for defective returns, 1-year limited warranty
Third-Party: 61% five-star ratings on Trustpilot, poor BBB grade
Phone Test: Over 30 minutes on hold with no agent reached (slowest of all brands tested)

Eufy posted one of the stronger Amazon review results in our study, with just over half of customers (53%) describing positive or neutral experiences. Still, 47% left negative reviews, most commonly citing poor communication, warranty difficulties, and repetitive troubleshooting steps that didn’t resolve their issues. One factor that helped their score was Eufy’s habit of reaching out to dissatisfied customers. In several cases, the company upgraded or replaced units after complaints, leading reviewers to update their feedback from negative to positive. This proactive—though reactive—approach improved their sentiment score by about 6 percentage points.

On third-party platforms, results were mixed. Eufy scored 61% 5 star ratings on Trustpilot, the best result of any brand, but their BBB grade was low, indicating weak responsiveness to formal complaints. (Note: Eufy’s BBB rating is under their parent company, Anker Innovations, which manufactures a wide array of products beyond vacuums).

Their policies were in line with industry standards: a 30-day return window, free return shipping for defective units, and a one-year limited warranty. These terms were neither worse nor better than the competition, leaving Eufy in the middle of the pack on this measure.

Eufy’s biggest weakness was in human access. When we tested their support line, it took over 30 minutes of navigating phone menus before we abandoned the call without reaching an agent. Although a callback option was available, it was still the slowest response of any brand tested, which significantly hurt their overall score.

Bottom line: Eufy’s proactive follow-up helped improve their Amazon ratings, and Trustpilot showed them in a relatively good light. But poor accessibility, weak BBB engagement, and average policies ultimately left them at the bottom of our rankings at #6 for customer service.
