Can't recommend this one
on June 6, 2026
Posted by: Name
Can't recommend this one. It cleans great and can work on a (limited) schedule, but it keeps disconnecting from the wifi, which is necessary for it to run. Several times a month, I have to reconnect it by opening the app, pressing and holding the buttons on the vacuum, allowing permissions again, and resetting my wifi to 2.4 GHz from my Internet provider account. The problem is not my Internet because my other devices that run off of the same network stay connected. The Do Not Disturb function also doesn't work.

Hi there,
Thank you for taking the time to leave a review.
We completely understand how frustrating it must be to deal with frequent Wi-Fi disconnections, especially when it impacts your ability to use scheduling and key features like "Do Not Disturb". We also appreciate you calling out the extra steps you’ve had to take to reconnect, as we know that can quickly become inconvenient. This certainly isn’t the experience we want you to have, and your feedback regarding connectivity reliability and functionality has been noted. We’ll be sure to share this with our product and technical teams, as insights like yours are incredibly valuable in helping us improve both performance and user experience.
In the meantime, we recommend referring to our troubleshooting guide below, which includes steps that may help stabilize the connection and address the issues you’ve mentioned:

Disappointing!

Gender:Female
Does not keep a charge very long even after charging for 24 hours. Should have 2 brushes, one on each side, stops after only cleaning 3 rooms and doesn’t resume its mapping! Very Disappointing!
No, I would not recommend this to a friend.

Great robot!!!

My Shark is a life saver. The robot vacuums my tile floors and carpet with a touch of a button. The only addedd step I do is mop my floors once a week. Great robot and worth the investment.
I would recommend this to a friend!

Hot, Lost Garbage
on June 24, 2026
Posted by: Zalen
Gender:Male
I bought this in December, and, initially, it worked fine. But then Shark did something to break the software and now when I tell it to clean a specific room it takes a single lap around the outside edge of the entire house, returns to its dock, and plays its silly little victory noise. Much like I imagine the devs did when they broke the software. I am actively trying to get a refund, but you shouldn't buy it at all.
No, I would not recommend this to a friend.

Hi Zalen,
Thank you for taking the time to leave a review and for sharing your experience in detail. We understand how frustrating it must be to see a change in your robot’s performance, especially when it was working well initially and is no longer cleaning specific rooms as expected.
We appreciate you bringing this to our attention, and your feedback is incredibly valuable. It will be shared with our product and development teams so they can review and continue improving both performance and user experience.
To help resolve the issue, we recommend working through the troubleshooting steps in our detailed guide below, which includes checks for mapping, software behaviour, and cleaning modes:
https://support.sharkninja.com/article/RV2300S-RV2300AE-Series-Shark-Matrix-Auto-Empty-Robot-Troubleshooting-Guide?redirect=false

Not for me
on June 29, 2026
Posted by: bill18436572
from Trenton, MI
Gender:Male
We have a mixture of hard floor and low pile carpeted surfaces and this does none of it particularly well. It has a tendency to get stuck under furniture and needs to be rescued frequently. I’m also not a fan of it charging fully before finishing its mission. From the time it starts, fully recharges and completes the program it takes a total of 4-5 hours, most of which is charging. We had a different brand robot vac and it would only charge enough to finish the job before returning to the base and fully charge. The rotating blue end of self cleaning brush has a tendency to get hair wrapped under the capped end and it isn’t very easy to get it cleaned out. On the plus side emptying the dust bin and cleaning the vacuum and filters/base is convenient and well thought out. I like the app and available programming options. I just wish the vacuum could perform the available tasks better. It’s unlikely I would buy again.
No, I would not recommend this to a friend.

Hi Bill,
Thanks for taking time to leave your review.
It’s clear how frustrating this experience has been, especially when the vacuum is not performing consistently across different floor types, getting stuck under furniture, and taking longer than expected to complete a full clean cycle. This is not the level of performance we want for you, and it’s understandable that these issues have impacted your overall experience. We do appreciate you highlighting the features that have worked well, such as the dust bin design and the app functionality. To help address the concerns raised, we recommend following a guided troubleshooting flow tailored specifically to issues with floor performance, getting stuck, recharge behaviour, and hair wrap on the self cleaning brush. This guide walks through each point step by step to help identify and resolve what may be causing the problems.
If the steps do not resolve the issue, there is a short form available at the very end of the guide. Once submitted, our support team will follow up directly and provide any further assistance needed. We’d really value the opportunity to help improve this experience.

Hey there,
Thank you for your feedback.
It's disheartening to hear that your Matrix Robot has gone from working well for 1.5 years to struggling with battery life and making unusual noises, we can understand how frustrating that is, especially when you’re not sure where to turn for support. We’d love to help with both the runtime and noise concerns. Please visit the “Robot and Charging Base” section in the guide below, then follow the steps under “Short Runtime/Battery Life” and “Unexpected Noise.” If the issues continue after completing those checks, simply follow the instructions at the end of the page and we’ll take it from there, including reviewing any warranty options and replacement support that may be available.
