Battery Life
Customers have mixed opinions on the battery life of the eufy Boost IQ RoboVac 11S, with some reporting it exceeds the advertised runtime while others experience shorter battery life. The vacuum cleaner provides excellent coverage and saves time for users, but a few customers have encountered issues with battery replacement and durability.
Brush Design
Customers have mixed opinions regarding the brush design of the eufy Boost IQ RoboVac 11S. While some users experienced issues with the brush motor and hair tangling, others found the included multitool helpful for cleaning out debris and appreciated the brush guard's rubber piece that corrals dust and debris into the dust compartment. Some customers also noted the robot vacuum's improved navigation on various floor types compared to other models.
Filter Maintenance
Customers acknowledge the importance of filter maintenance for optimal performance of their eufy Boost IQ RoboVac 11S, but some find the process unintuitive as the filters do not release easily and require tools to remove. Despite this, most agree that regular maintenance is necessary to keep the vacuum functioning effectively.
Edge Cleaning
Customers are generally positive about the edge cleaning performance of the eufy Boost IQ RoboVac 11S, with some suggesting improvements for better edge coverage and customization options. The robot vacuum effectively cleans edges and corners using its side brushes, but users recommend removing and washing the brush regularly to maintain optimal performance. Some customers have noted challenges with pet hair and shedding, requiring occasional cleaning of the dust bin. Overall, the eufy Boost IQ RoboVac 11S is praised for its strong suction, quiet operation, and self-charging capabilities.
Suction Power
Customers have mixed opinions on the suction power of the eufy Boost IQ RoboVac 11S, but generally positive. Some customers find it effective in cleaning dust, dirt and pet hair, while others mention that it doesn't clean as deep as a traditional vacuum. However, most customers are satisfied with its ability to maintain clean floors daily and appreciate the convenience of not having to manually vacuum every day.

Anker stands by their warranty and will do what it takes to fix your robotvac or just replace it altogether if it gets too technical.
The filters won’t release with regular poking and prodding and the manual shows an image of it being pulled out from the top wi... Read More
Robovac stops all functions shortly after a button is released when used manually.
Price
The $160 price i paid is quite reasonable with excellent cleaning ability (given it has about 1/10 the suction of a typical canister vac).
Dig through your kitchen drawers, tool boxes or the $2.
If you want a new hepa filter for it every week or two, they will cost you.
Perhaps you would think nothing of spending $850 on a robot.
Shipping
I am very satisfied with the customer service i received and the free parts they sent me to fix my 'rosie.
The one time i left the remote in another room, it didn't start on schedule the next day, though that could have been operator ... Read More
Packaging/appearance
I didn't place the box there the night before, so i had no idea it was actually a lid to another box.
Lo and behold she was under the box!
It did come with two spares, which is nice, but i'm a little concerned about how often i might need to re-order replacements.
Competitiveness
Both vacuum’s appear to do the job, and i would like to compare them:the eufy has two brushes on either side, whereas my roomba... Read More

This really long review is for the eufy 11s max robot vacuum robovac
Posted by a reviewer on Amazon
Please note “max” vs regular 11s
Posted by a reviewer on Amazon
They may look the same but the max uses a different filter and has the higher 2000pa suction
Posted by a reviewer on Amazon
Otherwise the functions and options other than suction choices are the same
Posted by a reviewer on Amazon
Right up front id definitely buy another when it comes time to replace this one
Posted by a reviewer on Amazon
But these stem pieces are only picked up by a vacuum when it comes at the stem with the brush roller pretty much parallel to the stem
Posted by a reviewer on Amazon
That means random directions will more likely get these pesky problems than an organized back forth cleaning approach
Posted by a reviewer on Amazon
Granted it may take a few cleaning cycles or several passes over the same area during one cycle but since the robovac has completed its first 56 cycles i rarely find them anymore or if i do spot one its not for very long
