Its compact charging station, which is 6.5 inches (16.5 cm) wide, includes a recess at the back for cable storage. While the charging station requires some clearance on either side against a wall, its small size makes this easy to accommodate.

The robot vacuum features a minimalist design with a single button on top to activate it (with an on-off switch underneath for a more permanent shutdown), a sleek, tempered black glass surface, and infrared sensors at the front to help it navigate obstacles.

Underneath the RoboVac 11S ultraslim Strong robot vacuum, you’ll find a pair of counter-rotating side brushes and a 14.5 cm rolling brush. The dust box, with a capacity of 0.15 gallons (0.6 litres), easily slides out from the back of the vacuum. However, no warning light indicates when the dust box is full. Instead, a decrease in performance is a reliable indicator that it requires emptying.

Getting the RoboVac 11S ultraslim Strong robot vacuum up and running is a breeze. Attach the side brushes, charge the unit, and it’s ready. The vacuum offers five cleaning modes: Auto, which enables the robot to move from room to room while cleaning; Spot, for targeted cleaning in specific areas; Edge, which focuses on cleaning along walls for 20 minutes; Single Room, which cleans a single designated room; and Manual, where directional buttons on the remote control allow you to guide the robot’s movements (back, forward, right, or left).

Furthermore, the RoboVac 11S ultraslim Strong robot vacuum provides three power levels: Standard, BoostIQ (a combination of Standard and Max power when transitioning between hard floors and carpets, available only in Auto or Single Room mode), and Max.

Scheduling cleaning sessions is simple. You can easily select the desired start time using the remote control by specifying the hour and minute. However, it’s worth noting that there is no option for alternate-day or twice-daily cleaning. Nevertheless, daily vacuuming should be sufficient for most users. The vacuum also comes with extra filters, two additional side brushes, and cable ties to help manage power cords and keep them out of the vacuum’s path.

  • Adequate suction for most jobs
  • Quiet in use
  • Takes a random path around the room
Eufy RoboVac 11S ultraslim Strong robot vacuum Performance.

The Eufy RoboVac 11S ultraslim Strong robot vacuum can handle larger particles commonly accumulating in a home. It effortlessly picked up dry oats from medium-pile carpet and hard floors without requiring higher suction settings. It also effectively collected finer dust made from flour and cookies on hard floors. However, when picking up fine dust from the carpet, the RoboVac 11S struggled. Even on the Max suction setting, it couldn’t extract the dust pressed into the carpet fibres by the wheels.

The cleaning pattern of the RoboVac 11S ultraslim Strong robot vacuum may appear random at times, with it moving in straight lines, seeking out room edges, or even travelling in circles. However, this Bounce Navigation method ultimately ensures that the entire room is cleaned, albeit sometimes taking longer. The robot vacuum occasionally faced challenges manoeuvring around objects, particularly low-level items like deep-pile rugs, piano pedals, and pet food bowls.

During testing, even after prior vacuuming, the RoboVac 11S ultraslim Strong robot vacuum picked up additional dust, pet dander, and human hair from the edges of rooms. However, the rolling brush tended to tangle with the hair. While the rotating brushes accumulated little dirt, a few bristles became slightly bent or twisted during testing. It’s advisable to regularly check the condition of the brushes to ensure efficient cleaning.

In terms of noise, the RoboVac 11S ultraslim Strong robot vacuum is relatively quiet during operation. On the Standard mode, it measured 55 dB while cleaning hard floors and reached 60 dB on the Max mode. This is comparable to the sound of a dishwasher mid-cycle, which is generally acceptable.

There is no alert system to indicate when the dust box is full, so users must remember to empty it or watch for decreased cleaning performance. However, emptying the dust box is a simple process. It can be easily slid out with a button, flipped open, and emptied the dust in one motion. Finer dust may accumulate in the box’s corners but can be brushed out using the provided cleaning tool. The cleaning tool also maintains the rolling brush and filters, which should be done every week.

Eufy RoboVac 11S ultraslim Strong robot vacuum Battery life.

The Eufy RoboVac 11S provides a cleaning time range of 50 to 100 minutes, depending on the cleaning mode and power level selected. During testing, it exceeded the manufacturer’s claim by lasting 105 minutes on standard cleaning before the battery indicator changed from blue to orange, indicating the need for a recharge.

Unfortunately, the RoboVac 11S does not include a battery level indicator that provides detailed information about the remaining charge. This can be disappointing for users who prefer more precise battery status updates.

However, it is worth noting that the battery recharging time was faster than Eufy’s stated claim. It took approximately 4.5 hours to fully recharge the battery from empty, which is a quicker charging time than what was initially advertised.
