The robot transitions smoothly between floor types and avoids falling down stairs or tumbling off ledges. For focused cleaning, you can set virtual boundaries or target specific rooms.

Design

The EICObot R21 has a sleek and modern design with a circular shape. It measures 12.6 inches in diameter and is 3.35 inches tall, giving it a low profile that can easily fit under furniture. The R21 weighs in at just 4.4 pounds, making it lightweight and easy to carry.

The top surface features one large button for starting and stopping the vacuum. Towards the front are an infrared sensor for avoiding obstacles and a bumper sensor. On the underside are the two large wheels, side brushes, and the rolling brush. The dustbin and filters are conveniently located in the back for easy access.

Overall the R21 has an attractive and functional design optimized for home cleaning. The circular shape allows it to maneuver and turn efficiently while cleaning. The dimensions are compact but leave enough interior room for a 0.3 liter dustbin and the vacuum components. And the relatively light weight enhances portability around the home.

Another robot vacuum cleaner worth considering is the XIEBro HR101. This model has a unique D-shape design that allows it to get very close to walls and corners. It measures 13.7 inches wide by 3.9 inches tall. The low profile allows it to clean under furniture as low as 2.6 inches high. It weighs a bit more than the R21 at 7.28 pounds.

The HR101 features large rubber wheels and an anti-collision infrared sensor on the front. The top has minimal buttons - just power, cleaning mode, and return to dock. The 0.6 liter dustbin and filters are accessed from the back. Overall, the HR101 has a very sleek and modern aesthetic perfect for any home.

Both the EICObot R21 and XIEBro HR101 have attractive, functional designs optimized for home use. The R21's circular shape provides great maneuverability and access. While the HR101's D-shape gets into corners and under low furniture. So they both excel at cleaning thoroughly, just with slightly different approaches based on their shape and dimensions.

Cleaning Performance

The EICOBOT R21 robotic vacuum cleaner does an excellent job picking up dirt, dust, hair and debris on both carpets and hard floors. Its strong 2100Pa suction allows it to thoroughly clean low to medium-pile carpets. The brushes are designed to agitate carpets and dislodge embedded debris. On hard floors like hardwood, tile and vinyl, the vacuum is able to suck up all sorts of dust bunnies, pet hair and crumbs. The side brush helps sweep debris from edges and corners into the path of the main brushes.

Customers report the R21 performs significantly better than previous robot vacuums they've owned, especially when it comes to cleaning carpets. It has no problem picking up pet hair, an area where some robot vacuums struggle. The strong suction is key to its effective cleaning ability. Emptying the dustbin reveals just how much dirt and debris has been removed from floors. Overall, the cleaning performance of the EICOBOT R21 makes it a great choice for homes with lots of carpeting, pets, or dust and dirt buildup.

Maintenance

The R21 requires some periodic maintenance to keep it running optimally. Here are some of the main maintenance tasks:

Filter Cleaning

The R21 has a washable primary filter that needs to be cleaned regularly. Simply remove the filter and rinse it under running water to remove any built up dust and debris. Make sure the filter is completely dry before reinstalling. For best performance, clean the filter every 2 weeks.

Brush Cleaning

Over time, hair and debris can get tangled in the brushes. It's important to periodically remove and clean the brushes so they can keep working properly. Use the included cleaning tool to cut away any tangled hair or threads.

Dustbin Emptying

The dustbin should be emptied after every cleaning cycle. The bin is easy to remove, empty over a trash can, and reinsert. Pay attention to when the bin is full to avoid overflow.

Regular filter cleaning, brush maintenance, and emptying the dustbin are key to maintaining optimal suction power and avoiding clogs or jams.

Noise Level

The EICOBOT R21 operates quietly for a vacuum robot. The normal cleaning mode noise level is around 60-65dB, which is equivalent to the volume of a normal conversation. This makes it easy to run the R21 during the day without it being too disruptive.

Users report that the R21 is quieter in normal mode than the spot cleaning or turbo modes. The spot cleaning mode operates around 68-70dB, while the max suction turbo mode can reach 72-75dB. These higher suction modes are effective for deep cleaning carpets, but will produce more audible noise.

At its loudest settings, the R21 is comparable in volume to a dishwasher or washing machine running. For some users this might be too loud for nighttime cleaning when trying to sleep, but during the day it should not be a major issue. Those sensitive to noise may want to schedule the turbo mode during daytime hours instead.

Overall, the noise level is average and reasonable for a robot vacuum able to provide 1800Pa of suction power on max mode. The R21 strikes a good balance between strong cleaning performance and quiet operation for household use.

Accessories

The EICOBOT R21 comes with a few handy accessories to optimize your cleaning experience.

Extra Filters

The vacuum includes 3 extra high-performance filters to trap dust and allergens. The filters are washable and reusable, so you can simply rinse them out when they get dirty instead of replacing them. This helps cut down on maintenance costs over time.

Replacement Bristle Brush

An extra multi-surface bristle brush comes with the R21. The bristles help agitate and lift debris from carpets and hard floors. When the bristles eventually wear down after heavy usage, you can swap in the replacement brush to keep cleaning performance high.

Extra Side Brushes

Two extra side brushes are included. The thin bristles on the side brushes sweep along wall edges and into corners to help capture debris in hard to reach areas. When the bristles flatten out after months of use, the extra side brushes ensure you can pop on a fresh set.

Charging Base

The R21 comes with a charging base that serves as the vacuum's home station. The base has an outlet prong on the bottom that plugs into a wall socket to deliver power. The robot autonomously returns to the base when its battery runs low to recharge itself.

Pros

• Powerful 2000 Pa Suction: The R21 has a suction power of 2000 Pa, which is strong enough to thoroughly clean carpets and lift deep-seated dirt and debris from hard floors. The boost mode can ramp the suction up to 2600 Pa for even deeper cleaning.

• Large Battery Capacity: This vacuum is equipped with a large 5200 mAh battery that allows it to run for up to 150 minutes on a single charge. You get plenty of cleaning time before needing to recharge.

• Automatic Dirt Disposal: The R21 has an automatic dust disposal station that the vacuum can empty itself into after cleaning. This means you don't have to constantly empty the dust bin yourself.

• App & Voice Control: The EICOBOT app allows you to remotely control and schedule the R21. You can also use Alexa or Google Assistant voice commands to start cleaning or direct the vacuum to a specific room or area.

Cons

• The dustbin is small at 0.2L, meaning you'll need to empty it frequently if cleaning large areas.

• Some users report issues with getting stuck on cords, rugs, or transition strips between floor types. The robot can struggle with navigating these obstacles.

• The app and features are fairly basic. You don't get mapping or the ability to divide rooms into zones. This may be limiting for some users.

• The battery life only provides around 100 minutes of cleaning time. This is on the shorter side for robot vacuums, reducing the amount of area it can cover in one session.
