While there are a number of good robotic vacuums that mop, the mopping feature almost always underwhelms, that is why I prefer a separate robot that is just for mopping. In this post, I'm going to compare two fantastic robotic mops, the ILIFE w450 vs w400. Both of these Shinebot models have rotating brushes, separate clean and dirty water tanks and smart navigation, but what separates them and makes one best? Let's dive in.

These are two interesting robot mops from iLife. Between the two robots, the W450 offers more advanced features, including app control for better customization, smarter navigation and a cleaning solution for shinier floors. The W400 floor washing robot is also a good buy, because even without bells and whistles it still has the ability to wipe dirt and smudges off of your floors, leaving them significantly cleaner, and it comes at a cheaper price. If you\u2019re more concerned about price, consider the W400. But if you want it all; better navigation and better cleaning with a detergent for stubborn stain removal, plus app control and smart features, then the Shinebot W450 is your robot. It\u2019s certainly a better buy because it outperforms the W400. Product Overviews iLife Shinebot W400 iLife Shinebot W400 is the most basic model and the first product in the iLife W series. It\u2019s a budget-friendly floor washing robot with a unique mopping power. It uses two separate water tanks, a microfiber roller and a rubber scraper to mop up stains from a variety of floor types. This robot is also equipped with an excellent battery, decent suction power, and impressive laser navigation capabilities for obstacle avoidance and efficient cleaning. The W400 floor washing robot mops with only clean water (no cleaning solution required) and yet it leaves your floor noticeably shiner and cleaner than before. As an entry-level robot, the iLife Shinebot W400 doesn\u2019t have app control and isn\u2019t compatible with Alexa or Google Home, but it does come with a remote control and gives voice alerts, plus a 1-year warranty from iLife.

First off, it has everything you get in the iLife W400; two separate water tanks, a microfiber brush roll, a rubber scraper, decent suction power, excellent battery life and high cleaning effectiveness. However, the W450 is able to provide better cleaning because unlike the iLife W400, it uses a cleaning solution to get rid of tough stains. It also has an upgraded navigation technology; in addition to the laser sensors, the W450 also has an upgraded Panoview navigation technology for better systematic navigation. And lastly, this robot is Wi-Fi enabled and compatible with the iLifeHome app, which includes more customizable options for personalizing your cleaning.

But they are much taller than the average robot, probably due to the two tanks for clean and dirty water. The robots measure 11\u201d W x 11.5\u201d L x 4.6\u201d H and weigh about 7.3 pounds. 4-step cleaning process These two floor washing robots both follow the same 4-step cleaning pattern, which iLife refers to as the TidalPower cleaning system. They both start off with spraying clean water on the floor. Then, using a microfiber roller brush, they roll over the water, scrubbing off dirt and debris in the process. Next, the water on the floor will be sucked into their dirty water tanks, and finally, a rubber scraper off by cleaning any remaining mess on the floor. Separate water tanks The W450 and W400s both have separate tanks for clean and dirty water. The 850ml clean water tank stores the water used for cleaning, while the 900ml dirty tank stores the water collected after cleaning. A full tank of water is sufficient for mopping up to 400 sq ft. in about 30 to 40 minutes. Built-in drop sensors Similar to most robotic cleaners out there, the W400 and W450 both have built-in sensors for intelligent navigation and drop sensors to avoid stairs and prevent a catastrophic fall. However, neither of these robots have smart mapping technology, and therefore they\u2019re both unable to \u201clearn\u201d and \u201cremember\u201d the layout of home during future cleaning. Quiet operation Both robots are reasonably quiet and won\u2019t disturb you at all. The decibel sounds are not specified, but they\u2019re quiet enough for you to carry on with normal conversations, watch TV or do practically whatever you want in the same room that\u2019s been cleaned. Multiple cleaning modes Each of the robots has a control panel with a few buttons for getting it started and selecting your preferred cleaning mode. There is a \u201cClean\u201d button, which prompts the robot to start a cleaning cycle. And there is a \u201cMode\u201d button for selecting one of the four different cleaning modes; Area, Path, Spot and Edge. The Path Mode cleans the entire floor while avoiding obstacles, the Spot Mode mops deep cleaning specific spots on the floor. With the Area Mode, the robot only focuses on the area directly in front of its starting point, and the Edge Mode is for mopping only edges and corners. Battery capacity Both robots have similar battery capacity, with 300 minutes charging time and a maximum of 80 minutes cleaning time depending on cleaning settings. It\u2019s also important to note that these robot mops do not have the automatic recharge feature that is seen in many robotic vacuum cleaners. With the Shinebot W400s and W450, you will have to manually pick them up and return to the charging dock for a recharge. Voice alerts To aid with interactive operation, these robots are equipped with voice alerts. They don\u2019t connect to Alexa or Google Home, but have their own integrated voice commands for giving important updates. For instance, during a mopping cycle you may hear voice alerts like \u201cPlease check the clean water tank,\u201d \u201cLow battery,\u201d etc. These are very helpful alerts, but you can only hear them if you\u2019re in the same room with the robot. Warranty These two robots both come with a 12-month warranty from iLife. Key Differences Laser SLAM vs Visual SLAM To enable smart cleaning, the W400 and W450 are equipped with sensors for advanced obstacle avoidance and navigation. However, the two floor washing robots are not built the same in this area. The W400s has an integrated SLAM navigation, while the W450 robot mop features a more powerful VSLAM technology for better intelligence and smarter navigation. Remote control vs App control Another aspect where there is a notable difference between these gadgets is the control options. For the W400, the control options include the control panel on the robot and additional remote control. The W450 also has a control panel on the robot, but uses the iLifeHome app for convenience. From the app, you monitor your robot from anywhere and get more options for customization such as adjust travel speed, water output, brush roller speed, etc. Price tag As expected, these gadgets have different price tags, with more than $100 difference in price. The W450 obviously costs more than the W400. iLife W450 vs W400: How do they perform? When it comes to cleaning performances, these two robots are almost evenly matched, but the W450 takes the lead. They are both excellent mopping robots, actually they are among the best mopping robots on the market. The sensors and laser navigation of these robots are excellent, they are able to efficiently avoid obstacles, including carpets and rugs. When approaching an obstacle, the robots will slow down and change direction, which is very impressive. However, you may want to move some delicate items like toys out of the way before sending out the robot(s), as this ensures a seamless clean. Each robot sprays water from the clean water tank onto the floor, scrubs with the microfiber brush roll and suck up the water. Both the W400 and W450 leave floors noticeably cleaner than they met it, this is also pretty evident from what you\u2019ll find in the dirty water tank after each cleaning. Their water tanks may be small, but it\u2019s enough to clean up to 1500 sq ft floor. This is truer for the W450 because it has adjustable water flow levels and mopping speed. These robots do an impressive cleaning job, but they do have a couple of drawbacks. First, the suction force is not nearly enough because they do not pick up all the water they put out and tend to leave small puddles and wet spots in a few places, which will have to be manually mopped up by you. Also, they are better at cleaning laminate and wooden floors than tiles. And before each mopping, you will need to prepare your floors by running a robot vacuum to sweep up debris, since these robot mops don\u2019t vacuum like the Roborock S7. One last note, the Shinebot W400 and W450 are best for cleaning moderately dirty floors, and not for mopping filthy floors that have been neglected for several weeks or months. Ongoing Maintenance These robots do require some maintenance to keep them running. Despite being automatic mopping robots, you do need to prepare them for a mopping cycle and also clean out the gadget and charge it after every mopping session. To prepare it for cleaning, make sure the dirty water tank is empty and refill the clean water tank with fresh water. Also make sure the robot mop is fully charged and the microfiber roller brush and the scraper are properly attached. Then push the \u201cClean\u201d button and select your preferred cleaning mode. This is relatively very easy compared to cleaning the robots after. After each mopping session, iLife recommends that the dirty water tank should be promptly emptied and washed under running tap water. The roller brush, scraper and filter also need to be washed under running water. Fortunately, removing and fixing these parts of the robots is easy. And the W450 robot mop comes with a floor cleaning solution, a cleaning tool and a replacement roller. After washing the parts of the robot, they should be left to air dry before recoupling. Also remember to remove any remaining cleaning liquid and rinse out the cleaning solution reservoir, it\u2019s important that you store the robot without any fluid in it. This may come across as too much work, but it\u2019s actually not as bad as it sounds, especially when compared to scrubbing the floor with a regular mop and emptying the skanky mop buket. A couple of alternatives to consider While the iLife robots are great mopping robots, they\u2019re certainly not for everyone and there are some great alternatives to consider. iRobot 240 Braava Robot Mop - something cheaper for smaller areas For starters, if you want a cheaper robot mop with excellent features and more-than-decent cleaning performance, then the iRobot Braava Jet 240 is a solid choice. At $129, this robot mop is great at cleaning light to medium stains using warm water, cleaning solution and cleaning pads and works on a variety of hard floors. Its compact size permits it to smoothly drive under furniture, below cabinets, and into tight corners, unlike the bulky iLife Shinebot series. The lower price tag of the iRobot Braava jet makes it ideal if you\u2019re working with a small budget and it does a good job. However, it\u2019s worth mentioning that the robot uses disposable pads therefore you\u2019ll have to factor in the cost of always purchasing reusable cleaning pads and a cleaning solution. As opposed to the iLife Shinebot W400 robot mop, which has a reusable cleaning pad and requires no cleaning solution. You can also check out the Braava M6 - a more premium model with smart mapping and imprint link. Roborock S7 Robot Vacuum and Mop - Top pick for a vacuum robot & mop combo Another excellent alternative to the iLife Shinebot W series is the Roborock S7. This is a high-end robot vacuum and mop combo with simultaneous vacuuming and mopping, plus automatic real-time mapping capabilities. This robot has some very advanced features like the sonic mopping system for scrubbing off dried dirt and tough stains, and superior suction power to automatically mop hard floors and vacuum carpets in one cleaning session. Plus, it returns to it\u2019s charging dock for a recharge. It\u2019s also compatible with Alexa and Google voice controls and connects to the Roborock app for assessing a list of exciting customizable features, including no-go zones, no-mop zones, room-specific cleaning, real-time mapping, etc. As a premium robot, Roborock S7 is above the $600 mark, but it\u2019s a top-tier gadget and a great investment if you have the budget for it. FAQ section Will the W400 and W450 also vacuum the floor?These robots are designed to only mop the floor and not sweep like robot vacuums. Therefore don\u2019t expect them to do any form of vacuuming. However, they are able to pick up some pet hair and dust particles using the spinning brush.Do you need to sweep first?Yes, before sending out any of the robots, it\u2019s important to first run a vacuum robot to sweep up debris to prepare it for mopping. Doing this will give you a much shinier and cleaner floor after each mopping.Can we use our own cleaning solution?No, you should not because iLife recommends that you use only their cleaning solution for the W400s and W450. The Shinebot W400 doesn\u2019t require any cleaning solution, since it\u2019s designed to clean with just water.\u00a0\u00a0What is the difference between W400 and W400s?iLife Shinebot W400 and W400s are basically the same robot and function the same way The only difference is the W400s is compatible with the ILIFE app for better cleaning controls such as water flow and brush speed. Final thoughts The iLife Shinebot W450 and W400 are two robot mops with very similar design features, and they both provide good robotic home cleaning. However, the iLife W450 is more advanced than the W400 and also costs more than the W400, which isn\u2019t a surprise. While the W400 has only the most basic features, the W450 comes with a couple of smart features, making it the more efficient and better robot. Therefore, we recommend the iLife Shinebot W450, the extra investment is certainly worth it.
