The SPM4650 DSMX SRXL2 Serial Micro Receiver takes the original SPM4648 receiver and adds more value, functionality and fly-by telemetry, while decreasing the size and weight of the already micro sized Spektrum serial receiver. The SPM4650 uses our feature-rich SRXL2 protocol to give pilots a blazing fast serial data connection with up to 20 channels. SRXL2 is a powerful communication protocol that improves bi-directional communication between the radio system and flight controller for added telemetry functionality and flight control configuration right from the pilots Spektrum Transmitter*, all over one signal wire.

The SPM4650 is small, lightweight, and customizable, providing an excellent receiver for even the smallest of applications. It also features a simple bind button so pilots no longer need to carry a separate receiver or bind plug to bind. Dual antennas provide receiver diversity for solid signal and the long coax antennas help to provide maximum signal strength in all orientations for challenging installations where carbon fiber, metal and batteries shield the antenna. And with Spektrum DSMX 2.4GHz RF protocol the Spektrum SRXL2 Serial Micro Receiver provides remarkable range and interference free performance.

$500, not $600. It isn’t worth $600
Color: White
You’re gonna need to put on some glasses and grab a drink for this one. Cons : - Has issues with “muddy mats” brand rugs and mats, along with light mats - It ate my socks - Will molest your standing fans and shoes and pet toys - Castor wheel is a hair magnet along with the “tangle less” floating brush - Mop heads get dirty after just one run of the entire house - It hates charging cables - And dryer sheets PROS: - Smarter than Shark brand vacuums - Excellent management of houses and avoiding most obstacles - It mops and vacuums well - Cleaning is very easy - Cat litter gets sucked up on the strong setting (not the super strong, though that works too) - Battery lasts for vacuuming most of the house - No navigation issues - Doesn’t mess up your furniture - IT WORKS IN THE DARK the floating brush though where the metal shaft sits inside the brush itself and the miniscule space between the spinning part and the brush itself gathers hair like a magnet and will give constant roller brush errors if not regularly cleaned. The castor wheel I swear has more hair than anything I’ve seen. Even the shark didn’t collect it this bad.

Value for Money- Exceptional performance and features!!!!
This vacuum/mop system is wonderful! I highly recommend it. This is bi-far the best vacuum and moping system which effectively cleans my floors and carpet. I've always been on the lookout for anything that can lighten my cleaning load. it’s been a real game-changer for my household routine. The self-washing and self-charging features are a huge win. I no longer have to worry about cleaning the mop or making sure it’s charged; it takes care of itself. It moves around furniture and other obstacles smoothly, rarely bumping into anything. It easily navigates tight spaces and corners, making sure every area gets cleaned. Value for Money: Considering all its features and how well it cleans, I think it’s a fantastic investment. It’s made keeping my home clean so much easier and less time-consuming. The robot vacuum was able to map my house successfully, the battery life is a bit longer than my previous robot vacuums, the suction is also great. I saw it go over crumbs in the kitchen and it picked up without any problems, and also has a mop functionality. It has a functioning app, very easy to use. The vacuum is also very quiet. By far, this is my favorite robot vacuum and I’ve tried many as I do not like to go around the house mopping and vacuuming. 10/10 would recommend this model - worth the investment. Overall I could not be happier with this purchase, my home is the cleanest it has been since I’ve first moved in.

A blessing for “unforgiving” flooring
We bought an 1800s home that was 90% hardwood, but the previous owner made the decision to tear out the hardwood in the kitchen. Unfortunately for us, the flooring we picked to replace it was what I call a very unforgiving. I didn’t realize it until it was too late, but it shows every speck of dust and every muddy paw print. With two dogs, my floors looked like they had not been cleaned in years, but it was being mopped on a daily basis. Enter the Narwal. I’ve included a photo of what the floor looks like today post-clean on a typical winter day in the north (dogs and people running in and out, tracking and mud and snow everywhere). Look at it! It has a shine! In an hour, it will be dull again from the dogs’ next foray into the snowy yard, but right now…glorious! But the best thing is, I no longer care about the dogs tracking up the floor. I can just run the Narwal again. No real extra labor on my part (other than occasionally needing to fill the water container). I want to add a couple of points that I find interesting or that I think people might want to know to make their decision. Both the roller and the side sweeper brushes are meant to prevent hair from getting wound around them. So far I have found this to be true. You can see the videos the manufacturer has provided that show how this works, so I won’t bother to explain it, just point out that I’ve found it does work. I haven’t had to cut any hair out of the roller since I’ve gotten it, and that was previously a weekly thing. It does not self empty after vacuuming. However, it compresses the hair and dirt to take up less space. So while I was emptying my big self-emptying canister (on my Shark) about once a month before, I’ve only actually emptied this smaller dust bin once every one to two weeks. Initially, I was worried that this meant it wasn’t picking up as much debris and hair, but upon review, I discovered the compression factor they describe. You also have the option of using dust collection bags that you can take out and dispose of. To be more environmentally friendly, I have not chosen that option, but for people that may have issues with dust, I’m glad it is an option. It self-cleans and dries the mop pads quite well. I did pick up replacements so that I could wash them, but I’ve needed to wash them with far less frequency than I expected. When I do pull them off to wash, I don’t notice any odor like I was expecting. The mop water is used to both clean the floor and wash the mop pads. I think the majority of the water usage is to clean the pads, however. So you will need to refill that every 2 to 3 mops probably depending on how big your house is. You can use it with or without Narwal cleaner - do not use other cleaners, or you risk the device dying or messing up your floors due to over foaming. My one tip is to use any leftover mop cleaner you may have from your regular mopping, and add a capful into the dirty water bin after you empty and rinse it each time. Because if you do not empty that out every day, the stagnant water WILL be stinky. A little scented floor cleaner has seemed to improve that dramatically for me. Is it expensive? Yes. Is it worth it? RESOUNDINGLY yes. I no longer have to kill myself to have clean floors. And that is the best gift to give myself.

Amazing robot helper
Color: White
I’ve been using this robot vacuum for about a month now, and I have no regrets about buying it! It’s noticeably quieter than my previous robot vacuum, and the mopping performance is excellent. I really like that it has two large water tanks—one for clean water and one for dirty—which makes a big difference as it easily covers my entire house on a single run. I don’t have carpet, so I can’t speak to how it performs there, but for vacuuming and mopping tile and hard floors, it absolutely deserves high praise. The battery is another big plus—it can clean my whole house before needing to return to the base to recharge. The app is fantastic. The mapping is very accurate, and there are plenty of cleaning options to customize different areas of the house. The initial app setup did require some help, but customer support was quick and very helpful. Overall, I’m a very satisfied customer and would definitely recommend it!

Awesome robo-vac/mop with rotating mop head/no pads.
Size: E25 Black
I owned a Narwal Freo for 1 year and it died right after the warranty period was up. Tried replacing the battery but that did not fix the issue so I had to purchase another one. I noticed this eufy had high reviews and the 1 star reviews seemed to be just isolated issues so I purchased this one. Right away I noticed that the instructions/setup was much more simple. Second this one has a big wide mop roller on the front and after mopping I didn't see the mop streaks in circular patterns on the floor like I did with the Narwal as it had two rotating mop heads on the front so the single mop roller seems to be a better solution. Setup consisted of removing protective wrappers off of the tanks and base station, filling up the clean water tank, installing the detergent bottle and plugging it in. Next I downloaded the app and connecting the vac/mop to my network. This was SIMPLE to say the least. From there I could have just clicked clean on the app and it would clean the entire house. However, mapping gives you more flexibility when planning your cleaning ritual. You can define no go zones and clean rooms in any order you choose. I have a shedding dog so I have a separate robovac to clean up the dog hair prior to vac/mopping. This is a MUST with any robovac/mop combo as the dog hair on the floor will mix with the water and detergent and eventually prevent the mop from doing a good job. It will make a mess in the bottom tray of the base station too. I learned this through experience and reading all the one star reviews from customers. Robovac only cleaners last a LONG time. I had one that is still working great for over 3 years. All I had to do was replace the battery so it doesn't have to pause the job to recharge. So the mapping only took 4 minutes and it was pretty accurate. After the mapping I defined the room boundaries and renamed the rooms. Next I sent it off to clean and it did a FABULOUS JOB! No streaks and the floors are clean. The noise level is really low and more quiet than the Narwal. The other thing I noticed is it didn't use up much water to rinse the mop while cleaning. The Narwal used a lot of water and I was always dumping dirty water and adding fresh. I will always have a robomop and robovac as they save me so much time by not having to do this job twice a week. Connectivity to my network is excellent as it's in a location far from the router. This vac/mop is a good value for the money if IT LASTS BEYOND 1 YEAR. I will update this review as necessary and if it fails right after the warranty period I will report and downgrade this review to 1 star. These companies need to learn the importance of reliability and correct these issues. When I first reviewed the NARWAL it had almost a perfect 5 star review from all customers. After the year was up and it failed that star rating went down to 3+ stars. Most reviews reported their robovac/mop just died like mine did after the warranty period. I downgraded my review and reported the issue. I'm hoping this one will last because at the moment I am VERY satisfied with it like most customers. This model has been on the market much longer at the time of purchase so I would suspect if there were any reliability flaws they would have been addressed and corrected by now. We shall see. At this time I highly recommend!!
