The dust bag didn't last me the claimed seven weeks, and the robot's object detection leaves a lot to be desired $499.99 at Amazon Follow ZDNET: Add us as a preferred source on Google. A recent trip took me and my family out of town for 10 days. I like to leave my house as clean as possible before leaving town to ensure I come home to a clean house: fresh sheets on the bed, no dishes in the sink, laundry folded and put away. This last trip was hectic, with three little ones, so while I checked most of my items off my to-do list, I couldn't mop my floors before heading out. Also: These 7 household gadgets were secretly driving up my power bill - unplugging them helped To that end, I delegated the task to the Narwal Freo Pro. I'd set it up and tested it for some time before leaving, but running it daily in my absence would be its biggest challenge yet. In my tests, the Narwal Freo Pro did pretty well at keeping my floors clean. It has fantastic suction on hard floors, does a decent job mopping, and can clean without much intervention. However, it didn't always avoid cords on the floor, the suction performance wasn't as great on carpet, and its dust containment didn't last me near seven weeks. Maria Diaz/ZDNET While it offers a hands-free experience, the Narwal Freo Pro doesn't have a self-emptying dustbin. Instead, it has a dust bag in place of the usual dustbin, which holds dust and debris. The large bag has a one-liter capacity, which is three times the size of a regular robot vacuum's dustbin. The robot has a built-in dust compression system that compresses the debris the robot collects, then dries it with warm air to reduce the possibility of odor developing. While Narwal says this dustbag can go up to seven weeks before swapping it for a new one, your mileage may vary. Mine did. Also: The best smart lock for iPhone users just got a big upgrade - here's why it matters My bag filled up in three weeks of use, but I have a very hairy dog that must have an evil plan to make a carpet out of his hair on my hardwood floors. I ran the Narwal Freo Pro multiple times a week, since I need a vacuum to run at least daily to keep my floors clean, so the bag filled up quickly. Thankfully, this just means that the hair is inside the robot and not on my floor. Maria Diaz/ZDNET I was curious to see how the Narwal Freo Pro would do cleaning my house while my family and dog were gone on our trip. During testing, the robot's obstacle avoidance wasn't the best, though this is understandable at this robot vacuum's price point. Unfortunately, I've had to rescue the Freo Pro a handful of times after it tried vacuuming a sock, tissue, the corner of a blanket, and a few charging cords. Also: Finally, my ultimate smart home setup is complete thanks to this display gadget However, while I was gone, I ran the Narwal Freo Pro every other day, and it didn't get stuck on an obstacle a single time, which was impressive. Being able to leave your robot vacuum to clean your floors while you're away at work or sleeping is one of the best uses you can get out of such a device, yet it's not often possible.

ZDNET's buying advice Maria Diaz/ZDNET I love the feeling of coming home to a clean house. It makes the stress on my shoulders dissipate as soon as I walk through the door. I've had a few robot vacuums offer that clean-home feeling, but most fail to truly deliver on it. I was glad to see that the Narwal Freo Pro delivered this feeling. Also: 7 rules to follow for the best home security camera footage (and places to avoid setup) If you're looking for a midrange vacuum priced between $400 and $800, you can't go wrong with the Narwal Freo Pro. It's especially good if you have mostly hard floors and will appreciate the hands-free mopping feature. The only caveat is that you may have to replace bags more often than others if you have pets, which is a maintenance cost you should consider.
