Budget Vacuum Surprise
Size: Freo S, Size: Freo S
I wasn’t expecting much from a budget robot vacuum, but it really surprised me! I’ve owned a few high-end vacuums in the past, so I was skeptical about how this one would perform, especially given its price. But honestly, it handles my apartment like a pro. The suction power is great enough for my place. It picks up everything—pet hair, dust on both hardwood floors and the rug. The dock is simple to use, and the best part is I don’t have to worry about it too much. Just clean the mop pads every now and then, and that’s about it. The dustbin is large enough that I don’t have to empty it after every cleaning, which is a big time-saver. For someone like me, living alone with little time to clean, the Freo S is perfect. It gets the job done without the extra features of pricier models. If you want a reliable, budget-friendly vacuum, this is a great choice.

Hands off cleaning robot vacuum is the best
Size: Freo S
I have been wanting this kind of vacuum for a long time, and my husband bought this for me as a gift. This is excellent combination of vacuum and mop in one. Also has large self emptying base, precise navigation, app control and smart scheduling. The vacuum is sturdy, and very functional. Love my vacuum, it helps me a lot with cleaning. Highly recommend.

Fantastic price for such great value
Love love this vacuum l!!!
Love that it’s easy to find replacement parts and for every part you’d need.
It does a fantastic job mapping out the floor and rooms. You can see where it’s been on the map and if you’re mopping, that feature makes it great because you know where you can go ahead and mop. It’s SO MUCH QUIETER than the Rumba and the Shark brand. It gives you the option to select rooms that you want vacuumed without having to do all rooms, it does use a bag and that concern me at first because I didn’t won’t to buy bags.
These bags last for a few months at a time and I’ve got an indoor cat so that means lots of hair.
It does an awesome job going anywhere it needs too and does great at picking up. It’s not large size base and fits nicely in a one foot area.
Over all I would definitely recommend and buy again from this company, the price and value to me is way better than the other Big Brands.

Replacement parts
I wish this package included an extra dust bag or two. I wasn’t paying attention when I ordered it alongside my new Eufy RoboVac.
