I researched and read many of the reviews on the M330 Pro. I can't see how anybody would give it less than 5 stars. I have owned 5 different robot vacs. One of which I just returned because of its poor third party app which was useless. The Lefant company knows robotics. While this is my first from them, I won't hesitate to buy from them again. It is quiet, quick, and the Lefant App which is THEIR own app and not some cheap third party, is the best. Easy to understand, and navigate. The design of the vacuum is very well thought out. The M330 Pro is a brand new model (go look at their website) and the technology has improved from even a year ago. The aid of both 2G and 5G networks is something you just don't find from anyone else. For the price, this is an absolute MUST BUY. And to make the vacuum even better, the customer service from Lefant is the best.

Eufy 11S Max Replacement Parts Work Well

Size: 20 PACK

For the 11S Max, the parts fit great. Changing out the parts is easy, and the parts are durable. I like that this kit has a new filter for everytime you change out the rotating brushes. Changing out the parts make the eufy vacuum cleaner function better everytime. I can’t tell a difference in the noise level when changing out the parts. Overall, thus is totally worth the money to keep the Eufy running in its best shape.
