I debated on Mytee vs Orbot for a while. I've got an Orbot that's been bulletproof for 6 years now. However, I decided on the Mytee primarily because they were an advertiser here at the time so that was the deciding factor. My thoughts on the two.
The good: The Mytee looks sharp. I received multiple compliments on it, most being, "Wow that looks expensive!" The tank design is nice and is easier than my Sprayborg. The price point is also reasonable imo.
The bad: The wheels are too close together so it doesn't travel in a straight line as easy as the Orbot. Pad driver also falls off when you move it around, especially up stairs. It also sprays a lot of volume, which can be tweaked with different jets, but it shouldn't have to be imo, design flaw.
Conclusion: I sold it and will be buying another Orbot. If it ain't broke….
