I've owned this for 6 months and also own a Terravac by Prolux. Upon 1st inspection, I could tell this was made of low quality plastic material compared to the Terravac, which is awesome. I should have returned it but decided to give it a chance. After 6 months use, the main brush has stopped picking up anything and there's no instructions on how to fix the issue. I tried taking everything apart to the point of breaking the main brush roll. I would not recommend Prolux anymore.
