This item had VERY poor suction when fully charged when brand new and unused. I tried using it to clean car carpets anyway. Completely switched off after 15 minutes. Execution time, despite the periodic stop (according to the instructions). I charged it fully (took 3 full hours). It then had VERY little suction power as when it was new. I returned for a refund. I would not recommend this product to anyone. Attention potential buyers!
