Dibea Cordless Stick Vacuum Cleaner - Motorized Brush

Vacuum was used just for 1 year and the owner moved so I'm selling it for him. I tried it and the vacuum is in great used condition but the suction is not very strong (compared to my Dyson). See link below from Amazon. Listing does not include the charger, a common AC/DC adapter 100V-240V. I used my adapter (pictured) to recharge for reference only - it is not included in the sale. Listing also doesn't include any extra brushes as mentioned in the link below. https://www.amazon.com/Dibea-Cleaner-Lightweight-Handheld-Hardwood/dp/B0BZR4VR55/ref=pd_lpo_sccl_2/141-7638800-1264147?pd_rd_w=jKM13&content-id=amzn1.sym.116f529c-aa4d-4763-b2b6-4d614ec7dc00&pf_rd_p=116f529c-aa4d-4763-b2b6-4d614ec7dc00&pf_rd_r=SYVKWHN3GB70FBZG2BXW&pd_rd_wg=pH8kP&pd_rd_r=2a4fc659-fe50-4e1e-9735-1d9a6c29684d&pd_rd_i=B0BZR4VR55&psc=1
