VEPP-2000 is the only electron-positron collider operating with a round beam that permits to increase the limit of beam-beam effects. VEPP-2000 is the compact collider with circumference of 24.39 m which has record design luminosity of 1 × 1032 cm−2 s−1 per bunch at energy up to 1 GeV and record achieved luminosity of 5 × 1031 cm−2 s−1 at energy of 500 MeV, magnetic fields in superconducting solenoids is 13 T and 2.4 T in the bending magnets. Col-lider complex experimental program of 2019-2021 was focused on several energy ranges. Energy range was (180-300) MeV in the second half of 2019, in the first half of 2020 we worked in (935-970) MeV, in the first half of 2021 that was (970-1003.5) MeV. Data taking was carried out by CMD-3 and SND detectors, the operation efficiency is compared with previous runs. Luminosity was limited by beam-beam effects. 2021 year was clouded by vacuum accident and subsequent intensive degassing using beam synchrotron radiation.
