If it is new and deflating overnight without any visible damage I would lean toward a return or replac, ement rather than a repair. Reach out to the seller and describe what you have tried. If you can capture a short clip of bubbles forming or measure how long it takes to soften they usually process an exchange quickly. To narrow it down before contacting them,, do a valve check. Inflate firmly, close the valve, wet the entire valve area with soapy water, and gently flex it while listening. Bubbles at the cap or where the valve meets the fabric often point to a manufacturing issue. Long lines of tiny bubbles along a seam are also tough to fix permanently. A single pinpoint on a flat panel is the one case that patches well, but patching can complicate returns. If you keep it, clear the ground of sharp bits and set it on a smooth surface, and avoid cranking it to maximum pressure at night since cooler temps make it feel softer by morning.

Adding one thing - Great advice. One extra caution: only wash filters that are labeled washable - many post-motor HEPA cartridges are replace-only and... before rinsing gently tap the foam or felt outside to knock out heavy dust, and while it dries, cut hair off the brush roll and clear the cyclone’s mesh screen if it’s a bagless model. If it’s humid, give the filters a full 24 hours to dry before reinstalling.
