Hi dear customer, Thank you for sharing your experience with the Shark Detect Pro Cordless Vacuum. We're glad to hear there are aspects of the vacuum you enjoy, but we’re sorry to learn it shuts off when switching to different tools like the hand vac or wand. That certainly shouldn't be happening, and we understand how disruptive it can be. We’d like the opportunity to help troubleshoot this further and ensure your unit is functioning correctly. Please reach out to our Customer Support team at 1-855-427-5127 so we can assist you directly. Kind regards, Shark Clean
