a customer from Northbrook was looking for a place to bring their Sebo vacuum lceaner for repair service. They performed an on line search and were referred to Kritz Vacuum & Allergy Relief in Highland Park. When they came in with their Sebo vacuum cleaner they told us that the Sebo vacuum has no power. We performed an estimate and confirmed that the Sebo vacuum has very low suction. We determined the reason the Sebo vacuum has lost suction is due to old and dirty filters. We replaced the Sebo vacuum cleaners filters and now all is good.
