WARRANTY 

 

Bacharach warrants this product for 1 year from the date of purchase indicated on the 
original sales receipt. The warranty covers all parts within the unit, but excludes damage to 
the unit caused by misuse or mishandling. The unit’s motor brushes carry an extended 
warranty of 5 years. 

 

If the unit is in need of warranty service within 1 year of its date of purchase, it will be 
replaced with a brand new one via our over the counter (OTC) exchange program. To obtain 
a warranty replacement unit via the OTC exchange program, the following steps must be 
followed: 

 

1) 

Return the unit to the wholesaler from whom it was purchased, along with proof 
of purchase (original or copy of sales receipt). 

 

2) 

If the wholesaler determines the unit is eligible for OTC exchange, it will be 
replaced with a brand new one. If the failure is determined to have been caused 
by customer misuse or mishandling, the warranty will be voided. 

 

3) 

The wholesaler should then contact our Customer Service Department for a 
return goods authorization (RGA) in order to return the defective unit and have 
an order entered for its replacement. Proof of purchase will be required in order 
to process the RGA. OTC exchange units are processed as no charge orders.
