All returns must be requested and approved by AceVacuums before the item is sent back. Unauthorized returns may be refused.
Standard return window
Eligible items should generally be reported for return within 30 days of delivery unless another condition is stated on the product page, invoice, or at the time of purchase.
Condition matters
Original packaging, manuals, accessories, cleanliness, and overall condition affect whether a return can be accepted and on what terms.
Opened or used items: Opened, installed, assembled, or used products may be subject to inspection, reduced refund eligibility, restocking fees, exchange limits, or denial depending on category and condition.
Non-Returnable or Final-Sale Items
Certain products may be non-returnable or final sale depending on category, condition, installation status, or product-specific rules.
Damaged, Defective, Incorrect, or Missing Items
If an order arrives damaged, defective, incomplete, or incorrect, contact AceVacuums as soon as possible after delivery. The current live policy page already combines shipping and return expectations, so this section clarifies the issue-reporting path customers most often need. :contentReference[oaicite:1]{index=1}
What customers should do
- Inspect the shipment promptly
- Keep all original packaging
- Take clear photos if damage is visible
- Provide the order number and issue summary
Why prompt reporting matters
Problems reported quickly are easier to document and investigate. Delayed reporting can reduce available resolution options depending on the issue and the carrier timeline.
Refund Policy
Refunds are issued after inspection
Refunds are generally issued only after the returned item is received, inspected, and approved by AceVacuums.
Possible deductions
Depending on the circumstances, original shipping charges, return shipping costs, or restocking fees may be non-refundable or deducted where permitted and appropriate.
Refund timing
If approved, refunds are generally issued back to the original payment method. Timing may vary based on inspection completion and payment-provider processing.
Exchanges
Eligible exchange requests may be approved based on item condition, replacement availability, return reason, and whether the replacement is the same item or a different product.
Return Shipping Costs
Unless the return is due to an approved seller error or an approved damaged/defective item claim, the customer is generally responsible for return shipping costs.
Store vs Online Orders
In-store purchases may be subject to different procedures than online orders. Customers should follow the instructions on their receipt, invoice, or from AceVacuums staff when applicable.
