Moosoo RT40 Short Battery Life - No Replacement Purchased 4/21 from Amazon. Battery life now down to 20 minutes runtime max. Customer service says replacement battery no longer available. No help on a 3rd party alternate battery. Really, with a 2 year old product ? Would never buy another Moosoo product. 12/7/23 UPDATE: For those interested in a 3rd party replacement battery, the following Cameron Sino battery will work. Search Amazon for: "Cameron Sino Battery for Liectroux C30B C30B 2D C30B 2D WiFi Robot Vacuum Cleaner Midea M4 PN:Liectroux MD-C30B 2600mAh I installed it in my RT40 and the runtime is now back to normal.

GARBAGE SERVICE for a product that doesn't last!!! Took company 5 months to act on my inquiry which was 2 months before the warranty expired. They finally sent me a new battery because it would not charge properly. After the unit still would not charge, they refused to help. DISGUSTING SERVICE!!!!!

The company is unresponsive to emails The company is unresponsive to emails. I have emailed them multiple times without getting a response. I have purchased 3 cordless vacuums from them and will not purchase another product as their customer service is lacking. Do yourself a favor and look at another brand.

DO NOT BUY FROM THIS COMPANY DO NOT BUY FROM THIS COMPANY! My cordless vacuum broke after six months. The company admitted the motor was defective and said they shipped a new replacement motor. After two months of going back and forth, never receiving the motor they told me to contact Amazon. They said they couldn’t replace it. They obviously had no intention of ever sending it and just kept giving me answers that were not truthful.

BEWARE OF THIS COMPANY Terrible company to do business with. Vacuum Cleaner broke within 6 months. Company did not stand behind warranty. They offered to replace it after I sent a video, however, they claimed they were out of stock and didn't expect shipment for a few months. They would not give me my money back so I could purchase a replacement. Amazon took it back at a considerable financial loss.
