I had purchased a voucher for 2 hours of residential cleaning with 2 professional cleaner from SierraMaid Cleaning. They only took appointment booking via email and were slow to respond. But evenutally was able to book a weekend appointment. They did an ok job of cleaning. Basically anything I told them that needed cleaning was cleaned. Overall they did vacumming and mopping. However, there was a few area that they missed because I wasnt there to point out the area. I would not use them again if I have to pay full price. But if there's another good deal, I may consider, but I would point out all the areas that needed cleaning ahead of time.
